ERC2981 is a standardized way to retrieve royalty payment information for non-fungible tokens (NFTs) to enable universal support for royalty payments across all NFT marketplaces and ecosystem participants.
It is not supported by legacy marketplaces like OpenSea where you need to have a contract URI for royalties. In this video I explain how to set royalties for OpenSea and other such legacy marketplaces, and add ERC2981 to your NFT Smart Contract so it can let all supported marketplaces know how to process the royalties.
