Metamask đĻ and other multi-EVM wallets allow you to add networks manually, which is useful if the process of automatically adding a network fails for some reason or if you prefer to add networks manually.
At chainlist.org, you can find multiple networks and even multiple RPCs for the same chain.
Search for the network that interests you and add it automatically by connecting your wallet, or manually add the network to MetaMask using the data provided by the website itself.
The parameters you need to enter to add any EVM network are as follows:
Network Name: Network name, you can identify it however you want.
Network RPC URL: Networks usually have multiple entry points (RPC).
Chain ID: The number that identifies the network.
Symbol/Currency: BNB, ETH, MATIC...etc
Block Explorer (Optional): The link to the blockchain explorer.
