Fraud-resistant fintech apps aren’t built by luck — they’re engineered.
Modern Android apps must embed security as architecture, not as a patch.
💡 Key ideas:
- Use Clean Architecture + Ports & Adapters for isolation and testability
- Enforce Play Integrity API for device and app verification
- Protect secrets using Android Keystore + AES/GCM
- Enable biometric + device-bound signing for every high-value transaction
- Implement certificate pinning and secure networking
- Integrate feature flags + kill switches to react to fraud events instantly
🔐 Why this matters
Fraud is evolving faster than features. Only a security-first architecture keeps fintech apps compliant, trusted, and scalable in 2025.
