Quote Base to ArbitrumHow routing works

Across two EVM rollups

The route begins on Base and delivers the selected asset on Arbitrum. Betelgeuse uses the current provider response to show expected output before execution.

Even though the same address can exist on both networks, verify the network names and token contracts.

Gas and completion

ETH pays the source transaction fee on Base. After receiving on Arbitrum, ETH is also required for later Arbitrum transactions.

  • Confirm Base as pay network.
  • Confirm Arbitrum as receive network.
  • Check route status until destination delivery.

Common questions

Before you continue

Do Base and Arbitrum both use ETH for gas?

Yes. ETH is used for network fees on both networks.

Can I use the same wallet address?

Both are EVM networks, so the address format is the same, but you should still verify ownership and the selected destination network.

Why might the route contain more than one step?

Cross-chain delivery can require a source swap, a bridge and a destination swap.
