Quote Base to OptimismHow routing works

Compare the complete route

The expected output accounts for the provider route available at quote time. A cross-chain trade can include multiple steps even when both endpoints use EVM wallets.

Use the destination amount and route details—not a token spot price alone—to evaluate the result.

Prepare ETH for gas

ETH pays network fees on Base and Optimism. The source wallet needs ETH on Base to begin the route.

  • Select the correct source token contract.
  • Verify Optimism as the destination.
  • Track completion after signing.
