Quote Arbitrum to BaseHow routing works

Route discovery and execution

Betelgeuse requests current route options for the selected pair and displays the expected Base output. The connected wallet remains responsible for source approval.

Cross-chain status should be followed through destination delivery, not only the first source-chain confirmation.

Before signing

Check the source balance, ETH available for gas and the intended Base receiving address.

  • Confirm Arbitrum is the source.
  • Confirm Base is the destination.
  • Review expected and minimum output.
  • Wait for destination completion.

Common questions

Before you continue

Is source confirmation the end of the route?

No. A cross-chain route is complete only after the provider reports destination delivery.

Which asset pays Arbitrum gas?

ETH pays the source network fee on Arbitrum.

Can route timing vary?

Yes. Timing varies with the bridge path, source and destination confirmation, and provider conditions.
