Doing what? Allowing payments within different social media platforms with 1 account? Don't know any, its damn well thought.
I can send my friends money in many ways with my phone already, everyone's doing it on my campus, seems like the only unique thing about this is the crypto.
But you cant send money on fb, whatsapp, reddit, twitter, snapchat, instagram and others with one account. social media has the most users, if it catches on your campus will be using this if they use multiple social media platforms. Such thing afaik doesnt exist yet, why do u think there is interest for this innovation. The crypto and fiat world has never seen such technology.
No you can't, i just downloaded the app, its fb and twitter only! Without the need? and how did u measure this? Also its pretty new, but trust me paying within social media will be the future.
Again, paykey allows you to make payments within different social medias with 1 account, changetip only offers fb and twitter, no whatsapp, no snapchat, no instagram no reddit (from the app), no pinterest, no others.
