Base Bridge is the canonical bridge between Ethereum and Base, the OP Stack rollup operated by Coinbase. ETH and ERC-20s deposited on Ethereum become spendable on Base in minutes; withdrawals back to Ethereum follow the standard seven-day OP Stack fraud-proof window.
As a canonical bridge, Base Bridge inherits its security from the Base rollup contracts on Ethereum rather than from a separate validator set. Most of the value bridged into Base sits in this contract, making it the system’s largest TVL surface.
