NFT trading platform OpenSea announced that it will fully discontinue the OS1 version on June 16th, and its new version OS2 will no longer support features such as Deals, British auctions, testnet support, and shopping carts. The platform explained that these features have insufficient usage and there are compatibility issues between "transaction bargaining" and the mandatory royalty contract of ERC 721-C. Some users expressed dissatisfaction with this, believing that canceling "Deals" would increase the risk of fraud. This feature will be launched in July 2023, allowing users to customize NFT exchange schemes. （Blockworks） https://www. (wublock123.com)/index.php? m=content&c=index&a=show&catid=6&id=43899
