iNFT – an onchain NFT for Idena identities

This is a fully onchain ERC721-compatible NFT that can be generated by validated identities in Idena.

You can use it here: https://inft.bus.bz

Since original art is not my strong suit, this is mostly a proof-of-concept for a generative NFT on Idena that could be used as a basis for another project in the future.

Features

• Fully onchain art generation and storage
• Ability to choose a different art contract for each token (though there's only one contract now)
• Almost full compatibility with ERC721 standard (with Metadata and Enumerable extensions)
• If you own an iNFT of another identity then you'll be able to regenerate it as long as that identity stays validated
• Attributes in token metadata created by the art contract (like identity status and age)

Building

1. Build irc721 contract: yarn asb
2. Build nft_generator contract: yarn asb
3. Set the deployed art generator as approved using the setApprovedGenerator method
4. Deploy a Cloudflare Worker for authentication: frontend/worker.js
5. Specify contract addresses and URLs in frontend/src/config.js
6. Build frontend: npm run build

Testing

Currently tests require a modified contract runner that supports sending transactions from different addresses. I'll try to upstream these changes because I believe they're essential for testing.
