NFT trading platform OpenSea announced that it will fully take down version OS1 on June 16, and its new version OS2 will no longer support features such as Deals, English auctions, testnet support, and shopping cart. The platform explained that these features had insufficient usage and that 'transaction negotiation' had compatibility issues with the ERC 721-C royalty enforcement contract. Some users expressed dissatisfaction, believing that the removal of 'Deals' would increase the risk of fraud. This feature was launched in July 2023, allowing users to customize NFT exchange arrangements. (Blockworks)
