App Integration

If your application sends TRON transactions, you can add automatic energy with a single config change — replace the default node URL with your Energy-Free Node URL. No SDK changes, no new dependencies, no extra API calls.

Your existing code stays exactly the same. The node handles energy behind the scenes.

tronweb.js (JavaScript / Node.js)

One change: set fullHost to your Energy-Free Node URL.

const TronWeb = require('tronweb');

const tronWeb = new TronWeb({
  fullHost: process.env.TRON_NODE_URL, // https://node.tronagg.ai/YOUR_SECRET_KEY
});

tronWeb.setPrivateKey(process.env.TRON_PRIVATE_KEY);

// Send USDT — energy is purchased automatically before broadcast
const tx = await tronWeb.transactionBuilder.triggerSmartContract(
  'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t', // USDT contract
  'transfer(address,uint256)',
  {},
  [
    { type: 'address', value: 'RECIPIENT_ADDRESS' },
    { type: 'uint256', value: 1000000 }, // 1 USDT (6 decimals)
  ],
  tronWeb.defaultAddress.hex
);

const signedTx = await tronWeb.trx.sign(tx.transaction);
const result = await tronWeb.trx.sendRawTransaction(signedTx);
console.log('Transaction ID:', result.txid);

If you have an existing tronweb.js project, the migration is literally replacing the fullHost value. Every triggerSmartContract, sendRawTransaction, and contract call you already have will automatically get energy.

tronpy (Python)

One change: set the fullnode config to your Energy-Free Node URL.

from tronpy import Tron
from tronpy.keys import PrivateKey
import os

client = Tron(network='mainnet')
client.conf['fullnode'] = os.environ['TRON_NODE_URL']  # https://node.tronagg.ai/YOUR_SECRET_KEY

priv_key = PrivateKey(bytes.fromhex(os.environ['TRON_PRIVATE_KEY']))

# Send USDT — energy is purchased automatically before broadcast
contract = client.get_contract('TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t')  # USDT
txn = (
    contract.functions.transfer('RECIPIENT_ADDRESS', 1_000_000)
    .with_owner('YOUR_ADDRESS')
    .fee_limit(100_000_000)
    .build()
    .sign(priv_key)
)
result = txn.broadcast().wait()
print('Transaction ID:', result['id'])

Other languages / raw HTTP API

The Energy-Free Node is a standard TRON full node. Any HTTP client that speaks the TRON HTTP API can use it — just swap the base URL:

# Before (default node)
https://api.trongrid.io

# After (Energy-Free Node)
https://node.tronagg.ai/YOUR_SECRET_KEY

All standard TRON API endpoints work:

Endpoint	Description
POST /wallet/createtransaction	Create a TRX transfer
POST /wallet/triggersmartcontract	Call a smart contract (TRC20 transfers)
POST /wallet/broadcasttransaction	Broadcast a signed transaction
GET /wallet/getaccount	Get account info
GET /wallet/getnowblock	Get latest block

The energy purchase happens transparently when you call broadcasttransaction with a TRC20 transfer.

Best practices

Keep the URL out of source code

Your node URL is tied to your TRONAgg balance. Treat it like a database password.

// Good — from environment
const tronWeb = new TronWeb({
  fullHost: process.env.TRON_NODE_URL,
});

// Bad — hardcoded
const tronWeb = new TronWeb({
  fullHost: 'https://node.tronagg.ai/abc123secret',
});

• Store in environment variables or a secrets manager
• Never commit to version control
• Use separate URLs for development and production if needed

Use address whitelisting

If your app sends from a fixed set of addresses, enable address whitelisting in the dashboard. This ensures that only your known addresses can trigger energy purchases — even if someone obtains your node URL.

Monitor your balance

If your TRONAgg balance hits zero, the node still broadcasts your transactions — just without energy. TRX gets burned from your wallet at the full network rate. Keep an eye on the dashboard to avoid this.

Graceful degradation

The Energy-Free Node never blocks your transactions. Insufficient balance means your transaction goes through without energy — not that it fails. But you'll pay the higher burn rate (~6 TRX instead of ~2 TRX), so keep your balance funded.
