# Swap XLM ↔ USDC

Agents can swap between XLM and USDC on the Stellar DEX.

<Steps>
  <Step title="Fund and trustline">
    Fund XLM. If swapping into USDC, open a Circle USDC trustline from Connect if needed.
  </Step>

  <Step title="Quote">
    Call `get_swap_quote` with `from_asset`, `to_asset`, and `amount`.
  </Step>

  <Step title="Swap">
    Call `swap` with the same fields. Optional `max_slippage_bps` (default `100` = 1%). Large notional may require confirmation.
  </Step>
</Steps>

Swaps use path payment strict-send. They do **not** count toward daily outbound spend caps the same way transfers do.
