Cardinal, the Solana ecological NFT infrastructure agreement, announced that it will gradually close the agreement because it is difficult for the project to find products suitable for the market. The team stated that the protocol will always be open-source and accessible to all. It is recommended that all users who deposit assets in its system withdraw assets manually within two months, after which all remaining deposits will be forced to be withdrawn and returned to depositors. Additionally, all new deposit instructions and other features in the protocol will be disabled starting July 19. Foresight News noted that Cardinal provides leasing, pledge and other services for NFT, and completed a $4.4 million seed round of financing in July 2022, led by Protagonist and Solana Ventures, with participation from Animoca Brands, Alameda Research, Delphi Digital and CMS Holdings .
