Metamask: How to add custom networks

The advantage of creating a Metamask wallet, in addition to have full control of your private key, is being able to add other networks.

In this example, you will add the BEP20 network, for this, you must first display the list of "Ethereum Mainnet" and click the "Add Network" button:

This will redirect you to the Metamask settings to set the required configuration:

BEP20 Network
