In the Ethereum blockchain, the role of the Testnet is fundamental. An Ethereum Testnet is basically an identical copy of a blockchain network. Its sole purpose is to perform tests of new attributes and dimensions. A common question that most blockchain developers ask today is, “How to get Ethereum for the testnet?” This is an important question that you need to find an answer to when working within an Ethereum network. Ethereum blockchain developers rely on Ethereum Testnet to test protocol upgrades. That’s not all! By using Ethereum Testnet, it is possible to test smart contracts before they are actually deployed to users. With the help of Aenvil and Python, you have the ability to run an Ethereum Testnet yourself. So, you don’t need to go through the typical hassles of using an official Testnet. However, the main question that you need to answer is related to how to create Ethereum Testnet. Let’s explore the steps that can help you create Ethereum Testnet with Anvil and Python.
Steps to Run Your Ethereum Testnet Using Anvil and Python
If you want to build an Ethereum testnet with Anvil and Python, you need to take a systematic and step-by-step approach. The steps below can serve as the ultimate roadmap in your journey towards building an Ethereum testnet. You don’t have to feel overwhelmed as the simple instructions can guide you to run your Ethereum testnet efficiently.
Step 1 – Installing and Running Anvil
The first step you need to take is to install and run Anvil. If you have limited knowledge of Anvil, you should know that it is a component of the Foundry toolchain. This is a basic step that can lay the foundation for creating Ethereum Testnet.
Are you wondering how to develop Ethereum with Anvil? If so, you should keep in mind that the Anvil application allows you to get started with Ethereum development in a simple way. There are a few sub-steps that you need to follow to progress in your first step:
-
Sub-step 1 – Foundry installation
You need to install Foundry in order to use its anvil component. To do this, you need to open the terminal and run the appropriate command. Once the installation process is successfully completed, you need to source Foundry using the necessary command.
-
Substep 2 – Installing the Anvil
After installing the Foundry toolchain, you need to focus on Anvil. You need to install and run Anvil so that you can get started with your local Ethereum node. You can be sure that Anvil is running if you see the output indicating the same. Additionally, the output should also encompass other details such as the Remote Procedure Call (RPC) endpoint.

Step 2 – Connect to the local Anvil node
Now it’s time to focus on the next step after completing the first step. The second step is to establish a connection with the local Anvil node. At this point, it is essential that you keep in mind to use Python as your programming language. To interact with the local Anvil node, you can use web3.py.
Web3.py is a Python library that you can use to interact with Ethereum. Developing Ethereum with Python will make your journey easier if you already have some prior knowledge of the programming language. However, if you want to use other programming languages such as Rust, you can do so.
While keeping the local Anvil node from the previous step running, you need to follow the substeps below. However, it is important to keep in mind that you need to perform the operations below in a new or separate terminal window.
-
Substep 1 – Installing web3.py
The fundamental step you need to do is to install web3.py.
-
Substep 2 – Linking with the Anvil Local Note
Once you have successfully installed the Python library, it is time to connect to the Anvil node. To do this, you need to create a Python script. This is undoubtedly a key process that can help you establish a connection with the Anvil node.
When you run the script, if everything has been done perfectly and correctly, you can see the message “Connected to Anvil”. This message will be displayed in your terminal. However, if you are unable to establish the connection, you need to recheck the Anvil node. This step is crucial to ensure that the local Anvil node is working properly or not. Moreover, it will also help you see if the Anvil node is logging the output efficiently or not. Here are some key things to keep in mind if you want to build Ethereum Testnet with Anvil and Python.

Step 3 – Deployment and interaction with a smart contract
Step 3 is arguably one of the most important steps when running your own Ethereum testnet using Anvil and Python. At this point, you should focus on the actual deployment aspects. There are a few sub-steps that can guide you to navigate step 3 efficiently.
-
Substep 1 – Create a smart contract
You should start by developing a simple smart contract. It is essential to keep in mind that the purpose of the smart contract is only for testing purposes, so it should be simple. You can use a new name for it and add the appropriate Solidity code.
-
Substep 2 – Using Forge to compile and deploy the contract
At this point, you need to compile and deploy the smart contract. You can do this using Forge. First, you need to open the terminal. Then, you need to browse to the directory containing the newly developed smart contract. After running the necessary command, you will see that the smart contract is deployed on the Anvil node. One important thing that you need to keep in mind is that you need to note down the contract address. The contract address is the one that was generated as output by Forge.
You have to remember that when a smart contract deployment takes place in the blockchain, an address has to pay the necessary gas. The specific case is for the local Anvil node and the local testnet. So there is an option to use one of the default accounts developed by Anvil. An important thing to consider is that the account you select must be uniform across all Anvil runs. However, you may need to use a different address.
-
Substep 3 – Interact with the smart contract using web3.py
Now you need to develop a new Python script that will handle interacting with the contract. During the deployment step, you need to make sure that you are using the actual address of the smart contract. This is an important thing to consider when you Create an Ethereum Testnet with Anvil and Python.
After running the script, you can see the output which shows the initial value as well as the generated value after incrementing.
