So with the events in these brackets, a problem formulation was created regarding how to study recording analysis and fintech as well as opportunities in sharia business in Indonesia. This research is a study of the literature in analytical descriptive type. Discusses e-commerce and Fintech from various reference sources which are collected and used as descriptions to facilitate the analysis process. The results conclude that the transformation of e-commerce and Fintech and its overall application are very beneficial for both consumers and producers, but there are still shortcomings such as fraud, protection of consumers' personal data, and unsuitable ordered goods.
