POST/v1/order

Create Energy order

Delegates the selected Energy package to a TRON wallet and charges your balance.

If the wallet is not activated, we activate it before delegating Energy. Activation costs an additional 1.2 TRX.

Energy is valid for 1 hour after delegation or until the first transfer, whichever comes first.

Before ordering, use the calculator to determine the required Energy package. Do not guess the amount.

Parameters

wallet requiredTRON address that will receive Energy.

energy requiredEnergy amount from the current tariffs. Use GET /v1/public/fee-estimate before each order to calculate the required package instead of choosing it manually.

trx_topupGuaranteed expense coverage. A 0.5 TRX fee is charged to your service balance. We automatically provide 400 Bandwidth for 1 hour or send 0.345 TRX to the sender wallet.

trx_topup_amountUse 0.345 when enabled and 0 when disabled. This is the service nominal, not the fee: do not pass 0.5 here.

Only these two combinations are accepted:

"trx_topup": false, "trx_topup_amount": 0 "trx_topup": true, "trx_topup_amount": 0.345

price_trxEnergy price only; the 0.5 TRX coverage fee is charged separately.

Response fields when coverage is enabled

trx_topup_sent=true: TRX was sent or the Bandwidth order was accepted. Delegation may still be in progress.
trx_topup_blockchain_tx_id: May be null until the transaction hash is available.

Example response

  "price_trx": 2.8,
  "balance_trx_after": 122.7

Quick instructions

⚡ Our service reduces the cost of USDT transfers on TRON — but works only with non-custodial wallets (TronLink, Trust Wallet, Bitget Wallet, etc.). It does not work with Binance, OKX, Bybit or other exchanges.

⚡ Energy required

If the receiver wallet has no USDT balance → you need 130,000 energy.
If the wallet already has USDT → you need 65,000 energy.
Energy is valid for 1 hour or until the first transfer (whichever comes first).

💳 Top up your balance

Use your Deposit address shown in the Balance block.
Send TRX only. Other assets are not accepted.
Minimum top-up is 10 TRX.

Top-ups are credited instantly, within 1 minute. If the top-up does not arrive, contact support.

🔒 Why do I need a password?

🔒

Password is used to encrypt the ZIP archive.

After download, unpack the archive and import the key into your wallet, or move it to a secure storage.
Then delete the archive from downloads / cloud backups.
We do not store your private key. Only you know the password.

📥 How to import? Security: don’t store keys in Downloads

Import steps (TronLink / Trust Wallet)

1) Download ZIP → unpack it using your password.

2) Copy private key and import:
• TronLink: Settings → Wallet Management → Import → Private Key
• Trust Wallet: Add Wallet → I already have a wallet → Tron → Private Key

3) Move the key to secure storage (or import and delete the file). Delete ZIP from Downloads / backups.

I understand: I am responsible for storing the private key and password. If I lose them, the address cannot be recovered.
