The issue, linked to third-party tooling, has seen OpenSea, a leading NFT marketplace, swiftly assuring its users of their platform’s safety, as reported by OpenSea on X. Their SeaDrop contract, as confirmed by business development lead Will Brooke, remains unaffected by this vulnerability. “Confirmed—does not affect ERC721SeaDrop,” Brooke stated, highlighting OpenSea’s commitment to user protection.

In response, thirdweb has launched a mitigation website, providing a list of affected contracts and detailed instructions for users to mitigate the risks. “The mitigation steps will involve locking the contract, taking a snapshot, and migrating to a new contract without the known vulnerability,” Thirdweb advised. The discovery has caused widespread concern in the web3 community, with stakeholders such as Sean Bonner, a project creator, expressing frustration over the lack of detailed information.

In reaction to this unfolding situation, major marketplaces such as Rarible and OpenSea have been proactive in reassuring and guiding their users.
