Making it slightly easier to create fully on-chain SVG-based NFTs.

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!
