A quick primer/refresher on how to add the main blockchains to your MetaMask or WebWallet! Navigate to Custom RPC in MetaMask and input the info for your desired network and you’ll be surfing the Ethereum, BSC or MATIC blockchains in no time!

Here's a quick animation on the process:
Hope you guys found that useful! There are many more emerging blockchains to keep an eye on and we’ll be exploring them in due course. Isn’t it exciting? Finally all the theory is turning into actual apps, so we better be prepared to use them as we bridge the gaps between the various chains.
TL;DR:
- Custom networks are Ethereum compatible networks.
- Gas is determined by a network’s demand, not by MetaMask or any wallet provider.
- Different networks have different gas fees based on their design and demand.
- Sidechains and Layer-2 solutions are types of custom networks you can add to MetaMask. They may have lower gas fees at the expense of decentralization or security.
- Sidechains and Layer-2 solutions mainly differ on how their blocks are validated.
- Example of custom networks are Binance Smart Chain, Polygon (MATIC), Huobi ECO Chain, Avalanche, and xDai.
