Overview
Bridge quote, cross-chain. Cheapest route to move tokens between chains (Ethereum to Base, Arbitrum to Solana…) across 20+ bridges via LI.FI: amount received, minimum, USD values, gas, bridge fees, total cost in percent, estimated time, steps and approval address; with fromAddress, the unsigned transaction to sign. Swaps on either side are included when the tokens differ. A quote only: nothing is signed or sent. Use before an agent moves funds across chains.
