A whitehat moved 3,832 non-fungible tokens from hundreds of wallets on Friday amid concerns about a vulnerability involving NFT marketplace Magic Eden. Community member Cirrus flagged the activity, noting that transactions appeared as sales through the platform and advising holders to revoke permissions as a precaution. Shortly after, Yuga Labs’ pseudonymous vice president of blockchain, 0xQuit, confirmed the transfers were part of a white-hat operation. He stated that the NFTs held in the receiving wallet are safe and will be returned once they are no longer at risk.

Yuga Labs CEO Michael Figge indicated that a vulnerability was discovered a few hours earlier and promised further information soon. This incident follows similar rescue efforts by 0xQuit, who helped recover 68 NFTs worth more than $500,000 after an exploit hit Flooring Protocol in June. As of publication, Magic Eden has not publicly confirmed that its contracts were exploited, and Cointelegraph had not received a response to requests for comment.
