Arbitrum Secures $71 Million in Ether Linked to Kelp DAO Security Breach

A significant portion of the Kelp DAO funds is now frozen. Arbitrum's Security Council took action on Monday night, securing approximately $71 million worth of ETH by transferring 30,766 ETH linked to Saturday's $292 million rsETH exploit into a holding wallet. This wallet can only be accessed through additional governance procedures. The frozen funds are part of the stolen rsETH, a liquid restaking token representing a user's position in restaked ether. The Arbitrum Security Council acted in conjunction with law enforcement, who provided input on the exploiter's identity. The council executed the freeze without disrupting any Arbitrum users or applications. The transfer was completed at 11:26 p.m. ET on April 20. This move recovers roughly a quarter of the total amount drained from Kelp's LayerZero-powered bridge on Saturday. The stolen funds are no longer controlled by the original address. Arbitrum, a layer-2 blockchain, has a Security Council with emergency powers to take protective action in such scenarios. However, interventions on user funds are rare and controversial due to the introduction of discretionary control. The freeze provides Kelp with a partial recovery option, in addition to any further recoveries by law enforcement and chain-tracing firms. This development also escalates the dispute between Kelp and LayerZero over responsibility for the exploit. Kelp is coordinating with ecosystem partners on a recovery fund and considering next steps. The ability to freeze additional stolen funds depends on the attacker's movements of rsETH or its derivatives and whether other chains choose to act.
