trc20合约转账代码

以下是一个基于Python的TRC20合约转账代码示例：

from web3 import Web3
import json

# 连接到以太坊节点
w3 = Web3(Web3.HTTPProvider('https://api.trongrid.io'))

# 加载合约ABI
with open('contract_abi.json', 'r') as f:
    abi = json.load(f)

# 创建合约实例
contract_address = '0x1234567890123456789012345678901234567890'
contract = w3.eth.contract(address=contract_address, abi=abi)

# 设置转账参数
recipient_address = '0x0987654321098765432109876543210987654321'
amount = 1000000000  # 转账数量，单位为wei

# 获取当前账户的nonce值
nonce = w3.eth.getTransactionCount('0x0123456789012345678901234567890123456789')
# 构造交易
tx = contract.functions.transfer(recipient_address, amount).buildTransaction({
    'nonce': nonce,
    'gasPrice': w3.toWei('1', 'gwei'),
    'gas': 100000,
})

# 签名交易
signed_tx = w3.eth.account.signTransaction(tx, private_key='0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef')

# 发送交易
tx_hash = w3.eth.sendRawTransaction(signed_tx.rawTransaction)

# 等待交易确认
tx_receipt = w3.eth.waitForTransactionReceipt(tx_hash)

# 打印交易结果
print('Transaction receipt:', tx_receipt)

需要注意的是，上述代码中的`contract_abi.json`文件需要根据具体的TRC20合约进行修改。此外，还需要替换`contract_address`、`recipient_address`和`private_key`等参数为实际值。
