Deciphering Main Network vs Test Network with Metamask: A Step-by-Step Guide

As a Metamask user, you are probably used to navigating your cryptocurrency wallet in both mainnet and testnet environments. However, understanding the differences between the two can be crucial for developing and testing projects that require seamless integration with both networks.

In this article, we will dive into the process of determining whether your project is running on mainnet or testnet using Metamask.

Why Check if Your Project is Mainnet or Testnet?

Before we dive in, let’s quickly review why this matters:

• 
  Mainnet vs Testnet: The mainnet is the primary network used for legitimate cryptocurrency transactions. It is the “real” thing, not a simulation. On the other hand, testnets are used for testing and development purposes before being deployed to live networks.

• 
  Security Risks: Mainnet environments are more secure than testnets due to the higher transaction volume and limited access controls.

• 
  Compatibility Issues: Using a mainnet-compatible wallet in a testnet environment may cause compatibility issues or even errors.

Step by Step Guide: Check if your project is running on mainnet or testnet

To determine if your project is running on mainnet or testnet using Metamask, follow these steps:

1. Open Metamask and go to Settings

Open the Metamask wallet on your device, go to
Settings and go to
Network.

2. Check the status of the "Goerli" network

In the network settings, look for the network name. If it is listed as
Goerli Testnet



, you are using a testnet.

3. Check the network type (optional).

If you want to confirm whether your project is running on mainnet or testnet, you can check the network type by going to
Network >
Network Details >
Network Type.

• If you are listed as
  Goerli Mainnet, you are indeed running on Mainnet.

• Otherwise, you may be running a testnet. However, keep in mind that even if your project is not technically running on testnet, the network type may still be displayed as "Testnet" due to limitations in Metamask's testing capabilities.

4. Consider using a third-party tool

For the most accurate and reliable results, consider using third-party tools such as:

• 
  Metamask's Built-in Testnet Checker - This tool allows you to check the network status of your project without connecting directly to the testnet.

• 
  Etherscan's Mainnet/Testnet Checker
  
  
  
  : This tool provides an easy way to check whether your project is running on mainnet or testnet.

While these tools can provide more detailed information, keep in mind that even with third-party tools, it is still essential to understand how to identify and navigate between mainnet and testnet environments using Metamask.
