# edgeX Perps Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of fees that is allocated to the service providers for edgeX Perps. The portion of total trading fees distributed to supply-side participants rather than being retained by the protocol is represented by this metric. The value allocated to external service providers and infrastructure operators is determined by subtracting protocol revenue from total fees. This measurement is utilized to evaluate the economic distribution and incentive structure of the edgeX Perps platform.

## 2. Data sources

- **External data**: Daily fee and revenue values in USD reported by the edgeX public REST API, covering StarkEx and EdgeChain

## 3. Step-by-step calculation

### Component A: Fee and revenue data extraction

- **Purpose**: To extract raw fee and revenue data for edgeX Perps.
- **Logic**: Daily fee and revenue values in USD are retrieved from the edgeX public REST API for both V1 (deployed on StarkEx) and V2 (deployed on EdgeChain) venues. The latest ingested records per day and venue are selected to ensure data freshness and accuracy.
- **Key fields**: `timestamp` (timing), `fee` (total trading fees in USD), `revenue` (protocol's retained share of fees in USD)

### Component B: Supply-side fees calculation

- **Purpose**: To calculate the portion of fees distributed to supply-side participants.
- **Logic**: Supply-side fees are calculated by subtracting protocol revenue from total trading fees. The remaining fee portion distributed to external service providers rather than being retained by the protocol is represented by this calculated value.
- **Key fields**: `fees` (total trading fees), `revenue` (protocol revenue), `fees_supply_side` (calculated supply-side fees)

### Component C: Aggregation and normalization

- **Purpose**: To aggregate supply-side fees across venues and normalize the data schema.
- **Logic**: Calculated supply-side fees are summed across all active venues and chains. The aggregated values are cast to the correct numeric data types, and the final dataset is filtered to ensure only valid chain and project identifiers are included.
- **Key fields**: `timestamp` (timing), `chain_id` (blockchain identifier), `product_id` (product identifier), `fees_supply_side` (aggregated supply-side fees)
