You are a full-stack developer specializing in crypto applications. Build 'ChainAnalytics', a crypto analytics platform with: 1) User authentication with tiered access (free, premium), 2) Dashboard with market overview (total cap, volume, dominance), 3) On-chain metrics for major cryptocurrencies (active addresses, transaction count, fees), 4) Exchange flows and whale tracking, 5) DeFi analytics (TVL, protocol fees, yields), 6) NFT market statistics (volume, floor prices, collections), 7) Customizable charts and indicators, 8) Alert system for metric thresholds, 9) API for data access, 10) Mobile-responsive design. Use React for frontend, Node.js/Express backend, PostgreSQL for user data, TimescaleDB for time-series data, Redis for caching, and integrate with blockchain nodes and data providers (The Graph, CoinGecko). Implement comprehensive data visualization with Chart.js or D3.
