# Katana Perps Revenue Methodology

## 1. Overview

Revenue is measured as the portion of trading fees that is retained by Katana Perps. This metric is used to evaluate the earnings generated from perpetual contract trading before operating expenses and token incentives are deducted. Because a supply-side fee split is not implemented for this product, 100% of the generated trading fees are retained by the protocol as revenue.

## 2. Data sources

- **Blockchain events**: `TradeExecuted` events from `Exchange` contracts on Katana Chain, covering V1 and V2 of the exchange

## 3. Step-by-step calculation

### Component A: Katana Perps trading fee extraction

- **Purpose**: Maker and taker fees are extracted from perpetual trading activity.
- **Logic**: `TradeExecuted` events are parsed from V1 and V2 `Exchange` contracts. From each event, the maker fee (`makerFeeQuantity`) and taker fee (`takerFeeQuantity`) are extracted. These raw fee amounts are normalized by decimal precision to represent USD values.
- **Key fields**: `makerFeeQuantity`, `takerFeeQuantity`

### Component B: Revenue aggregation

- **Purpose**: Total fees are aggregated and allocated to protocol revenue.
- **Logic**: The normalized maker and taker fees are summed to calculate total fees per trade. These fees are aggregated daily. Because no portion of the fees is distributed to supply-side participants, protocol revenue is set equal to 100% of the aggregated fees. Daily values are mapped to UTC day boundaries.
- **Key fields**: `fees`, `revenue`

Fee revenue retained after supply-side payouts. Before cost of revenue (e.g. L2 DA fees) and before operating expenses.
