Live quotes compared across 30+ bridges and DEXs. Non-custodial — your wallet signs every transaction.
About this route
Arbitrum One. The largest Ethereum rollup by value locked, and the default home for perpetuals and other trading-heavy protocols. Fees are a fraction of mainnet while keeping Ethereum security.
Base. Coinbase's OP Stack rollup, and the chain most new consumer and social apps launch on. Its link to a major exchange makes it a common first stop for people arriving from fiat.
Arbitrum has by far the deepest third-party bridge liquidity of any L2, so large transfers here usually quote a tighter rate than to smaller rollups.
Base has direct Coinbase deposit and withdrawal support, so it is often cheaper to move funds via the exchange than via a bridge — worth checking before you pay bridge fees.
Common questions

Is Bospora custodial?
No. Bospora is an interface to the LI.FI routing API. Funds move directly from your wallet to the bridge contract, and every transaction is signed by you.
