What TronWeb version is required?

TronWeb 6.x or later. Install via npm install tronweb. Note that the import is destructured: const { TronWeb } = require("tronweb").

Why does the signature have to come from the same wallet that sent TRX?

It is the API's only proof that you authorized the delegation. Without it, anyone watching the chain could claim energy for any payment.

TronWeb ውህደት | TronEnergy Docs

TronWeb በመጠቀም የNode.js ውህደትን ያጠናቅቁ። እያንዳንዱ እርምጃ ወደ ፕሮጀክትዎ መቅዳት የሚችሉት ራሱን የቻለ የኮድ ብሎክ ነው። ሙሉው ከጫፍ እስከ ጫፍ ያለው ምሳሌ ከታች ይገኛል።

ቅድመ ሁኔታዎች፡ ኖድ.ጄኤስ 18+፣ tronweb ተጭኗል (npm install tronweb) የገንዘብ ድጋፍ የሚደረግለት Tron ቦርሳ።

ፍሰቱ

API ቁልፍ የለም። ምዝገባ የለም። ኮድዎ TRX በሰንሰለት ወደ TronEnergy የክፍያ አድራሻ ይልካል፣ የባለቤትነት ማረጋገጫ መልእክት ይፈርማል፣ ከዚያም ውክልናውን ይጠይቃል። Energy በግምት በ3 ሰከንዶች ውስጥ ይደርሳል። ከዚያም ኮድዎ የተወከለውን ኃይል በመጠቀም USDT ይልካል።

ዋጋው መስመራዊ ነው፡ 16,250 በ TRX 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.

1. ማዋቀር

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 ላክ

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. ውክልናውን ይጠይቁ

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 ይላኩ

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);
  

የስህተት አያያዝ

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;
      }
    }
  

የተሟላ ምሳሌ

ይህንን ወደ ፋይል ይቅዱ፣ የአካባቢ ተለዋዋጮችዎን ያዘጋጁ እና ያሂዱት። ስክሪፕቱ TRX ይልካል፣ መልዕክቱን ይፈርማል፣ ውክልናውን እንደገና ይሞክሩ በማለት ይጠይቃል፣ ከዚያም USDT ይልካል።

ሁልጊዜ ፊርማውን ያካትቱ። 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.
