# Active users (weekly) Methodology

## 1. Overview

Active users (weekly) is calculated as the number of unique addresses that make a revenue-generating transaction with a project over a 7-day rolling window. User activity is monitored to evaluate adoption and engagement across both the underlying blockchain infrastructure and specific applications. For Katana Network, active users are tracked at the chain level for Katana Chain and at the application level for Katana Perps. Unique addresses are aggregated weekly to represent active participation.

## 2. Data sources

- **Blockchain events**: Transaction sender addresses from native transactions, and `TradeExecuted` events from `Exchange` contracts, covering Katana Chain

## 3. Step-by-step calculation

### Component A: Katana Chain transaction tracking

- **Purpose**: Capture unique transaction senders at the blockchain level
- **Logic**: Transaction sender addresses are extracted from the transaction metadata of Katana Chain. These addresses are classified as transaction senders and mapped to Katana Chain.
- **Key fields**: `block_timestamp` (timing), `from_address` (user address)

### Component B: Katana Perps trader tracking

- **Purpose**: Capture unique traders interacting with the perpetual exchange
- **Logic**: `TradeExecuted` events are parsed from `Exchange` contracts across V1 and V2 deployments. Buyer and seller addresses are extracted from each trade event and combined into a single set of active wallets. These addresses are classified as traders and mapped to Katana Perps.
- **Key fields**: `block_timestamp` (timing), `buyWallet` (buyer address), `sellWallet` (seller address)

### Component C: Weekly aggregation and deduplication

- **Purpose**: Consolidate and deduplicate active addresses into weekly metrics
- **Logic**: Active addresses from both Katana Chain transaction senders and Katana Perps traders are aggregated per 7-day window using UTC boundaries. Duplicate addresses within each product and user type category are removed to ensure a unique count of active users (weekly). Chain availability filters are applied to align the final dataset with approved data freshness boundaries.
