# Active users (weekly) Methodology

## 1. Overview

Active users (weekly) is defined as the number of unique addresses that make a revenue-generating transaction with Polymarket International. Active users (weekly) are measured over a 7-day rolling window. The weekly level of user engagement and trading activity on the prediction market platform is reflected by this metric. By tracking unique active addresses across both automated market maker (AMM) and order book trading interfaces, a comprehensive view of user adoption is provided. This metric is utilized to assess the growth, liquidity, and overall health of the Polymarket International ecosystem.

## 2. Data sources

- **Blockchain events**: `FPMMSell` and `FPMMBuy` events from `FixedProductMarketMaker` contracts, and `OrderFilled` events from `Exchange` and `NegRiskCtfExchange` contracts, covering Polygon

## 3. Step-by-step calculation

### Component A: Polymarket International automated market maker (AMM) activity extraction

- **Purpose**: To capture active users trading via the automated market maker interface.
- **Logic**: `FPMMBuy` and `FPMMSell` events are parsed from `FixedProductMarketMaker` contracts on Polygon. The buyer address is extracted from the `buyer` field of buy events, and the seller address is extracted from the `seller` field of sell events. These users are classified as AMM Traders. Events classified as AMM Trader are excluded if the block timestamp is on or after a specified deprecation date.
- **Key fields**: `block_timestamp`, `buyer`, `seller`, `transaction_hash`

### Component B: Polymarket International order book activity extraction

- **Purpose**: To capture active users trading via the order book interface.
- **Logic**: `OrderFilled` events are parsed from `Exchange` and `NegRiskCtfExchange` contracts across both V1 and V2 deployments on Polygon. For each event, both the maker address from the `maker` field and the taker address from the `taker` field are extracted. These users are classified as Order Book Traders.
- **Key fields**: `block_timestamp`, `maker`, `taker`, `transaction_hash`

### Component C: Weekly deduplication and aggregation

- **Purpose**: To calculate the weekly count of unique active users for Polymarket International.
- **Logic**: The extracted user addresses from both AMM and order book activities are combined. The transaction timestamps are truncated to day boundaries in UTC. Duplicate addresses are removed within each 7-day rolling window to determine the weekly distinct active users. The product identifier is defaulted to Polymarket International. Chain availability filters are applied to align the data with approved chain freshness timelines.
- **Key fields**: `block_timestamp`, `user_address`, `chain`
