Harmony's ONE Token Plummets 37% Following Unauthorized Minting of 4 Billion Tokens

Key Facts

In a move highlighting the persistent security vulnerabilities within the crypto sector, Harmony's ONE token experienced a sharp 37% price collapse. The crash followed an exploit where an attacker unauthorizedly minted 4 billion tokens, leading to massive dilution and market panic. According to reports, the Harmony team is now evaluating a potential network rollback to undo the attack and invalidate the subsequent transactions.

This incident places significant pressure on investor confidence in Layer-1 protocols, as the unauthorized minting raises fundamental questions about network security. Per analyst data, the proposed rollback is a controversial measure in the blockchain community as it challenges the principle of immutability; however, the scale of the 4-billion-token exploit may necessitate such action to mitigate further financial fallout.

Based on market data as of August 12, 2026, specific closing prices for ONE are currently unavailable, though the qualitative outlook remains bearish. Traders should closely monitor official updates regarding the network rollback, alongside broader market catalysts such as the U.S. Initial Jobless Claims scheduled for August 6, 2026, which may influence overall risk sentiment.
