HATI ZA Msanidi Programu
TRONWEB INTEGRATION
Unganisha ugawaji wa TronEnergy Energy kwa kutumia TronWeb katika Node.js. Nakili na ubandike mifano ya msimbo ulio tayari.
ANUANI YA MALIPO YA API
TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx
Tuma TRX kwa anwani hii. Hashi yako ya tx inatumika kudai ugawaji wa nishati.
Kamilisha ujumuishaji wa Node.js kwa kutumia TronWeb . Kila hatua ni kizuizi cha msimbo kinachojitegemea ambacho unaweza kunakili katika mradi wako. Mfano kamili wa mwanzo hadi mwisho uko chini.
Masharti ya awali: Node.js 18+,
tronweb imewekwa (npm install tronweb), pochi ya Tron inayofadhiliwa.
Mtiririko
Hakuna ufunguo wa API . Hakuna usajili. Nambari yako hutuma TRX kwenye mnyororo kwenye anwani ya malipo TronEnergy , husaini ujumbe unaothibitisha umiliki, kisha hudai ugawaji. Energy hufika baada ya takriban sekunde 3. Kisha nambari yako hutuma USDT kwa kutumia nishati iliyokabidhiwa.
Bei ni ya mstari: Energy 16,250 kwa kila 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.
Hatua kwa Hatua
1. Usanidi
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. Tuma TRX
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. Dai Uwakilishi
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(`${API}/delegate`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
tx_hash: payment.txid,
delegate_to: tronWeb.defaultAddress.base58,
signature: sig,
}),
}).then(r => r.json());
if (delegation.error) {
throw new Error(delegation.message);
}
console.log('Energy delegated:', delegation.energy); // TRX_AMOUNT × 16,250
4. Tuma USDT
send usdt
const contract = await tronWeb.contract().at(USDT);
const tx = await contract.transfer(
recipientAddress, Math.round(usdtAmount * 1e6)
).send({ feeLimit: 50_000_000 });
console.log('USDT sent:', tx);
Kushughulikia Hitilafu
handling errors
const result = await fetch(`${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;
}
}
Mfano Kamili
Nakili hii kwenye faili, weka vigezo vyako vya mazingira, na uiendeshe. Hati hutuma TRX , husaini ujumbe, hudai uwasilishaji kwa kujaribu tena, kisha hutuma USDT .

Daima jumuisha sahihi. 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.
