Paytm - Basic Payment App

A full-stack payment application "Paytm" where users can sign in or sign up, transfer money from one account to another, and have their transactions stored securely in MongoDB, adhering to ACID principles. The project is built using ReactJS for the frontend, Express for the backend, and MongoDB for data storage.

Features

• User Authentication:

  • Users can sign up and log in using JWT-based authentication.
  • JWT tokens are generated and verified for secure user sessions.

• Money Transfer:

  • Users can transfer money between accounts.
  • Transactions are recorded in the database securely.

• ACID-compliant Transactions:

  • MongoDB transactions are implemented to ensure atomicity, consistency, isolation, and durability (ACID) during money transfers.
