The “Operation Based Bridge” mission is focused on catalyzing the mass migration of NFTs from Ethereum Mainnet to the Superchain Ecosystem: Optimism, Base, Zora, etc… using a Based Bridge (BB) token. Problem Each Optimism rollup includes a canonical ERC721 bridging smart contract. But to date there has been very little activity on these canonical smart contracts: Optimism, Base and Zora all have little to no transactions originating to/from these smart contracts. But... why? First, no application exists that makes bridging NFT easy for the average user.
