NFT marketplace OpenSea says creators can now set and enforce their own creator earnings on its platform using ERC721-C. ERC721-C enables creators to implement programmable and executable creator earnings on-chain, allowing creators to implement custom logic in their collections. OpenSea has launched a tool under OpenSea Creator Studio to help creators deploy ERC721-C contracts.

Two weeks ago, OpenSea launched a new version of the OpenSea Market Protocol, Seaport v1.6, and introduced the concept of Seaport Hooks. Seaport Hooks allow creators to set conditions that need to be met before transferring NFTs in their collections.
