Nooo lol slippery slope. Turns into paying her to agree to a date, which would be kinda disgusting. Not too mention payment for other things. Peer to peer payments in general are cool of course. But in the context of a dating app I would explicitly exclude that from the design. Just completely backwards incentives imo. It's already bad enough with some using dating apps purely too boost external social media accounts.

Anyway not that this can be prevented. People will build all sorts of cool and questionable shit. But to me the answer ought to be focus.
