How to view testnets in MetaMask

aviso

Testnet funds do not have any real-world value. If someone is trying to convince you otherwise, you might be getting scammed. See our article on testnet ETH scams for more information.

You can toggle the ability to show fiat values for testnets on/off in your MetaMask settings, on both Extension and Mobile. This feature is off by default.

If you want to use the Ethereum testnet Sepolia, or previously added testnets for other networks:

1. Click the menu in the top right-hand corner and select 'Networks'

2. Scroll down and toggle 'Show test networks' at the bottom of the network list

3. You can edit testnet details here by clicking the 3 vertical dots next to a network and selecting 'Edit'

You can also add a new testnet by clicking 'Add a custom network' on this screen.

Alternatively, on Extension you can configure whether testnets are displayed and converted to fiat values by going to Settings > Advanced.
