There may be some creative non-formal solutions though.
On one end of the spectrum you could have a token system and leave it up to the users to figure out actually exchanging money themselves (a lot of poker apps do this).
Getting less hands-on, you could do away with the tokens and just act as a matchmaker, getting two parties who want to make a bet in touch with each other and they could handle it from there.
Getting even less hands-on, you could just function as a place to discuss bets you may want to make in the real world. Eg. sports betting or stock picking (I guess there’s not too many examples of this).
