# Tokenization System - Next Steps

## ✅ Completed Implementation

All core components have been implemented:
- Fabric chaincode for tokenized assets and reserves
- Besu ERC-20 contracts
- FireFly orchestration workflows
- Cacti bridge connectors
- SolaceNet capability integration
- Sub-Volume integrations (GAS, GRU, Metaverse)
- Microservices integrations
- Indy identity services
- Deployment scripts and documentation

## 🚀 Deployment Checklist

### 1. Pre-Deployment Setup

- [ ] Review all configuration files
- [ ] Set up environment variables (`.env.tokenization`)
- [ ] Verify network connectivity to all services
- [ ] Set up monitoring infrastructure (Prometheus, Grafana)

### 2. Infrastructure Deployment

- [ ] Deploy Fabric network (if not already deployed)
- [ ] Deploy Besu network (Chain 138)
- [ ] Deploy FireFly instance
- [ ] Deploy Cacti connectors
- [ ] Deploy SolaceNet capability platform
- [ ] Deploy Indy network (optional but recommended)
- [ ] Set up HSM service (for production)

### 3. Contract & Chaincode Deployment

```bash
# Deploy Besu contracts
./scripts/deployment/deploy-tokenization.sh

# Verify deployment
cast code $TOKENIZED_EUR_ADDRESS --rpc-url $CHAIN_138_RPC_URL
cast code $TOKEN_REGISTRY_ADDRESS --rpc-url $CHAIN_138_RPC_URL
```

### 4. Configuration

- [ ] Configure Cacti connectors (Fabric and Besu)
- [ ] Register SolaceNet capabilities
  ```bash
  ./scripts/tokenization/register-solacenet-capabilities.sh
  ```
- [ ] Initialize reserves
  ```bash
  ./scripts/tokenization/initialize-reserves.sh
  ```
- [ ] Set up entitlements in SolaceNet
- [ ] Configure Indy credentials (if using)

### 5. Testing

- [ ] Run unit tests
  ```bash
  forge test --match-path test/tokenization/*
  ```
- [ ] Run integration tests
  ```bash
  npm test -- test/tokenization/
  ```
- [ ] Test end-to-end workflow
  ```bash
  # Mint tokenized asset
  curl -X POST http://localhost:3000/api/v1/solacenet/tokenization/mint \
    -H "Authorization: Bearer $API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "underlyingAsset": "EUR",
      "amount": "1000.00",
      "issuer": "0x...",
      "reserveId": "RESERVE-EUR-001"
    }'
  ```

### 6. Monitoring Setup

- [ ] Deploy Prometheus
- [ ] Configure Grafana dashboards
- [ ] Set up alerting rules
- [ ] Configure log aggregation

### 7. Production Hardening

- [ ] Enable HSM integration
- [ ] Configure multi-attestor quorum
- [ ] Set up backup and recovery
- [ ] Configure disaster recovery procedures
- [ ] Set up audit logging
- [ ] Configure rate limiting
- [ ] Set up API authentication

## 📋 Configuration Files

### Environment Variables

Copy and configure:
```bash
cp .env.tokenization.example .env.tokenization
# Edit .env.tokenization with your values
```

### Configuration Files

- `config/tokenization.config.example.ts` - TypeScript configuration
- `monitoring/prometheus/tokenization-metrics.yml` - Prometheus config
- `monitoring/grafana/tokenization-dashboard.json` - Grafana dashboard

## 🔍 Verification Steps

### 1. Verify Fabric Chaincode

```bash
peer chaincode query \
    -C mychannel \
    -n tokenized-asset \
    -c '{"Args":["GetToken","EUR-T-2025-001"]}'
```

### 2. Verify Besu Contracts

```bash
# Check token balance
cast call $TOKENIZED_EUR_ADDRESS \
    "balanceOf(address)" \
    $USER_ADDRESS \
    --rpc-url $CHAIN_138_RPC_URL

# Check registry
cast call $TOKEN_REGISTRY_ADDRESS \
    "getToken(address)" \
    $TOKENIZED_EUR_ADDRESS \
    --rpc-url $CHAIN_138_RPC_URL
```

### 3. Verify SolaceNet Capabilities

```bash
curl -X GET $SOLACENET_API_URL/api/v1/solacenet/capabilities \
    -H "Authorization: Bearer $SOLACENET_API_KEY"
```

### 4. Verify FireFly Workflows

```bash
curl -X GET $FIREFLY_API_URL/api/v1/namespaces/default/workflows
```

### 5. Verify Cacti Connectors

```bash
curl -X GET $CACTI_API_URL/api/v1/plugins/ledger-connector/fabric/health
curl -X GET $CACTI_API_URL/api/v1/plugins/ledger-connector/besu/health
```

## 🐛 Troubleshooting

### Common Issues

1. **Fabric Chaincode Not Found**
   - Verify chaincode is installed and instantiated
   - Check channel configuration
   - Review peer logs

2. **Besu Contract Not Deployed**
   - Verify deployment transaction succeeded
   - Check contract address in deployment JSON
   - Verify RPC connection

3. **SolaceNet Capability Denied**
   - Check entitlements are configured
   - Verify tenant/program IDs
   - Review policy rules

4. **Cacti Bridge Fails**
   - Verify connectors are healthy
   - Check network connectivity
   - Review connector logs

5. **FireFly Workflow Stuck**
   - Check workflow status
   - Review FireFly logs
   - Verify event subscriptions

## 📊 Monitoring

### Key Metrics to Monitor

- Tokenization operation rate
- Reserve ratio (should be >= 1.0)
- Settlement time (P95, P99)
- Success rate
- Active tokenized assets
- Total supply vs backed amount

### Alerts to Configure

- Reserve ratio < 1.0
- Settlement time > threshold
- Success rate < threshold
- Failed operations > threshold
- Reserve attestation expired
