I made a swap on the site https://www.dextools.io/ and all attempts were unsuccessful, but for some reason, I was charged a fee. Solve this problem, please. I have lost more than $ 200-250.
Hello please note that the app does not charge a fee but there is a network fee that will be paid to the miners ( even if there is a failed transaction).
Once you try and send an amount, it automatically calculates the fees.
