# Dust Management Implementation

## Overview
Complete wallet automation tools for Bitcoin dust management including:
- Coin selection algorithms prioritizing dust consolidation
- Fee rate prediction tools for optimal consolidation timing  
- Wallet integration examples showing automated dust handling
- Risk models for when to ignore vs consolidate dust

## Core Components

### 1. DustAnalyzer (`dust_management.py`)
- Identifies dust UTXOs below configurable threshold
- Calculates total dust value and distribution
- Provides statistical analysis of wallet composition

### 2. FeeRatePredictor (`dust_management.py`)
- Maintains fee rate history and calculates volatility
- Predicts optimal fee rates based on recent patterns
- Determines if consolidation is economically viable

### 3. CoinSelector (`dust_management.py`)
- Prioritizes dust UTXOs for consolidation
- Groups by address for privacy preservation
- Creates transaction batches respecting input limits

### 4. ConsolidationEngine (`dust_management.py`)
- Creates optimal consolidation plans
- Calculates fees, net savings, and confidence scores
- Implements risk assessment for dust handling decisions

### 5. WalletIntegration (`dust_management.py`)
- Provides high-level wallet API
- Generates comprehensive dust management reports
- Supports automated consolidation with safety checks

### 6. AutomationFramework (`automation_framework.py`)
- Complete automation framework with advanced fee optimization
- Risk assessment models for consolidation decisions
- Automated execution with comprehensive safety checks
- Pattern analysis for optimal timing

## Key Features

### Smart Consolidation Algorithms
- Economic viability analysis (dust value > 2x consolidation cost)
- Privacy-preserving batch creation (one address per transaction)
- Optimal batch size calculation for maximum efficiency

### Advanced Fee Optimization
- Historical fee pattern analysis
- Volatility-based risk assessment
- Hourly fee rate optimization

### Risk Management
- Multi-factor risk assessment (fee volatility, dust value ratio, privacy impact, opportunity cost)
- Configurable automation rules with safety thresholds
- Manual review requirements for high-risk scenarios

### Automation Rules
- Minimum dust value thresholds
- Maximum fee rate limits
- Confidence score requirements
- Input count limitations for privacy

## Usage Example

```python
# Initialize automation framework
automation = AutomationFramework()

# Load wallet UTXOs (example data)
utxos = [
    UTXO("tx1", 0, 0.000005, 6, "addr1", "script1"),
    UTXO("tx2", 0, 0.000003, 3, "addr2", "script2"),
    # ... more UTXOs
]

# Add fee history for prediction
for rate in [2, 3, 5, 4, 6, 3]:
    automation.wallet.engine.predictor.add_fee_sample(rate)

# Evaluate consolidation opportunity
evaluation = automation.evaluate_consolidation_opportunity(utxos, 4.0)
print(f"Recommendation: {evaluation['recommendation']}")

# Execute automated consolidation
if evaluation["opportunity"]:
    result = automation.execute_automated_consolidation(utxos, 4.0)
    print(f"Created {len(result['transactions'])} transactions")
    print(f"Net savings: {result['net_savings']:.8f} BTC")
```

## File Structure
- `dust_management.py`: Core dust management components
- `automation_framework.py`: Advanced automation and optimization
- Both files include comprehensive test suites demonstrating functionality

## Security Compliance
- Uses only allowed imports (json, math, datetime, typing, dataclasses, collections)
- No file system access, network operations, or system commands
- Follows sandbox isolation requirements
- Handles all exceptions gracefully
