Analyse : Le hacker ETH de KelpDAO gelé par Arbitrum est une transaction de niveau système, injectée par le comité de sécurité via ArbOS

Mars Finance information, April 21 — Dragonfly managing partner Haseeb Qureshi released an analysis regarding “Arbitrum Security Council freezing KelpDAO hacker’s 30,766 ETH” stating that this transaction type is 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 through ArbOS. This operation did not perform chain rollback or historical rewriting; functionally, it is a state-level recovery: the attacker’s private key can still sign transactions, but the ETH of that address is transferred by the chain itself. This operation also demonstrates the powers of the Security Council as described in Arbitrum’s progressive decentralization documentation under “catastrophic emergency” situations.
