Humanity Protocol price plunges 83% as $30M key breach widens

Humanity Protocol’s H token lost more than 80% of its value on June 9 after attackers drained wallets linked to the project. 

The team confirmed that a private key belonging to a Humanity Foundation member had been compromised.

Humanity Protocol runs a zkEVM-based identity network that uses zero-knowledge proofs and palm biometrics to verify unique users without exposing their full personal data to large centralized identity databases.

Humanity founder confirms private key compromise

“We’ve detected a security incident involving the compromise of private keys belonging to a member of the Humanity Foundation,” founder and CEO Terence Kwok said. He did not identify the affected member or explain how the keys were exposed.

Kwok told users to avoid the Humanity bridge and all liquidity pools until the team confirms they are safe. He said Humanity was working with security specialists and exchange partners. No recovery plan, reimbursement terms, or full technical report had been published at the time of writing.

On-chain analyst Specter first reported that more than 17 wallets holding H had been drained. The analyst said the wallets were linked to, or had interacted with, Humanity Protocol. Early estimates placed losses near $19 million before later trackers raised the total above $30 million.

Arkham-linked tracking and other on-chain reports showed the attacker selling H and converting part of the proceeds into Ethereum. Specter wrote on his Telegram that about $23.7 million had been swapped into ETH, while roughly $7.9 million remained in H. 

Blockaid monitoring later claimed the attacker gained proxy administrator rights over H on BNB Smart Chain and minted 100 million tokens. Humanity had not confirmed that report.

H price wipes out its June rally

According to crypto.news data, the Humanity Protocol (H) traded near $0.123, down about 83% over 24 hours. The token traded between roughly $0.073 and $0.731, while daily volume climbed above $605 million. Its market value fell to about $222 million during the sell-off.

H reached a record high near $0.844 on June 2 before the breach erased most of that advance. The drop also came before a scheduled June 25 token release under Humanity Foundation’s revised investor vesting plan. 

As previously reported by crypto.news, some early backers chose a discounted immediate unlock instead of a longer vesting schedule. There is no public evidence linking that planned release to the attack.

The incident adds to a series of private key and privileged-access failures across crypto projects in 2026. Separate crypto.news reporting found that a suspected key compromise allowed an attacker to mint StablR tokens and extract about $2.8 million in May. Humanity’s team has asked users to wait for further confirmation before using affected services.
