# Astar Substrate Supply-side fees Methodology

## 1. Overview

Supply-side fees measures the share of transaction fees that is distributed to service providers. For Astar Substrate, this metric is set to zero. This classification reflects the protocol's economic design, where 100% of the transaction fees generated across both the native Substrate and EVM-compatible layers are treated as protocol revenue rather than being allocated to supply-side participants.

## 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**: To determine the portion of fees shared with service providers.
- **Logic**: A constant value of zero is assigned to the metric for all timestamps. This represents the protocol's fee structure, where no portion of the collected transaction fees is distributed to supply-side participants. All underlying fees captured from `TransactionFeePaid` events or EVM-related `Withdraw` and `Deposit` events are classified as protocol revenue.
