OpenSea Chief Technology Officer Chris Maddern said the marketplace was not affected by security incidents involving Magic Eden and Limit Break, with its systems and smart contracts operating normally. The platform will display warning banners directing users to links where they can revoke authorizations. More than 3,000 NFTs have been marked as stolen and blocked from trading. Known affected ERC-721 NFTs, a standard for unique digital collectibles, have been flagged, and newly identified exploited NFTs will also be marked automatically to prevent attackers from receiving relevant offers. OpenSea said it will continue helping reduce the impact of the industry security incident on users.
