TronEnergy is a Tron Energy delegation service. It delegates computational resources to wallets on demand so USDT transfers go through at approximately 70% less cost than burning TRX.

How much does it cost?

Pricing is linear at 16,250 Energy per TRX. A standard USDT transfer needs 65,000 Energy, which costs 4 TRX via TronEnergy compared to approximately 13 TRX burning directly — roughly 70% savings. Minimum order is 4 TRX, maximum is 1,000 TRX (16.25 million Energy), and you can send any amount in between.

Do I need an API key?

No. TronEnergy uses signature-verified delegation. Your wallet signs a message proving you sent the payment, and that signature is the only credential the API needs.

Overview | TronEnergy Docs

TronEnergy delegates computational resources (Energy) to Tron wallets on demand, so USDT transfers go through at a fraction of their normal cost. No staking, no capital lockup, no wallet connection.

The Problem

Every USDT transfer on Tron requires a computational resource called Energy. Without it, the network burns your TRX or the transfer fails entirely.

65,000 Energy

Required for every standard USDT transfer. Double for first-time recipients.

~13 TRX Burned

What the network charges if you have no Energy. That is ~$3.50 per transfer.

8,851 Failures / Day

Our analysis of 834M transfers found 3.2 million failed due to insufficient Energy.

The Solution

Without TronEnergy

Burns ~13 TRX per transfer ($3.50)

Transfer fails if not enough TRX

User must buy TRX to cover the fee

With TronEnergy

From 4 TRX per transfer ($1.08) — linear at 16,250 Energy / TRX

Energy delegated in ~3 seconds

No wallet connection needed

Two Integration Paths

Simple (No Code)

Users send TRX to the TronEnergy wallet on tronnrg.com. Energy is delegated automatically. No API key, no wallet connection.

API (For Platforms)

Your platform calls our REST API to delegate Energy programmatically. Send TRX, sign a message to prove ownership, and claim via the API.

const API  = 'https://api.tronnrg.com';
const ADDR = 'TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx';

// Step 1: Send TRX to the payment address
// Linear pricing: 16,250 energy per TRX. Min 4 TRX (65k energy), max 1,000 TRX.
// 4 → 65k · 8 → 130k · 16 → 260k · 40 → 650k · 1000 → 16.25M
const delegateTo = 'TRecipientWallet';
const trxAmount  = 4; // change this for more energy
const payment = await tronWeb.trx.sendTransaction(ADDR, trxAmount * 1e6);

// Step 2: Sign — proves you are the sender
const message = `${payment.txid}:${delegateTo}`;
const signature = await tronWeb.trx.signMessageV2(message);

// Step 3: Claim the delegation
const result = await fetch(`${API}/delegate`, {
  method:  'POST',
  headers: { 'Content-Type': 'application/json' },
  body:    JSON.stringify({
    tx_hash:     payment.txid,
    delegate_to: delegateTo,
    signature,
  }),
}).then(res => res.json());

console.log(result.energy);              // trxAmount × 16,250 (e.g. 4 → 65000)
console.log(result.delegations[0].tx);  // on-chain tx hash
console.log(result.ref);                 // "nrg_d_42"

COUNTRIES

Non-Custodial

We never hold user USDT or tokens. Energy is delegated via the Tron protocol. No wallet connection required.

Automatic Refunds

If delegation fails after payment, TRX is automatically refunded to the sender address on-chain.

15-Minute Lock

Energy is delegated for 15 minutes. More than enough time to complete your USDT transfer.
