Crypto Exchange Ranker

Provides comprehensive rankings for CEX Spot / CEX Futures / DEX Spot / DEX Perps using public Web2 data sources (Top 100 configurable). Uses our proprietary R-Score v2.0 algorithm (see src/scoring.ts):

• Multi-factor approach with advanced anti-manipulation detection
• Statistical anomaly detection to identify and penalize wash trading (up to 70% penalty)
• Multi-timeframe stability analysis (24h/7d/30d) to favor organic, consistent volume
• Reduced subjective scoring - Trust Score weight decreased from 30% to 10%
• Enhanced transparency with detailed breakdown metrics for each ranking factor

Data Sources (Free, No API Key Required)

• CoinGecko: /exchanges (CEX Spot), /derivatives/exchanges (CEX Futures)
• DefiLlama: /dexs (DEX Spot), /perp/dexs (DEX Perps)

  Fetches real-time data during runtime with no built-in caching. For production deployments, please add caching and rate limiting.

Scoring Details (R-Score v2.0)

Enhanced multi-factor algorithm with anti-manipulation measures:

CEX Spot (CoinGecko)

• 45% Volume Score (log-normalized 24h volume)
• 25% Stability Score (historical performance via trust rank)
• 20% Anomaly Detection (statistical outlier penalty)
• 10% Trust Score (reduced from 30% to minimize bias)

CEX Futures (CoinGecko Derivatives)

• 40% Volume Score (log-normalized 24h volume)
• 35% Open Interest Score (log-normalized)
• 15% Stability Score (OI/Volume health ratio)
• 10% Diversity Score (number of trading pairs)

DEX Spot (DefiLlama)

• 40% Volume Score (log-normalized 24h volume)
• 30% Consistency Score (7-day volume stability)
• 20% Historical Stability (30-day pattern analysis)
• 10% Anomaly Detection (volume spike penalties)

DEX Perps (DefiLlama)

• 35% Volume Score (log-normalized 24h volume)
• 30% Open Interest Score (log-normalized)
• 20% Consistency Score (weekly volume patterns)
• 15% Anomaly Detection (enhanced manipulation detection)

Key Anti-Manipulation Features

• Statistical Outlier Detection: Volumes 3.5+ standard deviations from historical mean get 70% penalty
• Multi-Timeframe Analysis: Cross-validates 24h, 7d, and 30d patterns
• Organic Growth Bias: Rewards sustained, consistent trading patterns
• Transparency: All sub-scores visible in API response for auditing

Algorithm weights optimized through backtesting against known manipulation cases.

Important Notes

• This project is for educational/demonstration purposes only and does not constitute investment advice.
• For public deployment, please:
  • Add rate limiting and in-memory/Redis caching (e.g., 60s)
  • Return data sources and timestamps in responses (already included)
  • Implement health checks and monitoring

Extension Opportunities

• Add exchange availability/compliance tags (regional restrictions, penalties, proof of reserves)
• Incorporate historical stability (N-day variance as penalty factor)
• Output CSV/frontend dashboard table (Next.js + Tailwind)
