Maybe you could help us understand "shoppable" can you give a clear description of what that means.
What would this look like for example a small online retailer that today uses wordpress woocommerce / paypal to sell artwork. How do you see them selling through evolution.
By selling their products directly on the Evolution platform to users of Evolution which would mean Evolution will need to have a shopping cart feature of it's own.
For example, If I were a merchant (say a Converse) and I wanted to sell on Evolution I would connect my platform (in this case Woocommerce) to Dash Evolution via the API or DAPI and push my product data into the DE via JSON which will include product information (Sku, price, qty etc).
Now a user should be able to search for a merchant then browse their products in the same way we do on an Amazon and purchase using DASH since that is the Platform currency.
Order informaiton will then be sent back to the merchant platform in order for it to be fulfilled i.e packed and shipped to the customer.
That's how traditional ecommerce marketplaces work with current payment methods.
