How It Works

Pure SVG on-chain

Your pixel art is encoded as SVG directly in the smart contract. Each trait combination produces a unique, deterministic image that lives forever on the blockchain.

  • No external dependencies
  • Immutable storage
  • Gas-optimized encoding
  • Instant rendering
tokenURI.sol
function tokenURI(uint256 id)
  public view returns (string memory) {

  bytes memory svg = abi.encodePacked(
    '<svg viewBox="0 0 64 64">',
    _generatePixels(id),
    '</svg>'
  );

  return string(abi.encodePacked(
    'data:application/json;base64,',
    Base64.encode(metadata)
  ));
}
