Coinfomania and CryptoSlate both report a Harmony ONE exploit with figures of roughly 4 billion tokens minted and 2.8 billion reaching exchanges, but disagree on whether Harmony itself confirmed those numbers.
What all sources agree on
- Harmony released emergency validator patch v2026.1.1 to address the exploit.
- The exploit involved unauthorized minting of ONE tokens.
- Figures of approximately 4 billion ONE minted and 2.8 billion ONE reaching exchanges are cited in both reports.
- Harmony is considering a potential blockchain rollback but has not announced one will occur.
- Harmony paused bridge.harmony.one during its response.
Where the reports disagree
1Whether Harmony confirmed the 4B minted / 2.8B moved-to-exchanges figures
Harmony has confirmed a significant exploit involving the unauthorized minting of approximately 4 billion ONE tokens, equivalent to around 26% of its total supply.
Onchain researcher Juiceberg estimated that roughly 4 billion ONE, equal to about 26% of the supply figure used in the post, had been minted without authorization. Juiceberg also estimated that 2.8 billion ONE had reached exchanges. Harmony has not independently confirmed those figures.
What would settle it: Harmony's official statement or on-chain data disclosing the exact amount minted and moved to exchanges.
2What Harmony's own notice disclosed about the amount minted
As of now, 2.8 billion ONE tokens have reportedly been moved to exchanges, while only 115 million remain on-chain.
The notice confirms that minting occurred but does not disclose the amount.
What would settle it: Harmony's published validator notice or subsequent official disclosure specifying the minted amount.
What to make of it
Treat the existence of the exploit and the v2026.1.1 patch as established, but the specific figures of 4 billion minted and 2.8 billion moved to exchanges remain, per CryptoSlate, an outside researcher's estimate not yet confirmed by Harmony; wait for an official Harmony statement before treating those numbers as fact.
