On June 15, the full-chain NFT protocol Holograph Protocol released an exploit update. A former contractor used the vulnerability to mint an additional 1 billion HLG tokens on Mantle, causing the protocol to be temporarily blocked. The malicious actor has had his accounts frozen on multiple exchanges, and at least 200 million of the additional 1 billion HLG tokens have been frozen. At the same time, the exchange has also temporarily stopped all deposit and withdrawal transactions of HLG tokens. A third-party audit will be conducted next, and the multi-chain tokenization infrastructure and applications will continue to be promoted.
