Base

Swap tokens on Base

Use ETH for network fees while swapping supported assets on Base. Betelgeuse keeps the quote, route and transaction approval in one interface.

Open Base swapHow routing works

A direct route into Base liquidity

Select Base in the network control, choose the tokens and enter an amount. Betelgeuse returns the available quote and prepares the transaction only after a wallet is connected.

Base uses ETH as its gas asset. A small ETH balance is still required when paying with a stablecoin or another ERC-20 token.

Same-chain and cross-chain choices

A same-chain swap stays on Base. A cross-chain route can include bridging and a destination-chain swap, which means more steps and a longer completion time than a same-chain trade.

  • Confirm the source and destination networks.
  • Check the destination wallet address.
  • Compare the quoted output rather than the displayed spot price alone.
