“Programmable NFTs” are a new standard for Solana NFTs introduced by Metaplex to enable the enforcement of creator royalties. Programmable NFTs allow creators to decide which protocols their NFTs are allowed to interact with through the use of allow and deny lists. Creators can prevent their collections from trading on marketplaces that do not enable royalties.
Most marketplaces (including Magic Eden), wallets, and protocols support programmable NFTs. It will be the dominant standard for royalty enforcement on Solana. Metaplex began allowing NFT collections to upgrade to this new token standard on February 6th 2023.
