# Katana Vault Bridge Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of fees that is distributed to service providers. For Katana Vault Bridge, this metric is set to zero by design. No external supply-side participants or liquidity providers are allocated a share of the yield collected by the vault bridge contracts. All generated yield is retained by the protocol or directed to protocol-controlled vaults, resulting in no supply-side fee distribution to external service providers.

## 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 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 Vault Bridge. This reflects the protocol design where no portion of the harvested yield is distributed to external supply-side participants.
