TRONWEB INTEGRATION
Интегратсияи ҳайати TronEnergy Energy бо истифода аз TronWeb дар Node.js. Мисолҳои рамзи омодаро нусхабардорӣ ва часбонед.
СУРОҒАИ ПАРДОХТИ API
TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx
TRX ба ин суроға фиристед. Хэши tx-и шумо барои гирифтани тақсимоти энергия истифода мешавад.
Ҳамгироии пурраи Node.js-ро бо истифода аз TronWeb анҷом диҳед. Ҳар як қадам як блоки рамзи мустақил аст, ки шумо метавонед онро ба лоиҳаи худ нусхабардорӣ кунед. Мисоли пурраи аз аввал то охир дар поён оварда шудааст.
Пешшартҳо: Node.js 18+,
tronweb насбшуда (npm install tronweb), ҳамёни Tron , ки маблағгузорӣ мешавад.
Ҷараён
Калиди API нест. Бақайдгирӣ нест. Рамзи шумо TRX ба суроғаи пардохтии TronEnergy дар шабака мефиристад, паёмеро имзо мекунад, ки моликиятро тасдиқ мекунад ва сипас ваколатро талаб мекунад. Energy тақрибан дар 3 сония мерасад. Сипас, рамзи шумо бо истифода аз энергияи ваколатдор USDT мефиристад.
Нархгузорӣ хаттӣ аст: 16,250 Energy барои TRX . Minimum order 4 TRX (65,000 Energy — one standard USDT transfer), maximum 1,000 TRX (16.25M Energy). The amount you send determines exactly how much Energy comes back — there are no tiers or packages. For a single standard transfer, send 4. For a new-wallet transfer, send 8. For batch work, send more. The code below uses a
trxAmount variable so you can change it in one place.
Қадам ба қадам
1. Танзимот
setup
const { TronWeb } = require('tronweb'); // destructured: the default import is broken in v6
const tronWeb = new TronWeb({
fullHost: 'https://api.trongrid.io',
privateKey: process.env.TRON_PRIVATE_KEY,
});
const API = 'https://api.tronnrg.com';
const ADDR = 'TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx'; // API payment address
const USDT = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t';
2. TRX фиристед
send payment
const TRX_AMOUNT = 4; // Linear: 16,250 energy per TRX. Min 4, max 1000.
// 4 → 65k (standard) · 8 → 130k (new wallet) · 40 → 650k (10 transfers)
const payment = await tronWeb.trx.sendTransaction(ADDR, TRX_AMOUNT * 1e6);
console.log('Payment tx:', payment.txid);
3. Даъвои намояндагӣ
claim delegation
// Sign: proves you are the sender
const msg = `${payment.txid}:${tronWeb.defaultAddress.base58}`;
const sig = await tronWeb.trx.signMessageV2(msg);
const delegation = await fetch(`${API}/delegate`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
tx_hash: payment.txid,
delegate_to: tronWeb.defaultAddress.base58,
signature: sig,
}),
}).then(r => r.json());
if (delegation.error) {
throw new Error(delegation.message);
}
console.log('Energy delegated:', delegation.energy); // TRX_AMOUNT × 16,250
4. USDT фиристед
send usdt
const contract = await tronWeb.contract().at(USDT);
const tx = await contract.transfer(
recipientAddress, Math.round(usdtAmount * 1e6)
).send({ feeLimit: 50_000_000 });
console.log('USDT sent:', tx);
Коркарди хатогиҳо
handling errors
const result = await fetch(`${API}/delegate`, { ... })
.then(r => r.json());
if (result.error) {
switch (result.error) {
case 'payment_verification_failed':
// Payment not yet indexed on-chain. Wait 3s and retry.
break;
case 'hash_already_used':
// Already claimed. Don't retry.
break;
case 'signature_mismatch':
// Sender of TRX != signer of the message. Sign with the same key.
break;
case 'delegation_failed':
// Provider could not deliver. Retry or contact support with result.ref.
break;
}
}
Намунаи пурра
Инро ба файл нусхабардорӣ кунед, тағирёбандаҳои муҳити худро муқаррар кунед ва онро иҷро кунед. Скрипт TRX мефиристад, паёмро имзо мекунад, ваколатро бо такрори такрорӣ талаб мекунад ва сипас USDT мефиристад.

Ҳамеша имзоро дохил кунед. It proves you are the wallet that sent the TRX. Without it, the API rejects the request with
missing_signature. The signature is what makes the API safe to use without an API key: it cryptographically proves you authorised the delegation.
