# Introduction

> PolyEdge is an advanced API service that gives professional traders, developers, and data analysts a definitive edge in Polymarket prediction markets.

PolyEdge provides millisecond-level access to Polymarket order flow, smart money analytics, and deep wallet data — everything you need to trade smarter or build powerful market tools.

<Info>
  **Data scope and calculations**

  * **Polymarket v2**: PolyEdge covers all Polymarket v2 transaction data. It currently does not include Polymarket v1 data.
  * **PnL calculations**: All profit and loss (PnL) metrics are net of transaction fees. Trading fees are automatically deducted from the calculations.

## Who it's for

* **Professional traders** who want to track smart money, monitor live order flow, and act on real-time signals before trades settle.
* **Polymarket developers** building bots, copy-trading systems, or automated strategies that react to live mempool data.
* **Data analysts** creating dashboards, backtesting models, or conducting research on Polymarket trader behavior and market dynamics.

## Key features

**Real-time mempool streams**

Subscribe to a live Server-Sent Events (SSE) stream of Polymarket orders before they settle on-chain. Filter by trader address, market tag, USDC size, price range, and more.

**Smart money leaderboards**

Query a ranked leaderboard of the top Polymarket traders by PNL, ROI, win rate, or market count. Filter by time frame (1H to 30D), market category, and activity recency to find the traders worth following.

**Wallet analytics**

Drill into any trader's full history: per-market performance, individual order records, and detailed profile metadata — all from a single wallet address.
