Challenge

• User Authentication and Security: Ensuring secure login/signup and protecting user data.

• Webhook Integration: Handling and validating bank transactions via webhooks.

• Database Management: Managing user data and transaction records efficiently.

• Real-time Updates: Providing real-time updates for transactions and balances.

• P2P Transaction Handling: Ensuring secure and accurate processing of peer-to-peer transactions.

• UI/UX Design: Creating a user-friendly interface and smooth experience.

Solution

To address user authentication and security, implement robust encryption and hashing techniques with NextAuth for secure login and signup. Use session management and secure cookies to protect user data. For webhook integration, set up reliable endpoints with Express and Node.js to handle and validate bank transactions securely. Ensure you properly validate and sanitize incoming data to avoid security vulnerabilities.

In terms of database management, use Prisma to interact with Postgres for efficient data handling, including user and transaction records. Implement proper indexing and optimization techniques to maintain performance as your data grows. For real-time updates, utilize WebSockets or server-sent events to push transaction and balance changes to the user interface instantly.

To handle P2P transactions securely, implement thorough validation and transaction checks to prevent fraud and ensure accuracy. Use strong encryption and secure transaction protocols. Finally, focus on UI/UX design by leveraging TailwindCSS to create a responsive and intuitive interface, ensuring that users have a seamless experience throughout the wallet application.
