## 🛡️ Security Features
17+
18+
### Thread Safety & Concurrency Control
19+
- **Granular Mutex Protection**: Separate read/write/config mutexes to prevent bottlenecks
20+
- `read_mutex`: For read operations (listing orders) - allows concurrent reads
21+
- `write_mutex`: For write operations (place/cancel orders) - serializes writes
22+
- `config_mutex`: For configuration changes - protects system settings
23+
- **Atomic Operations**: Connection counts and operation tracking use atomic variables
24+
- **Rate Limiting**: Built-in rate limiting to prevent DoS attacks (configurable via constants)
25+
- **Connection Management**: Thread-safe connection pooling with proper cleanup
26+
- **Non-blocking Design**: Improved rate limiting with precise timing to avoid thread blocking
27+
28+
### Input Validation & Sanitization
29+
- **Market Name Validation**: Only alphanumeric characters, '/', '-', and '_' allowed (max 64 chars)
30+
- **Price/Size Bounds**: Maximum values enforced via centralized constants (1 billion USD/shares)
31+
- **Order ID Format**: Hexadecimal validation for order IDs (max 64 chars)
32+
- **URL Security**: Only HTTPS URLs accepted for API endpoints
33+
- **Parameter Length Limits**: All input parameters have configurable maximum length restrictions
34+
- **Comprehensive Business Logic Validation**: NaN and Infinity checks for numeric values
35+
- **Character Set Validation**: Strict whitelisting of allowed characters in all inputs
36+
37+
### Memory Safety
38+
- **Secure Memory Clearing**: Sensitive data is securely zeroed after use
39+
- **Resource Management**: Proper cleanup of HTTP connections and allocated memory
40+
- **Buffer Overflow Protection**: Response size limited to 10MB to prevent attacks
41+
- **Memory Leak Prevention**: Comprehensive resource deinitialization
42+
43+
### Error Handling & Recovery
44+
- **Comprehensive Retry Logic**: Fixed retry mechanism with proper error classification
45+
- **Exponential Backoff**: Configurable retry mechanism with exponential backoff for transient errors
46+
- **Error Classification**: Different retry strategies for different error types (network vs. auth errors)
47+
- **Enhanced Error Messages**: User-friendly error messages with emojis and context
48+
- **Graceful Degradation**: System continues operating even with partial failures
49+
- **Security-Focused Error Handling**: Error messages don't leak sensitive information
50+
- **Centralized Error Management**: All error types defined in a single comprehensive enum
51+
52+
### Centralized Configuration Management
53+
- **Constants Module**: All configuration values centralized in `blockchain/constants.zig`
54+
- **Type Safety**: Compile-time configuration validation
55+
- **Maintainability**: Single source of truth for all limits and timeouts
56+
- **Performance**: Optimized constants for rate limiting and retry logic
57+
