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.

In alternativa, puoi anche cercare la rete da aggiungere nella barra di ricerca.

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'. Verrà visualizzato un elenco di reti a cui sei già connesso.

  1. Click 'Add a custom network'.

Adding or editing RPC URLs

L'abbreviazione RPC sta per chiamata di procedura remota, un insieme di protocolli che consentono a un client (come MetaMask) di interagire con una 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.

nota

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'.

MetaMask extension dropdown menu 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

Tieni presente che non conserviamo le informazioni di rete su Chainlist. Assicurati che i dettagli della rete siano accurati prima di aggiungerli.

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. Vai sul sito Chainlist all'indirizzo chainid.network.

  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:

  1. Ora usa la barra di ricerca per trovare la rete a cui vuoi connetterti. Una volta trovata, fai clic sul pulsante "Aggiungi chain".

Chainlist add chain button

  1. MetaMask entrerà in azione e ti presenterà un menu di approvazione. Click 'Confirm' to proceed.
