Would be great to have a preconfigured network for Polygon and other common ethereum sidechains/l2s. It doesn’t have to show up in the dropdown by default, but perhaps it can be a pre-configured network you can “add”.
Ethereum is too expensive for most normal people now. New people can’t onboard and experiment without $40 transaction fees which makes it impossible to just try stuff out like in the old days. This threatens the entire ecosystem by shutting out all but the richest people and causes people to move to alternate chains. Polygon and other sidechains have almost 0 gas fees and are perfect for new users, but its extremely hard to onboard into these networks. One of the reasons is because you have to manually configure the network by hand in wallets like Metamask, which is scary even for seasoned technical people, much less the lay user.
Put Polygon and some other popular networks as preconfigured settings that can be selected when you “add a new network”. This will make it much easier for people to onboard into cheaper sidechains where new users can play around with defi and understand crypto.
Increased adoption in the Ethereum/EVM compatible ecosystem. Increased Metamask success/usage
