# Katana Supply-side fees Methodology

## 1. Overview

The share of fees that goes to service providers is represented by supply-side fees. For Katana, this metric is set to zero across all products, including Katana Chain, Katana Perps, Katana AUSD Yield, Katana Vault Bridge, and vKAT. No external supply-side participants are supported on Katana Chain, Katana Vault Bridge, Katana AUSD Yield, or vKAT. For Katana Perps, maker spreads are determined off-chain and are not observable, while negative maker fee rebates are already netted directly into total fees.

## 2. Data sources

- **None**: This metric is set to a constant value and does not consume blockchain events

## 3. Step-by-step calculation

### Component A: Supply-side fee assignment

- **Purpose**: Assign supply-side fees for all Katana products
- **Logic**: A constant value of zero is assigned to the supply-side fees metric for all products, including Katana Chain, Katana Perps, Katana AUSD Yield, Katana Vault Bridge, and vKAT. No external supply-side allocations are distributed by these products, or they are otherwise unobservable on-chain.
