How to add a network

MetaMask lets you connect to many different networks. Some are pre-enabled while others appear under 'Additional networks' in the network selector and can be added with the '+' icon. Check whether the network is already supported before adding it manually.

Supported networks

Ethereum • Bitcoin • Linea • Base • Solana • Tron • Polygon • BNB Chain • Arbitrum • Monad • Robinhood Chain • OP • Sei • Avalanche • zkSync Era • MegaETH • HyperEVM • Arc • Tempo

Arc and Tempo don't use a chain-native token for gas: Arc uses USDC, and Tempo accepts pathUSD, USDC.e, or USDT0.

Adding a popular network

On both Mobile and Extension, you can easily add several networks at the same time:

• Extension
• Mobile

1. Click the 'All networks' dropdown from the 'Tokens' tab.

2. Click 'Manage networks'.

3. Scroll to the bottom of the list to view popular networks. Click the plus button to add your chosen network(s).

4. You can also search for a network by name or by chain ID at the top of the list.

1. Tap 'Tokens' from the home screen.

2. Tap the network dropdown at the top of the screen, which is set to 'Popular networks' by default.

3. Scroll to the bottom of the list to view popular networks. Tap the plus button to add your chosen network(s).

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 the 'All networks' dropdown from the 'Tokens' tab.

2. Click 'Manage networks'.

3. Click 'Add a custom network' at the bottom of the screen.

4. Enter the network details and click 'Save'.

1. Tap 'Tokens' from the home screen.

2. Tap the network dropdown at the top of the screen, which is set to 'Popular networks' by default.

3. Tap the 'Custom' tab.

4. Tap 'Add a custom network'.

5. Enter the network details and tap 'Save'.

Adding or editing RPC URLs

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 to Ethereum, Linea, Base, Arbitrum, or BNB Smart Chain RPC will disable Smart Transaction capabilities like MEV protection. To re-enable this, you'll need to switch back to the default RPC URL from network settings.

• Extension
• Mobile

1. Click the 'All networks' dropdown from the 'Tokens' tab.

2. Click 'Manage networks'.

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

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

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

1. Tap 'Tokens' from the home screen.

2. Tap the network dropdown at the top of the screen, which is set to 'Popular networks' by default.

3. Click the 3 dots by the network you want to edit and tap 'Edit'.

4. Select the RPC URL dropdown field and click 'Add RPC URL'.

5. Enter the URL, nickname, and click 'Save' 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' in the top right to do so.

When successful, the address of our selected account will replace the 'Connect' 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 'Confirm' to proceed.

1. Head to the Chainlist site using the MetaMask explore tab.

When you're in the explore tab, you can search for the site using the search bar or you can tap the browser icon in the top right and navigate to https://chainid.network.

2. On Chainlist, you need to connect your MetaMask. When your wallet is connected, the selected account address will be displayed where the 'Connect' button was. If you want to change the account, you can tap the account icon in the top right and select the account you want to use.

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.
