thanks for the feature request, @hesterbruikman is that some token we would like to support?

Depends on what dapps have been deployed on Matic and whether they are commonly used among our user base. I suspect Decentraland is or will be available on Matic (don't know for sure), but that's a dapp that's not too convenient on mobile. Other than that, I don't know of dapps deployed to call for adding the network by default.

@DaniellMesquita do you know of other dapps deployed on Matic? Anything specific you're looking to use on the network?

@cammellos Regardless, we should check if manual entry works. Would be good if someone more familiar with adding networks can take a look. I'm running into the error: Specified network id doesn't correspond to network id by RPC url I have no clue what the network id should be. Tried 137 provided here as well as some other combinations. Always the same error.
