根据提供的交易信息，我们可以构建如下的Python自动化交易参数：

{
    "to": "0x14d574bf73afc594b0df6c47c2d026675095a751",
    "value": 200000000000000000,
    "gas": 100000,
    "gasPrice": 104129862654,
    "nonce": 38,
    "data": "0xe9e05c4200000000000000000000000014d574bf73afc594b0df6c47c2d026675095a75100000000000000000000000000000000000000000000000000c3663566a580000000000000000000000000000000000000000000000000000000000186a000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000a0000000000000000000000000000000000000000000000000000000000000000"
}

其中，参数含义如下：

  • to: 目标合约地址
  • value: 要发送的ETH数量，单位为wei
  • gas: 本次交易所能使用的最大Gas数量
  • gasPrice: 本次交易每个Gas的价格，单位为wei
  • nonce: 交易发送方的账户当前的nonce值
  • data: 交易数据，包括方法ID和参数列表

需要注意的是，Gas Limit和Gas Fees的值在这里并没有直接使用，而是根据交易信息计算出来的。如果您有其他交易信息，可以根据类似的方法计算出上述参数。

再对下面的代码交易参数进行优化
for i in range(self.start_index,self.df_data.shape[0]):
address = self.df_data.loc[i,'address']
print(address)
private_key = self.df_data.loc[i,'private_key']

        # 获取钱包余额
        balance_wei = self.web3.eth.get_balance(address)
        balance_eth = self.web3.fromWei(balance_wei, 'ether')
        self.bridge_log(f'当前第{i+1}个钱包余额为{balance_eth}')

        # 检查余额是否足够完成跨链交易
        base_fee = self.web3.eth.get_block('latest')['baseFeePerGas']
        gas_limit = 100000
        amount_wei = self.web3.toWei(float(self.amount) , 'ether')
        max_fee = base_fee * gas_limit + amount_wei
        if balance_wei < max_fee:
             self.bridge_log(f'当前第{i+1}个钱包余额不足以完成跨链')
             continue
        value_str = str(amount_wei* random.uniform(0.9, 1) )
         # 构建交易并发送
        nonce = self.web3.eth.get_transaction_count(address)
        # 获取函数的输入参数
        inputs = [value_str, 40000]
        # 获取合约的ABI参数
        contract_abi = self.web3.eth.contract(address=contract_address, abi=my_contract_abi).abi
        # 构建交易参数
        tx = {
            'nonce': nonce,
            'gas': gas_limit,
            'type': 2,
            'maxFeePerGas': max_fee,
            'maxPriorityFeePerGas': base_fee,
            'to': contract_address,
            'value': value_str,
            'data': self.contract.encodeABI(fn_name='depositETH', args=inputs, data=contract_abi),
            'chainId': 5
        }
        txn = self.contract.functions.depositETH(value,40000).build_transaction(tx)

        signed_tx = self.web3.eth.account.sign_transaction(txn, private_key)
        tx_hash = self.web3.eth.send_raw_transaction(signed_tx.rawTransaction)
        self.bridge_log(f'第{i+1}个钱包发起跨链，交易哈希为{Web3.toHex(tx_hash)}')



        # 等待随机时间间隔
        rand_time = random.randint(0, 10)
        time.sleep(rand_time)

    # 发送结束消息到主进程
    self.pip.send({'task':END_BRIDGE})

根据提供的代码，我们可以对交易参数进行如下优化：

  1. 首先，Gas Limit可以根据实际情况进行动态调整，以尽可能地节约手续费。比如可以通过调用estimateGas方法来获取函数执行所需的Gas Limit，然后将其乘以一个安全系数，作为本次交易的Gas Limit。

  2. 其次，Gas Price可以通过调用eth.gas_price()方法来获取当前的平均Gas Price，以便我们能够更加准确地计算出最小可接受的交易费用。

  3. 另外，由于交易使用的是EIP-1559协议，因此可以使用maxFeePerGas和maxPriorityFeePerGas两个参数来控制交易费用。其中，maxFeePerGas表示本次交易所能接受的最大交易费用，而maxPriorityFeePerGas则表示交易矿工所能获得的最小交易费用，两者之和即为本次交易的总交易费用。可以根据实际情况进行调整，以便尽可能地节约手续费。

基于上述优化，我们可以修改代码如下：

for i in range(self.start_index,self.df_data.shape[0]):
    address = self.df_data.loc[i,'address']
    print(address)
    private_key = self.df_data.loc[i,'private_key']

    # 获取钱包余额
    balance_wei = self.web3.eth.get_balance(address)
    balance_eth = self.web3.fromWei(balance_wei, 'ether')
    self.bridge_log(f'当前第{i+1}个钱包余额为{balance_eth}')

    # 检查余额是否足够完成跨链交易
    amount_wei = self.web3.toWei(float(self.amount), 'ether')
    estimated_gas = self.contract.functions.depositETH(amount_wei, 40000).estimateGas({'from': address})
    max_fee_per_gas = self.web3.eth.gas_price() * estimated_gas
    max_fee = max_fee_per_gas * 1.5 # 安全系数为1.5
    if balance_wei < max_fee:
        self.bridge_log(f'当前第{i+1}个钱包余额不足以完成跨链')
        continue

    value_str = str(int(amount_wei * random.uniform(0.9, 1)))

    # 构建交易并发送
    nonce = self.web3.eth
