The Arbitrum asset freeze secured approximately $30.5 million in cryptocurrency linked to the Binance hack on October 30, 2026. Arbitrum’s Security Council moved the assets into a restricted wallet, but they have not been returned to Binance.

Key Takeaways

  • The intervention secured 8,425 ETH and 74,559,805.2 ARB held by an address identified with the exploit.
  • The funds can move only after an ArbitrumDAO governance vote.

How the Arbitrum asset freeze worked

The Security Council acted at 8:08 a.m. Hong Kong time, transferring the assets on Arbitrum One to an intermediary wallet ending in 0DA0. Arbitrum’s emergency action disclosure says the funds can be moved only through an ArbitrumDAO governance vote, coordinated with relevant parties.

To carry out the transfer, the council temporarily upgraded Arbitrum’s inbox contract on Ethereum. The change enabled transactions that impersonated the identified address and moved its ETH and ARB without authorization from the holder. The contract was then restored to its original implementation.

Arbitrum said no other users’ funds or applications were affected. The intervention used network infrastructure rather than a freeze imposed by a token issuer.

Binance response and the funds’ status

Binance estimated that the broader security breach affected approximately $6.3 billion in cryptocurrency and said roughly $3 billion had been frozen across blockchain networks and token issuers. The exchange pledged to cover customer losses using its emergency reserve and corporate funds.

The Arbitrum assets remain secured rather than returned. Their eventual disposition depends on governance decisions and coordination with relevant parties.
