Saphyre has launched perpetual futures trading on Sei Network, covering stocks, gold, currencies and crypto, with invite-only access and fees of 0.025% to 0.05% per trade.
@saphyre has launched perpetual futures trading on @SeiNetwork, adding a derivatives venue to what is already the chain's busiest exchange. Perpetual futures are contracts that let traders bet on price moves with no expiry date. Saphyre says users can trade stocks, gold, currencies and crypto through the product.
How the Saphyre perps exchange worksTrading fees range from 0.025% to 0.05% per trade, according to the exchange's site. Orders are handled by Monaco's trading engine.
Access is invite-only. Traders who used the public test version before the October 21 cutoff get in immediately and receive one invite code to share. Every $250K in live trading volume unlocks another code, which ties wider access to how actively users trade.
Perpetual contracts have no settlement date, so traders can hold long or short positions without rolling them over. Positions are typically kept in line with the spot price through periodic funding payments between longs and shorts, a mechanism also used in the regulated SEI contract described below.
Saphyre's position on SeiSaphyre is the dominant trading venue on the network. DefiLlama data shows it with $5.97M in daily spot volume and $16.21M in total value locked (TVL). Crypto Briefing reported that Saphyre handled about $276 million of $278 million in monthly DEX volume on Sei, with the network's cumulative DEX volume reaching $15.9 billion. The exchange evolved from DragonSwap, according to the same report.
That concentration cuts both ways. Crypto Briefing noted that when one exchange processes nearly all monthly volume, the network's trading activity depends heavily on that single protocol. Some analysts have also questioned the exact share: DiarioBitcoin cited DefiLlama data putting Saphyre closer to 83% of monthly volume, depending on how the periods are compared. Methodologies differ, so figures vary by tracker and date.
The launch comes as derivatives exposure to $SEI is also expanding elsewhere. OG.com Markets, a CFTC-regulated platform operated by Nadex, listed a USD-settled SEI perpetual futures contract, which ChainCatcher reported was self-certified on October 8. That product is a separate, regulated offering for US investors and is unrelated to Saphyre's onchain exchange.
Perpetual futures are leveraged products and carry significant risk, including rapid liquidation during volatile moves. The invite-only rollout suggests Saphyre is limiting early access while it scales the product.

A MiCA white paper for Sei Network's $SEI token has been filed by OKX Europe Limited, covering 30 EEA countries. It is a disclosure, not regulatory approval.
A MiCA white paper for Sei Network's $SEI token has been filed for public record in Europe by OKX (@okx) Europe Limited. The document supports the admission of SEI to trading on OKX's platform and covers 30 countries in the European Economic Area (EEA). It sets out the token's utility, risks and holder rights. The filing is a disclosure, not regulatory approval.
What the SEI white paper coversThe white paper is published by OKX Europe Limited, not by the SEI project itself. According to the document hosted by OKX, the white paper is published solely in connection with the admission to trading of SEI on the exchange's platform. It also states that no public offer of SEI tokens is being made and that the admission involves no subscription, sale or fundraising process.
The paper includes a section on risks, including those tied to the admission to trading. It names OKX Europe Limited as an authorised crypto-asset service provider (CASP) operating in the European Union. OKX says its MiCA licence from the Malta Financial Services Authority dates from 27 January 2025 and gives it access to all 30 EEA countries, which is why the SEI filing reaches the same footprint.
Why a filing is not an approvalUnder the EU's Markets in Crypto-Assets Regulation (MiCA), white papers for most crypto-assets are subject to notification rather than prior approval. Law firm CMS notes that competent authorities must not require any prior approval for crypto-asset white papers before their publication. The notified information is passed to the European Securities and Markets Authority (ESMA), which makes the white paper available in a public register.
MiCA also requires a disclaimer on the document. The SEI white paper states that it has not been approved by any competent authority in any EU Member State and that OKX Europe Limited is solely responsible for its content. ESMA has itself noted that investors should not overrate the protection MiCA provides, and has since proposed clarifying when a white paper counts as "duly notified" in its response to the European Commission's review of the rules.
For $SEI holders and traders in Europe, the filing is a transparency step tied to the token's availability on a MiCA-licensed venue. It does not amount to a regulatory endorsement of Sei Network (@SeiNetwork) or of the token.

Sei Network (SEI) now has 2,510 tokenized real-world asset holders, up about 24% in 30 days, as monthly RWA transfer volume nearly triples to $18.8M, per rwa.xyz.
Sei Network is drawing more holders and more activity in tokenized real-world assets (RWAs), even as the total value on the chain has barely moved. @SeiNetwork now counts 2,510 holders of tokenized RWAs, up about 24% in 30 days, according to rwa.xyz data.
Monthly RWA transfer volume on the $SEI chain nearly tripled to $18.8M, while total value held steady at about $291M. The growth is in the number of users and the pace of movement, not in assets under management.
Ondo's USDY dominates the value held on Sei@Ondo accounts for about $260M, or 89%, of the total through its US Dollar Yield token (USDY). The product is backed by short-term US Treasuries and bank deposits, and it was the first tokenized Treasury product to launch on the network, according to TheStreet. That launch took place in July 2025.
The concentration is notable. With nearly nine-tenths of the value tied to one issuer, Sei's RWA footprint depends heavily on demand for a single yield-bearing dollar product.
Credit and hedge fund products add smaller slices@Securitize holds about $15.6M through one Apollo credit fund. CoinDesk reported that Securitize introduced the Apollo Diversified Credit Fund, a tokenized feeder fund of Apollo's private credit vehicle, to Sei ahead of KAIO's expansion to the chain.
KAIO (@KAIO_xyz) holds a similar amount across funds from Hamilton Lane, Brevan Howard, and Laser Digital. CoinDesk described KAIO as backed by Brevan Howard and Nomura's Laser Digital, with tokens available to institutional and accredited investors for onchain subscription, redemption and reporting.
Access restrictions on these products may limit how much activity they generate. Crypto outlet Tron Weekly noted this week that access rules and actual investor demand will shape the economic impact of the network's tokenized fund offerings.
For now, the data points to a growing but narrow RWA base on Sei: more wallets and faster turnover, built mostly on one Treasury-backed token.

Sei Network’s decentralized exchange volume has reached $15.9 billion in cumulative terms. The milestone landed on October 19, 2026, and puts the trading-focused blockchain within shouting distance of the $16 billion mark.
The numbers behind the milestone
Sei is a Layer-1 blockchain that emphasizes low-latency execution, meaning trades confirm quickly enough to suit active traders. Over the 30 days leading up to October 19, Sei recorded $278 million in DEX volume.
Saphyre, the chain’s leading decentralized exchange, accounted for about $276 million of that total. Every other DEX on Sei combined handled roughly $2 million.
Sei’s 24-hour DEX volume currently sits at $6.61 million, up 15.41% on a weekly basis.
Total value locked, the pool of assets deposited into the network’s DeFi applications, stands at approximately $31.71 million. The past month’s trading volume ran to nearly nine times the capital sitting in Sei’s protocols.
From DragonSwap to Saphyre
Saphyre evolved from DragonSwap, an earlier exchange on the network, and has processed more than $6.6 billion in DEX volume on Sei over its lifetime. That means one venue and its predecessor account for more than 40% of all the trading volume Sei has ever recorded.
Sei passed $4 billion in cumulative DEX trading by early 2025, and the network logged multi-billion-dollar trading periods during that year. Getting from roughly $4 billion to $15.9 billion in under two years means the cumulative total has nearly quadrupled.
Background: a chain built for traders
Sei’s Pacific-1 mainnet went live in August 2023. The launch came alongside an airdrop of the SEI token, the network’s native asset, which handles transaction fees, network staking, and governance.
Sei Labs raised close to $35 million from investors including Multicoin Capital and Coinbase Ventures. The company was founded by Jayendra Jog, a former software engineer at Robinhood, and Jeff Feng, who has experience in investment banking at Goldman Sachs and venture investments at Coatue.
What this means for Sei and its users
The concentration is the obvious caveat. When one exchange processes about $276 million of $278 million in monthly volume, the network’s trading activity is effectively a bet on that single protocol continuing to operate smoothly.
At approximately $31.71 million, the TVL base is small relative to the volume running through it. Whether TVL grows alongside volume or stays flat is worth tracking.
The weekly uptick of 15.41% in daily volume is a modest positive signal. More trades mean more transaction fees paid in SEI, and a busier network gives stakers and governance participants more to oversee.

Sei Network (SEI) now supports tokenized funds from major asset managers including BlackRock, Apollo, Brevan Howard, Hamilton Lane and Nomura's Laser Digital, alongside Ondo Finance.
@SeiNetwork now supports tokenized institutional funds from a broad group of global asset managers, adding to the growing real-world asset (RWA) activity on the layer-1 blockchain. The offerings include products linked to @BlackRock, Apollo, Brevan Howard, Hamilton Lane, Nomura's @LaserDigital_, and @Ondo Finance.
The multi-issuer integration gives accredited investors and institutional desks onchain access to a range of fund strategies, including private credit and hedge fund exposure, on Sei's parallel execution layer.
How the funds reached SeiMuch of the rollout came in October 2025. According to crypto.news, tokenization platform KAIO launched BlackRock's ICS US Dollar Liquidity Fund and Brevan Howard's Master Fund on Sei, while Securitize also brought an Apollo fund to the network. The same report said investors can access shares of the BlackRock and Brevan Howard funds by holding a KAIO token on Sei.
Yahoo Finance reported that KAIO, backed by Brevan Howard and Nomura's crypto-focused Laser Digital, had issued more than $200 million in tokenized assets across feeder funds from Brevan Howard, Hamilton Lane, Laser Digital and BlackRock. The tokens are available to institutional and accredited investors and allow onchain subscription, redemption and reporting. The same report said Securitize's Apollo Diversified Credit Fund (ACRED) was a $112 million tokenized feeder fund of Apollo's private credit vehicle.
Hamilton Lane's Senior Credit Opportunities Fund (SCOPE) followed. Sei's own weekly roundup said it went live on the network via KAIO, after earlier launches from BlackRock, Brevan Howard and Apollo.
Why parallel execution mattersSei is a layer-1 chain built for trading and financial applications. According to CoinMarketCap, it uses optimistic parallelization, processing transactions across multiple cores at once rather than sequentially as Ethereum does, and targets block times of roughly 400 milliseconds. That design is central to Sei's pitch as a settlement layer for tokenized assets.
Tokenized funds still operate within existing legal, tax and compliance frameworks, even when the infrastructure is onchain. For institutions, the appeal is faster settlement and programmable access to products that were previously available only through traditional channels. $SEI is the network's native token.

SEI perpetual futures have been certified by a CFTC-regulated US exchange. The USD-settled contracts trade 24/7 with no expiry, while three SEI ETFs await SEC progress.
A CFTC-regulated exchange has certified $SEI perpetual futures, @SeiNetwork announced on October 16. The contracts settle in US dollars, trade around the clock and have no expiry date, placing SEI alongside BTC, ETH, SOL and XRP among assets with perpetual futures on CFTC-regulated venues.
What the filing shows The filing was submitted by North American Derivatives Exchange, which operates as OG.com Markets, and the exchange said it intended to list the contract by October 12. According to the exchange's certification document, the contract is settled in US dollars, has no expiration date and tracks the token's spot price through a reference index. The filing also specifies margin requirements and periodic funding adjustments meant to keep futures prices aligned with the underlying market.
Certification is different from a formal approval. Under CFTC rules, a designated contract market can list new products by self-certifying compliance with the Commodity Exchange Act, filing the product terms at least one business day before launch. Trading availability, liquidity and volumes for the SEI contract have not been confirmed, and the listing does not guarantee fresh demand for the token or sustained price gains.
The product adds a regulated route to SEI exposure without holding the token directly. It is designed to let traders take long or short positions without directly holding the token.
US perps market and SEI ETFsUS-regulated perpetuals are a recent development. On May 28, 2026, the CFTC approved the first perpetual futures contract cleared on a US-regulated exchange, a cash-settled Bitcoin perpetual listed by Kalshi. Perpetual futures have no expiration date and have become the dominant form of crypto derivatives trading globally, but were largely unavailable on regulated US exchanges.
On the ETF side, three SEI products from REX-Osprey, Canary Capital and 21Shares are still in the SEC process. REX Shares and Osprey Funds have set October 23 as the target effective date for their proposed fund, after filing a post-effective amendment on Sept. 24. The proposed REX-Osprey $SEI + Staking ETF would hold $SEI and stake part of its holdings through Sei Network's proof-of-stake system. 21Shares filed with the SEC to launch an ETF tracking the price of SEI, following Canary Capital's similar application in April 2025.
Together, a regulated derivatives product and pending exchange-traded funds would give US investors more compliant ways to gain exposure to SEI, though none of the ETFs has yet been confirmed as launched.

Where Hermes Fits in the Giga Roadmap Hermes is the consensus component planned for a later phase of that rollout. as distinct milestones still ahead.
One important caveat worth keeping in mind: Lab results and live network conditions rarely match exactly, so the figures are best read as a technical proof-of-concept rather than a live performance guarantee.
Still, the numbers set a clear marker.

@SeiNetwork has emerged as the dominant chain for @Ondo's flagship yield token, with more than 90% of $USDY's supply now sitting on Sei. According to a recent post from the Sei team, that concentration translates to roughly $259 million worth of the Treasury-backed token held on a single chain.
What Is USDY? The token is designed for non-U.S. individual and institutional investors, combining the accessibility of a stablecoin with the protections of traditional fixed-income products.
Why Sei?
That performance profile makes Sei a natural fit for capital that demands reliable, near-instant settlement.
That day-one DeFi composability has likely contributed to the rapid accumulation of supply on the chain.
The $259 million USDY concentration adds further weight to Sei's positioning as a settlement layer for real-world assets.

From Wall Street to the blockchainWhen Robinhood halted GameStop ($GME) trading at the height of the January 2021 short-squeeze frenzy, it exposed a fault line that two engineers could not ignore. @jeffdfeng (Jeff Feng), a former Goldman Sachs technology banker who later moved into venture investing at Coatue, and @jayendra_jog (Jay Jog), a former Robinhood software engineer, saw a centralised system buckle under pressure and decided to build something different.
The two co-founded @Sei_Labs in 2022, setting out to create trading infrastructure with no single point of failure. Most of the startup's early engineering team came from Robinhood's clearing team, bringing firsthand knowledge of exactly where centralised systems break down.
Market makers Flow Traders and Hudson River Trading backed the project, joining a $5 million seed round led by Multicoin Capital, with participation from Coinbase Ventures and GSR. The capital enabled @SeiNetwork to build out its mainnet, which launched in August 2023.
The Giga rebuild: chasing 200,000 TPSSei Labs is not standing still. The team is now rolling out Giga, an ambitious chain rebuild that targets 200,000 transactions per second with finality under 400 milliseconds. The upgrade is being delivered through three major components: Autobahn, Ares, and Eidos, each targeting a different part of Sei's infrastructure, covering consensus, transaction execution, and blockchain storage.
The project is targeting more than 200,000 TPS, compared with the network's previous throughput range of roughly 5,000 to 12,500 TPS. The storage (Eidos) and execution (Ares) engines are already live following the v6.6 mainnet upgrade in August 2026. The final component, Autobahn, will introduce a multi-proposer consensus design, replacing the single-proposer model to unlock foundational throughput gains, and its mainnet activation is the next major technical milestone.
Sei's internal testing has demonstrated more than 200,000 TPS under controlled conditions, though those results do not represent sustained mainnet performance. The gap between a controlled benchmark and real-world load remains the key variable to watch as the rollout continues.
What started as a reaction to a retail trading crisis has grown into a serious infrastructure play, with Sei Labs positioning $SEI as a high-throughput home for DeFi and on-chain trading applications.

A Remarkable Throughput Milestone@SeiNetwork has crossed 2.63 billion total transactions since its mainnet launch in mid-2023, a figure that puts the scalability-focused EVM blockchain in rare company across the entire crypto industry. To put that number in perspective, @Ethereum mainnet has processed roughly 3.75 billion transactions over more than 11 years of operation. Sei has come close to matching that figure in under three years.
The comparison is striking not because it diminishes Ethereum's standing as the dominant smart contract platform, but because it illustrates just how aggressively Sei has been built for throughput. Sei is a high-performance Layer 1 blockchain designed to achieve the speed and efficiency of centralized systems without sacrificing decentralization. Its architecture uses a parallel execution engine that allows multiple independent transactions to be processed simultaneously, supporting a theoretical maximum of 12,500 transactions per second on its current mainnet, with finality in under 400 milliseconds.
What Comes Next for SeiThe 2.63 billion transaction milestone arrives as Sei pushes toward an even more ambitious phase of its development. The Giga upgrade is Sei Network's major 2026 technical milestone, targeting over 200,000 transactions per second and sub-400 millisecond finality through a new Autobahn consensus mechanism and asynchronous parallel execution. The storage and execution engines are already live following the v6.6 mainnet upgrade in August 2026.
Sei has also committed to completing its transition to an EVM-only chain, deprecating its original CosmWasm smart contracts and native Cosmos transaction types through community vote SIP-3. The move is designed to consolidate development focus and lower the barrier for Ethereum developers looking to build on a faster execution environment.
The Sei Development Foundation has reported significant ecosystem metrics, including 85 million new wallets and over $250 billion in stablecoin transactions. With $SEI's throughput numbers now approaching those of chains with a decade-long head start, the network's case as a serious contender in the Layer 1 landscape is becoming harder to dismiss.

Donald Trump is willing to offer Iran sanctions relief in exchange for "substantive progress" on the nuclear issue.
According to Al Jazeera, U.S. President Donald Trump is open to considering easing sanctions on Iran and unfreezing Iranian funds if "specific progress" is made on the Iran nuclear issue. U.S. officials said the U.S. and Iran are holding "positive and constructive" discussions via intermediaries, but no deal will be reached if the nuclear issue is not resolved. The official added that Iran has signaled some flexibility on the nuclear issue, though the two sides have yet to agree on the timeline for implementing relevant commitments. Trump previously rejected Iran’s proposal to reopen the Strait of Hormuz, calling the plan "unacceptable." Trump said more talks with Iran are expected this week. Negotiations on the U.S. side are led by Middle East envoy Steve Witkoff, Jared Kushner, Vice President JD Vance, and Secretary of State Marco Rubio. U.S. Ambassador to the UN Mike Waltz said Trump is skeptical of Iran’s proposals, believing Iran is demanding all its conditions be met before advancing further negotiations. White House officials also noted the U.S. is cautious about Iran’s commitments, citing Iran’s violation of the U.S.-Iran memorandum of understanding reached in July, which included attacks on commercial vessels.

Crypto markets saw a short-term rally, as foreign media reported that Trump is prepared to ease sanctions on Iran.
According to Al Jazeera, U.S. officials said the U.S. is continuing active discussions with Iran via intermediary channels; no agreement will be reached unless the nuclear issue is resolved. Trump is prepared to ease sanctions on Iran and unfreeze its frozen assets in exchange for progress on the Iran nuclear issue. Possibly as a result, the crypto market rallied in the short term, while U.S. WTI and Brent crude oil prices dropped by roughly $1 each, hitting $92.02 per barrel and $105.65 per barrel respectively.

Analysis: The restaking 'gold rush' is ebbing, profits of Ethereum's leading protocols have shrunk sharply
As restaking yields continue to decline and smart contract risks rise, Ethereum’s leading liquid restaking protocol ether.fi is gradually exiting the restaking business and shifting to a "crypto neo-bank" model. Data shows that as of September 8, the restaking sector’s assets under management (AUM) stood at approximately $10.02 billion, generating only around $99,977 in fees over the past week. By contrast, liquid staking protocols manage roughly $51.87 billion in AUM and produced about $27.35 million in fees. Calculated per dollar of assets, fees from liquid staking are roughly 53 times higher than those from restaking. ether.fi CEO Mike Silagadze noted that restaking offers "no meaningful yield opportunities" while exposing users to additional risks, prompting the firm’s exit from the segment. As of August, less than 1% of ether.fi’s assets remained restaked via EigenLayer, with the company expected to fully sever related structural connections by the end of this year. Meanwhile, the five major liquid restaking protocols—Renzo, Kelp, Swell, Puffer Finance, and Bedrock—combined to generate around $953,000 in gross profit in Q2 2026, a sharp decline from the $2.18 million they earned over the prior three quarters. ether.fi has since pivoted its business focus to crypto neo-banking, including offerings such as crypto payment cards, lending markets, yield vaults, and tokenized stocks and metals.

Bonk Guy pumps MARSCOIN, claiming it could see 'explosive growth' in the fourth quarter.
Renowned crypto trader Bonk Guy has stated in a post that MarsCoin (MARSCOIN) features a "very clean" recent technical trend, indicating it could be primed for a significant rally in the fourth quarter. He noted that BNB and BNB Chain’s influence is growing in this cycle, while MarsCoin combines the "Elon Musk + CZ" concept alongside narratives like SPCX, with its fundamentals gradually taking shape. Bonk Guy also added that during the last cycle, he helped drive rallies for multiple Elon Musk-themed meme coins, with SHIB and DOGE once surpassing $40 billion and $80 billion in market cap respectively. He explained that this cycle, MarsCoin integrates Elon Musk, CZ and SPCX narratives, and Binance currently supports SPCX via its reward program, allocating a portion of trading fees to related incentives. As a result, the market may be underestimating MarsCoin’s future upside potential.

Manus 2.0 Officially Launched: New Architecture, Professional Studio Tool, and Personal AI Agent Application Cue Roll Out Simultaneously
Beating AI Express (Dongcha) – Manus has officially launched Version 2.0, a comprehensive upgrade rather than a simple iteration, centered on the question of "what the next-generation Manus should look like". Key upgrades include: its self-developed Agent framework Cascade, which tests show cuts token consumption by 23.2%, reduces task completion time by 28.2%, and lowers operating costs by 32%; a new cloud PC for dedicated environments such as game servers or long-term automation; event-triggered automation that enables workflows to start from changes in email, Slack, Notion, and more; a desktop app upgraded to Manus Studio, allowing on-demand integration of tools; and new offerings including a video editor (supporting timeline fine-tuning and Alchemy creative mode) and a game development environment (supporting real-time modification, one-click multiplayer online, and cloud PC hosting). The Computer Use capability has also been upgraded, letting users remotely control authorized computers via natural language. A new standalone app, Cue, has launched for personal Agents, supporting mobile and desktop. Each Agent comes with its own email, phone, wallet, and PC, can form multi-Agent teams for collaboration, and integrate with offline services. Manus noted that Version 2.0 focuses on refinement and control after idea implementation, continuing its core mission of "helping people turn ideas into reality".

An address linked to BlackRock withdrew approximately $127 million worth of BTC and ETH from Coinbase Prime.
According to monitoring by Onchain Lens, BlackRock’s address has cumulatively withdrawn approximately $126.95 million in crypto assets from Coinbase Prime over the past hour, including roughly $95.43 million in Bitcoin (BTC) and $31.52 million in Ethereum (ETH).
Sei’s tokenized-stock push gained momentum as the SEI token rallied 17.85%, with stronger market activity and expanding real-world asset exposure.
In particular, Dinari’s partnership with Sei introduced more than 700 tokenized U.S. stocks onto the network’s blockchain ecosystem.
This collaboration extended Sei’s exposure to the tokenized real-world assets and also introduced another potential source of network utility.
Alongside the price expansion, SEI’s trading volume also responded with a 128% increase to $193.6M over 24 hours, reflecting considerable market participation.
Ecosystem liquidity expands alongside activity Sei’s DeFi liquidity was reinforced as its Total Value Locked (TVL) expanded to $41.71 million following the recent price advance.
The TVL registered a notable increase of 6.62% within 24 hours, suggesting renewed capital deployment across applications running on the network.
Market positioning, however, revealed a more complicated outlook around SEI’s rapid price recovery.
Source: SEI TVL on DefiLlama Sellers persist despite exchange outflows According to CoinGlass, SEI had recorded $323.81K in spot net outflows at reporting time, continuing the broader exchange withdrawal pattern visible throughout the year.
These negative netflows implied that more tokens were leaving exchanges rather than entering during the 24-hour period.
Contrastingly, the taker activity suggested that sellers remained aggressive despite the declining exchange supply. Specifically, the Spot Taker CVD indicator remained seller-dominant, reflecting continued market selling.
Futures traders reflected similar positioning, with the Futures Taker CVD metric also remaining seller-dominant.
Source: Sei Spot Taker CVD on CryptoQuant Can SEI extend its structural breakout? On the weekly technical structure, SEI broke above its descending channel before clearing the $0.07670 resistance level. The breakout confirmed a bullish change of character after an extended period of a downtrend move.
The token then subsequently pushed towards the $0.08166 area, rapidly pushing away from its former channel resistance.
It is worth noting that the CHoCH marked a significant structural change after an extended period of declining prices. Notably, the weekly chart exposed the $0.12 price level as the next major zone of interest.
Source: SEI/USDT Weekly Chart on TradingView Ultimately, SEI’s breakout gained support from the growing ecosystem liquidity, tokenized-stock exposure, and reduced exchange supply.
However, seller-dominated taker activity remained the main counterweight, but if bulls defend the $0.07670 support, SEI could extend its price rally towards $0.12.
Final Summary Tokenized stocks and rising network liquidity have added fundamental backing to SEI’s recovery. SEI’s bullish CHoCH has shifted focus toward $0.12 after clearing its descending channel.
@Sei_Labs has published benchmark results for Hermes, the consensus protocol it plans to run on @SeiNetwork's Sei Giga. In a controlled test across 51 validators at 100,000 transactions per second, Hermes recorded a median finality of 68 milliseconds. Even when three block-proposing validators were stalled, the protocol finalized 95% of transactions within 206ms, finishing ahead of three rival designs in the team's own internal comparison.
What Hermes Is Built to Solve Fault tolerance is the central problem Hermes is designed to address. Most consensus protocols slow down or stall when validators go offline. The Hermes results suggest the protocol can absorb validator failures without a significant collapse in confirmation speed, which matters most in high-stakes trading environments where every millisecond counts.
Hermes sits within a broader, multi-phase engineering program Sei Labs calls Sei Giga. Sei Giga is not a single upgrade; it is a multi-phase engineering program that rebuilds Sei's execution client, storage layer, and consensus mechanism from scratch. The design goal is to allow for efficient, fast, and fair on-chain trading, which requires very high throughput, low latency, and the ability to bound censorship and MEV risk.
Where Hermes Fits on the Roadmap Hermes is a later-stage addition to the Giga stack. The current roadmap calls for deploying a testnet for Hermes consensus before merging it into Sei mainnet. The protocol's full whitepaper has not yet been published. Hermes is listed as a next-generation consensus protocol on the official roadmap, with its whitepaper still pending.
The Giga program has already set ambitious top-level targets. The layer-1 blockchain is targeting over 200,000 transactions per second and sub-400 millisecond finality, numbers that would make it one of the fastest EVM-compatible chains in existence. Sei's updated Giga Whitepaper v2 reduced the targeted finality to below 250 milliseconds, down from the previously stated 400 milliseconds. The 68ms figure from the Hermes lab results, if it holds in a live environment, would represent a meaningful step beyond even those revised targets.
As with any benchmark published by the team developing the protocol, the results carry caveats. Real-world mainnet performance after any upgrade may differ from devnet benchmarks. Live networks carry economic activity, validator diversity, and unpredictable transaction patterns. Sei Labs has not yet set a hard launch date for Hermes on mainnet.

Canary Capital Revises Staking Structure in Latest SEI ETF AmendmentCanary Capital has submitted a significant update to its proposed Staked $SEI ETF, filing Pre-Effective Amendment No. 2 to its S-1 registration statement with the U.S. Securities and Exchange Commission.
This marks a notable shift from the original filing, which The revised structure consolidates all custody with BitGo and introduces a more defined staking allocation.
Market Reaction and Broader Context
A staked SEI ETF would add a third network to that roster.
Canary Staked SEI ETF, Pre-Effective Amendment No. 2 to Form S-1, SEC EDGAR | Canary Capital Moves Closer to SEI Staking ETF With 90% Stake Plan, CoinCodex | Canary Capital Updates Staked SEI ETF Filing With S-1 Amendment, Tron Weekly
Sei’s breakout is accelerating after weeks of failed attempts near $0.052. This suggests a shift from a consolidation phase to an upward momentum.
After weeks trading below the $0.052 resistance, buyers pushed the price of the token to $0.06285. In turn, the token gained over 25% in 24 hours. Daily volume surged alongside the price to $203.44 million, a 289% spike according to CoinMarketCap data.
This suggested broader market participation behind the move rather than just speculation.
However, the breakout price has risen well beyond the prior trading range. Therefore, this leaves very little support for Sei [SEI] above $0.052. The RSI stood at 87.64, which also reinforced the imbalance, indicating that momentum has reached extreme levels.
Source: TradingView Ultimately, even though the overall trend of Sei’s breakout remains bullish, buyers may find it difficult to sustain their recent gains. A hold at $0.052 will continue to validate the construction of the trendline, but another drop could put pressure on demand to absorb selling pressure.
Canary’s ETF targets SEI staking SEI’s sharp breakout is now being reinforced by a proposed ETF structure that could change how new demand affects supply. Canary Capital’s amended S-1 proposes staking roughly 90% of the ETF’s SEI holdings.
This could lead to the majority of tokens acquired through purchases being removed from open circulation. Currently there are approximately 4.2 billion tokens out of the total of 10 billion tokens, or approximately 42% of the circulating supply, that are already staked.
Source: X Hence, the ETF will also limit an already small number of available and tradable tokens rather than open up new avenues. Additionally, all future staking reward payments will go directly into the fund, thereby increasing the yield invested in SEI directly.
Moreover, BitGo will serve as the sole custodian, simplifying operations while concentrating custody exposure. Larger inflows could tighten liquidity further and amplify SEI’s response to demand.
Can the ETF narrative sustain SEI momentum? While ETF headlines have fueled sentiment, derivatives markets continue to drive a significant portion of current activity. Open Interest (OI) sits near $95 million, while funding remains moderately positive around 0.01%.
Source: CoinGlass Thus, as the OI and funding levels suggest, traders are positioning for further gains, yet derivatives could also amplify a reversal. More importantly, the proposed ETF has not started attracting actual creations because approval and listing remain pending.
In other words, the recent increase in premium continues to rely on expectations for the proposed ETF rather than direct ETF demand. A stronger shift toward spot trading would give the rally a firmer base.
Consequently, without it, fading ETF optimism could encourage leveraged traders to exit, putting recent gains under pressure.
SIP-3 and Eidos Go Live as Giga Rollout Begins@SeiNetwork is accelerating the rollout of its most ambitious technical overhaul to date. The Sei Giga upgrade, designed to push the network toward 200,000 transactions per second (TPS) with sub-400ms finality, is now moving from blueprint to live deployment.
According to Sei Labs, the v6.6 mainnet upgrade officially deployed the first two architectural pillars of the Giga plan: the Ares execution engine and the Eidos storage engine. Ares becomes the default execution path on upgraded validator nodes, replacing the legacy Go-native v2 engine with an EVMC-backed framework to reduce contract processing times and eliminate internal bottlenecks. Eidos, meanwhile, separates EVM state history from Cosmos state into a dedicated database, removing the storage constraints that would otherwise prevent the execution layer from operating at Giga-level speeds.
SIP-3, the governance-approved proposal to transition Sei from a dual Cosmos and EVM stack to a fully EVM-only chain, is running in parallel. Sei Labs describes SIP-3 as the weight-reduction phase of the upgrade, stripping hundreds of thousands of lines of Cosmos and CosmWasm code from the protocol to allow the network to scale more efficiently.
Autobahn Consensus Remains the Final MilestoneThe Giga upgrade is structured around three distinct layers: storage (Eidos), execution (Ares), and consensus (Autobahn). With Ares and Eidos now active on mainnet, Autobahn remains the largest component still ahead. Autobahn introduces a multi-proposer consensus design that allows several validators to propose blocks simultaneously, replacing the single-proposer model and unlocking the throughput gains that Giga promises at a foundational level.
The phased approach means the network remains live throughout the transition. Sei Labs confirmed that the Eidos migration runs alongside existing storage systems with no downtime required, and the Ares rollback mechanism allows individual transactions to revert to the legacy engine if edge cases arise, ensuring continuity without compromising block production.
Together, these upgrades represent a comprehensive architectural shift rather than an incremental performance tweak. The network previously supported a throughput range of roughly 5,000 to 12,500 TPS. The Giga target of 200,000 TPS represents a step-change in capacity aimed at supporting high-frequency trading, autonomous application deployment, and on-chain activity at institutional scale.

Engineering Talent Moves In-House@Sei_Labs has acquired @bilinearlabs, bringing the firm's Rust-based engineering talent and data analytics capabilities directly into the $SEI ecosystem. The Bilinear team is transitioning into core development roles focused on Sei Network and the upcoming Sei Giga scaling initiative, deepening the in-house technical bench at a critical moment for the protocol.
The move follows Bilinear's track record of delivering real-time financial insights and on-chain intelligence for high-velocity decentralized markets, a profile that fits squarely with Sei's performance-first positioning in DeFi infrastructure.
What Is Sei Giga and Why Does It Matter?Sei Giga is @Sei_Labs' most ambitious technical undertaking to date. The initiative targets over 50x throughput, 70x faster block production, and 40x execution efficiency, with the broader goal of making Sei the first multi-proposer EVM Layer 1. It leverages parallel block proposals to solve bottlenecks, scaling the EVM with innovations across data availability, consensus, execution, and storage.
Key targets include 5 gigagas of throughput at roughly 200,000 transactions per second, alongside sub-400ms finality for low-latency, high-speed applications. Achieving that throughput would deliver execution speeds 50 times faster than any other mainnet chain, comparable to Web2-level transaction performance.
Advanced features including Autobahn consensus, a multi-proposer architecture, and the 5 gigagas throughput target are currently in development. Sei Labs has already achieved 5 gigagas of throughput in an internal devnet using Autobahn, a new consensus protocol designed for high throughput and low latency in globally distributed validator networks.
Bringing Bilinear's engineering resources in-house signals that Sei Labs is consolidating specialist talent rather than relying on external contributors as Giga moves closer to production. For the $SEI ecosystem, the acquisition adds depth on the data and systems side at a point when the protocol's technical roadmap is at its most complex.

FlatKV Clears 200,000 TPS in Internal Testing@Sei_Labs has published benchmark results showing its new FlatKV storage engine averaged 205,913 transactions per second across a 24-hour test window. That figure stands 13.7 times above the roughly 15,000 TPS recorded by @SeiNetwork's current MemIAVL store under the same conditions, according to the team.
FlatKV is part of Eidos, the storage component of Sei's broader Giga upgrade program. Eidos is set to replace the existing structure for EVM state with FlatKV, a flat key-value storage system where an individual state change requires a single write. Verification will be handled using LtHash, or lattice hashing, which maintains a running fingerprint of the state. Under the design described by Sei, LtHash can update that fingerprint in constant time when state changes, removing the need to recalculate a path of hashes through a Merkle tree.
Where Giga Stands on Mainnet The first phase of Eidos reached Sei mainnet with the v6.6 release in August 2026, with EVM state beginning to move into its own dedicated database. That initial release also shipped a rebuilt pruning path, reducing a cleanup pass that used to take 8 to 18 minutes down to about five, and keeping nodes within 60 blocks of the chain tip.
The larger components of Eidos, including FlatKV with its lattice hash, the LittDB-backed receipt store, and the off-node archive, will arrive in subsequent releases. @Sei_Labs has the new store slated for a later release, where it replaces the Merkle tree for EVM state.
The upgrade is the storage component of a three-part architecture overhaul that also includes Autobahn for consensus and Ares for transaction execution. Sei Labs released its Giga whitepaper with a design targeting 200,000 transactions per second, 5 gigagas of throughput, and finality below 400 milliseconds. The migration is designed to run while Sei remains online, with existing and new storage systems operating alongside each other.
Sei's internal testing has demonstrated more than 200,000 TPS under controlled conditions, though those results do not represent sustained mainnet performance. The FlatKV benchmark adds further weight to the storage case, but the full Giga stack, including the Autobahn consensus layer, has yet to reach mainnet.

From Pilot to Production@Mastercard and @SeiNetwork have published a joint report titled "The Foundations of Institutional Blockchain," offering a practical framework for banks and asset managers looking to move blockchain technology from experimental pilot programmes into full production. The report draws on over 40 interviews with senior figures across financial services and arrives at a clear central finding: technology is no longer the obstacle to institutional adoption.
The numbers behind that conclusion are striking. Large blockchain networks now process around 3,400 transactions per second, roughly 100 times the throughput recorded in 2019. Approximately $27 billion worth of bonds, funds, deposits, and other assets have already been tokenized, reflecting how quickly real-world asset infrastructure has matured.
Mastercard's Crypto Partner Program is an industry collaboration platform that connects select blockchain and digital asset firms with the company's payment infrastructure. For Sei, this means access to Mastercard's network of financial institutions, technology partners, and regulatory expertise, with the goal of exploring how Sei's high-speed blockchain can support payment flows, cross-border remittances, and settlement systems that meet traditional financial standards.
BlackRock Sets the BenchmarkThe report points to @BlackRock's tokenized treasury fund as a bellwether for institutional appetite. The fund crossed $2.5 billion in assets under management in May, underlining that demand for on-chain financial products is no longer hypothetical. BlackRock's USD Institutional Digital Liquidity Fund (BUIDL), a tokenized money market fund launched in March 2024 with Securitize as transfer agent, held approximately $2.5 billion in assets under management across six chains as of May 2026, making it one of the two largest tokenized US Treasury products in the market.
Several globally systemically important banks have already piloted tokenized commercial paper and short-term repo facilities. McKinsey and Company projected in June 2024 that the market capitalization of tokenized real-world assets could reach approximately $2 trillion by 2030.
The Mastercard and Sei report is positioned as a practical playbook for financial institutions evaluating blockchain infrastructure, offering decision-making criteria grounded in live market data rather than theoretical projections. For an industry that has spent years circling blockchain pilots, the message is straightforward: the infrastructure is ready, and the question is now one of execution.

DEX Volume Surges More Than 4x in a Single Day@SeiNetwork posted one of its sharpest single-day volume moves in recent memory on August 19, with on-chain DEX volume jumping from $3.9M to $16.24M, a rise of 316.57%. Crucially, this was not a low-base distortion: trading activity was already meaningful on August 18, making the scale of the move harder to dismiss as noise.
$SEI has also responded on the price side, gaining around 7% in the 24 hours to August 20 to trade at approximately $0.0418. The live Sei price today sits at roughly $0.041 with a 24-hour trading volume of over $31 million, according to CoinMarketCap.
The shorter-term trend in DEX activity is turning constructive. While volume is still down 11.07% over the past 30 days, it has recovered 5.27% in the last seven days, pointing to a short-term breakout rather than a sustained structural recovery. User activity has also picked up, with active users spiking to 3,111 on August 14.
Context: A Network Working Through a Difficult YearThe August bounce comes against a backdrop of broader network challenges in 2026. On-chain analysis of Sei Network this year has revealed a severe decline in user engagement across core metrics, with daily active addresses falling from a peak of nearly 2 million in March 2026 to fewer than 5,000 by late June. Daily transactions cascaded from 3 million to under 25,000 over the same period, pulling throughput from a February high of 38 transactions per second down to just 1 TPS in June.
However, the network is not standing still on the technical side. Sei is currently undergoing its most ambitious overhaul yet with the Sei Giga upgrade, which aims to support over 200,000 transactions per second with sub-400ms finality through a new consensus mechanism called Autobahn. Sei is also transitioning to a fully EVM-only environment in 2026 via the SIP-3 upgrade, using a parallel execution engine that processes multiple independent transactions simultaneously.
Sei was originally designed to enhance the functionality and performance of decentralized exchanges, and is recognized as the first sector-specific Layer 1 blockchain focused on optimizing trading processes. Whether this week's volume burst marks the beginning of a broader re-engagement or a temporary spike remains to be seen, but it gives the network a rare positive data point in an otherwise difficult stretch.

Sei has begun rolling out its Eidos storage upgrade, rebuilding how the layer-1 network stores and verifies on-chain data as its Giga roadmap targets throughput of 200,000 transactions per second.
Summary
Sei has begun the phased rollout of Eidos through its v6.6 mainnet upgrade. Eidos is rebuilding the network’s storage architecture as Giga targets 200,000 TPS. EVM state is being separated into a dedicated database, while FlatKV and LtHash are planned for later stages. The migration is designed to run while Sei remains online, with existing and new storage systems operating alongside each other. Sei said in an Aug. 12 technical update that Eidos is designed to remove storage constraints that could prevent the network’s execution layer from operating at the speeds planned under Giga. The upgrade is the storage component of a three-part architecture overhaul that also includes Autobahn for consensus and Ares for transaction execution.
The first Eidos components have already reached mainnet through Sei v6.6, though the full storage system is being introduced in stages. EVM state has started moving into a dedicated database, while FlatKV, LtHash, new receipt storage and off-node archival systems are scheduled for subsequent releases.
Sei Eidos upgrade changes how state is stored At the center of Eidos is a change to the way Sei plans to maintain and verify Ethereum Virtual Machine state.
Sei said traditional Merkle trees require nodes to recalculate multiple hashes when a value changes because each update alters the chain of hashes leading to the tree’s root. As the amount of stored data increases, individual state changes can therefore require additional database work.
Eidos is set to replace that structure for EVM state with FlatKV, a flat key-value storage system where an individual state change requires a single write. Verification will be handled using LtHash, or lattice hashing, which maintains a running fingerprint of the state.
Under the design described by Sei, LtHash can update that fingerprint in constant time when state changes. Instead of recalculating a path of hashes through a Merkle tree, a node removes the contribution of the old value and adds the new one, leaving the amount of work per update unchanged as the state expands.
The technical change is tied directly to the performance targets outlined for Giga. As crypto.news reported in May 2025, Sei Labs released its Giga whitepaper with a design targeting 200,000 transactions per second, 5 gigagas of throughput and finality below 400 milliseconds.
At that throughput, Sei said the network would also have to write hundreds of thousands of database entries every second. Faster transaction execution would therefore provide limited benefit if the storage layer could not process state changes and transaction history at a comparable rate.
EVM data is moving into a separate database Another part of Eidos separates EVM state from other data handled by Sei nodes.
Before the change, Sei said EVM state shared a database with other information on the chain. The new architecture gives EVM state its own dedicated store, preventing historical queries from competing directly with live transaction processing and reducing database work imposed on non-EVM modules.
The split started reaching mainnet in the v6.6 release during August. Sei also introduced a rebuilt pruning path for removing data that nodes no longer need to keep in active storage.
According to the network, the pruning changes reduced one cleanup process from between eight and 18 minutes to roughly five minutes during testing and operation. Nodes that could previously fall hundreds of blocks behind the chain tip remained within about 60 blocks after the change, Sei said.
Blocks and transaction receipts are also being assigned a separate storage engine called LittDB. Sei described blocks and receipts as data that is written once, repeatedly read, and eventually archived, making their storage requirements different from frequently updated account and contract state.
Internal benchmarks cited by Sei put LittDB write throughput above one gigabyte per second while handling about 55,000 point reads per second. A new receipt store sustained more than 150,000 writes per second during multi-hour benchmark tests that included garbage collection. Sei cautioned that the figure measures the storage engine and should not be treated as blockchain transaction throughput.
Older history will move away from active nodes Eidos also changes how much historical information individual nodes are expected to keep locally.
Sei said frequently accessed state and recent chain history will remain on fast local storage, while older historical records will move to archival systems built for capacity. Explorers, indexers and users auditing historical transactions will still be able to retrieve the archived information, according to the network.
Reducing the amount of old data kept on active nodes is intended to prevent historical queries from consuming resources needed for current transactions. Sei said rising storage requirements can otherwise force operators to use faster and more expensive hardware as network throughput increases.
The infrastructure work follows earlier efforts to increase access to Sei’s EVM ecosystem. MetaMask added native Sei support in August 2025, allowing users to access Sei-based applications, swap assets and bridge tokens directly through the wallet. At the time, Sei was processing more than 4.2 million daily transactions and had more than 11 million monthly active users, according to figures cited in the report.
A separate distribution agreement announced in December 2025 called for Xiaomi to pre-install a Sei wallet on new smartphones sold outside mainland China and the United States. The companies also planned support for stablecoin payments using assets such as USDC, with initial payment deployments planned for Hong Kong and the European Union.
Eidos migration runs while Sei remains online For node operators, Sei is carrying out the storage migration without stopping the blockchain.
The network said existing and replacement storage systems will operate alongside one another while data moves in batches from block to block. The rollout is controlled through governance and has been designed with a rollback process if problems emerge.
Ahead of deployment, shadow nodes replayed mainnet traffic against the new storage systems while integrity hashes were continuously checked, according to Sei. Testing showed block times remained largely unchanged while migration processes operated in the background.
Eidos is the third storage rebuild undertaken by Sei. The network previously replaced its original Cosmos storage architecture with SeiDB, followed by the state-store separation now being introduced on mainnet. FlatKV, LittDB and the off-node archival system will form the next stage as they arrive through later releases.
Users and application developers do not need to take action during the migration, according to Sei, with balances, smart contracts, historical records and existing RPC endpoints remaining available. Node operators have been given a migration guide covering configuration flags and the documented rollback process for the new storage system.
Sei Network's Giga upgrade is not a single software patch. It is a full architectural overhaul of three core parts of the blockchain: consensus, execution and storage, each rebuilt in parallel with the network continuing to run.
Three Tracks, One Goal Giga is structured around three upgrade tracks. The first is consensus, where a protocol called Autobahn replaces the single-proposer model.
The second track is execution, handled by the Ares upgrade.
The third track is storage, which is where Eidos comes in. Every transaction processed by a blockchain must be recorded. If the database cannot write data as fast as the network executes transactions, raw throughput gains become meaningless.
Why Storage Is the Hard Part
Eidos also separates live EVM state from other blockchain data entirely. Separately, LittDB-backed storage handles blocks and receipts. These records are written once but queried repeatedly, making them a distinct workload from constantly changing chain state. Older historical data will eventually migrate off active nodes into archival storage.
Crucially, the migration itself is designed to avoid downtime. Instead of halting the network and replacing the entire database at once, Eidos is built to migrate storage while Sei continues producing blocks, with the old and new systems running side by side, data moved in batches and integrity checks run throughout.
The pruning fix that shipped alongside Eidos is already measurable for operators, reducing a cleanup pass that used to take 8 to 18 minutes down to about five, and keeping nodes within 60 blocks of the chain tip where they used to drift hundreds behind.
The larger parts of Eidos, including FlatKV with its lattice hash, the LittDB-backed receipt store and off-node archival storage, will arrive in subsequent releases.
Reaching that speed requires more than a faster transaction engine. It requires a storage system capable of keeping up. That is what Eidos is trying to build.

Crypto Briefing: Sei unveils Giga upgrade roadmap
TL;DR: Every blockchain node has two jobs: compute what happens next on the chain, and store what has already happened. Storage is a critical bottleneck for all blockchains as they attempt to scale. If storage can't keep pace with the rate at which new transactions are executing, huge problems can occur. Eidos is the upgrade that will take Sei’s storage layer to Giga speed.
What is Sei's Giga Upgrade?Giga is the series of upgrades designed to dramatically improve the Sei blockchain, making it much faster and giving it next-generation features, to make it the optimal onchain environment for trading.
Giga is composed of three tracks of upgrades, one for each layer of the chain. A series of consensus upgrades, beginning with Autobahn, will rebuild how validators agree on what’s true. The Ares Upgrade rebuilds execution, the part that actually runs transactions. Eidos rebuilds storage, the critical part of the chain that stores all the transactions that have happened and allows users and apps to query this data.
Every transaction that a blockchain executes has to be written down, and if the notebook can’t keep up with the pen, the pen’s speed is irrelevant. A chain that executes at 5 gigagas per second while writing to a database designed for an earlier era is a sports car on bicycle wheels.
Eidos exists to fix that. It introduces a new database structure, and implements it onto the chain live, while the blockchain keeps running.
Understanding blockchain storageA blockchain stores multiple things. First, the live state of the network: every account balance, every deployed contract, every value those contracts keep in their storage. Secondly, the historical state: every block ever produced, every transaction inside those blocks, and every receipt recording what each transaction did.
This storage is essential for every aspect of using a blockchain. When you check a balance in your wallet, a node looks it up in state. When a trading app draws a price chart or a block explorer shows last week’s transfers, nodes are reading history.
Each transaction changes some state and appends to history, so a chain processing 200,000 transactions per second is also writing hundreds of thousands of database entries per second, every second, forever.
When a blockchain’s storage can’t keep pace with execution, often the only way to survive is to throw money at the problem. Larger, faster, and more expensive disks can compensate for a slow data layer. But as throughput grows and hardware requirements rise, the cost of running a node swells until most operators can’t afford to run them. Queries about last month slow down the processing of live transactions. Eventually the execution layer, however fast, sits idle waiting for the database to catch up.
Why Sei Giga needs better data validationA blockchain database can’t just store data; it has to be able to verify the data hasn’t been tampered with. The classic tool for this is a Merkle tree: every piece of state gets hashed, hashes get paired and hashed again, and again, until a single root hash fingerprints the entire state of the chain. Anyone can check a value against that root and know it’s genuine.
Because the values are chained together in a tree, updating one account means recomputing every hash on the path from that account up to the root, and each of those recomputations is another disk write. Even worse, the more data stored by the chain, the more expensive each individual update becomes. Because of this, at 200,000 TPS, Merkle trees stop being feasible.
Eidos retires the Merkle tree for Sei’s EVM state. Its replacement, a store called FlatKV, keeps state in a flat key-value layout where one change is one write. A lattice hash (LtHash) maintains a running fingerprint of the entire state that updates in constant time per change, without cascading recomputation. The network keeps its ability to verify everything.
Instead of arranging every value in a tree and hashing a path to the top, the node keeps one fingerprint that individual changes can be added to or subtracted from directly. Update a balance and the node subtracts the old value’s contribution and adds the new one, a fixed amount of work no matter how large the state grows.
What else changes under the hoodRemoving the Merkle tree is the core architectural move, but Eidos is a rebuild of the whole storage stack.
Live state gets its own databaseToday, EVM state shares a single database with everything else on the chain. Under Eidos it moves into its own dedicated store. Reads of history stop competing with live transaction processing, and the chain’s non-EVM modules stop paying write costs for EVM data they never touch. The EVM state split began rolling out in v6.6.
Each workload gets the right engineEvery transaction onchain produces a receipt: a record of what happened, what it cost, and which events it emitted. Each time a wallet shows the confirmation checkmark, an app verifies your swap landed, or a dashboard tallies yesterday’s volume, something is reading receipts. At Giga’s target throughput, Sei would produce 200,000 of them per second.
Blocks and receipts have a peculiar shape as data: written once, never updated, read constantly, and eventually archived. Sei’s new block and receipt stores run on LittDB, an open-source embedded database originally developed by a Sei Labs engineer for exactly this write-once pattern, now integrated into Sei’s node software. LittDB has been clocked at over a gigabyte per second of write throughput while serving roughly 55,000 point reads per second at the same time, and the new receipt store sustained more than 150,000 writes per second, flat, across multi-hour benchmark runs that included garbage collection. That number is a benchmark of the storage engine itself, not a chain TPS figure, so it isn’t comparable to Giga’s 200,000 TPS target.
Old history leaves the nodeWhile the state and recent history a node actually touches stay local, on the fastest storage, older history moves off the node entirely, into archival storage built for capacity rather than speed. Full history stays available to anyone who asks: explorers, indexers, and anyone auditing the chain’s past read from the archive, while the nodes doing real-time work carry only what real-time work needs.
Upgrading storage while the chain stays liveSei already has a live database which holds the entire live state of the network, and the chain on top of it produces a block roughly every 400 milliseconds, around the clock.
The easiest option would be to halt the chain, snapshot everything, migrate, and relaunch. Or ask every node operator to throw away their data and rebuild from scratch. Both approaches are common, and respected networks have used them.
Eidos takes the harder route: the migration runs inside the node while the chain keeps producing blocks. Data moves across in small batches, block by block, with the old and new stores running side by side until the new one has proven itself, and the whole rollout is switched on by governance and reversible by design. It’s also checked at every step: shadow nodes replayed real mainnet traffic against the new stores before rollout, integrity hashes are audited continuously, and in testing, block times stayed essentially unchanged while the migration ran underneath.
The first phase of Eidos reached Sei mainnet with the v6.6 release in August 2026. EVM state began moving into its own database, and a rebuilt pruning path shipped alongside it. That pruning fix is already measurable for operators, reducing a cleanup pass that used to take 8 to 18 minutes down to about five, and keeping nodes within 60 blocks of the chain tip where they used to drift hundreds behind. The larger parts of the Eidos upgrade, such as FlatKV with its lattice hash, the LittDB-backed receipt store, the off-node archive, will arrive in subsequent releases.
What users need to knowUsers and app developers don't have to take any actions. Balances, contracts, and history carry over untouched. Existing RPC endpoints can be used as normal.
If you run a node, the migration guide for RPC operators is already public in the sei-chain repository, with the config flags and the rollback path documented. Longer-term, node operators will be able to run leaner machines. This has long term benefits for the chain, as it will become cheaper to become a Sei node operator.
The third rebuildEidos is the third time Sei has rebuilt its storage layer, and every rebuild has shipped into a network that was already live. SeiDB replaced the original Cosmos storage stack. The state-store split now on mainnet carved EVM data out into its own database. FlatKV, LittDB, and the off-node archive are the third generation, arriving phase by phase.
Giga’s target is 200,000 transactions per second. Eidos will make sure that Sei's storage smoothly keeps pace.

Round-the-Clock Equity Data Comes to Sei@Chainlink U.S. Equities Streams are now live on @SeiNetwork, delivering institutional-grade price data for the $80 trillion global stock market to a blockchain environment that never closes. Chainlink Data Streams has been integrated into Sei Network as its preferred oracle solution, bringing low-latency, high-frequency market data to power real-time DeFi and trading applications.
The practical effect is significant. Decentralized venues on Sei can now bypass the opening and closing hours of legacy exchanges, settling tokenized equity positions around the clock with sub-second finality. Sei, a layer-1 blockchain featuring EVM compatibility and parallelized execution, will use Chainlink Data Streams for sub-second price latency, high data accuracy, and liquidity-weighted bid-ask spreads.
Chainlink has launched Data Streams for major U.S. equities and ETFs including SPY, CRCL, QQQ, NVDA, AAPL, and MSFT, with additional markets and asset classes on the horizon. The infrastructure has helped enable more than $25 trillion in on-chain transaction volume for leading DeFi applications.
Monaco Trading Builds High-Frequency Equity Markets on $SEI@MonacoTrading is among the first protocols to put these $LINK-powered streams to work, using them to build high-frequency markets for primary stock tickers directly on the $SEI execution layer. Monaco is the high-frequency trading layer designed to establish a decentralized Wall Street on the Sei network. The protocol achieves microsecond execution coupled with Sei's 400-millisecond settlement, a 200,000x improvement over traditional T+1 settlement cycles.
Chainlink U.S. Equities Streams are already being leveraged by other top protocols, including Lighter, BitMEX, ApeX, HelloTrade, Decibel, Opinion Labs, and Orderly Network. The arrival of the streams on Sei broadens that ecosystem further, giving builders on the network access to the same pricing infrastructure used by established derivatives venues.
Chainlink's recent partnership with the U.S. Department of Commerce will also bring Bureau of Economic Analysis data on-chain to Sei Network, including Real GDP, PCE Price Index, and domestic purchasing metrics. That layer of macroeconomic data, combined with live equity feeds, positions Sei as one of the more comprehensively wired blockchains for finance-focused applications.

Sei (@SeiNetwork) v6.6 is live as of block 224,201,091, making it the network's largest upgrade since EVM support launched in May 2024. The release bundles nearly 400 pull requests and, more significantly, marks the first time Sei Giga components have touched mainnet.
Ares and Eidos: The First Giga Components Go Live The two headline changes in v6.6 each target a different layer of the stack. The release introduces the first pieces of two of the three major Giga upgrades: Eidos, a new storage layer that will begin moving the chain's history into its own database, and Ares, a rebuilt execution engine that will become the default path for running transactions.
Ares is now the default execution path on every upgraded node, and according to @Sei_Labs it delivers roughly 10x the throughput of the previous setup. With v6.6, Giga stops being a roadmap and starts being something running on mainnet: Eidos has begun moving history into storage built for scale, and Ares is now the default execution path.
The Eidos change addresses a structural inefficiency that has been present since EVM support arrived. Until now, Sei's EVM history and Cosmos state have shared the same database, meaning history reads compete with live activity and modules unrelated to the EVM still pay write costs for EVM data. Eidos separates them. EVM history will move into its own dedicated database, so reading old history stops competing with transactions happening in real time.
Security Patches and Validator Improvements Beyond the Giga components, v6.6 patches more than 30 security issues spanning denial-of-service exposure and supply-chain hardening. Validator operations also get practical improvements, including faster pruning and retuned consensus timing to smooth out day-to-day operations.
Both Ares and Eidos are only the first step and will continue across future releases. v6.6 is a large release, with many fixes unrelated to Sei Giga. The third pillar of the Giga programme, a new Autobahn consensus mechanism, is not included in this release. Consensus, the third major part of the Giga upgrade, will only go live later.
The longer-term ambitions remain substantial. The full Giga upgrade targets over 200,000 transactions per second and sub-400 millisecond finality through the new Autobahn consensus mechanism and asynchronous parallel execution. Those figures remain forward-looking benchmarks rather than live metrics, but v6.6 represents the first concrete step toward them on a live network.
$SEI holders have been following Giga's progress since it was first outlined in late 2024, and the mainnet rollout is now underway in earnest.

Sei Network Prepares to Launch Tokenized U.S. Equity Trading@SeiNetwork is gearing up to integrate @DinariGlobal, a move that would bring the first self-custodial U.S. equity portfolio to the high-speed Layer 1 blockchain. The upcoming launch is set to give investors access to 724 tokenized stocks, including every company in the S&P 500, settled directly in @Circle's $USDC.
Dinari's dShares platform enables tokenized U.S. stocks and ETFs that preserve the rights and protections of traditional securities, including guaranteed redemption at the National Best Bid and Offer, cash dividends, and automated corporate actions. As an SEC-registered transfer agent, Dinari has built infrastructure that enables broker-dealers, exchanges, fintechs, and other regulated financial institutions to issue, custody, trade, and service tokenized securities within the existing regulatory framework.
The integration bridges what proponents describe as the $75 trillion U.S. stock market with Sei's high-performance infrastructure. Sei offers sub-400ms finality, a parallelized EVM, and a modular architecture that supports continuous optimization. That speed makes T+0 settlement and 24/7 liquidity operationally viable for both domestic and international participants, something traditional equity markets, which close on weekends and settle on a T+1 cycle, have long been unable to offer.
A Broader Push to Put U.S. Equities OnchainThe Sei integration is part of a broader expansion by Dinari across multiple blockchain environments. Bitcoin.com announced a partnership with Dinari in May 2026 to offer tokenized U.S. equities to its ecosystem, giving users of the Bitcoin.com Wallet access to over 300 tokenized U.S. equities and ETFs. Dinari and tZERO also joined forces to create a turnkey platform for tokenized U.S. equities for broker-dealers, packaging issuance, trading, custody, settlement, and shareholder servicing into one regulated framework.
On August 4, 2026, Dinari announced the expansion of its U.S. operations to financial institutions via its broker-dealer subsidiary Dinari Securities LLC, allowing broker-dealers, banks, fintechs, and wealth platforms to offer tokenized securities products and services to both retail and institutional customers.
The regulatory backdrop is also shifting in Dinari's favor. Dinari recently joined the Blockchain Association, the leading trade association representing the digital asset industry in Washington, D.C., to contribute its expertise as policymakers continue shaping the future of tokenized securities. The Sei Network integration, once live, would represent one of the most direct on-ramps yet for crypto-native investors seeking exposure to mainstream U.S. equities without leaving self-custody.

TL;DR: the proposal for Sei 6.6 is live, and it will be the release where Sei Giga starts touching mainnet. 6.6 will introduce the first pieces of two of the three major Giga upgrades: Eidos, a new storage layer that will begin moving the chain’s history into its own database, and Ares, a rebuilt execution engine that will become the default path for running transactions.
What the two upgrades actually areA blockchain has three key components. It agrees on the order of transactions (consensus), it runs them (execution), and it keeps a permanent record of everything it has ever done (storage). Sei 6.6 is where two of those three jobs will start becoming their Giga versions.
Eidos will upgrade Sei’s storage layer, and Ares will upgrade Sei’s execution client to the Giga executor. Both need to keep pace with the 200,000 TPS that Sei Giga is targeting.
These upgrades will begin in 6.6 and continue in future releases. Consensus, the third major part of the Giga Upgrade, will only go live later.
How Eidos changes storageEidos will begin moving the chain’s history out of a shared database and into one built for the job. In 6.6, the historical state migration will start.
Until now, Sei’s EVM history and Cosmos state have lived in the same database. That means history reads compete with live activity, and modules that have nothing to do with the EVM still pay write costs for EVM data.
Eidos will separate them. EVM history will move into its own dedicated database, so reading old history stops competing with the transactions happening right now, and non-EVM parts of the chain stop carrying the write cost of EVM data they never touch.
How Ares changes executionAres is a rebuilt execution client, and in 6.6 it will become the default execution path on mainnet. Every upgraded node will run it unless it opts out.
Ares is a different design from what came before. Where the old v2 engine used a Go-native path, Ares is built on an EVMC backend with evmone as the interpreter, and it runs its own state and cache stack.
The old engine will keep two roles.
First, it will act as a per-transaction fallback. When Ares hits something it can’t handle cleanly, that single transaction will rerun on the v2 engine instead of the new engine guessing at the result. Nothing gets dropped or approximated. The fallback catches the edge case and the block moves on.
Second, a full v2 node will run on every network as a live reference. It will process the same blocks as the new engine and compare results block by block. If the two ever disagree, it will page the on-call team. That means a mismatch between the old and new execution paths becomes an alert a human sees, not a silent divergence that surfaces later as a bug.
What comes next6.6 will be the release where Giga stops being a roadmap and starts being something running on mainnet. Eidos will have begun moving history into storage built for scale, and Ares will be the default execution path. Both are only the first step, and both continue across the releases that follow.
6.6 is a massive release, with many fixes that are unrelated to Sei Giga. The full list is in the 6.6 proposal.
Sei Labs Tables Quantum-Security Upgrade@SeiNetwork has put forward SIP-5, a governance proposal that would give $SEI holders the option to upgrade their account security to a post-quantum cryptography (PQC) standard. The proposal is designed to be additive rather than disruptive: users would keep their existing addresses and balances while layering on a new quantum-resistant key, with no obligation to act until quantum computing presents a credible real-world threat.
The move positions Sei as one of the first high-throughput layer-1 networks to formally address the long-term risk that quantum hardware poses to public-key cryptography. Quantum computers pose a significant threat to blockchain technology's security, which heavily relies on public-key cryptography. The cryptographic algorithms used in blockchains, based on large prime numbers and discrete logarithms, can be compromised by quantum computing algorithms such as Shor's algorithm. By embedding an upgrade path at the protocol level now, Sei aims to give users a clear migration route well before that risk becomes acute.
A Pragmatic, Opt-In ApproachWhat makes SIP-5 notable is its user-friendly framing. Rather than forcing a network-wide migration, the proposal allows accounts to opt in on their own schedule, preserving backwards compatibility. Pure quantum-resistant deployments remain rare, and hybrid approaches combining classical and post-quantum algorithms are expected to dominate near-term implementations. This pragmatic strategy provides defence-in-depth while allowing organisations to maintain operations with current and legacy systems. SIP-5 follows a similar logic, letting users hold both key types in parallel.
Post-quantum cryptography uses much larger signatures and higher verification costs, which can strain high-throughput blockchains. Sei contributors say the network's design is well suited to approaches like proof batching and recursive verification. Rather than viewing quantum resistance as a simple key swap, Sei is treating it as a broader systems challenge that must work alongside extreme performance.
The wider crypto industry is watching the quantum threat closely. NIST finalised three post-quantum cryptographic standards in August 2024, and any blockchain project that has not begun a post-quantum cryptography assessment as of 2026 is operating outside the bounds of responsible security practice. SIP-5 signals that Sei intends to be ahead of that curve rather than behind it.
No timeline for a vote or implementation has been confirmed at the time of writing. The proposal remains open for community discussion.

ScienceDirect: Navigating the Quantum Computing Threat Landscape for Blockchains
TL;DR: Sei Labs has shared a new proposal, SIP-5, that lays out how existing accounts can stay safe once quantum computers are powerful enough to break today’s cryptography. The plan lets users keep current addresses and balances, allowing you to add a quantum-resistant key when you are ready, and does it all well before any real threat exists.
What is SIP-5Every EVM blockchain today rests on the same kind of cryptography. It works because the math behind it is impossible for classical computers to reverse. A powerful enough quantum computer would change that. In theory, it could take a public key that has already been seen onchain and work backward to the private key that controls the account.
That machine does not exist yet, but many experts believe the timeline for one is accelerating. The point of SIP-5 is to introduce a solution well before a threat exists.
SIP-5 is Sei Lab’s proposed path for upgrading existing accounts to quantum-resistant security without breaking anything people already rely on. It is a proposal, shared openly, so the ecosystem can look at it and decide together how to move forward.
Why this is the right time to talk about itQuantum computers capable of breaking today’s signatures are not here. Waiting until the threat is imminent, however, means designing the fix under pressure. Rushing such an upgrade could introduce many implementation risks.
SIP-5 takes the opposite stance. It proposes adding the quantum-resistant option far in advance, so the solution is in place well before the threat exists. And, if the timeline moves faster than anyone expects, the network is already prepared.
What it would mean for account holders on SeiYour address will stay the same. Your balance will stay the same, as will your transaction history, approvals, and the contracts you interact with. SIP-5 is built specifically to avoid forcing users to abandon their old accounts.
Under SIP-5, when you are ready, you attach a new quantum-resistant key to your existing account. From that point on, the account would be protected by the new key. Under the proposal, you would also choose your own pace. You can move early if you want the extra security sooner, or you can wait.
The real trade-offsThis approach has two trade-offs, which is why Sei Labs is not proposing it as something to immediately be implemented.
The first is that there is a future cutoff point, set by governance if and when the plan is adopted, after which an account can only continue to send transactions if it has already added its quantum-resistant key.
An account that never adds one would still be able to receive funds, but it would no longer be able to send. That is the practical reason the option is being introduced so far ahead of time. The window to prepare is meant to be long and unhurried, which is only possible if the conversation starts now.
The second trade-off is that upgrading to post-quantum signatures will slow the performance of every EVM blockchain. Today’s post-quantum signature schemes are many times larger than existing signature schemes. That means bigger messages to broadcast across the network, so fewer can be sent at once.
To solve for these tradeoffs Sei Labs is simultaneously proposing the emergency solution that SIP-5 provides, and beginning work on finding an even better solution through new, high-performance post-quantum cryptography.
Where this fitsSIP-5 is a proposal and it is written that way on purpose. It defines the minimum needed to keep accounts working across a quantum transition and leaves the bigger governance decisions for the moment they actually become relevant. Wallets, explorers, and other tooling would need time to add support, and the proposal calls for that groundwork to be in place before any cutoff is ever set.
A network built for modern trading has to plan for long term threats that are not immediate today. SIP-5 is what that looks like in practice.

The Sei Giga Whitepaper V2 is a major update to the original Giga Whitepaper published in May 2025. It introduces significant performance improvements and new features to Sei Giga, redesigning Sei Network from first principles into a blockchain with the ideal architecture for onchain trading.
Read the full whitepaper at: https://arxiv.org/pdf/2505.14914
What's New in V2The updated whitepaper addresses the questions the original left open. Where v1 described how Giga achieves speed and throughput, V2 adds how it will solve for privacy and fairness.
Faster FinalityThe new whitepaper introduces even faster performance for Giga's Autobahn consensus protocol. It now targets sub-250ms finality, down from the 400ms target in the original whitepaper. This will be delivered while maintaining 200,000+ transactions / 5 gigagas per second throughput across the network’s decentralized validator set.
Pre-Execution Privacy and MEV ResistanceThe new whitepaper introduces Sedna, a private transaction layer.
Transactions on Sei Giga will be encoded into fragments and distributed across multiple proposer lanes. This will ensure that no proposer will see the full contents of a transaction until ordering is finalized, giving the network pre-execution privacy. In short, a trade will never be visible until it is executed.
It also introduces a deterministic mechanism for ordering transactions across proposer lanes. This will make transaction ordering transparent, predictable, and secure against manipulation by any individual proposer.
Ultimately, Sedna will almost completely remove the MEV and censorship risk that affects every other smart contract blockchain.
The original Giga breakthrough: multi-proposer consensusIn traditional blockchains, one validator at a time is chosen to propose a block. That validator collects transactions, builds the block, broadcasts it, and then everyone votes on it across multiple rounds before it's finalized. Everything happens in sequence. You can't start the next block until the current one finishes the full propose-vote-vote-commit cycle. The speed of the entire chain is bottlenecked by one proposer at a time and multiple rounds of back-and-forth messaging.
Autobahn throws out that sequential model. Instead of one leader proposing blocks while everyone else waits, every validator will run its own "lane" and continuously stream batches of transactions in parallel. Each validator will propose independently and get a lightweight proof that its data is available from a small quorum of peers -- without requiring everyone to download everything upfront. A designated leader will then periodically take a snapshot called a "tip cut" that will capture the latest batch from every lane and commit them all at once through a streamlined two-phase vote.
This is what will enable Sei Giga’s immense throughput. Instead of being limited to however many transactions one validator can fit into one block per round, every validator will produce data simultaneously, and the consensus layer will synthesize their outputs together, sorting them deterministically by priority fee. The raw throughput ceiling will go from "one proposer's bandwidth" to the aggregate bandwidth of the entire validator set.
The Optimal Design for Institutional TradingBlockchains offer significant advantages over traditional trading venues. These include near instant settlement, shared liquidity, composability and 24/7 markets. However, in spite of these advantages, traditional traders are yet to adopt blockchain technology at scale.
For a trading environment to be successful, it has to be predictable. Trading on layer one blockchains today, because of the risks posed by MEV and possible censorship from block builders, is not predictable. This makes today’s blockchains fundamentally unsuitable for institutional traders.
When trading has taken off onchain, it has done so on venues which make the tradeoff of adopting centralized designs in order to make market structure more predictable. However in doing so, these exchanges expose themselves to the same centralization risks that affect legacy trading venues.
Sei's Giga upgrade will take the completely novel approach of introducing a multi-proposer architecture, and combining it with a private transaction dissemination layer. The result will be the first layer one blockchain that is actually suited for trading at scale. Sei Giga will offer pre-execution privacy, fair transaction ordering, MEV resistance, and censorship resistance while ensuring high throughput and near instant settlement.
Sei Giga will be the blockchain for trading.
What's NextSei Labs is well underway with the Giga Upgrade. Progress towards Giga can be followed on Sei Labs’ Giga Roadmap.
The whitepaper's future work section outlines several areas of active development:
Full transaction fee mechanism Autobahn consensus upgradesNew tokenomics for the SEI token The Giga upgrade will be the most complex blockchain upgrade since Ethereum's Merge. The network will transition to the full Giga protocol without regenesis and without taking any element of the network offline.

Disclaimer: The roadmap is subject to change based on development progress, market feedback, and other factors. Actual timelines, figures, and outcomes may vary.
@SeiNetwork has published the second version of its Giga Whitepaper, the first revision since the original dropped in May 2025. The update tightens one of the network's core performance targets and adds a new transaction privacy layer aimed at institutional traders.
What Changed in V2The headline change is a tighter finality target. The revised whitepaper pushes the goal down to sub-250ms, an improvement on the sub-400ms figure that has been the benchmark since the original Giga paper. The throughput target of 200,000+ transactions per second is unchanged from V1. Sei Labs first published the Giga whitepaper on May 19, 2025, positioning the project as the first multi-proposer EVM layer-1 blockchain. V2 refines that foundation rather than replacing it.
The upgrade is also designed to land without a regenesis or taking the network offline, reducing disruption for applications already running on the chain.
Sedna: A Private Transaction Layer Across Multiple LanesThe most significant new addition in V2 is Sedna, a private transaction layer built to reduce MEV and front-running risk. Rather than broadcasting full transaction data to all proposers at once, Sedna breaks each transaction into fragments and distributes them across separate proposer lanes. No single proposer can see the full details of a trade before it is finalized. Execution then follows a deterministic order once enough fragments are available. The practical effect is that would-be front-runners cannot read a pending transaction in time to act on it.
Paired with deterministic ordering across those lanes, Sei says the design nearly eliminates MEV and censorship risk, two concerns that have historically kept institutional trading activity away from most layer-1 blockchains. The upgrade targets all three factors institutions care about: latency, throughput, and predictable ordering.
Sei Labs co-founder Jayendra Jog previewed the efficiency case for the approach in a mid-June interview, noting that Sedna would deliver roughly 90 percent of the privacy benefits of a full zero-knowledge layer while requiring just 0.01 percent or less of the implementation effort. The full technical specification is set out in the Sedna protocol research paper on arXiv. The public milestone tracker for the full Giga rollout is available at giga.seilabs.io.
