# Harmony review: Trust Score 38/100 (Caution)

Harmony (ONE): a 2026 mint exploit and a reported plan to shut its own chain have badly hurt trust

Harmony launched its mainnet in 2019 and, by users' accounts, delivered fast, cheap transactions. Its record since then is troubled. A 2022 bridge hack reportedly took about $100M, and in August 2026 TechTimes reported an unauthorized mint of roughly 4 billion ONE (about 26% of supply). In September 2026 CoinDesk and The Defiant reported that Harmony proposed shutting down its own Layer-1 and moving ONE to Ethereum. We found no regulator warnings or lawsuits naming Harmony in the sources provided, but the notes also give no clear team roster, legal entity or official fundraising total, and ONE hit an all-time low in the 2026 incident.
