A full-stack digital wallet web application designed to emulate the core functionalities of real-world peer-to-peer payment systems. Users can register, log in, view balances, search for other users, and transfer funds — all through an intuitive and responsive interface.
This application simulates a basic digital wallet with user-to-user money transfer functionality. It provides a real-world-like flow including user signup/login, balance management, user discovery, and secure transaction handling.
- Users can sign up and sign in using a secure authentication flow.
- A random dummy balance is assigned to each user upon registration.
- JWT (JSON Web Tokens) are used for secure session handling and route protection.
- After login, users are presented with a personalized dashboard showing their current account balance.
- Access to search and transaction functionalities is available directly from the dashboard.
- Users can search for others by typing the first letter of a username.
- Matching results are fetched in real time from the database.
- Each result includes a “Send Money” button.
- Handles all UI states:
"No Search"(initial state)"User Not Found""Matching Results"
- On clicking “Send Money”, the user is navigated to a transfer page.
- The recipient’s username or ID is passed via the URL.
- Users enter the amount and initiate the transfer.
- Post-transfer:
- Sender's balance is deducted
- Recipient's balance is credited
- All changes are reflected and persisted in the database.
