On June 15, Holograph Protocol, a full-chain NFT protocol, announced a vulnerability exploit update, where a former contractor exploited the vulnerability to mint an additional 1 billion HLG tokens on Mantle, leading to the temporary suspension of the protocol. The malicious actor's accounts have been frozen on multiple exchanges, and at least 200 million of the extra minted 1 billion HLG tokens have been frozen. Meanwhile, exchanges have temporarily halted all HLG token transactions. Third-party audits will be conducted next, and the development of multi-chain tokenization infrastructure and applications will continue.
