Harmony Rolls Back Chain to Contain Forged Minting Exploit

Harmony said it has updated its rollback and recovery plan following a forged minting incident. According to ME News, the network will roll back to block 92,730,034 on Shard 0 and block 94,978,278 on Shard 1 as the recovery point, with both blocks timestamped Aug. 12, 2026, 07:25:37. Validators will switch to the corresponding replacement databases, and the chain will resume block production from heights 92,730,035 and 94,978,279. The team said it assessed several alternatives—including targeted burns, blacklisting, selective replay, and token migration—but rejected them because they could affect unrelated funds or fail to fully remove the forged states. Harmony ultimately opted to replace the databases. On-chain tracking indicates the attacker's forged minting wallet attempted 534 transfers within 106 seconds, successfully moving 2.385 trillion ONE tokens. The team said more than 99.9% of the stolen funds have been traced to related wallets or service providers. Harmony said it is working with exchanges, cross-chain bridges, and law enforcement agencies to investigate the incident, and that independent third-party security firms have verified the findings. The project is also coordinating with exchanges and bridges to assess the impact and develop a loss-minimization plan. Validators are required to complete the upgrade in line with the official operational checklist. (Source: Foresight News)
