How an Arbitrum swap works

After you choose the pair and amount, Betelgeuse requests a route and displays the expected amount out. Your wallet presents the approval and execution transactions associated with that route.

The amount shown is a quote, not a guaranteed market price. It can update as pool liquidity and network conditions change.

Prepare the wallet

Connect an EVM wallet on Arbitrum and keep enough ETH available for gas. If the input is an ERC-20 token, an approval may be required before execution.

  • Verify the network in both Betelgeuse and your wallet.
  • Review approvals before signing.
  • Wait for a confirmed status before treating the swap as complete.
