Harmony's ONE token plunged 26% after an apparent exploit flooded the market with roughly 4 billion newly minted tokens — a figure equal to about a quarter of the network's circulating supply — sparking fresh concerns over the security of the blockchain protocol.
What Happened
The sharp sell-off followed reports that an attacker managed to mint billions of ONE tokens, dramatically inflating the supply and driving the price sharply lower. The scale of the alleged minting, equivalent to roughly 25% of the tokens already in circulation, rattled holders and traders who rushed to exit positions.
Harmony acknowledged the incident during Asian morning hours, saying it had detected the problem and was coordinating a response. The team indicated it is working closely with cryptocurrency exchanges in an effort to freeze the affected funds before they can be liquidated or moved across platforms.
A flood of freshly minted tokens equal to a quarter of the supply sent ONE tumbling and holders scrambling for the exits.
The Response
Beyond the exchange coordination, Harmony said it is preparing a software fix intended to address the vulnerability that made the alleged exploit possible. Freezing funds through exchange partnerships is a common early step in responding to such incidents, as it can prevent an attacker from cashing out illicitly obtained tokens.
The steep price drop underscores how vulnerable smaller-cap tokens can be to sudden supply shocks, particularly when an exploit introduces a large volume of new coins into an already thin market.
Key points from the developing situation:
- ONE fell roughly 26% following the apparent attack.
- Around 4 billion tokens were allegedly minted, about a quarter of circulating supply.
- Harmony is coordinating with exchanges to freeze funds.
- A software patch is being prepared to close the vulnerability.
Harmony has faced security challenges before, and this latest episode is likely to renew scrutiny of the project's infrastructure and safeguards. As the team races to contain the damage, investors will be watching closely to see whether the frozen funds and forthcoming fix can restore confidence in the network.
