Harmony to Roll Back ONE Ledger to August 11, 2026

Harmony Protocol said it will roll back its network following an anomalous ONE token minting incident, resetting Shard 0 to block 92,730,034 and Shard 1 to block 94,978,278, both aligned with 23:25:37 UTC on Aug. 11, 2026, according to Huoxing Finance. Validators will switch to replacement databases from those block heights and re-produce subsequent blocks starting at 92,730,035 on Shard 0 and 94,978,279 on Shard 1. Harmony said the first confirmed forged mint occurred at Shard 0 block 92,730,036, and the rollback point was set one block earlier as a safety buffer. The team said it reviewed multiple recovery options, including targeted token burns, blacklisting, selective transaction replay, token migration and a direct database rollback. It concluded these approaches could impact unrelated funds or introduce chain state inconsistencies, and opted for a fixed rollback window. Harmony disclosed that a single forged-mint wallet attempted 534 transfers of 50 billion ONE each over 106 seconds. Of those, 477 transactions succeeded, moving a total of 2.385 trillion ONE. The team said it has traced more than 99.9% of the forged ONE pathways, while noting that "traceability to a wallet or cluster" does not mean specific individuals have been identified or that all related funds can be safely destroyed. Harmony also said it has fully archived Shard 0 from block 92,730,035 through 92,871,662, covering 141,628 consecutive blocks, 109,126 standard transactions and 315 staking transactions. All blocks and standard transactions after the rollback checkpoint will be discarded. The team said it is working with exchanges, cross-chain bridges and law enforcement to assess impacts and determine next steps. Harmony added that an independent third-party security firm has reviewed the incident and verified the forged minting discovery and the primary fund flows. Validators are required to execute the rollback using the official recovery procedure.
