Solana’s Cardinal protocol is winding down operations due to economic conditions, nearly a year after raising $4.4 million to improve nonfungible tokens (NFT) utility. According to an announcement on Twitter, withdrawals should be made by Aug. 26.

Cardinal Labs was an infrastructure provider dedicated to supporting NFT use cases on the network by offering protocols and software development kits (SDKs) for staking, rentals, subscriptions, royalties and trading.
