# Swap configuration

Here, we will guide you through the step-by-step process of configuring additional settings using the fly.trade app.

**Gasless feature** : 

fly.trade executes the transaction on behalf of the user, covering the gas fees, so the user doesn’t need to hold or pay gas in the native currency.
