Step 1: Open Metamask Extension

Before you can add a new network to Metamask, you need to open the Metamask extension in your web browser. The extension is available for Chrome, Firefox, Opera, and Brave browsers.

For Chrome and Brave Users:

If you are using Chrome or Brave, look for the Metamask icon in the top-right corner of your browser toolbar. It looks like a fox’s head with a mask. Click on the icon to open the Metamask extension.

For Firefox Users:

If you are using Firefox, click on the hamburger menu in the top-right corner of your browser toolbar. From the dropdown menu, click on the Metamask icon to open the extension.

If you don’t see the Metamask icon in your browser toolbar, you may need to pin it. Right-click on the toolbar, select “Customize”, and drag the Metamask icon to your desired spot on the toolbar.

If you don’t have the Metamask extension installed, you can download it from the official Metamask website or from the respective extension stores for your browser.

Once you have opened the Metamask extension, you are ready to proceed to the next step of adding a new network to Metamask.

Step 2: Click on the Network Dropdown

Once you have successfully installed and opened Metamask, you will see a small fox icon in the top right corner of your browser. Click on the fox icon to open the Metamask extension.

After opening the extension, you will be taken to the Metamask main screen. Here, you will see various options and settings. Look for the network dropdown menu, usually located in the top center of the screen.

Click on the network dropdown menu to reveal a list of available networks. You will see options such as “Main Ethereum Network,” “Ropsten Test Network,” and others. This is where you can select the network you want to add to Metamask.

Make sure to choose the correct network that corresponds to the blockchain or network you want to connect to. For example, if you are adding a custom or private network, select the “Custom RPC” option.

If the network you want to add is not listed, you can select the “Custom RPC” option and manually enter the network’s details, such as the network name, URL, and chain ID. This allows you to add any compatible Ethereum network to Metamask.

Note: It is important to be cautious when connecting to custom or unfamiliar networks, as they may not have the same level of security and trust as the main Ethereum network.

Step 3: Select “Custom RPC”

Once you have opened your Metamask extension, you will see a small fox icon on the top right corner. Click on the icon to open the Metamask menu.

In the Metamask menu, you will see a list of networks. By default, the “Main Ethereum Network” is selected. To add a new network, select “Custom RPC” at the bottom of the list.

A new dialog box will appear, allowing you to enter the details of the new network you want to add.

In the “Network Name” field, enter a name for the network. This can be anything you want, but it’s recommended to use a name that identifies the specific network you are adding.

In the “New RPC URL” field, enter the RPC URL for the network. This URL contains the endpoint for the network’s blockchain API. Make sure the URL is correct and up to date.

You can also enter the chain ID for the network in the “Chain ID” field, if you know it. This is an optional field and can be left blank.

Once you have entered all the details, click on the “Save” button to add the new network to Metamask.

Congratulations! You have successfully selected “Custom RPC” and added a new network to Metamask. You can now use this network to interact with decentralized applications and perform transactions.

Network Name

Enter a unique name for the network. This could be the name of the blockchain, organization, or project that the network is associated with. Make sure to choose a name that is easy to remember.

New RPC URL

Copy and paste the RPC URL for the network into this field. The RPC URL is the endpoint that Metamask will use to connect to the network. You can usually find this information on the network’s website or documentation.

Note: Make sure the RPC URL is accurate and up-to-date, as an incorrect URL can prevent Metamask from functioning properly.

ChainID

The ChainID is a unique identifier for the network. It helps Metamask differentiate between different networks and ensure that transactions are sent to the correct chain. Double-check the ChainID provided by the network and enter it into this field.

Symbol

The Symbol refers to the currency or token symbol associated with the network. For example, “ETH” for Ethereum or “BNB” for Binance Smart Chain. Enter the symbol into this field.

Block Explorer URL

Add the URL for the block explorer associated with the network, if available. This will allow you to easily view transaction and block details directly from Metamask. If the network does not have a block explorer, you can leave this field blank.

Once you have filled in the network details, click on the “Save” button to add the new network to Metamask. You should now see the network listed in your network options and be able to select it when interacting with decentralized applications on that network.
