How to add a custom network RPC

MetaMask can access many more networks than just Ethereum mainnet: you can add any EVM-compatible network directly within your MetaMask, create Solana accounts, and browse non-EVM networks through Snaps.

The initialism RPC stands for remote procedure call, a set of protocols that allow a client (such as MetaMask) to interact with a blockchain. You can add multiple RPC URLs for a single network and edit the default RPC URL from your list of networks in both Extension and Mobile settings.

note

Adding a custom RPC URL will disable Smart Transaction capabilities. To re-enable this, you'll need to switch back to the default RPC URL from network settings.

Adding a popular network

On both Mobile and Extension, you can easily add several networks with just a click. You can find this using the following steps:

• Extension
• Mobile

1. Click on the menu in the top right and select 'Networks'.

2. Scroll down until you see the 'Additional networks' section and click 'Add' next to the network you wish to add.

Alternatively, you can also search for the network to add in the search bar.

1. Tap the network selector at the top of the screen. (Alternatively, you can tap the gear icon to access settings, and then go to 'Networks'.)

2. Here you'll see a list of networks that you've already added. Tap the "Add Network" button at the bottom of the screen.

3. You should now see a list of networks you can add under the "Popular" tab, as shown below.

4. When you choose to add one of them, you'll be prompted to confirm your selection and then get the option to switch immediately to that network. All done!

   

Adding a network manually

If you don’t see a desired network in the list, you can follow these instructions to establish the network connection manually:

• Extension
• Mobile

1. Click on the menu in the top right and select 'Networks'. This will display a list of networks that you've added already.

2. Click 'Add a custom network'.

3. A screen will appear where you can enter the details of the network you wish to add. Click 'Save' to add the network.

1. Tap the network selector at the top of the screen.

2. Tap on "Add Network".

3. Switch to the "Custom networks" tab.

4. Fill in the network's details:

After performing the above steps, you can see the custom network in the network selector.

Adding or editing RPC URLs

You can add multiple RPC URLs for a single network and edit the default RPC URL from your list of networks in both Extension and Mobile settings.

• Extension
• Mobile

1. Click on the menu in the top right and select 'Networks'.

2. Locate the desired network you want to edit and click the 3 dots to edit.

3. Select the Default RPC URL dropdown field and click “Add RPC URL”.

4. Enter the URL, nickname, and save your configurations.

1. Tap the network selector at the top in the middle of your MetaMask to show the list of enabled networks
2. Click the 3 dots by the network you want to edit
3. Select the Default RPC URL downtown field and click “Add RPC URL”
4. Enter the URL, nickname, and click “Add URL” to save your configurations

You can now toggle between various RPC URLs when you want to switch providers. To delete any RPC URL, follow the same steps above and click on the trash bin icon to delete.

Networks across devices

Adding a network on one device does not mean it will appear on another device when accessing the same account. If you add it on Extension, it will not automatically be added to your MetaMask Mobile app yet, and vice versa.

Custom networks will also need to be re-added if you uninstall the browser extension or mobile app (after which you'd need to restore your wallet using your Secret Recovery Phrase).

Adding via Chainlist

Please note we do not maintain the network information on Chainlist. Make sure the network details are accurate before adding them.

For another way of adding networks to MetaMask, go to chainid.network, where you can connect MetaMask and add networks with a few clicks.

• Extension
• Mobile

1. Head to the Chainlist site at chainid.network.

2. Firstly, you'll need to connect your MetaMask to the site. Select 'Connect wallet' in the top right to do so.

When successful, the address of our selected account will replace the 'Connect wallet' button:

3. Now use the search bar to find the network you want to connect to. Once you've found it, click the button 'Add Chain'.

4. MetaMask itself will now spring into action, and will present you with an approval menu. Click 'Approve' to proceed.

5. This will be followed by a menu asking you whether you want to switch to the new network immediately. Confirm or reject this depending on your needs; either way, the new network will be added.

1. Head to the Chainlist site using the MetaMask in-app browser.

   

   When you're in the browser, you can either tap the address in the menu bar at the top and navigate to https://chainid.network or hit the magnifying glass in the toolbar at the bottom and search from there.

2. On Chainlist, you need to connect your MetaMask. Your currently selected account will be the one that's automatically connected, though you can easily swap by going back to your wallet view, changing the account, and heading back to Chainlist in the browser to connect.

   

   When your wallet is connected, the selected account address will be displayed where the 'Connect wallet' button was.

3. Next, find the network you want to connect to by searching. When you find the network, hit 'Add Chain':

   

4. Now you'll just need to approve the addition of the network.

   There will then be a subsequent option to confirm that you want to immediately switch to the new network. This step is optional, and you can easily change networks at any time regardless.
