The Tron (TRX) blockchain is among the quickest and low-cost networks for sending USDT (TRC20). However, some users struggle—especially when they have USDT in their wallet but no TRX for gas fees. In this guide, we will explain TRX → USDT exchange process, sending USDT without TRX, how to reduce or avoid gas fees, and Tron energy options for cheaper transactions.
1. How to SWAP TRX to USDT Easily
Swapping TRX to USDT is straightforward and can be done on different centralized and decentralized platforms. Here are ways to do it:
A. Using Centralized Exchanges
You can swap TRX → USDT instantly on:
Binance
KuCoin
OKX
Bybit
Huobi
Steps:
Deposit TRX into your account.
Go to the “Trade” or “Convert” section.
Select TRX → USDT.
Approve the exchange.
B. Using Tron DEX Platforms
If you prefer a decentralized platform, use:
SunSwap (Tron’s official DEX)
JustSwap
Steps:
Connect your TronLink or Trust Wallet.
Select TRX in the “From” field and USDT in the “To” field.
Enter the amount.
Approve and swap.
2. Transfer USDT on Tron WITHOUT TRX – How It Works
Normally, you must have TRX in your wallet to pay transaction fees (called “energy” and “bandwidth”).
But there are a few ways to send SWAP TRX TO USDT without holding TRX:
A. Using “Fee Delegation” Wallets
Some wallets or services pay gas fees on your behalf:
OKX Web3 Wallet Gasless Transfer
TronLink’s “Energy Rental Service” (affordable and easy)
B. Using Exchange Withdrawals
If you withdraw USDT from Binance, OKX, KuCoin, etc., the exchange pays the gas fee, not you.
C. Rental Energy Services
Energy renting services execute your transaction using prepaid energy, meaning no TRX needed in your wallet.
3. How to Send USDT with Zero Gas Fee (No Gas Fee)
Here are ways to send USDT without paying gas:
1. Exchange Withdrawal – 100% Gas-Free
Most exchanges only charge a fixed withdrawal fee (e.g., 1 USDT).
No TRX needed in your wallet.
2. Tron Energy Rental – Almost Free
Platforms offering low-cost transactions:
TronSave
Sun.io Energy Pool
TronLink’s built-in “Rent Energy” feature
With rented energy, your transfer fee becomes 0.1–0.3 TRX, or zero, depending on the package.
3. Smart Contract Platforms with Fee Delegation
Some DeFi dApps allow gas-free transactions when using their platform.
4. Buy TRX Energy – Make Transactions Cheaper
If you do many transactions, buying energy helps save money.
Where to Buy Energy
You can buy TRX energy on:
Sun.io Energy Market
TronSave Energy Shop
TokenPocket / TronLink integrated energy services

Cost-effective for frequent users
