Summer.fi Attacker Moves 1.35 Million DAI to Tornado Cash via Uniswap

Security monitors have identified new movement from the wallets associated with the Summer.fi exploit. On July 9, 2026, on-chain data revealed that the attacker initiated a series of transactions to obfuscate the trail of stolen funds. The perpetrator successfully converted 1.35 million DAI into Ethereum (ETH) using the decentralized exchange Uniswap before routing the assets through the privacy protocol Tornado Cash.

Detailed Breakdown of On-Chain Movements

According to data provided by Onchain Lens, the primary attacker wallet, identified by the address 0x7BF...b3bdca, originally received a total of 6.017 million DAI following the breach of the Summer.fi protocol. In the latest sequence of events, the attacker transferred a portion of these funds to a secondary intermediary wallet (0x46e...eba7).

The following steps were observed during the laundering process:

• The transfer of 1.35 million DAI from the primary exploit wallet to a secondary address.
• The execution of a swap on Uniswap, exchanging the stablecoins for ETH.
• The subsequent transfer of the acquired ETH into Tornado Cash, a mixing service frequently used to mask transaction histories.

Current Status of Stolen Assets

Despite the recent activity, a significant portion of the illicitly obtained funds remains under the attacker's control in transparent addresses. Blockchain analysts confirm that the original wallet still maintains a balance of approximately 4.67 million DAI. Furthermore, the secondary wallet used for the Uniswap conversion currently holds an additional 50 ETH that has not yet been moved to a mixer or exchange.

The incident highlights the ongoing challenges faced by decentralized finance (DeFi) platforms in securing liquidity pools against sophisticated exploits. While Summer.fi and security researchers continue to monitor the situation, the use of non-custodial mixers like Tornado Cash complicates the recovery process for affected assets. Cyber-security firms remain on high alert for further movements from the remaining 4.67 million DAI.
