Hi, I wanted to exchange the RFX / ETH pair through uniswap, but no transaction was made and the cost was deducted. Please help me how to get the fee.
If your RFX was not exchanged, then you simply approved it. When swapping tokens for the first time, you have to approve it first to be spendable. And, that is what you did just now.
Since you are done approving the token, you need to enter the amount that you want to exchange then press the swap button.
All in all, you will confirm two transactions: approve and swap
Now what should I do? How can I get the deducted fee or make a new transaction to pay the fee? The fee is paid to the RFX contract. Hash transaction
Proceed with the swap now by entering the amount of RFX then confirm the transaction.
