Habeel-Shamsudeen/Paytm-Lite

Paytm like application where users can send and receive money using a dummy wallet

Basic Paytm like Web Application

This is a simple Paytm-like payment web application where users can sign up, sign in, search for other users, and transfer money to them from their wallet. The application utilizes a dummy wallet, eliminating the need to input real bank details. Upon signing up, each user is allocated a random amount of money between 200 and 10,000.

Additionally, users have the ability to update their details such as password, first name, and last name. The application implements user authentication using JSON Web Tokens (JWT) for secure access, and input validation is performed using Zod. Passwords are hashed before being stored in the database, ensuring data security.
