# Katana Perps Notional trading volume Methodology

## 1. Overview

Notional trading volume is measured as the total value of derivative contracts executed on a decentralized derivatives exchange. Since trading fees are paid on each trade, this metric correlates with the ability of the project to generate fees and revenue. For Katana Perps, the aggregate value of all perpetual contracts traded across both V1 and V2 of the exchange is captured. Trades are executed by buyers and sellers, and the volume is denominated in USD.

## 2. Data sources

- **Blockchain events**: `TradeExecuted` events from `Exchange` contracts (V1 and V2), covering Katana Network

## 3. Step-by-step calculation

### Component A: Trade execution extraction

- **Purpose**: Extract trade details from the blockchain events
- **Logic**: `TradeExecuted` events are parsed from `Exchange` contracts across V1 and V2 deployments. For each event, the quote quantity, buyer address, seller address, maker fee, and taker fee are extracted.
- **Key fields**: `quoteQuantity`, `buyWallet`, `sellWallet`, `makerFeeQuantity`, `takerFeeQuantity`

### Component B: Normalization and USD conversion

- **Purpose**: Normalize the raw trade quantities to USD values
- **Logic**: Raw quote quantities are cast to numeric values and normalized by decimal precision to determine the USD value of each trade. Maker and taker fees are normalized using the same decimal precision factor.
- **Key fields**: `notional_volume_usd`, `maker_fee_usd`, `taker_fee_usd`

### Component C: Daily aggregation and zero-filling

- **Purpose**: Aggregate trade volumes to daily intervals and ensure continuous data
- **Logic**: Normalized trade volumes are aggregated by truncating block timestamps to daily granularity. The daily volumes are summed for Katana Perps. Missing days in the time series are filled with zeros to ensure a continuous daily record.
- **Key fields**: `timestamp`, `notional_trading_volume`
