Open the transaction in your own wallet
Enter the recipient and amount without signing. Many wallets show a resource or fee estimate at this stage. This is more useful than relying on a fixed fee shown on another website.
Review Energy, Bandwidth, and TRX
Energy is associated with smart-contract execution; Bandwidth is a separate resource for transaction data. Keep a small TRX balance for possible resource shortfalls. A package does not promise a fixed number of successful transfers.
Check just before payment and sending
Estimates are time-sensitive. Recheck the address, selected package duration, and wallet estimate shortly before paying or signing. Only pay from the wallet that is intended to receive delegated resources and later send the transaction.
Open the package estimator →Read the estimate in the same wallet that will send
The useful Energy figure is the value shown by the wallet that will sign the smart-contract transaction. A second wallet, an exchange withdrawal screen, or a screenshot from an earlier attempt may not describe the transaction you are about to send. Start the transfer flow, review the estimate, and compare it with the wallet’s currently available resources.
Four values worth checking
- Energy: the resource expected for smart-contract execution.
- Bandwidth: a separate network resource that can still matter.
- TRX balance: a buffer for any resource shortfall or wallet-required cost.
- Recipient and token: the destination and asset shown in the final confirmation screen.
Use the live estimate as a planning tool, not a guarantee. The wallet can refresh the calculation when transaction conditions change, so make the final check immediately before signing.
How to verify rental delivery
- Check the Energy estimate in the wallet that will send USDT. Choose a package that covers the shortfall.
- Transfer the exact listed TRX price from that same wallet to the official payment address. Do not use an exchange withdrawal address.
- Look up your sending address on TRONSCAN or in your wallet. Check available Energy (Energy limit minus Energy used); a confirmed TRX payment alone does not prove delegation has arrived.
- After Energy arrives, review the USDT estimate again and send within the one-hour rental window. Keep TRX available for possible additional costs.
- If resources do not arrive, send support the public payment transaction ID, sender address and payment time. Do not repeatedly pay to resolve the same issue.
