Create a new Ethereum Account using Python

Introduction

In the world of blockchain and cryptocurrency, Ethereum is one of the leading platforms for decentralized applications (dApps). To interact with Ethereum, you often need an Ethereum account. This article will guide you through creating an Ethereum account and connecting to the Ethereum testnet using Python.

Prerequisites

Before we get started, make sure you have Python installed and the following Python packages installed.

• web3 - A Python library for Ethereum interaction.
• eth-account - A Python library for Ethereum account management.
• An alchemy account - We will use alchemy to connect to the Ethereum network

Step 1. Install Required Libraries

Open your terminal and install the necessary libraries using pip.

pip install web3 eth-account

Step 2. Setup Alchemy API Access

Go to the Alchemy website (https://docs.alchemy.com/) and create an account if you don't have one.

After logging in, Click on Apps.

Now create a new app.

Choose the Ethereum network (Goerli for testnet).

Click on API Key and copy the Alchemy URL. 

Step 3. Writing the Python Script

Create a Python script with the code. This script connects to the Ethereum (Goerli) testnet using Alchemy's API.

from web3 import Web3
from eth_account import Account

# Define your Infura API URL for Polygon (Matic) testnet
alchemy_url = "https://eth-goerli.g.alchemy.com/v2/RoZMa3Z8CWHE_ofXXXXXCkB7fGW3zBP3"

# Connect to the Ethereum network (Ethereum Goerli Testnet Explorer)
w3 = Web3(Web3.HTTPProvider(alchemy_url))

if w3.is_connected():
    # Generate a new Ethereum account (public-private key pair))
    account = Account.create()

    # Print the account address and private key
    print(f"Address: {account.address}")
    print(f"Private Key: {account.key.hex()}")

    # Note: This code is for the Ethereum Goerli Testnet Explorer. Make sure to adjust the URL for testnets if necessary
else:
    print("Not connected to the Ethereum network.")
    

Output

We can also check this address on (https://goerli.etherscan.io/) to make sure that the address is generated.

Conclusion

In this article, we've covered the process of creating an Ethereum account and connecting to the Ethereum (Goerli) testnet using Python. With your Ethereum account, you can start interacting with Ethereum-based applications and services, such as DeFi platforms, NFT marketplaces, and more. Just remember to keep your private key secure and never expose it to the public.
