I've come to appreciate Metamask as well. Haven't used it that much (only recently to take a position in [KOIN](https://koinos.io/), but I really like what I've seen!

Isn't keychain trying to do more or less all the same things on top of being a log-in option for most Hive-based interfaces? Or what's the difference?

Edit: I will have to put some money into CUB if only to support local efforts and also try it out :)
