+```
+
+## Deployment Steps
+
+### 1. Prerequisites
+
+- Proxmox VE host with LXC support
+- DBIS Core containers already deployed (see [DEPLOYMENT_PLAN.md](../../../../DEPLOYMENT_PLAN.md))
+- PostgreSQL database running (VMID 10100)
+- ChainID 138 RPC nodes accessible (VMID 2500-2502)
+
+### 2. Install Dependencies
+
+SSH into the API container and install Node.js dependencies:
+
+```bash
+# SSH to Proxmox host
+ssh root@192.168.11.10
+
+# Enter API container
+pct enter 10150
+
+# Navigate to project
+cd /opt/dbis-core
+
+# Install dependencies (if not already done)
+pnpm install
+
+# Build the project
+pnpm build
+```
+
+### 3. Configure Environment
+
+Set environment variables in the container:
+
+```bash
+# In container 10150
+nano /opt/dbis-core/.env
+```
+
+Required variables:
+```bash
+# Database
+DATABASE_URL="postgresql://user:pass@192.168.11.100:5432/dbis_core"
+
+# ChainID 138 RPC (admin/deployment: RPC_CORE_1)
+CHAIN_138_RPC_URL="http://192.168.11.211:8545"
+CHAIN_138_RPC_URL_BACKUP="http://192.168.11.251:8545"
+
+# Risk Parameters (optional, defaults in config.ts)
+MAX_LTV=0.30
+MAX_USDTZ_EXPOSURE=0.25
+USDTZ_DISCOUNT_RATE=0.40
+
+# Logging
+LOG_LEVEL="info"
+```
+
+### 4. Run as Service
+
+Create a systemd service for the arbitrage orchestrator:
+
+```bash
+# In container 10150
+cat > /etc/systemd/system/dbis-arbitrage.service << 'EOF'
+[Unit]
+Description=DBIS Deal Orchestration Service
+After=network.target postgresql.service
+
+[Service]
+Type=simple
+User=dbis
+WorkingDirectory=/opt/dbis-core
+Environment=NODE_ENV=production
+ExecStart=/usr/bin/node dist/src/core/defi/arbitrage/cli.js execute \
+  --totalEthValue 10000000 \
+  --participantBankId BANK001 \
+  --moduleId MODULE001
+Restart=always
+RestartSec=10
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+# Enable and start
+systemctl enable dbis-arbitrage
+systemctl start dbis-arbitrage
+```
+
+### 5. Integration with API Server
+
+The arbitrage service can also be called via the DBIS Core API:
+
+```typescript
+// In your API route handler
+import { dealOrchestratorService } from '@/core/defi/arbitrage';
+
+app.post('/api/deals/execute', async (req, res) => {
+  const result = await dealOrchestratorService.executeDeal({
+    totalEthValue: req.body.totalEthValue,
+    participantBankId: req.body.participantBankId,
+    moduleId: req.body.moduleId,
+  });
+  
+  res.json(result);
+});
+```
+
+## Network Configuration
+
+### Internal Network (Container-to-Container)
+
+- **Database**: `192.168.11.100:5432` (PostgreSQL)
+- **Redis**: `192.168.11.125:6379` (Cache, VMID 10120)
+- **RPC Nodes**: `192.168.11.250-252:8545` (ChainID 138)
+
+### External Network (Blockchain)
+
+- **ChainID 138**: Public blockchain network
+- **Smart Contracts**: Deployed on ChainID 138
+- **RPC Endpoints**: Accessible via internal RPC nodes
+
+## Monitoring
+
+### Logs
+
+```bash
+# View service logs
+journalctl -u dbis-arbitrage -f
+
+# View application logs
+tail -f /opt/dbis-core/logs/arbitrage.log
+```
+
+### Health Checks
+
+The service exposes health endpoints (if integrated with API):
+
+```bash
+# Check service status
+curl http://192.168.11.150:3000/api/health/arbitrage
+
+# Check deal status
+curl http://192.168.11.150:3000/api/deals/{dealId}/status
+```
+
+## High Availability
+
+### Primary/Secondary Setup
+
+- **Primary (10150)**: Active arbitrage execution
+- **Secondary (10151)**: Standby for failover
+- **Load Balancer**: Routes requests between containers
+
+### Failover
+
+If primary container fails:
+1. Load balancer detects failure
+2. Routes traffic to secondary (10151)
+3. Secondary takes over deal execution
+4. Database state is shared (PostgreSQL replication)
+
+## Security Considerations
+
+### Container Isolation
+
+- **Unprivileged containers**: Reduced security risk
+- **Network isolation**: Containers on private bridge
+- **Resource limits**: CPU and memory caps enforced
+
+### Key Management
+
+- **Private keys**: Stored in secure key management service
+- **API credentials**: Environment variables (not in code)
+- **Database credentials**: Rotated regularly
+
+## Troubleshooting
+
+### Container Access
+
+```bash
+# SSH to Proxmox host
+ssh root@192.168.11.10
+
+# Enter container
+pct enter 10150
+
+# Check service status
+systemctl status dbis-arbitrage
+
+# View logs
+journalctl -u dbis-arbitrage -n 100
+```
+
+### Common Issues
+
+1. **Database Connection Failed**
+   - Verify PostgreSQL container (10100) is running
+   - Check network connectivity: `ping 192.168.11.100`
+   - Verify DATABASE_URL in .env
+
+2. **RPC Connection Failed**
+   - Verify RPC nodes (2500-2502) are running
+   - Check RPC endpoint URLs
+   - Test: `curl http://192.168.11.250:8545`
+
+3. **Service Won't Start**
+   - Check logs: `journalctl -u dbis-arbitrage`
+   - Verify dependencies: `pnpm install`
+   - Check file permissions

+
+---
+
+## Security Enhancements
+
+### 1. Private Key Management
+
+**Current State**: Private keys are not explicitly handled in the current implementation.
+
+**Recommendations**:
+- **Use Hardware Security Module (HSM)** for key storage
+- **Implement key rotation** policies
+- **Separate keys per deal** to limit blast radius
+- **Never log private keys** or sensitive data
+- **Use environment variables** for sensitive configuration
+- **Implement key derivation** from master seed (BIP32/BIP44)
+
+**Implementation**:
+```typescript
+// Add to config.ts
+export const KEY_MANAGEMENT = {
+  HSM_ENABLED: process.env.HSM_ENABLED === 'true',
+  HSM_PROVIDER: process.env.HSM_PROVIDER || 'vault',
+  KEY_ROTATION_INTERVAL_DAYS: 90,
+  MAX_KEYS_PER_DEAL: 1,
+};
+```
+
+### 2. Transaction Signing Security
+
+**Recommendations**:
+- **Multi-signature wallets** for large deals (>$1M)
+- **Time-locked transactions** for critical operations
+- **Transaction simulation** before execution
+- **Gas price limits** to prevent MEV attacks
+- **Nonce management** to prevent replay attacks
+
+### 3. Access Control & Authorization
+
+**Recommendations**:
+- **Role-based access control (RBAC)** for deal execution
+- **Deal approval workflows** for large amounts
+- **Audit logging** for all deal operations
+- **IP whitelisting** for API access
+- **Rate limiting** to prevent abuse
+
+**Implementation**:
+```typescript
+// Add authorization middleware
+export interface DealAuthorization {
+  userId: string;
+  roles: string[];
+  maxDealSize: Decimal;
+  requiresApproval: boolean;
+}
+
+export function authorizeDeal(
+  auth: DealAuthorization,
+  request: DealExecutionRequest
+): boolean {
+  if (request.totalEthValue.gt(auth.maxDealSize)) {
+    return false;
+  }
+  if (request.totalEthValue.gt(new Decimal('5000000')) && !auth.roles.includes('senior_trader')) {
+    return false;
+  }
+  return true;
+}
+```
+
+### 4. Input Validation & Sanitization
+
+**Recommendations**:
+- **Strict input validation** for all parameters
+- **Decimal precision limits** to prevent overflow
+- **Address format validation** for blockchain addresses
+- **Sanitize all user inputs** before processing
+- **Reject suspicious patterns** (e.g., negative values, extreme sizes)
+
+---
+
+## Performance Optimizations
+
+### 1. Caching Strategy
+
+**Recommendations**:
+- **Cache RPC responses** (token prices, exchange rates)
+- **Cache risk calculations** for repeated requests
+- **Use Redis** for distributed caching
+- **Implement cache invalidation** strategies
+- **Cache TTL** based on data volatility
+
+**Implementation**:
+```typescript
+// Add caching service
+import { Redis } from 'ioredis';
+
+export class ArbitrageCacheService {
+  private redis: Redis;
+  private readonly TTL = {
+    PRICE_DATA: 60, // 1 minute
+    RISK_CALC: 300, // 5 minutes
+    EXCHANGE_RATE: 30, // 30 seconds
+  };
+
+  async getCachedPrice(tokenAddress: string): Promise<Decimal | null> {
+    const cached = await this.redis.get(`price:${tokenAddress}`);
+    return cached ? new Decimal(cached) : null;
+  }
+
+  async setCachedPrice(tokenAddress: string, price: Decimal): Promise<void> {
+    await this.redis.setex(
+      `price:${tokenAddress}`,
+      this.TTL.PRICE_DATA,
+      price.toString()
+    );
+  }
+}
+```
+
+### 2. Parallel Execution
+
+**Recommendations**:
+- **Parallel RPC calls** where possible
+- **Batch transaction submissions** when safe
+- **Async step execution** for independent operations
+- **Connection pooling** for database and RPC connections
+
+**Implementation**:
+```typescript
+// Parallel execution example
+async executeStep1Parallel(request: DealExecutionRequest): Promise<Step1Result> {
+  const [wethBalance, collateralBalance, borrowRate] = await Promise.all([
+    this.getWethBalance(request.workingLiquidityEth),
+    this.getCollateralBalance(),
+    this.getBorrowRate(),
+  ]);
+  
+  // Process results...
+}
+```
+
+### 3. Database Query Optimization
+
+**Recommendations**:
+- **Index critical columns** (dealId, status, timestamp)
+- **Use connection pooling** (Prisma already does this)
+- **Batch database writes** where possible
+- **Optimize Prisma queries** (select only needed fields)
+- **Use database transactions** for atomic operations
+
+**Implementation**:
+```typescript
+// Add database indexes
+// In Prisma schema:
+model Deal {
+  id        String   @id @default(uuid())
+  status   DealStatus
+  createdAt DateTime @default(now())
+  
+  @@index([status, createdAt])
+  @@index([participantBankId, status])
+}
+```
+
+### 4. RPC Connection Management
+
+**Recommendations**:
+- **Connection pooling** for RPC clients
+- **Failover to backup RPC nodes** automatically
+- **Health checks** for RPC endpoints
+- **Request batching** where supported
+- **Timeout configuration** per operation type
+
+---
+
+## Monitoring & Observability
+
+### 1. Metrics Collection
+
+**Recommendations**:
+- **Prometheus metrics** for all operations
+- **Custom business metrics** (deals executed, profit captured, failures)
+- **Performance metrics** (execution time, gas costs)
+- **Risk metrics** (LTV ratios, exposure levels)
+
+**Implementation**:
+```typescript
+import { Counter, Histogram, Gauge } from 'prom-client';
+
+export const metrics = {
+  dealsExecuted: new Counter({
+    name: 'arbitrage_deals_executed_total',
+    help: 'Total number of deals executed',
+    labelNames: ['status', 'participant_bank'],
+  }),
+  
+  dealDuration: new Histogram({
+    name: 'arbitrage_deal_duration_seconds',
+    help: 'Time to execute a deal',
+    buckets: [1, 5, 10, 30, 60, 120],
+  }),
+  
+  currentLtv: new Gauge({
+    name: 'arbitrage_current_ltv_ratio',
+    help: 'Current LTV ratio across all active deals',
+  }),
+  
+  profitCaptured: new Counter({
+    name: 'arbitrage_profit_captured_total',
+    help: 'Total profit captured in USD',
+  }),
+};
+```
+
+### 2. Structured Logging
+
+**Recommendations**:
+- **Structured JSON logging** (Winston already configured)
+- **Log levels** appropriate to severity
+- **Correlation IDs** for request tracing
+- **Sensitive data masking** in logs
+- **Log aggregation** (ELK stack, Loki)
+
+**Implementation**:
+```typescript
+// Enhanced logging
+export class DealLogger {
+  private logger: winston.Logger;
+  
+  logDealStart(dealId: string, request: DealExecutionRequest): void {
+    this.logger.info('Deal execution started', {
+      dealId,
+      totalEthValue: request.totalEthValue.toString(),
+      participantBankId: request.participantBankId,
+      timestamp: new Date().toISOString(),
+    });
+  }
+  
+  logDealStep(dealId: string, step: DealStep, result: any): void {
+    this.logger.info('Deal step completed', {
+      dealId,
+      step,
+      status: result.status,
+      transactionHash: result.transactionHash,
+      duration: result.duration,
+    });
+  }
+  
+  logRiskViolation(dealId: string, violation: string): void {
+    this.logger.error('Risk violation detected', {
+      dealId,
+      violation,
+      severity: 'HIGH',
+    });
+  }
+}
+```
+
+### 3. Alerting
+
+**Recommendations**:
+- **Alert on risk violations** (LTV > 30%, exposure > 25%)
+- **Alert on deal failures** (failed steps, frozen deals)
+- **Alert on system errors** (RPC failures, database errors)
+- **Alert on performance degradation** (slow execution, high gas)
+- **Alert on unusual patterns** (too many deals, large sizes)
+
+**Implementation**:
+```typescript
+// Alert service
+export class AlertService {
+  async sendAlert(alert: Alert): Promise<void> {
+    // Send to PagerDuty, Slack, email, etc.
+    if (alert.severity === 'CRITICAL') {
+      await this.sendPagerDutyAlert(alert);
+    }
+    await this.sendSlackNotification(alert);
+  }
+  
+  async checkRiskThresholds(deal: DealState): Promise<void> {
+    if (deal.currentLtv.gt(new Decimal('0.30'))) {
+      await this.sendAlert({
+        severity: 'CRITICAL',
+        message: `LTV exceeded 30%: ${deal.currentLtv.toString()}`,
+        dealId: deal.dealId,
+      });
+    }
+  }
+}
+```
+
+### 4. Distributed Tracing
+
+**Recommendations**:
+- **OpenTelemetry integration** for request tracing
+- **Trace deal execution** across all steps
+- **Trace RPC calls** and database queries
+- **Correlate logs** with traces
+
+---
+
+## Testing Strategy
+
+### 1. Unit Tests
+
+**Recommendations**:
+- **Test all services** independently
+- **Mock external dependencies** (RPC, database)
+- **Test edge cases** (zero values, extreme values)
+- **Test error handling** paths
+- **Aim for >80% code coverage**
+
+**Implementation**:
+```typescript
+// Example unit test
+describe('RiskControlService', () => {
+  it('should reject deals with LTV > 30%', () => {
+    const request = {
+      totalEthValue: new Decimal('10000000'),
+      maxLtv: new Decimal('0.35'), // Exceeds limit
+    };
+    
+    const result = riskControlService.validateDealRequest(request);
+    expect(result.isValid).toBe(false);
+    expect(result.errors).toContain('LTV exceeds maximum of 30%');
+  });
+});
+```
+
+### 2. Integration Tests
+
+**Recommendations**:
+- **Test full deal execution** with mock blockchain
+- **Test database interactions** with test database
+- **Test error recovery** scenarios
+- **Test state transitions** between steps
+
+### 3. End-to-End Tests
+
+**Recommendations**:
+- **Test complete arbitrage loop** on testnet
+- **Test failure scenarios** (redemption freeze, RPC failure)
+- **Test with real RPC nodes** (testnet only)
+- **Performance testing** under load
+
+### 4. Property-Based Testing
+
+**Recommendations**:
+- **Test with random valid inputs** (fast-check)
+- **Verify invariants** always hold
+- **Test risk limits** with various inputs
+- **Test mathematical correctness** of calculations
+
+---
+
+## Error Handling & Resilience
+
+### 1. Retry Logic
+
+**Recommendations**:
+- **Exponential backoff** for transient failures
+- **Retry RPC calls** with limits
+- **Retry database operations** for connection errors
+- **Circuit breaker pattern** for failing services
+
+**Implementation**:
+```typescript
+// Retry utility
+export async function retryWithBackoff<T>(
+  fn: () => Promise<T>,
+  maxRetries: number = 3,
+  initialDelay: number = 1000
+): Promise<T> {
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      return await fn();
+    } catch (error) {
+      if (i === maxRetries - 1) throw error;
+      await sleep(initialDelay * Math.pow(2, i));
+    }
+  }
+  throw new Error('Max retries exceeded');
+}
+```
+
+### 2. Graceful Degradation
+
+**Recommendations**:
+- **Continue operation** when non-critical services fail
+- **Queue failed operations** for retry
+- **Fallback to backup RPC nodes**
+- **Maintain read-only mode** during outages
+
+### 3. Transaction Safety
+
+**Recommendations**:
+- **Verify transaction success** before proceeding
+- **Handle transaction reverts** gracefully
+- **Track transaction status** until confirmed
+- **Implement transaction timeouts**
+
+### 4. State Recovery
+
+**Recommendations**:
+- **Periodic state snapshots** for recovery
+- **Resume from last successful step** on restart
+- **Idempotent operations** where possible
+- **State validation** on recovery
+
+---
+
+## Database & State Management
+
+### 1. Prisma Schema Enhancements
+
+**Recommendations**:
+- **Add Deal model** to Prisma schema
+- **Add indexes** for performance
+- **Add relationships** (Deal → Steps, Deal → Transactions)
+- **Add audit fields** (createdAt, updatedAt, version)
+
+**Implementation**:
+```prisma
+model Deal {
+  id                String   @id @default(uuid())
+  dealId            String   @unique
+  status            DealStatus
+  participantBankId String
+  moduleId          String
+  totalEthValue     Decimal  @db.Decimal(20, 8)
+  currentLtv        Decimal  @db.Decimal(5, 4)
+  usdtzExposure     Decimal  @db.Decimal(20, 8)
+  profit            Decimal? @db.Decimal(20, 8)
+  createdAt         DateTime @default(now())
+  updatedAt         DateTime @updatedAt
+  version           Int      @default(1)
+  
+  steps    DealStep[]
+  transactions Transaction[]
+  
+  @@index([status, createdAt])
+  @@index([participantBankId])
+}
+
+model DealStep {
+  id          String   @id @default(uuid())
+  dealId      String
+  step        Int
+  status      String
+  result      Json?
+  error       String?
+  executedAt  DateTime @default(now())
+  
+  deal Deal @relation(fields: [dealId], references: [id])
+  
+  @@index([dealId, step])
+}
+```
+
+### 2. State Persistence
+
+**Recommendations**:
+- **Persist deal state** after each step
+- **Use database transactions** for atomic updates
+- **Implement optimistic locking** (version field)
+- **Backup state** periodically
+
+### 3. Data Retention
+
+**Recommendations**:
+- **Archive completed deals** after 90 days
+- **Retain failed deals** for analysis (1 year)
+- **Compress old data** for storage efficiency
+- **Compliance with data retention** policies
+
+---
+
+## On-Chain Integration
+
+### 1. Smart Contract Interaction
+
+**Recommendations**:
+- **Use ethers.js or viem** for contract calls
+- **Implement contract ABIs** for all protocols
+- **Gas estimation** before transactions
+- **Transaction simulation** (eth_call) before execution
+
+**Implementation**:
+```typescript
+// Contract interaction service
+export class ContractService {
+  private provider: ethers.Provider;
+  private signer: ethers.Signer;
+  
+  async wrapEth(amount: Decimal): Promise<string> {
+    const wethContract = new ethers.Contract(
+      CHAIN138_TOKENS.WETH,
+      WETH_ABI,
+      this.signer
+    );
+    
+    // Simulate first
+    await this.simulateTransaction(() => 
+      wethContract.deposit({ value: parseEther(amount.toString()) })
+    );
+    
+    // Execute
+    const tx = await wethContract.deposit({ 
+      value: parseEther(amount.toString()) 
+    });
+    return tx.hash;
+  }
+  
+  private async simulateTransaction(
+    fn: () => Promise<any>
+  ): Promise<void> {
+    // Use eth_call to simulate
+    // Throw if simulation fails
+  }
+}
+```
+
+### 2. Transaction Management
+
+**Recommendations**:
+- **Nonce management** to prevent conflicts
+- **Gas price optimization** (EIP-1559)
+- **Transaction queuing** for ordered execution
+- **Transaction monitoring** until confirmed
+
+### 3. Event Listening
+
+**Recommendations**:
+- **Listen to on-chain events** (transfers, approvals)
+- **Update state** based on events
+- **Handle event delays** and reorgs
+- **Event replay** for missed events
+
+### 4. Multi-Chain Support (Future)
+
+**Recommendations**:
+- **Abstract chain-specific logic** into adapters
+- **Support multiple chains** (ChainID 138, 651940, etc.)
+- **Cross-chain state** synchronization
+- **Chain-specific configurations**
+
+---
+
+## Risk Management Enhancements
+
+### 1. Real-Time Risk Monitoring
+
+**Recommendations**:
+- **Continuous LTV monitoring** across all deals
+- **Real-time exposure calculations**
+- **Automated risk alerts** when thresholds approached
+- **Risk dashboard** for visualization
+
+**Implementation**:
+```typescript
+// Real-time risk monitor
+export class RiskMonitor {
+  private interval: NodeJS.Timeout;
+  
+  start(): void {
+    this.interval = setInterval(async () => {
+      const activeDeals = await this.getActiveDeals();
+      for (const deal of activeDeals) {

+    }
+  }
+}
+```
+
+### 2. Dynamic Risk Limits
+
+**Recommendations**:
+- **Adjust limits** based on market conditions
+- **Reduce limits** during high volatility
+- **Increase limits** when conditions are stable
+- **Market-based risk scoring**
+
+### 3. Stress Testing
+
+**Recommendations**:
+- **Simulate extreme scenarios** (ETH -50%, redemption freeze)
+- **Calculate impact** on all active deals
+- **Test recovery procedures**
+- **Regular stress tests** (monthly)
+
+### 4. Risk Reporting
+
+**Recommendations**:
+- **Daily risk reports** for management
+- **Exposure breakdowns** by asset type
+- **Historical risk metrics**
+- **Compliance reporting**
+
+---
+
+## Operational Best Practices
+
+### 1. Deployment Strategy
+
+**Recommendations**:
+- **Blue-green deployment** for zero downtime
+- **Canary releases** for gradual rollout
+- **Feature flags** for new functionality
+- **Rollback procedures** documented
+
+### 2. Configuration Management
+
+**Recommendations**:
+- **Environment-specific configs** (dev, staging, prod)
+- **Secrets management** (Vault, AWS Secrets Manager)
+- **Config validation** on startup
+- **Hot reload** for non-critical configs
+
+### 3. Backup & Recovery
+
+**Recommendations**:
+- **Daily database backups**
+- **State snapshots** before major operations
+- **Test recovery procedures** regularly
+- **Disaster recovery plan** documented
+
+### 4. Capacity Planning
+
+**Recommendations**:
+- **Monitor resource usage** (CPU, memory, disk)
+- **Scale horizontally** when needed
+- **Load testing** before production
+- **Resource limits** per container
+
+---
+
+## Documentation Improvements
+
+### 1. API Documentation
+
+**Recommendations**:
+- **OpenAPI/Swagger** specification
+- **Code examples** for all endpoints
+- **Error response** documentation
+- **Rate limiting** documentation
+
+### 2. Runbooks
+
+**Recommendations**:
+- **Operational runbooks** for common tasks
+- **Troubleshooting guides** for errors
+- **Incident response** procedures
+- **Recovery procedures** for failures
+
+### 3. Architecture Diagrams
+
+**Recommendations**:
+- **System architecture** diagrams
+- **Data flow** diagrams
+- **Deployment** diagrams
+- **Sequence diagrams** for deal execution
+
+### 4. Developer Onboarding
+
+**Recommendations**:
+- **Setup guide** for new developers
+- **Development workflow** documentation
+- **Code style guide**
+- **Testing guide**
+
+---
+
+## Code Quality & Architecture
+
+### 1. Type Safety
+
+**Recommendations**:
+- **Strict TypeScript** configuration
+- **No `any` types** (use `unknown` if needed)
+- **Type guards** for runtime validation
+- **Branded types** for IDs and addresses
+
+**Implementation**:
+```typescript
+// Branded types
+type DealId = string & { readonly __brand: 'DealId' };
+type TokenAddress = string & { readonly __brand: 'TokenAddress' };
+
+function createDealId(id: string): DealId {
+  if (!isValidUuid(id)) throw new Error('Invalid deal ID');
+  return id as DealId;
+}
+```
+
+### 2. Dependency Injection
+
+**Recommendations**:
+- **Dependency injection** for testability
+- **Interface-based design** for flexibility
+- **Service locator pattern** for shared services
+- **Factory pattern** for complex objects
+
+### 3. Code Organization
+
+**Recommendations**:
+- **Feature-based structure** (not layer-based)
+- **Shared utilities** in common module
+- **Domain models** separate from services
+- **Clear separation** of concerns
+
+### 4. Code Reviews
+
+**Recommendations**:
+- **Mandatory code reviews** before merge
+- **Automated checks** (linting, tests)
+- **Security review** for sensitive changes
+- **Documentation** for complex logic
+
+---
+
+## Deployment & DevOps
+
+### 1. CI/CD Pipeline
+
+**Recommendations**:
+- **Automated testing** on every commit
+- **Automated builds** and deployments
+- **Staging environment** for testing
+- **Production deployments** with approval
+
+**Implementation**:
+```yaml
+# .github/workflows/deploy.yml
+name: Deploy Arbitrage Service
+on:
+  push:
+    branches: [main]
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - run: pnpm install
+      - run: pnpm test
+      - run: pnpm lint
+  
+  deploy:
+    needs: test
+    runs-on: ubuntu-latest
+    steps:
+      - name: Deploy to Proxmox
+        run: ./scripts/deploy-to-proxmox.sh
+```
+
+### 2. Infrastructure as Code
+
+**Recommendations**:
+- **Terraform/Ansible** for infrastructure
+- **Version control** for infrastructure changes
+- **Automated provisioning** of containers
+- **Configuration drift** detection
+
+### 3. Health Checks
+
+**Recommendations**:
+- **Health check endpoint** (/health)
+- **Readiness probe** for dependencies
+- **Liveness probe** for service status
+- **Startup probe** for slow-starting services
+
+**Implementation**:
+```typescript
+// Health check endpoint
+app.get('/health', async (req, res) => {
+  const health = {
+    status: 'healthy',
+    timestamp: new Date().toISOString(),
+    checks: {
+      database: await checkDatabase(),
+      rpc: await checkRpc(),
+      redis: await checkRedis(),
+    },
+  };
+  
+  const allHealthy = Object.values(health.checks).every(c => c === 'ok');
+  res.status(allHealthy ? 200 : 503).json(health);
+});
+```
+
+### 4. Logging & Debugging
+
+**Recommendations**:
+- **Structured logging** (already implemented)
+- **Log levels** appropriate to environment
+- **Debug mode** for development
+- **Log aggregation** and search
+
+---
+
