Design

Picasarts has 1 governance contract (Hub) and 3 feature contracts (Marketplace, Loan and Rental). For handle logic of feature contracts and futher extending contract, this is design of them:

Those also use same a NFT standard contract called PNFT extend from ERC-721, ERC-2981 and ERC-4907. This is not required, you can create new PNFT contract by Hub or just import simple ERC-721 contract that extend Ownable contract but I encourage you use this contract for able using full product features.
