## 🔐 Security Features

### Credential Management
```rust
// Secure storage using OS keychain
let mut storage = SecureWalletStorage::new()?;
storage.store_private_key(address, private_key)?;
storage.store_mnemonic(wallet_id, mnemonic)?;
```

### Session Management
```rust
// Configurable session with timeout
let config = SessionConfig {
    max_duration: Duration::hours(24),
    idle_timeout: Duration::minutes(30),
    require_reauth: true,
};
let session = manager.create_session(user_id)?;
```

### Network Failover
```rust
// Automatic RPC endpoint failover
let failover = NetworkFailoverBuilder::new()
    .add_endpoints(vec![endpoint1, endpoint2, endpoint3])
    .health_check_interval(Duration::from_secs(60))
    .build();
```

## 📈 Monitoring & Observability

### Structured Logging
```rust
// JSON formatted logs for production
let logger = StructuredLogger::new()
    .with_context("operation", "transfer")
    .with_context("user", user_id);
logger.info("Transaction initiated");
```

### Metrics Collection
```rust
// Prometheus-compatible metrics
collector.increment("transactions_total", vec![
    ("status", "success"),
    ("network", "mainnet"),
]);
```

### Performance Tracking
```rust
// Automatic performance logging
let timer = PerformanceLogger::new("api_call")
    .with_threshold(Duration::from_secs(1));
// ... operation ...
timer.complete();
```

## 🚀 Deployment & Operations

### Production Deployment
```bash
# Full deployment with health checks
./scripts/deploy.sh deploy

# Rollback to previous version
./scripts/deploy.sh rollback

# Verify deployment status
./scripts/deploy.sh verify
```

### Auto-Update System
```bash
# Check for updates
./scripts/update.sh check

# Run update daemon
./scripts/update.sh daemon

# Manual update
./scripts/update.sh apply <update_file> <version>
```

### Configuration Management
```toml
# production.toml
[security]
session_timeout_minutes = 30
enable_2fa = true
use_hardware_security = true

[network]
mainnet_endpoints = [
    "https://mainnet1.neo.coz.io:443",
    "https://mainnet2.neo.coz.io:443",
]
request_timeout_seconds = 30
max_retries = 3
```
