To ensure your royalties get distributed to you and any of your collaborators, you must configure your royalties on chain.

Coinbase NFT will honor on-chain royalties using Manifold’s Royalty Registry. Creators can either configure on-chain royalties through your smart contract (if using a token spec that supports royalties like EIP-2981) or use Manifold’s Royalty Registry configuration to set an on-chain override if not using a token spec that supports royalties. 

Once you’ve added on-chain royalties, secondary sales of your NFT on Coinbase NFT will honor that royalty.
