Gnosis Chain hard fork on Dec 22, 2025 to recover $9.4M from Balancer exploit

Gnosis Chain said it activated a hard fork on December 22, 2025 to recover roughly $9.4 million that had been frozen after the November 2025 Balancer V2 exploit. The project disclosed the move on December 23, adding the assets were no longer under the attacker’s control and urging remaining node operators to update, a step that has prompted debate over governance and immutability.
