PolyTracker – Smart Money Tracker for Polymarket

Track whale wallet activity on Polymarket. Get instant alerts when smart money makes a move.

By the time you see it on Twitter, the edge is gone. Someone just dropped $200K on a Polymarket contract at 12 cents. The market reacts. Holders pile in. Two hours later, it's trading at 34 cents — and you're reading about it in a screenshot someone posted in a Discord you half-follow. That's the pattern. Smart money moves first. Everyone else moves after the move. PolyTracker closes that gap. WHY TRACKING SMART MONEY ON POLYMARKET IS HARD Polymarket publishes every trade on-chain. In theory, you can see everything. In practice, it falls apart: - The official UI shows top holders, not live entries as they happen - Polygonscan gives you raw transaction hashes with no market context - Twitter alpha accounts are hours behind and post selectively - Telegram groups get flooded with noise and paid shills - By the time a move surfaces on your timeline, the edge is already priced in Most traders try to solve this by refreshing leaderboards manually, bookmarking wallets, and hoping they notice something. It doesn't work. You miss the entries that matter and catch the ones that don't. Hours disappear into checking dashboards that tell you what already happened instead of what is happening right now. That's the problem PolyTracker solves. WHAT THIS EXTENSION DOES PolyTracker is a lightweight Chrome extension that watches the Polymarket wallets you care about and alerts you the moment they trade. It runs entirely in your browser. No account, no server, no middleman reading your activity, no dashboard to keep open. You don't need a Discord bot. You don't need a Dune dashboard. You don't need to keep a Polygonscan tab pinned to a second monitor. Here's what you get: Watchlist — Track up to 20 Polymarket wallet addresses at once. Paste an address, name it, and it's monitored. 1-Minute Polling — The extension quietly checks Polymarket's public API every minute in the background. No tab open. No attention required. New Trade Detection — When a watched wallet executes a new trade, you get a desktop notification within 60 seconds of the transaction landing on chain. One-Click Redirection — Click the notification and a new tab opens directly on the Polymarket event page. No searching, no copying slugs, no lost context. Custom Wallet Aliases — Rename "0x7a25...f3b2" to "CalShor", "PolyKing", or whatever nickname makes sense to you. The address stays, the label is yours. Native Desktop Alerts — Notifications use your operating system's notification center. They behave the same way Slack, Gmail, or Calendar alerts do. Silent when you're focused. Visible when they matter. Zero Setup — No login, no wallet connect, no API key, no registration flow. Install, paste, done. HOW IT WORKS 1. Click the PolyTracker icon in your Chrome toolbar 2. Paste a Polymarket wallet address (starts with 0x...) 3. Rename it if you want — "DegenTrader", "ElectionGod", anything 4. Repeat for up to 20 wallets 5. Keep Chrome running and go back to work The extension takes a baseline snapshot on the first poll. Every new trade after that triggers a desktop alert. No manual refresh. No logging in. No checking dashboards on a schedule. WHY NATIVE NOTIFICATIONS, NOT A DASHBOARD FEED A lot of tools show whale activity inside a dashboard or side panel. That works if you're sitting in front of the dashboard all day. You're not. You're in meetings, writing code, scrolling X, replying to emails, handling the rest of your life. Desktop notifications break through wherever you are. They interrupt once, fade away if you ignore them, and stay out of your way. When you click one, you land on the exact Polymarket market the whale just traded — ready to read and act. That's the entire workflow: alert, click, decide. Under ten seconds from notification to order screen. REAL SCENARIOS WHERE THIS HELPS Following a proven trader: You've identified three wallets with a track record of calling election markets early. You add them to PolyTracker. Two weeks later, one of them quietly opens a $50K position on a downballot race nobody is watching. Your desktop chimes. You click through, read the market, and decide whether to follow. Sector rotation alerts: A known crypto-narrative trader just sold their entire "Bitcoin $100K" position and moved sideways into an Ethereum ETF market. That is a signal worth knowing about in real time, not six hours later from a Twitter screenshot. Front-running the news cycle: Smart wallets often trade on information 30 to 90 minutes before it lands in mainstream crypto media. Watching their entries gives you a preview of what the timeline is about to talk about. Copy-trade discipline: You want to mirror a specific trader's positions but you don't want to stare at screens all day. PolyTracker tells you exactly when they move. You decide whether to follow. Validating your own thesis: You're bullish on an outcome. You want to know if smart money agrees. Add the wallets you respect and watch whether they are entering or fading as the event approaches. Catching exits, not just entries: Knowing when a whale exits is as important as knowing when they enter. Exits often precede a price drop by minutes. PolyTracker alerts on both sides of the trade. Research and back-testing: Building a catalog of smart money behavior? Tag wallets by strategy — arbitrageur, election trader, crypto maximalist, macro speculator — and watch how their timing differs across event categories. WHAT THIS EXTENSION DOES NOT DO - It does not scrape Polymarket's UI or inject anything into the website - It does not require you to log in, sign a message, or connect a wallet - It does not track your activity, your Polymarket balances, or your addresses - It does not send your watchlist to any server — not ours, not anyone's - It does not run analytics, telemetry, or any form of usage tracking The only permissions it uses: - storage — to save your watchlist locally in your browser - alarms — to wake up once per minute and check for new trades - notifications — to show desktop alerts when a watched wallet trades - host_permissions for Polymarket APIs — so the extension can fetch public trade data directly from data-api.polymarket.com, gamma-api.polymarket.com, and clob.polymarket.com That is the entire permission list. Everything runs on your own machine. Your watchlist never leaves your browser. There is no account, no cloud database, no sign-in. If you uninstall the extension, every byte of your data disappears with it. HOW THE POLLING ACTUALLY WORKS The extension uses Chrome's built-in alarms API to wake a background service worker once every 60 seconds. On each wake, it fetches the latest trade history for each wallet in your watchlist directly from Polymarket's public data API. It compares the newest transaction hashes against the snapshot it stored on the previous poll. If anything is new, it fires a desktop notification for the most significant trade and stores the updated snapshot. There is no scraping. There is no browser automation. There is no background tab sitting open on Polymarket. The extension only runs for a few seconds per minute and spends the rest of its time asleep. FREE TIER PolyTracker is completely free. The 20-wallet limit is the only cap, and it exists to keep API usage reasonable for Polymarket's public endpoints, not to upsell you. Most users will never track more than a handful of addresses. If you find yourself wanting more slots, you can delete wallets you no longer follow — the list updates instantly. No credit card. No trial. No paywall behind core features. WHO THIS IS FOR - Polymarket traders who want to track wallets with proven track records - Copy traders looking to mirror specific accounts without logging into external services - Analysts studying sector rotations and narrative shifts across prediction markets - On-chain researchers tracking Polygon wallet behavior over time - Event traders who want to catch whale entries before the news cycle catches up - Anyone tired of learning about big moves from delayed Twitter screenshots DESIGN PHILOSOPHY PolyTracker is built to disappear. It should be something you install once, configure in ninety seconds, and then forget about until a notification tells you something worth paying attention to is happening. The popup is clean. The alerts are quiet until they aren't. The workflow has no friction. Everything on the screen follows iOS flat design conventions — solid colors, clean typography, monoline icons, no gradients, no shadows, no noise. The extension is supposed to feel like a system utility, not a marketing surface. GETTING STARTED Install the extension, click the icon in your Chrome toolbar, paste a wallet address, and the first alert will show up the next time that wallet executes a trade on Polymarket. No account needed. No sign-up. No credit card. Just the addresses you care about and the alerts you actually want.
