Seems like a feature that Keybase could implement (this can be a way for them to gain users, too); they already allow sending cryptocurrency to other users and they have the ability to authenticate based on online identities.

This would require that the sender and receiver both have keybase.

Yeah they could also allow temporary session like discord does. Discord lets you join and chat on a server without having to permanently make an account via invite link.
