What is USDT TRC-20
USDT TRC-20 is Tether issued on TRON under smart contract TR7NHqje... Transfers use energy and bandwidth rather than raw TRX fees. How it works and costs.
Published · Updated
USDT TRC-20 is Tether’s USD stablecoin issued on the TRON blockchain under the smart contract TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t[1].
Unlike native TRX transfers that consume only bandwidth, every USDT TRC-20 transfer executes smart contract code. This execution requires energy and bandwidth[2]. If your wallet holds no energy, the network burns ≈ 6.43 TRX[2] when transferring to an address holding USDT, and ≈ 13.03 TRX[2] when sending to an address with a zero USDT balance.

Each transfer is one 1-hour order at 25.34 SUN per energy; an order total rounds up to 1,000 SUN, as quotes do. Day average = the day's windows weighted by length. Burn: 100 SUN per energy (getEnergyFee). Schedule from the published grid.
Key technical parameters of USDT TRC-20
The following technical specifications define USDT on TRON:
| Parameter | Specification | Details |
|---|---|---|
| Contract address | TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t | Official Tether deployment on TRON mainnet[1] |
| Token standard | TRC-20 | TRON smart contract token interface |
| Decimals | 6 | 1 USDT = 1,000,000 base units |
| Energy (to USDT holder) | 64,285[3] | Recipient already holds USDT |
| Energy (to empty address) | 130,285[3] | Recipient’s USDT balance is zero |
| Bandwidth per transfer | ≈ 345[3] | Data payload size of the transaction |
| Burn price for energy | 100 SUN[2] | Network parameter getEnergyFee |
How fees work: Energy vs. Bandwidth
Every TRON transaction uses bandwidth; contract calls such as USDT transfers also use energy:
- Bandwidth: Measures the byte size of transaction data. Every active TRON address receives 600 a day[2] bandwidth free each day. Since a standard USDT transfer uses roughly ≈ 345[3] bandwidth, one transfer per day typically incurs zero bandwidth cost. If free bandwidth is exhausted, the network burns ≈ 0.35 TRX[2].
- Energy: Measures the computational effort required by the TRON Virtual Machine (TVM) to run contract functions[2]. A transfer to an existing USDT balance requires 64,285[3] energy. Sending to an empty account requires 130,285[3] energy (mainnet transfers, 2026-09-30).
If the sender account does not possess sufficient energy, the network burns TRX from the sender’s liquid balance. If the account has neither energy nor TRX, the transfer cannot proceed and can fail on chain with an OUT_OF_ENERGY error.
Difference between TRX and USDT TRC-20
Understanding the difference between native TRX and USDT TRC-20 is essential for avoiding failed transfers:
- TRX: The native cryptocurrency of the TRON network. It functions like ETH on Ethereum: it is used for staking, voting, and paying network fees.
- USDT TRC-20: A smart contract token hosted on TRON. You cannot pay network gas with USDT directly at the protocol level; the network strictly bills in energy, bandwidth, and TRX burn.
Some non-custodial wallets and protocols provide gasless options that deduct fees in USDT by relaying the transaction through an intermediary service. We detail these options in our guide on how to send USDT without TRX.
How to reduce USDT TRC-20 transfer costs
To avoid burning full TRX on every transaction:
- Verify the recipient’s balance: Use our address checker before sending to check whether the recipient already holds USDT (64,285 energy) or has a zero balance (130,285 energy).
- Rent energy beforehand: You can buy energy for your sender address. Once energy is delegated on chain, your USDT transfer consumes the delegated energy instead of burning TRX.
- Automate with API: If your platform processes high volumes of payouts or withdrawals, integrate our API to delegate energy programmatically before each transaction.

FAQ
What is USDT TRC-20?
USDT TRC-20 is the official Tether USD stablecoin issued as a smart contract token on the TRON blockchain. It follows TRON's TRC-20 token standard under contract address TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t.
How does a USDT TRC-20 transfer work on chain?
Unlike simple TRX coin transfers, moving USDT executes code inside the USDT smart contract. This execution consumes energy to run the contract logic and bandwidth to transmit the transaction data.
How much does it cost to send USDT TRC-20?
If the sender has no energy, the TRON network burns TRX from the sender's balance (roughly double if the recipient has no USDT balance). Renting energy beforehand significantly reduces this cost.
Why does USDT on TRON need TRX?
The TRON network burns TRX to pay for energy and bandwidth if an account does not have those resources delegated or staked. Without energy or sufficient TRX to burn, a USDT transfer cannot be completed.
