Arbitrum council moved $30 million in Binance hack funds without the hacker's key

What sources claim

• CoinDesk reported that a 12-person committee briefly rewrote one of Arbitrum's core contracts to spend from an address it held no key for, then put the code back.
• CoinDesk reported that the council moved $30 million of funds from the Binance hack.
• CoinDesk reported that this was the second time the council took this action this year.

Still unresolved

• Which specific core contract was modified and what code changes were made to enable the spend would need an official Arbitrum statement, governance post or on-chain transaction record to confirm.
• Whether the recovered $30 million was returned to Binance, distributed to users or otherwise allocated would need an official statement from Arbitrum or Binance, or on-chain data, to confirm.

Evidence levels describe source coverage, not the probability that a report is true. Price moves and their timing cannot establish a cause; minute samples show an observed interval and alert thresholds are heuristics. Explanations are model-assisted, with citations and figures checked. Source titles stay in their original language; full articles are not republished.
