@rasguy92 The response from @mmt is not accurate. There are many subtle differences to consider when bridging NFTs vs ERC20s, but it’s important to understand that you’ll need a custom gateway for ERC721 bridging. You’ll also need to modify the “destination” chain’s contract (you can’t simply deploy the same contract to both layers as the mint/burn functionality is fundamentally different). We are working on providing better examples of this, but in the meantime, please refer to this talk by our own Daniel Goldman, which may set you on the right path:
