How to add a custom network

MetaMask lets you connect to many different networks. Before adding one manually, check whether it’s already supported by default.

Default networks

Ethereum • Linea • Base • Solana • Bitcoin • Polygon • BNB Chain • Arbitrum • OP • Sei • Avalanche • zkSync Era

On both Mobile and Extension, you can easily add several networks with just a click:

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

MetaMask extension dropdown menu networks

  1. 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.

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:

  1. Click on the menu in the top right and select 'Networks'. 이미 연결된 네트워크 목록이 표시됩니다**.**

  1. Click 'Add a custom network'.

Adding or editing RPC URLs

RPC라는 이니셜은 클라이언트(MetaMask 등)가 블록체인과 상호 작용할 수 있도록 하는 프로토콜의 집합인 원격 프로시저 호출(Remote Procedure Call)을 나타냅니다. 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.

참고 사항

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.

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

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

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

  1. Enter the URL, nickname, and 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

**MetaMask는 체인리스트에 있는 네트워크 정보를 유지 관리하지 않습니다. 네트워크 세부 정보를 추가하기 전에 해당 정보가 정확한지 확인하세요.

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

  1. chainid.network를 통해 체인리스트 사이트로 이동하세요.

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

Chainlist connect to site button

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

Chainlist connected address

  1. 이제 검색창을 사용하여 연결할 네트워크를 찾으세요. 찾으면 '체인 추가'를 클릭하세요.

Chainlist add chain button

  1. 이제 MetaMask가 작동하기 시작하고 승인 메뉴가 표시됩니다. Click 'Confirm' to proceed.
