Arbitrum Security Council Transferred Assets Related to Binance Hack

The Arbitrum Security Council executed an emergency action on October 30, transferring 8,425 ETH and approximately 74.56 million ARB tokens—assets linked to addresses connected to the Binance hack—to a custodial address, according to a November 3 announcement. To execute the transfers, the council temporarily upgraded Arbitrum's Inbox contract, simulating two cross-chain transactions from the affected addresses, then restored the original contract code afterward. The assets are tied to funds stolen in the Binance security incident, and the council moved them to prevent further movement by the attackers. Any subsequent movement of the funds now requires a governance vote by the ArbitrumDAO. The action highlights the council's emergency powers over the layer-2 network's bridge assets and raises governance questions about unilateral intervention. Watch for the ArbitrumDAO vote on the assets' disposition and any further recovery efforts tied to the Binance exploit.
