Arbitrum Security Council Freezes $71 Million in Ether Linked 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, locking down approximately $71 million worth of ether, which is roughly 30,766 ETH. This move was made in response to the $292 million rsETH exploit that occurred on Saturday. The frozen funds, now held in an intermediary wallet, can only be accessed through additional governance actions. The rsETH token represents a user's stake in restaked ether and is issued by KelpDAO. Law enforcement provided input on the exploiter's identity, prompting the Security Council to act. The freeze was executed without disrupting any users or applications on Arbitrum. According to Arbitrum's statement, the transfer was completed at 11:26 p.m. ET on April 20. This action recovers about a quarter of the total amount stolen from Kelp's LayerZero-powered bridge on Saturday, when 116,500 rsETH were exploited due to compromised verifier infrastructure. The attack has been attributed to North Korea's Lazarus Group with preliminary confidence by LayerZero. As a layer-2 blockchain, Arbitrum processes transactions more efficiently and settles them on the main Ethereum chain. Its Security Council has emergency powers to intervene in such scenarios, although governance-level actions on user funds are rare and can be contentious. The freeze provides Kelp with a partial recovery option, in addition to any potential recoveries by law enforcement and chain-tracing firms. It also heightens the ongoing dispute between Kelp and LayerZero regarding responsibility for the exploit, as any further socialization of losses now has a $71 million offset. Kelp is coordinating with ecosystem partners on a recovery fund and considering next steps, including unpausing, loss socialization, and legal coordination. The potential for freezing additional stolen funds depends on the attacker's movements of rsETH or its derivatives and whether other chains with similar powers choose to act.
