The FOMOEgg egg in the studio, illustrating: What are gas fees?
Short answer

A fee paid to the network to process your transaction. A failed swap can still cost gas.

How to check it yourself

  1. Read the network fee line on the confirm screen before you sign.
  2. Look up a past transaction on the explorer and find the fee paid.
  3. Keep a small balance of the gas token, since even a failed transaction uses gas.
