📋 Setup Requirements (For Team)

What Teammates Need to Do

Option 1: Demo Mode (No Setup)

npm install
npm run dev
# Works with mock data, no configuration needed

Option 2: Full MVP Mode (5 minutes)

  1. Create free Supabase account → Get API keys
  2. Create free Cloudinary account → Get API keys
  3. Copy .env.example to .env.local
  4. Fill in credentials
  5. Run npm run dev

Detailed instructions: See MVP_SETUP_GUIDE.md

  • Onfido (built for identity)

Priority 2: Blockchain Integration (2-3 hours)

Smart Contract:

// Simple credential storage contract
mapping(string => uint256) public credentials; // hash → timestamp

Steps:

  1. Deploy to Polygon Mumbai testnet
  2. Update src/app/api/credentials/route.ts
  3. Store transaction hash in database

Priority 3: Production Hardening (2-3 hours)

  • Add rate limiting (express-rate-limit)
