Before I could build this decentralized marketplace, I had to build open-source SaaS that the sellers use. All of that is handled by that platform. The chat simply interfaces with the API just like the built in storefront does.

The marketplace is also built in a way that you can add a Shopify adapter, BigCommerce, custom, etc. It only supports Openfront for now. Even if the store you want to interface with has a custom software, you can write the adapter code and they are added.
