Wraps ChainAnalyzer's blockchain forensics API into Claude, giving you AML risk scoring, sanctions screening, and transaction tracing across Bitcoin, Ethereum, Polygon, Avalanche, Solana, and five other chains. The six tools include address risk checks, OFAC/FATF sanctions lookups, transaction flow analysis with ML anomaly detection, CoinJoin pattern recognition for Bitcoin, Neo4j powered wallet clustering, and batch screening for up to 50 addresses at once. Auth works three ways: subscription API keys, pay per request via x402 USDC payments on Base or Solana, or dev mode for local testing. Reach for this when you need compliance checks or forensic analysis in crypto workflows without building your own chain indexing and rule engine.
