API 付款地址
TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx
向该地址发送 TRX。交易哈希用于领取能量委托。

使用 TronWeb 的完整 Node.js 集成。每一步都是可以直接复制进项目的独立代码块,完整的端到端示例在页面底部。

前置条件: Node.js 18+,已安装 tronwebnpm install tronweb),以及一个有余额的波场钱包。

流程

无需 API 密钥,无需注册。您的代码向 TronEnergy 付款地址在链上发送 TRX,对一条消息签名以证明所有权,然后领取委托。能量约 3 秒到账。随后代码使用委托的能量发送 USDT。

线性定价:每 TRX 兑换 16,250 能量。 最低订单 4 TRX(65,000 能量 — 一笔标准 USDT 转账),最高 1,000 TRX(1,625 万能量)。发送数量精确决定返还的能量,没有梯度或套餐。单笔标准转账发 4,新钱包转账发 8,批量任务发更多。下面的代码使用 trxAmount 变量,改一处即可全局生效。

分步说明

1. 初始化

初始化
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. 发送 TRX

发送付款
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. 领取委托

领取委托
// 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. 发送 USDT

发送 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);

错误处理

处理错误
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; } }

完整示例

把这段代码复制到文件里,配置好环境变量,直接运行。脚本会发送 TRX、对消息签名、带重试地领取委托,然后发送 USDT。

delegate-energy.js
const { TronWeb } = require('tronweb'); // destructured: 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'; const USDT = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t'; async function claimWithRetry(txHash, delegateTo, signature, retries = 3) { for (let i = 0; i < retries; i++) { const res = await fetch(`${API}/delegate`, { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ tx_hash: txHash, delegate_to: delegateTo, signature }), }).then(r => r.json()); if (!res.error) return res; if (res.error !== 'payment_verification_failed') throw new Error(res.message); await new Promise(r => setTimeout(r, 3000)); } throw new Error('Transaction not found after retries'); } async function main() { const recipient = 'TRecipientWallet'; const trxAmount = 4; // min 4, max 1000 — you get trxAmount × 16,250 energy // 1. Send TRX (linear pricing: 16,250 energy per TRX) const payment = await tronWeb.trx.sendTransaction(ADDR, trxAmount * 1e6); console.log('Payment:', payment.txid); // 2. Claim delegation // Sign: proves you are the sender const message = `${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);
签名务必带上。 它证明您就是发送 TRX 的那个钱包。缺少签名时,API 会以 missing_signature 拒绝请求。
