Custom networks missing after reinstalling or restoring from Secret Recovery Phrase

When you reinstall MetaMask, custom networks need to be re-added. This is because MetaMask essentially considers your wallet to be a completely new instance of the app, and will not retain any of the data that was previously stored locally — custom networks being one example.

Using a local node

Once you have your own node up and running, you can connect MetaMask to it.

Verificar los datos de redes personalizadas

Cuando un sitio web solicita que agregue una red personalizada a MetaMask, se le presenta la información que MetaMask utilizará para interactuar con aquella red. En MetaMask se realizará una validación básica de esta información, y le avisará si algo parece mal o fuera de lo normal. En MetaMask también se evitará que la misma red se agregue más de una vez. Aunque MetaMask no verifica las redes personalizadas, incluso si la validación de MetaMask es correcta, la red podría ser maliciosa o tergiversada por el sitio web que la solicitó.
