Undertow — Crypto Flows

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. Balances are read 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.

Nobody opens an app to scan tables, so Radar delivers a feed of measured anomalies — unusual reserve moves, whale clustering, cascading liquidations — with the numbers already worked out, capped at five alerts a day by default and silent between 11pm and 8am unless you change it. Undertow never tells you what will happen: a rising exchange balance can mean coins arrived to be sold, or that an institution moved custody, and every screen states plainly what it cannot see, such as over-the-counter or decentralised-exchange trades. There is no wallet connection, no location, no contacts, camera, microphone or advertising ID — data not collected cannot leak — and the app works free with no ads, with Premium unlocking every asset, real-time data and unlimited alerts.
