Check what the wallet says is missing
Make sure you selected USDT on TRON, not another network. Check available resources and the transfer estimate. “Not enough TRX” may be a fee warning rather than a shortage of the USDT you intend to send; account activation and wallet-specific checks can also matter.
Resolve the first-transfer problem
You can fund the sending address with TRX from another account you control. Some wallets offer a way to pay network fees in USDT, but availability and conditions differ. Follow that wallet’s official instructions rather than assuming that a gas-free feature exists in every wallet.
Why swapping USDT for TRX is not always the first step
Sending USDT to an exchange address is itself an on-chain transaction. If your account cannot make that first transfer, trxPay.io’s exchange cannot bypass the resource shortage. Solve the initial fee requirement before following an exchange tutorial.
When the trxPay.io exchange can help
If you can already send USDT TRC20, the auxiliary exchange accepts 10–100 USDT per transaction, charges 0.5%, and usually returns TRX to the actual paying address within 3–60 seconds after receipt. Use the current exchange address on the homepage, not the Energy rental address.
Frequently asked questions
Can I pay for a trxPay.io Energy rental with USDT?
The current rental flow takes the displayed TRX payment. A wallet provider’s USDT fee-payment feature is a different service.
Does gas-free mean every transfer costs nothing?
Not necessarily. A wallet may charge in another token or apply eligibility rules. Read its terms; do not confuse that feature with a prepaid Energy rental.
