使用 Python (tronpy) 租用 TRON 能量：代码示例
使用 Python 中的 tronpy 租用 TRON 能量。完整集成示例：支付 4 TRX、领取能量委托，并在 TRON 网络上发送 USDT 转账。
API 支付地址
TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx
向此地址发送 TRX。您的交易哈希用于领取能量委托。
使用 tronpy 的完整 Python 集成。每个步骤都是独立的代码块，您可以复制到项目中。完整的端到端示例在底部。
前置要求： Python 3.8+、
tronpy 已安装（pip install tronpy），以及一个有资金的 TRON 钱包。
工作流程
无需 API 密钥。无需注册。您的代码在链上向 TronEnergy 支付地址发送 TRX，签名证明所有权，然后领取委托能量。能量将在约 3 秒内到达。然后您的代码使用委托能量发送 USDT。
定价是线性的：每 TRX 对应 16,250 能量。 最小订单 4 TRX（65,000 能量 — 一次标准 USDT 转账），最大 1,000 TRX（1,625 万能量）。您发送的金额决定了返回的能量数量 — 没有分级或套餐。单次标准转账，发送 4 TRX。新钱包转账，发送 8 TRX。批量工作，发送更多。下面的代码使用
TRX_AMOUNT 变量，便于在一个地方修改。

1. 设置

import os, requests
from tronpy import Tron
from tronpy.keys import PrivateKey, keccak256
from coincurve import PrivateKey as CCKey # tronpy already depends on coincurve
client = Tron() # mainnet — pass HTTPProvider(api_key=...) to avoid rate limits
priv = PrivateKey(bytes.fromhex(os.environ['TRON_PRIVATE_KEY']))
sender = priv.public_key.to_base58check_address()
API = 'https://api.tronnrg.com'
ADDR = 'TFqUiCu1JwLHHnBNeaaVKH7Csm4aA3YhZx' # API payment address
USDT = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t'
2. 发送 TRX
发送付款
TRX_AMOUNT = 4 # Linear: 16,250 energy per TRX. Min 4, max 1000.
# 4 → 65k (standard) · 8 → 130k (new wallet) · 40 → 650k (10 transfers)
payment = (
client.trx.transfer(sender, ADDR, TRX_AMOUNT * 1_000_000)
.build().sign(priv).broadcast()
)
print('Payment tx:', payment.txid)
3. 领取委托能量
领取委托
# Sign: proves you are the sender. Must equal TronWeb signMessageV2 exactly:
# keccak256("\x19TRON Signed Message:\n" + len + msg), secp256k1, v = rec + 27.
def sign_message_v2(message, priv):
msg = message.encode()
prefix = b"\x19TRON Signed Message:\n" + str(len(msg)).encode()
digest = keccak256(prefix + msg)
raw = CCKey(priv.to_bytes()).sign_recoverable(digest, hasher=None)
return '0x' + (raw[:64] + bytes([raw[64] + 27])).hex()
msg = f"{payment.txid}:{sender}"
sig = sign_message_v2(msg, priv)
delegation = requests.post(f"{API}/delegate", json={
'tx_hash': payment.txid,
'delegate_to': sender,
'signature': sig,
}).json()
if delegation.get('error'):
raise Exception(delegation['message'])
print('Energy delegated:', delegation['energy']) # TRX_AMOUNT × 16,250
4. 发送 USDT
发送 USDT
recipient = 'TRecipientWallet'
contract = client.get_contract(USDT)
tx = (
contract.functions.transfer(recipient, 10 * 1_000_000)
.with_owner(sender).fee_limit(50_000_000)
.build().sign(priv).broadcast()
)
print('USDT sent:', tx.txid)
错误处理
错误处理
result = requests.post(f"{API}/delegate", json=payload).json()
if result.get('error'):
err = result['error']
if err == 'payment_verification_failed':
pass # Payment not yet indexed on-chain. Wait 3s and retry.
elif err == 'hash_already_used':
pass # Already claimed. Do not retry.
elif err == 'signature_mismatch':
pass # Sender of TRX != signer of the message. Sign with the same key.
elif err == 'delegation_failed':
pass # Provider could not deliver. Retry or contact support with result['ref'].
完整示例
将此代码复制到文件中，设置 TRON_PRIVATE_KEY 环境变量，然后运行。该脚本会发送 TRX、签名、重试领取委托能量，然后发送 USDT。

始终包含签名。 它证明您是发送 TRX 的钱包。没有它，API 会以
missing_signature 拒绝请求。
