[frangio]

Generally all of the images are generated beforehand and later distributed. It is a challenge how to distribute them randomly in a way that is not easy to game. More discussion here:

Are NFT projects doing starting index randomization and provenance wrong or is it just me?

Hi, There is a pattern in many PFP projects where the tokenURI does something like: function tokenURI(uint256 tokenId) public view virtual override returns (string memory) { require(_exists(tokenId), "ERC721Metadata: URI query for nonexistent token"); string memory baseURI = _baseURI(); return bytes(baseURI).length > 0 ? string(abi.encodePacked(baseURI, tokenId.toString())) : ""; } Where the baseURI is some IPFS directory. This is the standard implementation from Ope…
