Whereas the RXP controls Rezolve’s promotion and marketing features, the Rezolve Commerce Engine (RCE) is the engine that drives all the ecommerce functionality needed for customers to place orders securely with Rezolve.
Merchants can view and update all their inventory and orders directly in Rezolve by using an online dashboard called the Merchant Portal.

If you have connected your online store to Rezolve then you won’t need to go into the Merchant Portal except during the initial setup phase.
If, however, you don’t have an integrated online store and you are managing products and orders directly with Rezolve, then the Merchant Portal is your tool for adding your products and processing your orders.
