Small article to share with you a very nice tool to import chains on Metamask. Usually when you import chains, you have to set up the rpc and look for the right coordinates.
Sometimes it's boring and there with this tool, you have all the compatible EVM chains, the tesnets.
This tool is called "Chainlist", I put the link in description:

This tool is quite easy to use. You just have to connect your wallet.

Once connected, you just have to select the network you want to add to Metamask. Then you click on "add to Metamask".

Then you approve and it's ok. You have added a new network to Metamask in a few clicks.

I'll let you see, you have a lot of networks on offer.
