JUST IN: Harmony Exploited in Unauthorized Mint of 4 Billion ONE Harmony, a Layer 1 blockchain launched in 2019, said it is working with exchanges to stop and freeze funds following a suspected exploit, while developing a patch and evaluating rollback options. On-chain analyst Juiceberg reported that roughly 4 billion ONE, equivalent to about 26% of the token supply, was minted without authorization via empty blocks, with around 2.8 billion ONE quickly routed to exchanges as the token price plunged. Harmony has yet to disclose the root cause or confirm the amount involved. The network previously suffered a roughly $100 million exploit of its Horizon Bridge in 2022.

@WuBlockchain interesting development

AMk.Crypto 🧢 @leeky_k_crypt ·

@WuBlockchain 4B ONE minted out of nowhere that's a massive exploit.

@WuBlockchain That is a massive amount of supply to flood the market with. Absolutely brutal for holders.

@WuBlockchain If the exploit is confirmed, expect Harmony to freeze affected funds and possibly roll back transactions; investors should stay cautious until official updates.

@WuBlockchain An unauthorized supply increase can severely damage market confidence. Strong mint controls and transparent monitoring are critical for chain security

Tushant Suneja @tushant_suneja ·

@WuBlockchain 4 billion one tokens is roughly 15% of the total supply, the real challenge now is to freeze and recover those funds without causing a bank run on harmony's ecosystem

@WuBlockchain 26% of supply minted out of thin air and they still havent confirmed the root cause thats the part that stings

Rock1988 @cmaDxB ·

@WuBlockchain This is second time, Harmony also exploited before I think in 2022

django @oxngon ·

@WuBlockchain This is not harmony's first video. They got the bridge exploit that fucked many people. Not to mention the sickening corruption they pulled with the 10000 DAOs saga.

@WuBlockchain Harmonising the hacks all over..

Ovi @ogenesisc ·

@WuBlockchain This is why supply integrity is infrastructure, not just tokenomics. Once unauthorized minting reaches exchanges, the damage compounds incredibly fast.

@WuBlockchain plz no more harm money

Confirmed by Harmony and multiple reports: Unauthorized mint of ~4B ONE (~26% of supply) via empty blocks, with ~2.8B moved to exchanges. Team working to freeze funds, patching, and weighing rollback options. Price hit hard. Another reminder of L1 security risks (after the 2022 Horizon Bridge incident). Sources: theblock.co/news/defi/2026-08-… coindesk.com/markets/2026/08/1… @harmonyprotocol updates Stay safe out there. #ONE #Harmony

@WuBlockchain 2022: Horizon Bridge was hacked, resulting in a loss of nearly $100 million. December 2023: A staking system bug caused approximately 146.3 million ONE to be unauthorizedly minted (involving around 74 addresses). x.com/coinminutes_en/status/20…

比特丛林 BitJungle @BitJungle_team ·

@WuBlockchain The key issue is not only how many tokens were minted, but how many reached the market. The minted amount, exchange deposits and actual sales should be verified separately.x.com/BitJungle_team/status/20…

BlockWatchdog @BlockWatchdog ·

@WuBlockchain That 2.8bn is one transaction — 0xed2f…08eb, 74 seconds after it was credited. The same attack moved 2,385,000,000,000 ONE 4.5 hours later, in 106 seconds, across 477 addresses. x.com/BlockWatchdog/status/208…

@WuBlockchain This is a stark reminder that L1 security remains the most critical hurdle for mass adoption. The recovery phase, while painful, always drives necessary improvements in consensus safety mechanisms. Keep learning from these events; they are foundational lessons for every build.

@WuBlockchain The RCA will be interesting to read as it minted a quarter of the supply.

IggorLeo🐻‍❄️ @Asiootus11 ·

@WuBlockchain Binance should delist $ONE . This protocol is ☠️

Byrrgis @byrrgis ·

@WuBlockchain 26% of the supply appearing out of nowhere is about as bad as it gets. 😬

@WuBlockchain The price took a wild nosedive while the team scrambled to slam the brakes. Crypto drama never sleeps, right?

@WuBlockchain i suspect foul play and insider work

Alex @alexzed57 ·

@WuBlockchain Minting 26% of supply out of nowhere is a brutal hit to confidence.
