Top claims

▪The unauthorized minting of 4 billion ONE tokens on August 12, 2026, represented an increase of about 26% against the existing supply of roughly 15 billion ONE tokens.
▪Following the August 12, 2026 exploit, Harmony paused its token bridge and requested cryptocurrency exchanges to freeze funds traced to four specific wallet addresses linked to the incident.
▪A potential blockchain rollback would return the Harmony network to its state before the August 12, 2026 exploit, effectively removing subsequent transactions from the blockchain's history.
