Yes, while this is OSS, we haven't yet figured out how to self host an acquiring bank partnership... For now we're using Stripe Connect to set up a merchant account through our Stripe Connect platform. So as long as you are a legal entity (individual or business) in the countries that Stripe does merchant acquiring you should be good to go with us.

Eventually we want to get to a place where we are embedded deeper on the payments side. But for now that's the flow.
