+# MEV Bot Security Audit
+
+Perform a comprehensive security audit of the MEV bot focusing on: $ARGUMENTS
+
+## Security Audit Checklist:
+
+### 1. **Code Security Analysis**
+```bash
+# Static security analysis
+gosec ./...
+
+# Dependency vulnerabilities
+go list -json -m all | nancy sleuth
+
+# Secret scanning
+git-secrets --scan
+```
+
+### 2. **Input Validation Review**
+- Transaction data parsing validation
+- RPC response validation
+- Configuration parameter validation
+- Mathematical overflow/underflow checks
+- Buffer overflow prevention
+
+### 3. **Cryptographic Security**
+- Private key handling and storage
+- Signature verification processes
+- Random number generation
+- Hash function usage
+- Encryption at rest and in transit
+
+### 4. **Network Security**
+- RPC endpoint authentication
+- TLS/SSL configuration
+- Rate limiting implementation
+- DDoS protection mechanisms
+- WebSocket connection security
+
+### 5. **Runtime Security**
+- Memory safety in Go code
+- Goroutine safety and race conditions
+- Resource exhaustion protection
+- Error information disclosure
+- Logging security (no sensitive data)
+
+## Specific MEV Bot Security Areas:
+
+### **Transaction Processing**
+- Validate all transaction inputs
+- Prevent transaction replay attacks  
+- Secure handling of swap calculations
+- Protection against malicious contract calls
+
+### **Market Data Integrity**
+- Price feed validation
+- Oracle manipulation detection
+- Historical data integrity
+- Real-time data verification
+
+### **Financial Security**
+- Gas estimation accuracy
+- Slippage protection
+- Minimum profit validation
+- MEV protection mechanisms
+
+## Output Requirements:
+- Detailed security findings report
+- Risk assessment (Critical/High/Medium/Low)
+- Remediation recommendations
+- Implementation timeline for fixes
+- Security testing procedures
