ERC7548: Open IP protocol that enables remixing of ERC721 NFTs

The ERC-7548 draft proposes a standardized way to create new intellectual property by remixing multiple existing NFTs, with each IP represented as an NFT and its relationships recorded publicly on-chain. It extends the ERC-721 standard through three modules: a remix module for minting combos from several NFTs (ERC-721 or ERC-1155), a license module that lets NFT holders grant others permission to use their NFTs in remixing, and a singleton network module that tracks parent and child relationships. The authors, Combo, Saitama, CT29 and Luigi, describe the goal as letting creators register, license and monetize content globally. The security section flags ownership and access controls, reentrancy risks, and high gas costs as concerns. The status is listed as Draft.
