OnChain: Crypto Tracker shows you what the smart money is actually doing — live whale trades, wallet x-rays, token risk scores and prices across every major chain. Free to start. No account required.
Free • iOS 16+ • Ethereum, Bitcoin, Solana, BNB Chain & Polygon
Inside the app
The whale tracking, smart-money and token-safety tools usually locked behind expensive desktop platforms — in a fast, dark, native iPhone app.




How it works
OnChain reads the blockchain itself — every large transaction, every wallet, every token contract — and turns it into signals you can act on in seconds.
Live prices for thousands of coins across Ethereum, Bitcoin, Solana, BNB Chain and Polygon. Search any coin or paste any token contract. Build a watchlist and set price alerts — all free.
A real-time feed of large buys, sells and transfers, plus a smart-money leaderboard ranking top wallets by win rate — so you see accumulation and distribution before the crowd does.
Paste a token contract to get an instant risk score and spot potential rug pulls. Paste any wallet address to x-ray its holdings, activity and behavior.
Every coin gets a 0–100 signal score built from whale flow, social sentiment and chart momentum — with a plain-English explanation of why.
Price alerts on your watchlist plus whale-move intelligence mean you hear about it when it happens on-chain — not after the candle closes.
Browse everything with no account. One-tap Sign in with Apple only when you want Pro. No wallet connection ever required — it's read-only intelligence.
Free download. Live prices, alerts and wallet lookups included. Upgrade to Pro ($5.99/mo) for real-time whale tracking, smart-money leaderboards and contract risk scores.

A crypto whale tracker monitors the blockchain for very large buys, sells and transfers made by wallets holding significant amounts of crypto ("whales"). Because these moves often precede price swings, traders watch them as an early signal. OnChain streams large transactions in real time across Ethereum, Bitcoin, Solana, BNB Chain and Polygon.
