Hello

By default we have integration for Stripe in Payments App and also we have Stripe Connect App:
1. Payments App doesn't allow site owner to take percentage from sellers. It doesn't matter which payment provider (PayPal, Stripe, ChargeBee, etc) they use. In this case each seller specifies his own details and receives payments directly to his payment account.
2. Stripe Connect allows to connect different Stripe accounts to one Main account. In this case you (as site owner) would be able to take percentage from any transaction (Market, or any other payments related app). You may read about setting up this app here.  Also I recommend you to read more about Stripe Connect technology itself on official site.
