🛡️ SECURITY ASSESSMENT

Financial Security (SEVERITY: HIGH)

Private Key Management

Status: ⚠️ NEEDS REVIEW
Files to Audit:

- config/config.yaml

Findings:

• ⚠️ Key management implementation needs security review
• ❌ Missing hardware security module integration
• ❌ No key rotation mechanism implemented

Recommendations:

• Implement HSM-based key management
• Add key rotation capabilities

Risk Factors Identified:

1. No Position Size Limits: Could risk entire capital on single trade
2. Missing Stop-Loss Mechanisms: No automatic loss cutting
3. Insufficient Slippage Protection: Could execute unprofitable trades
4. No Market Impact Analysis: May move markets against position

Risk Mitigation Requirements:

• Implement maximum position size limits (2-5% per trade)
• Add automatic stop-loss at 10% loss threshold
• Implement pre-trade slippage calculations
• Add market depth analysis before execution

Profitability Validation

Status: THEORETICAL ONLY
Backtesting: NOT PERFORMED
Live Testing: NOT PERFORMED

Missing Validations:

• Historical backtest on real market data
• Paper trading validation
• Small-scale live testing ($10-100 trades)
• Performance metrics collection and analysis

💡 RECOMMENDATIONS

Immediate Actions (Do Today)

1. Focus on security hardening before production planning
2. Implement comprehensive testing before any live deployment
3. Do not deploy any code to mainnet until security review complete
4. Start with testnet only for all initial testing

Short-term Strategy (Next 2 weeks)

1. Implement comprehensive testing before any live deployment
2. Start with small amounts ($10-100) for initial live testing
3. Gradually scale up only after proving profitability and safety
4. Monitor everything - implement comprehensive observability

Long-term Strategy (Next month)

1. Build automated testing pipeline for continuous security validation
2. Implement advanced risk management for larger capital deployment
3. Scale gradually based on proven performance metrics
4. Consider institutional-grade security for larger deployments
