Optimism

Swap tokens on Optimism

Compare an available Optimism route, inspect the receive estimate and confirm from your own wallet. ETH is required for network fees.

Quote before execution

Betelgeuse separates route discovery from wallet approval. You can inspect the expected output and route state before sending a transaction.

A quote is time-sensitive. Request a fresh quote if the interface marks the previous result as stale.

Understand the full cost

The receive estimate reflects the route response. Network gas and any route-specific costs should also be reviewed before confirmation.

  • Keep ETH for gas on Optimism.
  • Check price impact and slippage.
  • Confirm the destination network for cross-chain trades.

Common questions

Before you continue

Does Optimism use ETH for gas?

Yes. ETH is the network fee asset on Optimism.

Can I receive tokens on Base?

If an eligible cross-chain route exists for the selected assets, you can request an Optimism-to-Base quote.

Do quotes stay valid indefinitely?

No. Quotes are time-sensitive because market and network conditions change.
