Harmony's ONE token lost a quarter of its value in a single day after an attacker allegedly minted 4 billion new tokens. The project behind the cryptocurrency is now working with exchanges to freeze the funds and is preparing a software fix to close the hole.
The alleged mint
The trouble started when reports surfaced that a malicious actor had created billions of ONE tokens out of thin air. The minting flooded the supply, and the price reacted immediately. ONE dropped 26% in the hours that followed, erasing a significant chunk of the token's market value.
Details on how the attacker pulled it off are still thin. The project hasn't released a full post-mortem, and it's not clear whether the mint exploited a vulnerability in the token's smart contract or something else. What is known is that 4 billion tokens were created, and that's a lot for a token with a relatively small circulating supply.
Freeze and fix
Harmony is working with exchanges to freeze the funds. That's a practical step: if the minted tokens are still sitting in accounts, freezing them could prevent the attacker from cashing out. The project is also preparing a software fix, which would presumably patch the vulnerability and stop any further unauthorized minting.
The freeze is a collaborative effort, but it's not a guarantee. Some of the tokens may have already been sold or moved to other wallets. The longer the freeze takes, the more likely the attacker has found a way to launder the funds.
Impact on holders
For regular holders, the immediate impact is a steep loss. A 26% drop in a day is brutal, and it's the kind of move that can shake confidence in a project. The freeze might help recover some of the minted tokens, but it won't bring back the value that was lost in the sell-off.
The bigger question is what this does to trust. Harmony has been around for a while, and ONE is a known token. A minting exploit is a serious security failure, and it's the kind of thing that makes people think twice about holding.
The software fix is the immediate priority. Harmony is preparing it, but there's no word on when it will be ready. Until it's deployed, the vulnerability that allowed the minting remains open. The freeze with exchanges is ongoing, and it's unclear how many of the 4 billion tokens have been recovered or sold.
The project hasn't said whether it will pursue legal action against the attacker. For now, the focus is on containing the damage and preventing another mint. The token's price is down, and the market is watching to see how Harmony responds.
