# Katana Perps Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of fees that is distributed to service providers. For Katana Perps, this metric is set to zero. No portion of trading fees is distributed to external supply-side participants on-chain. Maker spreads are configured off-chain and are not observable, while any negative maker fee rebates are already netted directly into the primary fees metric.
