svgnft
A helper library for generating fully on-chain NFTs (ERC721) on Ethereum.
Being on-chain is fun!
Example
See example/. Override tokenUri with something like:
function tokenURI(uint256 tokenId) public view virtual override returns (string memory) {
string memory name = string(abi.encodePacked("MyToken #", tokenId.toString()));
string memory description = "An example SVG-based, fully on-chain NFT";
string memory svg = '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1000 1000"><circle cx={500} cy={500} r={400} fill="papayawhip" /></svg>';
return SVG721.metadata(name, description, svg);
}That's it!
