Build a Digital Wallet App

With the rise of digital payments, e-wallet apps have become essential in everyday finance. Creating one gives you hands-on experience with payment gateways, user authentication, secure APIs, transaction logs, and real-time data syncing—ideal for mastering app development in the fintech space.

The app allows users to add funds, send or receive money, link cards or bank accounts, view detailed transaction history, and manage daily limits or notifications. Ensure full encryption and compliance with basic financial data protection standards.

Users sign up, verify identity, and add a preferred payment method. They can then transfer funds to others using wallet balance or linked accounts, track expenses in real-time, and manage all activity via a secure dashboard. KYC and encryption ensure compliance and data safety.
