A hacker address implicated in the exploit of Mixin network is back to life after two years of inactivity. As flagged by Lookonchain, the hacker’s wallet address appears to be selling the siphoned funds with the aid of popular crypto mixer Tornado Cash.

Ethereum sell-off initiated by Mixin hackerPer the insight from Lookonchain, in the past 15 hours, the hacker has sent 2,005 Ethereum, valued at $3,850,000, to Tornado Cash. This marked the start of other transactions, as three new wallets also received 2,087 ETH.

These fragmented ETH have a value of $4.03 million, and through Tornado Cash, they were sold at a market price of $1,933. As of writing time, the price of Ethereum was changing hands for $1,971.30, implying that the hacker sold at a loss with differences in valuation.

As with many scam alert trends, attackers often lie low after their exploit to stall investigations into their nefarious acts. Mixin network was exploited in 2023, with the hacker siphoning 57,849 Ethereum worth $113.4 million.

At the time, the exploit also led to the loss of 891 BTC, worth $59.7 million, and 23.57 million USDT, which was converted into DAI stablecoin.

More selling pressure for ETHThe market sentiment around Ethereum is growing more negative as different sell-off avenues have emerged in the past 24 hours.

U.Today previously noted that BlackRock moved millions in Ethereum to Coinbase, extending its dump of the largest altcoin. With less observable Ethereum retail accumulation to shift the trend, the price of ETH is poised to remain in a deep drawdown in the coming weeks.

While Bitmine is helping to cushion the sell-off with purchases and staking of the Ethereum in its treasury, the net sell-off needs to reverse for an ultimate price rebound. As of writing time, the coin was priced at $1,970, down 1.3% in the past 24 hours, per CoinMarketCap data.

The Mixin hacker has resurfaced after two years of dormancy, now making efforts to launder parts of the 59,000 Ethereum stolen from the exploit.

The Mixin network exploiter, who drained about $200 million worth of Ethereum (ETH), Bitcoin (BTC), and other crypto assets from the Hong Kong-based network, appears to have begun laundering the ETH assets, recently transferring 2,005 ETH tokens to Tornado Cash.

Interestingly, the latest transaction originated from the original exploiter address after two years of dormancy and has reduced its Ethereum stash to 57,802 tokens worth $113.58 million at press time. 

Key Points The Mixin network hacker has resurfaced after two years of dormancy, with early efforts to launder the Ethereum tokens stolen from the exploit. In the latest transaction, the original exploiter address moved 2,005 ETH worth nearly $4 million to crypto mixer Tornado Cash. Following the transaction, the hacker now holds 57,802 ETH valued at $133.58 million and 891 BTC worth nearly $60 million. The Mixin network hack was a high-profile exploit that drained $200 million worth of crypto assets from the Hong Kong-based P2P network. Details of the Recent Transactions The recent transactions were indexed by Lookonchain, a leading blockchain surveillance platform, today. On-chain data confirms that the asset movements began yesterday at 09:22 PM UTC, involving the transfer of exactly 2,005 ETH worth $3.996 million to an unidentified wallet, 0x9…87f.

Note that #MixinHacker, who previously stole $200M, appears to be selling 59,854 $ETH($117M) after 2 years of inactivity!

15 hours ago, he sent 2,005 $ETH($3.85M) to #TornadoCash.

Soon after, 3 new wallets received 2,087 $ETH ($4.03M) from #TornadoCash and sold it at $1,933.… pic.twitter.com/8ujC2Berfz

Interestingly, the wallet is relatively new, with the 2,005 ETH transfer being its first transaction. Barely a minute after receiving the tokens, 0x9…87f started moving the tokens to Tornado Cash in batches of 100 ETH transactions each. The address made 20 of these transfers to Tornado Cash, totaling 2,000 ETH. Currently, it has retained 5 ETH tokens. 

Meanwhile, Lookonchain found that, shortly after the transfers to Tornado Cash, three new wallets purportedly connected to the Mixin hacker emerged and received a total of 2,087 ETH tokens from Tornado Cash across multiple transactions of about 99 ETH each. The wallets sold all the tokens for $4 million in DAI.

At press time, the Mixin network hacker still holds 57,802 ETH tokens worth $133.58 million. Meanwhile, the Bitcoin address recorded no new movements during this time, remaining dormant since receiving 891 BTC during the September 2023 exploit.

The Mixin Hack For the uninitiated, the Mixin Network hack ranks among the largest crypto thefts of 2023. The breach targeted the Hong Kong-based peer-to-peer digital asset platform. On Sept. 23, 2023, attackers infiltrated the database of Mixin’s cloud service provider, compromising the network’s mainnet hot wallets.

Mixin confirmed the incident two days later, stating that the attack led to losses initially estimated at about $200 million. The platform immediately suspended deposit and withdrawal services while keeping peer-to-peer transfers active. 

How the Hack Occurred Notably, the attackers exploited a centralized cloud database that handled user accounts, session management, and hot wallet access. Although Mixin used a custom kernel with a directed acyclic graph structure for cross-chain transfers, the reliance on centralized infrastructure created a single point of failure. 

After breaching the database, the hackers gained access to hot wallet controls and executed thousands of transactions to extract the funds.

On Ethereum, the attackers drained 59,808 ETH through more than 10,000 transactions across over 11,400 wallets. They also transferred 891 BTC in three transactions from 127 wallets. In addition, they removed 23.57 million USDT and quickly swapped it for DAI on decentralized exchanges. 

Total tracked losses reached roughly $144.1 million, with other assets bringing Mixin’s internal estimate closer to $200 million. Investigators linked portions of the funds to wallets previously associated with the Lazarus Group. Notably, the ETH and BTC assets remained dormant until the recent 2,005 ETH transfer.

In brief A hacker wallet dormant since 2023 moved $3.85M in Ethereum from the Mixin exploit to Tornado Cash on Thursday. The Mixin exploit, which took place in September 2023, drained roughly $200M across multiple blockchains. Mixin plans a full repayment of $23M in MDTu tokens by September 2026. A wallet linked to the 2023 Mixin hack, which resulted in the loss of $200 million, has moved $3.85 million into a new wallet that then immediately sent the funds to coin mixer Tornado Cash.

The first transaction in two years took place late Thursday night, as the Mixin Hacker wallet—which has been tagged by blockchain analytics platform Arkham Intelligence—moved $3.85 million worth of Ethereum to an unknown wallet 0x9c. That wallet then immediately sent all of the funds to Tornado Cash in 20 separate transactions.

The Mixin exploit dates back to September 2023, when Hong Kong-based crypto platform Mixin Network suspended deposits and withdrawals after hackers drained roughly $200 million from its cloud service provider’s database.

The breach affected assets across multiple chains, making it one of the larger cross-chain infrastructure hacks of the year. Mixin later said it would compensate users up to 50% of their losses in stablecoins, with the remainder issued as tokenized claims.

The Mixin team said on X at the time that it had contacted Google and blockchain security firm SlowMist to help with the investigation.

The attacker-controlled wallet had remained largely dormant for nearly two years before moving $3.8 million on February 12, 2026.

In October 2025, the Mixin Network provided an update on its repayment of users who were impacted by the exploit.

"Following the incident, Mixin Network initiated a debt registration and repayment process, and issued the Mixin Debt Token (MDT) series, including MDTu, MDTb, and MDTe, each representing claims for different categories of affected assets," the team wrote in its blog post.

The team said it intends to fully repay debt represented by MDTu, worth approximately $23 million, but September 23, 2026, but that there's currently no repayment schedule for MDTb and MDTe.

Mixin did not shut down after the exploit. It still claims to have more than $1 billion worth of assets under management and more than 1 million customers. The team manages a crypto wallet, custody services, and trading infrastructure.

Mixin, the privacy-first transactional platform for digital assets, is expanding its gas fee subsidy program, enabling users to transfer assets across multiple blockchains with effectively zero net transaction costs.

Originally launched in 2025, the program allows users to import external Web3 wallets into the Mixin ecosystem and execute on-chain transactions while paying gas fees upfront, which are then fully reimbursed to their wallets at the beginning of the following month, effectively removing one of the most persistent barriers to everyday crypto usage.

Gas fees have long made small and frequent transactions impractical, particularly during periods of network congestion. Mixin’s subsidy model addresses this challenge by significantly improving the user experience, making everyday transfers across supported networks more accessible and cost-efficient.

"Our goal has always been to make cryptocurrency as simple and private as sending a text message," said Cedric Fung, Co-Founder of Mixin. "Gas fees have been one of the biggest barriers to everyday crypto usage. By subsidizing those costs across supported networks, we’re removing friction from how people move value online."

Once a Web3 wallet is imported into Mixin, users can transfer assets between imported wallets, move funds between Mixin Privacy Wallets and the imported  Web3 wallets,. The subsidy currently applies to major assets and networks including BTC, ETH, and SOL, alongside other supported chains. At present, there are no limits on the number of transactions or transfer amounts under the program.

It is important to note that transfers conducted within Mixin’s Privacy Wallet remain natively fee-free and are settled instantly via Mixin’s decentralized network. These transactions operate independently from the subsidy mechanism applied to on-chain transfers involving imported Web3 wallets.

This upgrade is part of Mixin’s broader effort to integrate encrypted messaging with privacy-focused financial infrastructure. Built using the Signal Protocol for end-to-end encrypted communication, the platform enables users to coordinate payments privately while managing assets within a chat-based interface.

"The future of finance is social, private, and multi-chain," Fung added. "Mixin is building a messaging layer where people can communicate, coordinate, and move value without friction."

About MixinMixin is an open-source decentralized transaction network designed to connect multiple blockchains with high throughput and strong privacy guarantees. Founded in 2017, the platform combines a self-custodial multi-chain wallet with an encrypted messenger powered by the Signal Protocol. With more than 1 million users and over $1 billion in user-managed assets, Mixin continues to develop infrastructure aimed at simplifying the everyday use of digital assets.

Mixin expands gas subsidy program to make multichain transfers easier

Hong Kong, China, May 22nd, 2026, Chainwire

Mixin today announced the launch of Bitcoin Lightning Network support, enabling users to send, receive, and manage Lightning BTC directly inside the Mixin app.

The integration brings Lightning payments into Mixin’s wallet experience, allowing users to make Bitcoin transfers without managing nodes, payment channels, or complex Lightning configurations. Each Mixin user also receives a free Lightning Address, such as [email protected], creating a reusable Bitcoin payment identity for everyday transactions.

Bitcoin Payments Inside the Mixin App

With Lightning Network support, users can now access Bitcoin payment functionality directly in Mixin, including:

Sending and receiving Lightning BTC Making near-instant BTC transfers with lower network costs Using a reusable Lightning Address for payments Accessing Lightning payments without running nodes or managing channels This makes Bitcoin payments easier to use for real-world scenarios such as peer-to-peer transfers, cross-border payments, tipping, creator payments, community transactions, and merchant acceptance.

Free Lightning Address for Every User

Mixin now provides every user with a free Lightning Address, such as [email protected].

A Lightning Address works like an email-style payment identity, allowing users to receive Bitcoin payments through a persistent and shareable address instead of generating a new Lightning invoice for each transaction.

This improves usability for merchants, creators, communities, and frequent BTC receivers who need a simple way to accept Bitcoin payments.

No Nodes, No Channels, No Complex Setup

Traditional Lightning usage often requires users to understand nodes, channels, liquidity management, and invoice generation.

Mixin removes this complexity by integrating Lightning payment functionality directly into the app. Users can send and receive Lightning BTC through a familiar wallet interface, making Bitcoin payments more accessible to everyday users.

Expanded Support for Bitcoin-Native Assets

In addition to Lightning BTC transfers, Mixin supports deposits of BTC, USDT, and Taproot Assets within the Lightning ecosystem.

This expands Mixin’s Bitcoin payment capabilities beyond BTC alone and creates more flexible asset transfer options for users interacting with Bitcoin-native assets and Lightning-compatible services.

Broad Lightning Ecosystem Compatibility

Mixin supports multiple Lightning Address formats for outgoing payments, helping users interact with external Lightning wallets, applications, and services.

By combining Lightning payments, free Lightning Addresses, and support for Bitcoin-native asset deposits, Mixin is expanding its role as a practical payment wallet for the Bitcoin ecosystem.
