Your USDT is there, but the transfer will not start
A wallet asking for TRX does not necessarily mean your USDT is lost or locked. Holding tokens and having the resources to send them are separate things.
This guide covers USDT on TRON (TRC-20) in a wallet you control. Exchange withdrawals follow the exchange’s own rules and fees.
What the transfer needs
Energy pays for executing the USDT contract; Bandwidth covers transaction data. A resource shortfall can require TRX.
Renting Energy addresses only one part of the cost. Check available Bandwidth separately before trying to send with zero TRX.

Choose a route that fits your situation
Have TRX in another wallet? Send a small reserve to the USDT wallet, or fund your service account and order Energy for the intended address. Compare the total costs.
Already have a funded GasFree4you account? Place an Energy order for your USDT wallet. An account balance does not automatically become resources on that address.
Have neither TRX nor a funded account? You need an external source of resources, such as delegation from someone you trust or a service explicitly offering payment in USDT. A normal swap from USDT to TRX also needs network resources.
Prepare the transfer with GasFree4you
- Select USDT on TRON (TRC-20) in your wallet and copy the public sending address.
- Check your GasFree4you account balance. If needed, fund it using the current deposit instructions.
- Estimate Energy for the planned transfer. Enter the USDT sending address in the order and choose the amount and rental duration.
- Wait for fulfillment. Check Energy on the sending address in your wallet or Tronscan, and check Bandwidth separately.
- Return to your wallet, enter the recipient and USDT amount, then review the network, address and estimated costs before confirming.
- Check the transaction result in Tronscan and save its hash.
Keep the addresses separate
If wallet A sends USDT to wallet B, order Energy for A. Renting it for B does not supply the sender.
The account deposit address has a different purpose: funding services. Do not send your USDT there instead of placing an Energy order.
How much Energy should you order?
Estimate the actual transfer just before ordering. Contract execution, current parameters and address state affect consumption; an old screenshot is not a guarantee.
Do not calculate Energy as a percentage of the USDT amount. Check the rental duration and allow for other operations that may use the resource first.

If the wallet still asks for TRX
- Compare the order address with the USDT sending address, refresh the wallet and check resources in Tronscan.
- Check fulfillment, rental expiry and remaining Energy and Bandwidth.
- Estimate costs again. If the app still blocks sending, ask its support to explain the restriction before confirming.
- If a transaction was broadcast, check its status first. Investigate OUT_OF_ENERGY before retrying: a failed transaction may also consume resources.

Before you confirm
Delegation needs your public address, not your recovery phrase, private key or permission to spend your USDT. Sign the transfer in your own wallet.
Check the full recipient address and confirm support for USDT TRC-20. A test transfer needs its own resources, separate from the main transfer.
Can the fee simply be deducted from my USDT?
A regular USDT TRC-20 transfer does not automatically convert some of your USDT into network resources. Paying in USDT requires a service that explicitly supports it, under its own terms. A USDT balance alone does not guarantee that a regular transfer can proceed.
