Arbitrum Security Council Triggers Emergency Powers to Move 30,765 ETH From Kelp DAO Attacker

ME News reported that on April 21 (UTC+8), Dragonfly Managing Partner Haseeb Qureshi broke down Arbitrum's Security Council action to secure 30,765 ETH linked to the Kelp DAO attacker. The council transferred the funds to a secure address and froze them using an ArbitrumUnsignedTxType transaction (EIP-2718 type 0x65/101). Qureshi said this is a system-level transaction that cannot be signed by a standard EOA and can only be injected into ArbOS by the Arbitrum Security Council. He emphasized the move did not roll back the chain or rewrite history. Instead, it functioned as a state-level recovery: the attacker's private key can still sign transactions, but the ETH previously held at that address were reassigned by the network itself. The episode also highlights the Security Council's mandate under "catastrophic emergency" conditions, as outlined in Arbitrum's Progressive Decentralization documentation. (Source: Foresight News)
