Is there a canonical bridge to move NFTs from mainnet to @base?

you can use the native bridge for that, though there's not yet a UI for it

@wilsoncusack @bayardo.eth do you know what the functions are?

we welcome mainnet NFTs

Haven’t used, but is here https://etherscan.io/address/0x608d94945A64503E642E6370Ec598e519a2C1E53#writeProxyContract

Is there is a public Github repo wgere I could check out the unit tests and general flow of the contracts?

Could probably whip something up this weekend if I had little more context on how everything is expected to work.

Maybe start here? https://github.com/ethereum-optimism/optimism/blob/develop/packages/contracts-bedrock/test/L1/L1ERC721Bridge.t.sol

Perfect - thank you. Looks like the L2 NFT needs to inherit OptimismMintableERC721.sol

By any chance do you know if there is factory or registry contract that already exists for this?

If not maybe I should write a CREATE2 factory that hashes the L1 NFT address and L2 chainId to create a deterministic L2 NFT contract?
