First, which route is this?
This module covers the route RealOpen runs: the buyer converts at closing, either for an all-cash purchase or for the down payment on a financed one. Start by asking how the buyer plans to use the crypto, as in Module 2.
If they have already sold, or they are borrowing against it, the conversion steps below do not apply, and you run the deal the way you would for any cash or financed buyer. A financed buyer can still use RealOpen for verification alone, to document holdings for the lender.
