Arbitrum Secures $71 Million in Ether Tied to Kelp DAO Exploit

A significant portion of the funds stolen from Kelp DAO is now frozen. Arbitrum's Security Council took swift action on Monday, moving 30,766 ETH, worth roughly $71 million, into a secure intermediary wallet that can only be accessed through further governance decisions. This action was taken in response to the $292 million rsETH exploit that occurred on Saturday. rsETH is a token representing a user's stake in restaked ether. The Security Council, acting on information provided by law enforcement regarding the exploiter's identity, 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 about a quarter of the total amount drained from Kelp's LayerZero-powered bridge, which was exploited by attackers who pulled 116,500 rsETH by compromising verifier infrastructure. The stolen funds are no longer under the control of the original address. Arbitrum, a layer-2 blockchain, has a Security Council with emergency powers to protect the network. However, such interventions on user funds are rare and can be controversial due to the introduction of discretionary control. The freeze provides Kelp with a partial recovery option, in addition to any further recoveries made by law enforcement and chain-tracing firms. It also escalates the dispute between Kelp and LayerZero over who bears responsibility for the exploit, as any broader socialization of remaining losses now has a $71 million offset. Kelp is coordinating with ecosystem partners on a recovery fund and considering next steps, while LayerZero has not publicly commented on the Arbitrum freeze. The ability to freeze more stolen funds depends on the attacker's movements of rsETH or its derivatives and whether other chains choose to act.
