Gnosis Chain Warns Validators of Penalties After Balancer Hack Recovery

Gnosis Chain executed a governance-approved hard fork on December 22 to recover approximately $9.4 million in frozen funds from the Balancer hack.

  • The funds were initially frozen following a validators-approved soft fork in November 2025.
  • Gnosis node operators had ten days to upgrade and execute the hard fork for fund recovery.
  • The official Gnosis account warned remaining validators to upgrade their nodes to avoid penalties, which could include loss of staking rewards or slashing.
