Chainlink Hackathon Entry - Amazon Bedrock AI integration for sustainable, cross-chain e-commerce
✅ AI Shopping Assistant - Personalized product recommendations ✅ Pricing Optimizer - Dynamic pricing strategies for sellers ✅ Dispute Resolution - Automated AI analysis and resolution ✅ Smart Contract Integration - Chainlink Functions + AWS Bedrock ✅ Production Ready - Full UI, API routes, and documentation
Current e-commerce platforms suffer from three critical issues:
- Generic AI recommendations based solely on purchase history, ignoring user values (sustainability, ethics, budget)
- Trust gaps with fake reviews, opaque pricing, and centralized dispute resolution
- Cross-chain fragmentation limiting liquidity and user choice across different blockchain networks
A decentralized marketplace that combines ethical AI-driven recommendations with trustless smart contract escrow, enabling seamless cross-chain commerce.
