# ChainHint

> ChainHint is a blockchain forensics platform for tracing stolen cryptocurrency. Paste a wallet address — get a fund-flow graph, entity attribution, and risk scoring in seconds. Used by fraud lawyers, security researchers, and crypto theft victims.

ChainHint automates the first-response phase of crypto incident investigation: it traces funds across hops using BFS (breadth-first search), identifies known entities (exchanges, mixers, bridges, sanctioned addresses), detects cross-chain transfers, and generates AI-powered investigation reports.

Supported chains: Ethereum, Bitcoin, Polygon, Arbitrum, Optimism, Base.
Entity database: ~1M labeled addresses (OFAC SDN, Scam Sniffer, USDT/USDC blacklists, Etherscan labels, ENS, WalletExplorer BTC clusters, Arkham Intel).
