Fascinating! So can a single collection exist on multiple chains? Does bridging it from ETH to Base burn the ETH version so it won’t be double-counted?

Yes - exactly! The NFT can be bridged to multiple Superchain rollups. We currently support /optimism and /base but in the near future will support additional networks like /zora. The NFT is more "locked" than "burned" because the NFT can also be transferred back to Ethereum.

Generally royalties aren' handled at the smart contract level and enforced at the trading platform level i.e. OpenSea. In the coming weeks we're going to connect with these types of platforms to figure out the best way to handle these multi-chain NFTS. The tokenURI is handled via the EIP-681 standard.

The Optimism repo is the best place to see how the tokenURI is handled. https://github.com/ethereum-optimism/optimism/blob/6c0d75dbe39115fc6fbef134732748e11c4802b7/packages/contracts-bedrock/src/universal/OptimismMintableERC721.sol#L62
