OpenSea planned upgrade stalls as phishing attack targets NFT migration By Cointelegraph

Just yesterday, OpenSea announced a smart contract upgrade, which requires users to migrate their listed NFTs from (ETH) blockchain to a new smart contract. As a direct result of the upgrade, users that don’t migrate over from Ethereum risk losing their old, inactive listings — which currently require no gas fees for migration.

Major nonfungible token (NFT) marketplace OpenSea has reportedly fallen victim to an ongoing phishing attack within hours after announcing a week-long planned upgrade to delist inactive NFTs on the platform.
