Humanity Protocol’s H token plunged more than 80% on Tuesday after attackers stole the private keys behind the project and drained more than $30 million, the latest in a year of cryptocurrency thefts that go after keys rather than codes.
Around 17 wallets linked to the project were emptied, with losses exceeding $32 million and continuing to rise, according to on-chain data evaluated by CoinDesk.
The thief has been selling the stolen H for ether and minted another 100 million H, worth around $11 million, on the BNB chain, blockchain data shows, pointing to greater selling pressure in the future.
H fell from about $0.67 to around $0.13 and briefly touched $0.05, an intraday drop of about 90%.
Humanity confirmed the breach, with founder Terence Kwok saying that attackers had compromised the private keys, the secret codes that control crypto wallets, of a member of the Humanity Foundation.
The project urged users to stop touching its bridge, the tool that moves tokens between blockchains, and its liquidity pools until the problem is contained, and said it was working with security companies and exchange partners.
Humanity Protocol is a decentralized identity project that uses palm scanning biometrics and zero-knowledge cryptography to allow people to prove they are human without revealing personal data, positioning itself as a rival to Sam Altman’s Worldcoin.
The hack fits the dominant pattern of 2026, in which the biggest losses come from stolen keys rather than faulty codes. Solana exchange Drift lost around $285 million in April after attackers seized an administrative key, and Kelp DAO lost around $292 million the same month through a single validator bridge.
H last traded around $0.13, down around 82% on the day, with the theft still ongoing.
