So (if I’m doing the math right) if the app were to take a 7% cut, a $1 tip would be about 33 cents to Stripe, 7 cents to the app, and 60 cents to the user receiving the tip.
Thanks @pfaffman! Indeed, the post has a better description. I’m looking way of creating a system where users can support other users. A peer-to-peer network between authors. I know Discourse has plugins that enable stripe and paypal donations, but they are focused on donations for the platform itself, not for showing support for other users.
