How can i create a new contract ERC-721 standard?

Hi friends, how can i use ERC721 eth standard to generate nft tokens in Holochain?
I need to generate NTF (not fungible tokens) for a website that i am creating. this website is similar to Opensea.io, but with holochain for the managment of the contracts.

Are NFT’s compatible with Holochain?

It seems to me that you could implement something really similar to NFTs with something akin to a chain of custody. Here I put together a workshop describing the necessary steps to do that: https://holochain-gym.github.io/workshops/workshop-1/design/.

It’s not that holochain is compatible or not with NFTs, they are just one use case of validation rules that can be implemented in holochain.
