This sounds like the solution, albeit it doesn't necessarily need to be crypto. I'm not sure the rules around it, but letting users "buy" your platform money to then "spend" either at once or recurring on creators who then cash it out makes it so there are only two outside visible exchanges (money coming in to you, and money going out to creators).
