【问题描述】：

我试图在 Binance Smart Chain 中将交易从一个账户发送到另一个账户，但出现错误 ValueError: {'code': -32000, 'message': 'transaction type not supported'}

这是我的代码

from web3 import Web3

REF_ADDRESS = '0x5...'
MY_ADDRESS = '0xe...'
MY_PKEY = 'd...'
MAX_GAS_ETHER = 0.0005

web3 = Web3(Web3.HTTPProvider('https://bsc-dataseed.binance.org/'))

balance = web3.eth.get_balance(MY_ADDRESS)
gas_price = float(web3.fromWei(web3.eth.gas_price, 'ether'))
allowed_gas = int(MAX_GAS_ETHER/gas_price)
print(web3.fromWei(balance, 'ether'))

tx = {
    'from': MY_ADDRESS,
    'to': REF_ADDRESS,
    'value': web3.toWei(0.0001, 'ether'),
    'gas': allowed_gas,
    'type': 2,
    'chainId': web3.eth.chain_id,
    'maxFeePerGas': web3.toWei(5, 'gwei'),
    'maxPriorityFeePerGas': web3.toWei(2, 'gwei'),
    'nonce': web3.eth.get_transaction_count(MY_ADDRESS),
    }

tx_signed = web3.eth.account.sign_transaction(tx, MY_PKEY)
tx_hash = web3.eth.send_raw_transaction(tx_signed.rawTransaction)
tx_receipt = web3.eth.wait_for_transaction_receipt(tx_hash)

请帮我弄清楚我做错了什么

【解决方案1】：

好吧，我通过更改交易值解决了这个问题

tx = {
    'from': MY_ADDRESS,
    'to': REF_ADDRESS,
    'value': web3.toWei(0.0001, 'ether'),
    'gas': allowed_gas,
    'type': 2,
    'chainId': web3.eth.chain_id,
    'maxFeePerGas': web3.toWei(250, 'gwei'),
    'maxPriorityFeePerGas': web3.toWei(2, 'gwei'),
    'nonce': web3.eth.get_transaction_count(MY_ADDRESS),
    }

到

tx = {
    'nonce': web3.eth.get_transaction_count(MY_ADDRESS),
    'to': REF_ADDRESS,
    'value': web3.toWei(0.001, 'ether'),
    'gas': allowed_gas,
    'gasPrice': web3.eth.gas_price
}
