Dragonfly Socio de gestión: El Comité de Seguridad de Arbitrum inyecta permisos de emergencia usando ArbitrumUnsignedTxType para transferir fondos del atacante

Golden Finance reports that on April 21, Dragonfly managing partner Haseeb Qureshi issued an analysis regarding “the Arbitrum Security Council transferring 30,765 ETH held by the Kelp DAO attacker to a secure address and freezing it” through a technical solution. The transaction type is identified as ArbitrumUnsignedTxType (EIP-2718 type 0x65/101), which is a system-level transaction that cannot be signed by a regular EOA and can only be injected by the Arbitrum Security Council via ArbOS. This operation did not involve chain rollback or history rewriting; functionally, it is a state-level recovery: the attacker’s private key can still sign transactions, but the ETH at that address is transferred by the chain itself. This operation also demonstrates the authority of the Security Council described in Arbitrum’s gradual decentralization documentation under “catastrophic emergency” conditions.
