Is there a way to send "value" to users

Wondering if there is a way to set up the app so that you can send value to other users. Rather than messaging other users, I’m talking about sending them a unit of in-app currency (not actual money). I’ve read the threads about messaging but they don’t really address what I’m looking for. Essentially would like a simple page where you can send a unit of value to another user and also have a counter that acts as your bank, counting how many of these units have been sent to you. Thank you for any help.
