Diem Reference Merchant Store - Diem

The Diem Reference Merchant project demonstrates the possible integration of Diem payments on an online shopping website. This project is meant to be a reference you can use while building your own merchant solution.

Introduction

You can demo the following concepts using this reference project:

Integration of a Diem payment solution in a pre-existing website without exposing the merchant to Diem Coins or any Diem Blockchain specifics.
Conceptual implementation of a Regulated VASP) service providing such Diem integration to merchants.
Support for Diem payments with web and mobile wallets.

Architecture

The Diem Reference Merchant project demonstrates three main entities that would be separate in most real world scenarios: a merchant, a Regulated VASP, and a liquidity provider.

As illustrated above, this project is a collection of the following interconnected entities:

Online Merchant: This is a demo web shop accepting Diem payments for the items it sells. It is composed of front-end, back-end, and database services.
Regulated Virtual Asset Service Provider (VASP): This entity provides payment clearance, fiat pay-out, and refund services to the merchant. It is composed of back-end and database services.
Liquidity Provider: This service converts (for the Regulated VASP) Diem Coin currencies to and from fiat currencies.
Gateway: This entity manages the network traffic between the outside world and the merchant solution services.
