Custom MetaMask networks are non-Ethereum networks but these networks are EVM (Ethereum Virtual Machine) compatible.
In other words, these networks are not based on Ethereum, but they are Ethereum. You may think about calling a MetaMask network as a relative or a sibling of Ethereum. That’s because they share numerous similar features with each other.
Since all these networks are based on Ethereum, you will be able to maintain the same address across different networks. This means you can have a single seed phrase, or a recovery phase, which you can use to access different networks and accounts.
How To Connect a Metamask Wallet to The Other Network
When you try to add a new MetaMask network, you will need to enter some information. That includes:
Network Name — You can select any name for the network. However, I encourage you to add a meaningful name, so that you can easily figure it out.
New RPC Rule — This would be a URL, which will act as the entry point into the Blockchain.
Chain ID — This is a unique ID number, which is provided by the Blockchain network that you interact with.
Currency Symbol — This is an optional parameter. You can pick an appropriate symbol from the ticker.
Block Explorer URL — This is also an optional parameter. It is a URL that you can use to access Block Explorer. If you wish to get detailed information with related to transactions, you may think about using this feature.
