ERC-6551 Token Bound Accounts

(aka how NFTs can own assets). Every NFT has it owns wallet

The ERC-6551 standard specifies how an NFT can "own" other assets. Essentially, the NFT owns a variation of a "smart wallet" that itself is the owner of other assets.

If you want to bring together your knowledge of proxies, assembly optimization, NFTs, and several other ERCs, ERC-6551 will do that for you!

The interace 

interface IERC6551Registry {
    function createAccount(
    address implementation,
    uint256 chainId,
    address tokenContract,
    uint256 tokenId,
    uint256 salt,
    bytes calldata initData
    ) external returns (address) ;


    function account(
    address implementation,
    uint256 chainId,
    address tokenContract,
    uint256 tokenId,
    uint256 salt
    ) external view returns (address);
}
