Buy energy
Buy TRON energy for a USDT transfer
A USDT TRC-20 transfer needs about 65,000 Energy if the receiving address already holds USDT, and about 131,000 Energy if its USDT balance is zero. Renting that energy costs from 1.89 TRX, against roughly 6.85 TRX burned when you send without it. All we need is the public address you send from — never a seed phrase or a private key.
Prices follow the energy market and were last updated November 5 at 12:57 PM UTC; the full table and its history are on the energy price page. Network parameters such as the burn rate per unit of energy are set by governance vote and change over time — the figures below describe how things stood on that date.
Amount
How much energy to take for your transfer
The recipient decides the cost, not the amount you send. Sending 10 USDT and 10,000 USDT costs exactly the same.
| Your case | Energy needed | If you take less |
|---|---|---|
| Receiving address holds USDT already | ~65,000 | The transfer fails or the missing part is burned from your TRX — you pay more than renting would cost. |
| Receiving address holds no USDT | ~131,000 | The contract has to create a balance record for the recipient, which roughly doubles the energy. Ordering the smaller amount is the most common reason a transfer still fails after renting. |
| Transfer to an exchange deposit address | ~65,000 / ~131,000 | Whichever of the two cases above is true of that address. Deposit addresses are usually swept to a zero USDT balance, so the larger amount is the safer assumption — check it rather than assume it. Separately: rented energy cannot be delegated to an exchange address, so you rent it for the wallet you send from. |
These are the usual figures for the USDT contract. The exact cost of a particular transfer depends on the contract state and on current network parameters — you can always read the real number from a recent USDT transfer on TronScan.
Shortfall
What happens when there is not enough energy
One of two things, and both cost you more than renting would have.
A transfer also consumes about 350 bandwidth. Every account gets a small free bandwidth allowance each day; once it is used, bandwidth is also paid in TRX. That is why a wallet with zero TRX can be stuck even when its energy is covered.
Choice
Rent per transfer, rent for a run of them, or stake TRX
Three ways to get energy. The right one depends on how often you send, not on how much you send.
The practical rule: at a few transfers a month, buying TRX to stake does not pay off — the locked capital costs more than the rentals. Staking starts to make sense when you send every day and the amount to freeze pays for itself in weeks rather than years.
Step by step
How to buy energy before a transfer
- 1
Paste the address you send USDT from
Not the recipient's address. Energy is spent by the sender, so it must be delegated to your own wallet. Sending it to the recipient is the most common mistake.
- 2
Choose the amount of energy
Take 65,000 for an address that already holds USDT and 131,000 if its USDT balance is zero. If you are unsure, take the larger amount — the difference in price is smaller than a failed transfer.
- 3
Pay from your TRX balance
The price is shown before you confirm and is charged from the balance you topped up with USDT or TRX. No card, no invoice, no waiting for an operator.
- 4
Wait for the delegation
Energy is delegated on-chain with the standard DelegateResource function. The order shows the transaction id, so you can see the exact moment it landed.
- 5
Send the USDT transfer within 15 minutes
That is how long the rental lasts, and it is the only period we sell — enough for a transfer you are about to make, and short enough that it is worth ordering right before you send rather than in advance. Your wallet uses the delegated energy instead of burning TRX.
Verification
How to check that the energy arrived
Two ways, both take a few seconds and neither requires trusting us.
Safety
Is renting energy safe
Delegation hands over a resource, not access. It is worth knowing exactly where the line is.
What we need
Your public address — the one starting with T that you already share to receive money — and an email for the account. Nothing else is technically required to delegate energy.
What we cannot do
Move your USDT or TRX, sign anything on your behalf, or take the energy back before the rental ends. Delegation is a protocol function that grants resources and nothing more.
How to spot a scam
It asks for your seed phrase or private key. It asks you to connect a wallet and sign a transaction that moves funds. It operates only through private messages, with no public address, no price page and no TronScan trail. A real energy service never needs any of that.
Cost
Renting against burning TRX, on one transfer
One USDT transfer to an address that already holds USDT, priced as of November 5 at 12:57 PM UTC.
| Way to pay for it | What happens | Cost |
|---|---|---|
| Send without energy | The network burns your TRX at 100 sun per unit of energy, plus bandwidth | ~6.85 TRX |
| Rent 65,000 Energy for 15 minutes | Energy is delegated to your wallet and used by the transfer | 1.89 TRX |
| Rent 131,000 Energy for 15 minutes | Same, for a recipient whose USDT balance is zero | 3.61 TRX |
That is about 72% off a single ordinary transfer. We deliberately quote this in TRX and energy rather than in dollars: the TRX rate moves daily, the ratio between renting and burning does not.
Habits
How to stop overpaying
- Check the recipient before you send, not after. If their USDT balance is zero, the transfer needs roughly twice the energy — decide that before the wallet decides for you.
- Rent before the transfer, never after a failure. A failed attempt already costs a fee, and the second attempt costs the same as the first would have.
- Take the larger amount when you are unsure. The gap between the two amounts is small; the gap between a successful and a failed transfer is not.
- Keep only a little TRX in the wallet, but not zero. Bandwidth is paid in TRX once the free daily allowance runs out, and without it the transaction cannot be broadcast.
- Go by the balance, not by the history. An address is expensive whenever its USDT balance is zero — the first payment to a new wallet, and equally the next payment to one that has since been emptied.
Paste your address and the energy is delegated before you send
No private key and no seed phrase — a public address is all it takes.
