Inspiration

"We wanted to bridge India's massively successful UPI payments (6 billion monthly transactions) with crypto's borderless potential. Our struggle to explain wallet addresses to his grandmother - we realized masked UPI IDs could democratize crypto access."

What it does

Banking System Nuances: Reverse-engineered UPI's NPCI specifications through RBI whitepapers Security Protocols: Implemented military-grade encryption for QR-based transactions Regulatory Compliance: Studied SEBI guidelines to ensure legal transaction thresholds

How we built it

Phase 1: Created a Node.js middleware translating UPI requests to blockchain operations Phase 2: Developed custom webhooks mimicking NPCI's response patterns Phase 3: Trained AI model on 50,000+ transaction patterns for fraud detection

Challenges we ran into

Real-Time Reconciliation: Solved through dual-ledger architecture Bank Pushback: Simulated UPI environment after major banks declined API access Gas Fee Optimization: Created dynamic fee calculator using Ethereum mempool data

Accomplishments that we're proud of

development and also provided a strong foundation for tackling future fintech challenges.

What we learned

demonstrate how focused problem-solving and deep platform understanding can create impactful financial solutions, whether bridging traditional banking with web3 or empowering low-cost hardware with crypto capabilities.
