Learn how to set up and receive your royalties on NFT Marketplaces.
EIP-2981 Royalty Standard Smart Contracts created with NiftyKit (as of April 3, 2022) use the EIP-2981 Royalty Standard. EIP-2981 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.
OpenSea's Operator Filter are also baked in within the smart contract.

Opensea currently doesn't support the EIP-2981 standard. Royalty Percentages need to be set manually on Opensea. Navigate to the "Collection Editor" on Opensea and adjust the Percentage fee field under Royalties, as shown below.
