Undertow: Crypto Flows

About

Undertow measures what price charts do not show: how much of each crypto asset actually sits in exchange wallets, and what happens when that amount moves. We read balances directly from public blockchains every 10 minutes, across 203 verified exchange wallet addresses. Nothing is licensed from a third party, which is why we can show you exactly which addresses we track and where our data has gaps. WE TELL YOU. YOU DON'T HUNT. Nobody opens an app to scan tables. Radar is a feed of measured anomalies: when an exchange reserve moves unusually, when whales cluster, when liquidations cascade, it arrives with the numbers already in it. Notifications have a daily cap and quiet hours. If you set a watchlist, only those assets reach you. WHAT YOU GET - Exchange reserves: 24h, 7d and 30d change for every tracked asset, ranked and scored against that asset's own history - Stablecoin Barometer: total stablecoins held on exchanges, broken down by exchange so you see not just how much buying power is waiting, but where - Whale transfers: classified, with internal rotations and bridge movements filtered out, and an option to hide stablecoins - Derivatives: funding, open interest and live liquidations - Premiums: cross-exchange spreads and stablecoin peg deviation - Token unlocks: with the share of circulating supply, not just the amount MEASUREMENT, NOT PREDICTION Undertow never tells you what will happen. A rising exchange balance can mean coins arrived to be sold, or that an institution moved custody. We show the measurement and the context, and leave the call to you. There are no signals, no scores, no price targets. Every number is a historical measurement you can verify. Each screen also states what it CANNOT see. Sales made over the counter or on decentralised exchanges leave no trace in these numbers, and we say so. PRIVACY BY SUBTRACTION No wallet connection. No location. No contacts, camera or microphone. No advertising ID, and we do not even ask for tracking permission, because we do no tracking. No password: sign in with Google or Apple, or use the app without an account. Data not collected cannot leak. FREE AND PREMIUM Free: top assets by movement, 24h window, 60-minute delayed data, the Stablecoin Barometer, watchlist and alerts. No ads, ever. Premium: every tracked asset, every time window, real-time data, full history, exchange-by-exchange breakdown, unlimited alerts and instant notifications. Available in 12 languages.
