So I finally found this thing and am curious about it. Have you been using it? Seems there is a lot more to it than just our graphene based chains like Steem, Hive and Blurt. I even saw some thing about Whaleshares on there. I haven't dug too deep into it yet, but will be using it for Blurt, at least. Want to hear something funny? Of the 6 active extensions I have on my browser, 3 of them are 'keychains'.
