The above describes how to automatically generate wallets in batches. Once completed, we have a wallet that can automatically interact. But there must be eth in the wallet for gas to support interaction. How to automatically transfer money to each wallet?
Next, we introduce a simple example of using Python to implement batch operations and optimization. In this example, we will implement a batch transfer operation based on Ethereum. We will use the Web3.py library for implementation. Please note that this example is only a reference, and actual application needs to be adjusted and optimized according to specific circumstances.
First, make sure you have the Web3.py library installed:
pip install web3
Next, we create a Python file called "batch_transfer.py" and write the following code:
Import the required libraries:
from web3 import Web3, HTTPProvider
from web3.middleware import geth_poa_middleware
import json
Configure Web3.py:
# Initialize Web3 object w3 = Web3(HTTPProvider('https://mainnet.infura.io/v3/YOUR_INFURA_API_KEY')) # Add geth_poa_middleware to make it applicable to the Proof of Authority chain w3.middleware_onion.inject(geth_poa_middleware , layer=0)
Set batch transfer parameters:
#Transferer’s private key
private_key = 'YOUR_PRIVATE_KEY' #Transferer’s address
sender_address = w3.eth.account.privateKeyToAccount(private_key).address#Receiveraddress and transfer amount (unit: wei)
receivers = [ {'address': '0xReceiverAddress1', 'amount': w3.toWei(1, 'ether')}, {'address': '0xReceiverAddress2', 'amount': w3.toWei(0.5, 'ether' )} ] # Ethereum contract address
eth_address = '0x000000000000000000000000000000000000000' # Get the current gas price
gas_price = w3.eth.gasPrice
Construct a batch transfer transaction:
# Build batch transfer transactions
transactions = []
for receiver in receivers:
transaction = { 'to': receiver['address'], 'value': receiver['amount'], 'gas': 21000, # The gas limit for transfer operations
'gasPrice': gas_price, 'nonce': w3.eth.getTransactionCount(sender_address), }
transactions.append(transaction)
Sign and send bulk transfer transactions:
# 签名并发送批量转账交易 transaction_hashes = [] for transaction in transactions: signed_transaction = w3.eth.account.signTransaction(transaction, private_key) transaction_hash = w3.eth.sendRawTransaction(signed_transaction.rawTransaction) transaction_hashes.append(transaction_hash.hex()) print(f"Transaction sent: {transaction_hash.hex()}")
This example shows how to implement a batch transfer operation based on Ethereum using Python and the Web3.py library. In actual applications, you may need to adjust the code according to actual needs, such as supporting token transfers, dynamically adjusting gas prices, etc. In addition, attention needs to be paid to the confidentiality of private keys and error handling.
