Practical Use Cases

Investment Analysis

Whale Movement Tracking

# Whale (large holder) analysis
class WhaleTracker:
    def __init__(self, min_balance_eth=1000):
        self.min_balance = min_balance_eth

    def track_whale_movements(self, timeframe='24h'):
        movements = []

        for whale_address in self.whale_addresses:
            recent_txs = get_recent_transactions(whale_address, timeframe)

            for tx in recent_txs:
                if tx.value_eth > 100:  # Movements > 100 ETH
                    movement = {
                        'whale': whale_address,
                        'direction': 'outflow' if tx.from_address == whale_address else 'inflow',
                        'amount': tx.value_eth,
                        'timestamp': tx.timestamp,
                        'potential_impact': self.assess_market_impact(tx.value_eth)
                    }
                    movements.append(movement)

        return sorted(movements, key=lambda x: x['amount'], reverse=True)

Security Analysis

Fraud Detection

// Fraudulent transaction detection system
class FraudDetector {
  async detectSuspiciousActivity(address, timeWindow = '7d') {
    const suspiciousPatterns = [];

    // Pattern 1: Abnormal transaction frequency
    const txFrequency = await this.analyzeTxFrequency(address, timeWindow);
    if (txFrequency.txPerHour > 100) {
      suspiciousPatterns.push({
        type: 'high_frequency',
        severity: 'medium',
        description: 'Abnormally high transaction frequency'
      });
    }

    return {
      address: address,
      riskScore: this.calculateRiskScore(suspiciousPatterns),
      patterns: suspiciousPatterns
    };
  }
}

Data Visualization and Reports

Charts and Graphs

// Price chart generation
const priceChartConfig = {
  type: 'candlestick',
  data: {
    timeframe: '1h',
    indicators: ['SMA20', 'SMA50', 'RSI', 'MACD'],
    volume: true
  },
  alerts: {
    price_threshold: 2500,
    volume_spike: '200%',
    whale_movement: '1000 ETH'
  }
};
