Geekstaiton 1 day agoThe Tron (TRX) blockchain is among the quickest and low-cost networks for sending USDT (TRC20). However, many users face common issues—especially when they have USDT in their wallet but no TRX for gas fees. In this guide, we will explain how to swap TRX to USDT, sending USDT without TRX, how to reduce or avoid gas fees, and where to buy or rent Tron energy.
1. How to Exchange TRX for USDT
Swapping TRX to USDT is straightforward and can be done on various exchanges or DEX 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.
Click swap to complete.
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 – Is It Possible?
Normally, you must have TRX in your wallet to pay transaction fees (called “energy” and “bandwidth”).
But there are three ways to send 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” (low-cost 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 allow gas-free transactions, meaning no TRX needed in your wallet.
3. How to Send USDT with Zero Gas Fee (USDT Gas Fee Free)
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 cheap 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 free transactions when using their platform.
4. buy trx energy – Make Transactions Cheaper
If you do many transactions, buying energy helps save money.

Sun.io Energy Market
TronSave Energy Shop
