# Katana Chain Supply-side fees Methodology

## 1. Overview

Supply-side fees represents the share of fees that is distributed to service providers. For Katana Chain and its associated products—including Katana Perps, Katana Vault Bridge, Katana AUSD Yield, and vKAT—this metric is set to zero. No external supply-side participants are compensated through on-chain fee allocations for the chain infrastructure, vault bridge, AUSD yield, or vKAT exit fees. For Katana Perps, maker spreads are determined off-chain and are not observable on-chain, while negative maker fee rebates are already netted directly into the primary fees metric.

## 2. Data sources

- **None**: This metric is set to a constant value of zero and no blockchain events are consumed

## 3. Step-by-step calculation

### Component A: Supply-side fee allocation

- **Purpose**: Assigns the portion of fees distributed to external service providers.
- **Logic**: A constant value of zero is applied to the supply-side fees metric for Katana Chain and all associated products. This reflects that no on-chain fee revenue is distributed to external supply-side participants, as all infrastructure and operational fees are retained or processed without external service provider payouts.

The network uses pessimistic proofs via the AgglayerGateway for settlement on Ethereum, with vault bridges for cross-chain asset transfers.

Katana Network provides a scalable execution environment connected to Ethereum through the Agglayer interoperability layer.
