  • Pull holdings breakdown, allocation, and P/L charts.
  • Perform further analytics on top of your CoinStats data, such as:
    • Backtesting strategies against your actual holdings.
    • Tracking asset allocation trends over time.
    • Running risk metrics, correlation analysis, or performance benchmarking.
  • Embed your CoinStats portfolio directly in custom apps.

Market Data: On-Chain + Exchange Coverage

Access listings and metadata for all supported cryptocurrencies, plus prices, market caps, volumes, and historical charts.

Coins / Listings

Coverage

  • Supports pretty much any cryptocurrency with at least ~$50k liquidity and trading volume.
  • Unified data across 120+ blockchains and 200+ exchanges.

CoinStats unifies data across 120+ blockchains—from major EVM networks (Ethereum, BNB Chain, Polygon, Arbitrum, Avalanche) to non-EVM chains like Solana and Bitcoin.
