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

A significant portion of the Kelp DAO funds is now inaccessible. Arbitrum's Security Council has frozen approximately $71 million worth of ether, moving 30,766 ETH linked to the recent $292 million rsETH exploit into a secure intermediary wallet. This wallet can only be accessed through additional governance actions. The frozen funds are part of the rsETH, a liquid restaking token representing a user's position in restaked ether. The Security Council took emergency action, with input from law enforcement regarding the exploiter's identity, to freeze the funds without impacting 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 on Saturday. 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 take protective action. However, governance-level interventions on user funds are rare and controversial due to the introduction of discretionary control over an otherwise permissionless network. The freeze provides Kelp with a partial recovery option, in addition to any further actions law enforcement and chain-tracing firms can take. It also escalates the dispute between Kelp and LayerZero over 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 on unpausing, loss socialization, and legal coordination with affected counterparties. The possibility of freezing more stolen funds depends on the attacker's movements of rsETH or its derivatives and whether other chains with similar emergency powers choose to act.
