MedChain is a blockchain-powered platform for tracking and authenticating medical supplies from manufacturers to healthcare providers. It ensures transparency, trust, and security in the medical supply chain using role-based dashboards and MetaMask wallet integration.

Blockchain Security: Immutable transaction records for complete transparency.

Product Traceability: Track every product from manufacturing to delivery.

QR Code Verification: Quick and easy product authentication for healthcare providers.

Role-Based Access: Secure login for manufacturers, distributors, and healthcare providers.

MetaMask Integration: All critical actions require MetaMask wallet and on-chain transactions.

Transaction Costs: Each blockchain action (add, assign, sell, verify) incurs a small ETH fee.

Manufacturer Distributor Healthcare Provider Register new medical products View assigned products Scan QR codes to verify authenticity Assign products to distributors Generate QR codes for sales View complete blockchain history Track product lifecycle Update product status Verify product authenticity

Manufacturer adds a new product to the blockchain and assigns it to a distributor.

Distributor receives products, sells them to healthcare providers, and generates QR codes for each sale.

Healthcare Provider scans the QR code to verify the product's authenticity and view its blockchain history.

Frontend: React, TypeScript, Vite, Tailwind CSS, shadcn/ui

Blockchain: Simulated on-chain logic with MetaMask wallet integration

State Management: React Context API

For demo purposes, the following ETH costs are simulated for each blockchain action:

Action Cost (ETH) Add Product 0.001 Assign Product 0.0008 Sell Product 0.0006 Verify Product 0.0002
