✅ Backend deployed: Railway
✅ Frontend deployed: Vercel
❌ Yellow Network: NOT CONNECTED
❌ Testnet: NOT ACTIVE
❌ On-chain: NOT YET
Endpoint: wss://clearnet-sandbox.yellow.com/ws
Status: disconnected
Mode: FALLBACK
Why it's not connecting:
- Yellow Network sandbox may require allowlisting
- WebSocket authentication may need specific handshake
- Yellow sandbox endpoint might be restricted to approved apps
- May need to register app on Yellow Network dashboard first
Current Behavior:
- Backend gracefully falls back to simulation mode
- All APIs work with mock responses
- Full flow can be demonstrated
- Audit logging and compliance features fully functional

What's Working:
- ✅ CompliFlow backend (all compliance features)
- ✅ Session governance (expiration, allowance, wallet binding)
- ✅ Policy evaluation
- ✅ Cryptographic receipts
- ✅ Audit trail
- ✅ Order state machine
What's NOT Working:
- ❌ Real Yellow Network connection
- ❌ State channels
- ❌ On-chain settlement
- ❌ Real-time WebSocket updates
- Visit Yellow Network developer portal
- Register application with APP-4720-5FF0
- Get proper credentials/allowlisting
- Configure authentication handshake
During Checkpoint #2 session (8.03.2026):
- Show current implementation
- Ask about sandbox access requirements
- Get testnet credentials
- Request authentication documentation
If sandbox is restricted, may need to go directly to testnet/mainnet:
# Change in yellow_client.py
self.ws_url = "wss://clearnet-testnet.yellow.com/ws" # If available1. Compliance Architecture ✅
- Session governance with expiration and allowance limits
- Policy engine evaluation before execution
- Cryptographic receipt signing (SHA-256 hashing)
- Complete audit trail for institutional compliance
2. Order Lifecycle Management ✅
- State machine with enforced transitions
- Automatic timestamp tracking
- Status progression simulation
3. API Integration Readiness ✅
- WebSocket client implemented (Yellow SDK patterns)
- Fallback mode with graceful degradation
- Complete API documentation
- Production-ready error handling
4. Full Stack Application ✅
- Frontend: Next.js with Yellow Network branding
- Backend: FastAPI with compliance features
- Deployed: Railway + Vercel
- ✅ Session validation
- ✅ Policy evaluation
- ✅ Receipt signing
- ✅ Order submission (fallback)
- ✅ Order status tracking (fallback)
- ✅ Audit logging
- ✅ Health checks
- ✅ Session governance enforcement
- ⏳ WebSocket connection
- ⏳ Real-time state channels
- ⏳ On-chain settlement
- ⏳ Testnet integration
- For Demo: Use current fallback mode to show compliance features
- For Yellow Team: Present implementation and request connection guidance
- For Production: Get testnet access and credentials
- For On-chain: Deploy smart contracts after Yellow connection is active
Testnet Status: ❌ NOT CONNECTED Sandbox Status: ❌ NOT CONNECTED On-chain Status: ❌ NOT YET Fallback Mode: ✅ FULLY FUNCTIONAL
Can Test:
- ✅ All CompliFlow compliance features
- ✅ Complete order flow (simulated Yellow responses)
- ✅ Session governance
- ✅ Audit trail
- ✅ API endpoints
Cannot Test:
- ❌ Real Yellow Network state channels
- ❌ On-chain settlement
- ❌ Real-time WebSocket events
- ❌ Actual blockchain transactions
Ready for: Hackathon demo with full compliance architecture showcase Waiting for: Yellow Network sandbox/testnet access
