The USDT TRC-20 transfer fee, explained
A clear look at what you pay for when sending USDT on TRON and how to keep that cost low.
Energy and bandwidth in one minute
The TRON network charges for work in two resources. Bandwidth pays for the size of a transaction, and energy pays for running smart contracts. A plain TRX transfer needs only bandwidth. A USDT transfer runs a smart contract, so it needs energy too.
Every address gets 600 bandwidth free each day, enough for a couple of transfers. Energy is not free, and that is where the real cost comes from.
What one transfer needs
- About 65,000 energy when the recipient already holds USDT.
- About 130,000 energy when the recipient's address has never held USDT.
- About 345 bandwidth for the transaction itself.
Where the TRX goes
If the energy isn't on your address, the network burns TRX to cover it at the current rate of 100 SUN per unit, about 6.5 TRX for a standard USDT transfer. Missing bandwidth burns roughly another 0.35 TRX.
Three ways to pay for energy
- Burn TRX on every transfer: no preparation, but the most expensive option.
- Stake your own TRX: energy refills every 24 hours, but covering even one transfer a day locks thousands of TRX.
- Rent energy: you pay only for the time you need, and the cost is a fraction of burning.
Renting on tron.rent
Connect TronLink or Trust Wallet, choose how many transfers you need and for how long, and approve one TRX payment. Energy arrives on your address, usually within a minute, and stays there for the time you picked.
Mistakes that cost extra
- Renting energy for 65,000 when the recipient has never held USDT. The transfer needs twice as much.
- Keeping zero TRX on the address. Without bandwidth a transfer burns extra TRX even with energy.
- Paying for a long period when you only need a single transfer. Five minutes is often enough.
