TRONWEB INTEGRATION
Node.js da TronWeb yordamida TronEnergy Energy delegatsiyasini integratsiya qiling. Tayyor kod misollarini nusxalash va joylashtirish.
API TO'LOV MANZILI
TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx
TRX ushbu manzilga yuboring. Sizning tx xeshingiz energiya delegatsiyasini talab qilish uchun ishlatiladi.
TronWeb yordamida Node.js integratsiyasini yakunlang. Har bir qadam mustaqil kod bloki bo'lib, uni loyihangizga nusxalashingiz mumkin. To'liq boshdan oxirigacha misol quyida keltirilgan.
Talablar: Node.js 18+,
tronweb o'rnatilgan (npm install tronweb), moliyalashtirilgan Tron hamyoni.
Oqim
API kaliti yo'q. Ro'yxatdan o'tish yo'q. Kodingiz TRX TronEnergy to'lov manziliga zanjir orqali yuboradi, egalikni tasdiqlovchi xabarni imzolaydi va keyin delegatsiyani talab qiladi. Energy taxminan 3 soniyada yetib keladi. Keyin kodingiz delegatsiya qilingan energiya yordamida USDT yuboradi.
Narxlar chiziqli: har bir TRX uchun 16 250 Energy . 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.
Bosqichma-bosqich
1. Sozlash
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 yuboring
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. Delegatsiyani talab qiling
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(`${API}/delegate`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
tx_hash: payment.txid,
delegate_to: tronWeb.defaultAddress.base58,
signature: sig,
}),
}).then(r => r.json());
if (delegation.error) {
throw new Error(delegation.message);
}
console.log('Energy delegated:', delegation.energy); // TRX_AMOUNT × 16,250
4. USDT ni yuboring
send usdt
const contract = await tronWeb.contract().at(USDT);
const tx = await contract.transfer(
recipientAddress, Math.round(usdtAmount * 1e6)
).send({ feeLimit: 50_000_000 });
console.log('USDT sent:', tx);
Xatolarni boshqarish
handling errors
const result = await fetch(`${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;
}
}
To'liq misol
Buni faylga nusxalang, muhit o'zgaruvchilarini o'rnating va ishga tushiring. Skript TRX yuboradi, xabarni imzolaydi, delegatsiyani qayta urinish bilan tasdiqlaydi va keyin USDT yuboradi.

Har doim imzo qo'ying. 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.
