What it does
Red Button is a cyber-safe fintech panic system designed to protect users and businesses during financial emergencies. When a suspicious transaction or security breach occurs, users can instantly:
Freeze all linked accounts with a single press.
Trigger emergency fund release for urgent needs.
Flag suspicious activity using built-in AI fraud detection.
Log events immutably using blockchain-style security.
Notify emergency contacts or security teams automatically.
It’s a lifeline for financial safety — protecting users in real time while empowering banks and fintechs to act faster.
How we built it
Frontend: React Native (Expo) – mobile interface with a big panic button UI.
Backend: Node.js + Express (simulated banking APIs: /freezeAccount, /getTransactions).
IoT Hardware: ESP32 microcontroller with a push button connected via WiFi (panic signal).
AI Fraud Detection: Python + scikit-learn anomaly detection on mock transactions.
Cybersecurity Layer: JWT authentication, HTTPS encryption, and blockchain-style event logs using a local ledger.
Cloud Deployment: Hosted backend on mock cloud server (Dockerized Node.js environment).
Challenges we ran into
Integrating the IoT button with the backend securely over WiFi.
Simulating realistic fintech APIs without access to actual bank systems.
Managing encryption and API authentication between multiple services.
Building an AI model that feels intelligent within the short hackathon timeframe.
Designing a clean, panic-mode UI that works instantly with minimal latency.
Accomplishments that we're proud of
Successfully linked the IoT panic button to trigger live API calls.
Built a secure backend using encryption and role-based access.
Designed a working AI fraud alert system with mock data.
Implemented blockchain-style logging to ensure traceability.
Created a fully functional demo flow for judges to experience a real-world financial emergency scenario.
What we learned
How to integrate IoT hardware with fintech APIs.
Building secure fintech systems using the NIST & OWASP frameworks.
Importance of user-centric UX under high-stress situations.
Balancing innovation, security, and speed during a hackathon.
Effective team collaboration across backend, AI, and cybersecurity roles.
What's next for Red button
Integrate real APIs (e.g., Stitch API / Plaid) for authentic banking simulation.
Expand AI detection using transaction pattern learning and geolocation data.
Develop a Red Button Smartwatch App for quicker panic access.
Partner with banks, fintechs, and cybersecurity firms to pilot real use cases.
Launch a “Red Business Suite” for enterprises to protect employees and corporate accounts.
