As answered by people managing LeetCode and EdgeMarket.co.
EdgeMarket.co's answer:
EdgeMarket combines real-time blockchain monitoring with AI-powered wallet classification. We don't just show trades — we score every wallet with a Smart Score (0-100) based on historical win rate, so you know which whales actually make money.
EdgeMarket.co's answer:
Sub-2-second alert speed, 500+ tracked whale wallets, and AI-driven Smart Score that separates lucky traders from consistently profitable ones. Plus a free tier to explore before committing.
EdgeMarket.co's answer:
Prediction market traders, crypto analysts, and anyone who wants to follow smart money on Polymarket. From casual traders looking for an edge to professionals building strategies around whale movements.
EdgeMarket.co's answer:
I noticed that on Polymarket, the biggest wallets consistently outperformed the crowd. But tracking their moves manually meant hours on blockchain explorers. I built EdgeMarket to automate that — monitor every trade, classify wallets, and alert you instantly when big money moves.
EdgeMarket.co's answer:
Blockchain monitoring infrastructure, AI/ML for wallet classification and Smart Score algorithm, WebSockets for real-time feeds, Telegram Bot API for instant alerts.
