In this guide, we will explain TRX → USDT exchange process, sending USDT without TRX, gasless USDT transfer tips, and Tron energy options for cheaper transactions.

2. Transfer USDT on Tron WITHOUT TRX – Can You Do It?
Normally, you must have TRX in your wallet to pay transaction fees (called “energy” and “bandwidth”).
