HATI ZA WASANIDI
Kukodisha Nishati ya Tron na TronWeb (Node.js): Mifano ya Msimbo
Kukodisha Nishati ya Tron kwa kutumia TronWeb katika Node.js. Tuma 4 TRX, dai nishati 65,000 kupitia API, na kutuma USDT kwa asilimia 70 chini. Msimbo wa kunakili-kupasta na kushughulikia kosa.
ANWANI YA MALIPO YA API
TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx
Tuma TRX kwa anwani hii. Hash yako ya tx inatumika kudai kubadilisha nishati.
Ujumuishaji kamili wa Node.js kwa kutumia TronWeb. Kila hatua ni kizuizi cha msimbo kaeni unaweza kunakili katika mradi wako. Mfano kamili wa mwisho hadi mwisho uko chini.
Mahitaji: Node.js 18+,
tronweb iliyosanidi (npm install tronweb), pochi ya Tron iliyokamatia fedha.
Mtiririko
Hakuna ufunguo wa API. Hakuna ujasiriamali. Msimbo wako unatuma TRX kwenye mlolongo kwa anwani ya malipo ya TronEnergy, unasaini ujumbe uthibitishacho kuwa mamiliki, kisha unaidai kubadilisha nishati. Nishati inakamatia katika takriban 3 sekunde. Kisha msimbo wako unatuma USDT kwa kutumia nishati iliyobadilishwa.
Bei ni mstari: Nishati 16,250 kwa TRX. Agizo la chini 4 TRX (Nishati 65,000 — kubadilisha USDT moja kwa kawaida), kiwango cha juu 1,000 TRX (Nishati 16.25M). Kiasi unachotuma kinaamua kwa usahihi ni kiasi gani cha Nishati kinachofika — hakuna ngazi au paketi. Kwa kubadilisha moja kwa kawaida, tuma 4. Kwa kubadilisha kwa pochi mpya, tuma 8. Kwa kazi ya kundi, tuma zaidi. Msimbo chini unatumia
trxAmount kigezo kwa hivyo unaweza kubadilisha katika mahali pamoja.
Hatua kwa Hatua
1. Kuandaa
kuandaa
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
kutuma malipo
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 Haki ya Kukodisha Nishati
kukuza ridhaa
// Sign: proves you are the sender
const msg = `${payment.txid}:${tronWeb.defaultAddress.base58}`;
const sig = await tronWeb.trx.signMessageV2(msg);
const delegation = await fetch(`${API}/delegate`, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
tx_hash: payment.txid,
delegate_to: tronWeb.defaultAddress.base58,
signature: sig,
}),
}).then(r => r.json());
if (delegation.error) {
throw new Error(delegation.message);
}
console.log('Energy delegated:', delegation.energy); // TRX_AMOUNT × 16,250
4. Tuma USDT
kutuma USDT
const contract = await tronWeb.contract().at(USDT);
const tx = await contract.transfer(
recipientAddress, Math.round(usdtAmount * 1e6)
).send({ feeLimit: 50_000_000 });
console.log('USDT sent:', tx);
Kushughulikia Hitilafu
kushughulikia makosa
const result = await fetch(`${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 vigeu vya mazingira yako, na endesha. Hati hiyo inatuma TRX, inasaini ujumbe, inaida kukodisha nishati kwa kurudia, kisha inatuma USDT.

console.log('Payment:', payment.txid);
// 2. Claim delegation
// Sign: proves you are the sender
const message = `${payment.txid}:${recipient}`;
const signature = await tronWeb.trx.signMessageV2(message);
const result = await claimWithRetry(payment.txid, recipient, signature);
console.log('Delegated:', result.energy, 'energy');
console.log('Delegation tx:', result.delegations[0].tx); // verify on TronScan
console.log('Ref:', result.ref);
// 3. Send USDT
const contract = await tronWeb.contract().at(USDT);
const tx = await contract.transfer(recipient, 10 * 1e6).send();
console.log('USDT sent:', tx);
}
main().catch(console.error);
Daima jumuisha saini. Inathibitisha wewe ni pochi iliyotuma TRX. Bila hiyo, API inakataa ombi na
missing_signature.
