ZKP Integration with Aadhaar Verification:

Implementing zero-knowledge STARK proofs to verify Aadhaar-linked identity without revealing user data was technically complex and required custom cryptographic circuits.

Cross-Stack Communication:

Ensuring smooth communication between Solidity-based smart contracts and our Next.js frontend introduced challenges in maintaining data consistency and managing async blockchain events.

Performance Bottlenecks in Proof Generation:

Using Rust and SP1 for proof generation required heavy optimization to keep the verification process efficient and scalable.

Protocol Compatibility:

Integrating with DeFi protocols like Aave V3 and Uniswap while preserving user privacy and flash loan security demanded meticulous smart contract design and testing.

Security & Privacy Balance:

Maintaining a strict privacy-first architecture without compromising the functionality or transparency expected in DeFi systems was a constant balancing act.
