Arbitrum's Security Council just hit the pause on 30,766 ETH (~$70M) of stolen funds related to this weekend's KelpDAO exploit, reigniting debate about when blockchains have a responsibility to intervene.
• Frozen ETH: Arbitrum’s Security Council has frozen 30,766 ETH tied to the Kelp DAO exploit, sending the funds to a DAO-controlled address that can only move funds with the approval of Arbitrum governance approval, halting any further unauthorized movement of the funds on its L2 network.
• Partial Containment: Although the total scope of the KelpDAO exploit was far larger (~$290M), with the attacker laundering funds through truly decentralized networks like Ethereum and Thor Chain where stolen proceeds are unlikely to be seized, this recovery will provide meaningful relief for impacted DeFi protocols.
If a blockchain is centralized enough to freeze funds of malicious actors, it arguably has a moral responsibility to act. That capability, however, signifies a level of control that invites regulation and formal oversight.
