Rent Tron Energy to cut USDT TRC20 fees
Tron Energy is the network resource that pays for each USDT TRC-20 transfer. If your address has none, Tron burns TRX from it to cover the fee. Soon you can rent energy from Crypto APIs before you send and pay less per transfer, with no TRX to lock, paid from your prepaid Crypto Balance, by API or in the dashboard.
How much can you save on USDT TRC-20 fees?
Enter your daily transfers. The calculator will compare burning TRX with renting energy at the market price of the day.
How do Tron energy and bandwidth work?
Tron has two resources. Bandwidth pays for the bytes of a transaction. Energy pays for running a smart contract, and a USDT transfer is a smart contract call.
You get energy by staking TRX, by renting it, or the network burns TRX for you at the moment of sending. Renting is the way to get energy without locking TRX.
How will I rent Tron energy?
Four steps. Tron Energy will be paid from your prepaid Crypto Balance, not from a monthly subscription.
Fill your Crypto Balance
Fill it with USDT on Tron. The Balance is prepaid, in USD.
Rent energy for an address
Call the API or click Rent in the dashboard. Energy is delegated to the address you give us.
Send your USDT transfer
Sign and send as usual. The transfer uses the rented energy instead of burning TRX.

Tron Energy questions
What is Tron energy?
Energy is the Tron resource that pays for smart contract calls, such as a USDT TRC-20 transfer. If the sending address has no energy, the network burns TRX from it to cover the cost.
Why does my USDT TRC-20 transfer cost TRX?
Because the sending address had too little energy, so the network burned TRX to pay for it. Renting energy for that address before you send replaces most of that burn with a smaller rental fee.
What does "out of energy" or "energy is lower than necessary" mean?
The address did not have enough energy or TRX to pay for the contract call, so the transfer failed. Get enough energy for the address, or top up its TRX, and send again.
How will I pay for Tron Energy?
From your prepaid Crypto Balance in the Crypto APIs dashboard, which you fill with USDT on Tron. Each rental is taken from the Balance. Tron Energy and the Crypto Balance are coming soon.
Is renting energy cheaper than staking TRX?
Staking TRX gives you energy without a fee, but you lock the TRX. Renting costs a fee per rental and locks nothing. The calculator above will compare it with burning TRX for your own volume.
Do you need my private key?
No. Energy is delegated to your address by its public address alone. You keep your keys and sign your own transfers.
