What it does
ClaimChain is a universal ownership and claims platform that creates a trusted digital identity for every product or service throughout its lifecycle.
Manufacturers, retailers, insurers, and consumers share a single source of truth for product ownership, warranty coverage, authenticity, and claims history.
Core Capabilities
Digital Ownership & Warranty Transfer
Ownership can be transferred digitally when a product is sold, gifted, or resold. The new owner instantly inherits verified warranty coverage, while the complete provenance and ownership history remain preserved.
Secondary Market Authentication
ClaimChain enables trusted resale by verifying product authenticity, ownership history, warranty eligibility, and chain of custody. Buyers gain confidence that products are genuine and eligible for support before completing a purchase.
Insurance & Claims Validation
Insurers can verify ownership, purchase history, warranty status, and claim records in real time, reducing fraud and accelerating claims processing.
Recall Management
When a manufacturer issues a recall, ClaimChain instantly:
- Identifies affected owners
- Sends targeted notifications
- Tracks acknowledgement and compliance
- Manages replacement and reimbursement claims
- Provides manufacturers with real-time recall visibility
Counterfeit Prevention
Every registered product maintains a verifiable ownership and authenticity record, helping manufacturers detect counterfeit goods and protect consumers from fraudulent products.
Fraud Intelligence
ClaimChain continuously analyzes ownership, warranty, and claims activity to identify suspicious behavior, including:
- Repeated claims originating from the same device or network
- Unusual geographic claim patterns
- Duplicate serial number submissions
- Ownership transfers that violate expected timelines or behaviors
- Suspicious retailer activity and registration anomalies
- Coordinated fraud rings operating across multiple products or brands
Vision
ClaimChain transforms warranties from static documents into a dynamic ownership network.
Creates a persistent digital identity for each product (or service) to support ownership verification, warranty coverage, recall management, insurance validation, fraud prevention, and trusted resale throughout its entire lifecycle.
How we built it
We built ClaimChain using Next.js 14 for the frontend with Tailwind CSS and Radix UI components, and a Node.js/Express backend with PostgreSQL (Aurora Serverless v2) and DynamoDB for hybrid data storage. Real-time updates use Server-Sent Events, fraud detection uses a rule-based engine, and infrastructure is managed with Pulumi on AWS with Vercel for frontend deployment.
Challenges we ran into
Synchronizing warranty data between PostgreSQL and DynamoDB across regions was complex. Designing a fraud detection engine that balances accuracy with low latency required extensive tuning. Implementing secure ownership transfers with verification codes while preventing race conditions demanded distributed locking. Managing SSE connections at scale and handling webhook idempotency for Stripe payments were also significant challenges.
Accomplishments that we're proud of
We built a complete production-ready warranty management platform with dual-database architecture, real-time fraud detection scoring claims in under 500ms, and a self-service warranty transfer system with multi-factor verification. Our Pulumi infrastructure enables one-click deployments across environments, and the modular service architecture supports both customer and manufacturer portals with role-based access control.
What we learned
We learned the importance of event-driven architecture for complex workflows, the trade-offs between SQL and NoSQL for different data patterns, and how to design distributed systems with eventual consistency. We also gained deep experience with AWS services (EventBridge, SQS, S3, SES), implementing circuit breakers and retry logic, and building secure authentication with JWT and API keys.
What's next for ClaimChain
We plan to add ML-powered fraud detection using historical claim patterns, expand to multi-tenant support with data isolation, integrate with more retailer POS systems for automatic warranty registration, build a mobile app with QR scanning, add blockchain-based verification for tamper-proof warranty records, and develop an analytics dashboard with predictive insights for manufacturers.
