Zano Rolls Back Blockchain After Gateway Address Exploit

Zano has taken drastic measures to address a vulnerability in its blockchain system. The project restarted its network at block 3,833,000, effectively rolling back about a month of activity tied to an exploit linked to Gateway Addresses.

The rollback removes both legitimate transactions from that window and the unauthorized ZANO and fUSD that entered circulation. However, payments already completed on other blockchains cannot be undone, limiting how far the recovery can reverse real-world settlement.

Zano will handle remediation for affected parties through a reimbursement and claims process, though details have not yet been published. The fix requires coordinated adoption by infrastructure operators and service providers, including exchanges and other third parties that integrate with Zano.
