HarpoonX

HarpoonX is an AI-driven whale tracking and copy-trade intelligence platform, founded in 2025. It addresses the fact that retail users cannot filter for high-impact addresses themselves and receive no real-time buy or sell alerts. The platform identifies wallets with outsized trading volume, pushes alerts when those wallets buy or sell, and lets users monitor or quickly replicate those trades.

In narrative terms it belongs to the address tracking and copy trading branch of on-chain data tooling, differing from general market terminals in granularity: the unit of output is address behaviour rather than price charts. One naming caveat: Harpoon from Kryll is a module of a different product, and HarpoonX from DigitalXRAID is a phishing simulation training service, so the three are not the same thing. The usefulness of copying depends on data capture latency and how often the target wallet trades. Address identification runs on trade size and frequency rather than on manually entered labels.
