That $4 worth of TRX for fee is high have you tried using Tronlink to see how much the fee will be their, and sometimes just have to fund your wallet with tron but you might not be charged up to that amount when the transaction will execute.
i have the private keys and full access just zero trx to pay the gas is there any way to swap this without having to buy trx first or is there a service that takes the fee out of the usdt directly cause looking at these fees makes me feel like this
You can’t do anything in any network without using its native token to settle gas, so you must get the TRX first before looking for any other option even in wallet swap options you will still need that TRX in other to approve the transaction.
