The token list is display verified Superchain NFT contracts in the Based Bridge Application.

The District Labs, Inc. team is responsible for maintaining the token list and adding new NFT contracts to the list.

But we welcome anyone to submit new NFT contracts to the list. To add a new token to the list, you need to open a pull request adding the NFT contract address from the L1 network and the corresponding bridged contract address on the L2 network to the token list.
