# edgeX Perps Fees Methodology

## 1. Overview

Fees are defined as the total trading fees paid by users to trade perpetual contracts on edgeX Perps. This metric is utilized to represent the total economic value generated by the platform's trading activity. Trading fees are collected across different deployment venues, including StarkEx and EdgeChain, and are used in the evaluation of the overall financial performance and usage of edgeX Perps.

## 2. Data sources

- **External data**: Daily fee and revenue data reported via the edgeX public REST API, covering StarkEx and EdgeChain

## 3. Step-by-step calculation

### Component A: Venue data extraction

- **Purpose**: To capture raw fee data reported for each edgeX Perps deployment venue
- **Logic**: Raw daily fee data is extracted from the edgeX scraper tables for both the V1 venue on StarkEx and the V2 venue on EdgeChain. The reporting timestamp, venue identifier, chain identifier, fee values in USD, and the ingestion timestamp are retrieved during this process.
- **Key fields**: `timestamp` (timing), `fee` (fee quantities), `venue` (venue identification), `inserted_timestamp` (ingestion timing)

### Component B: Deduplication and normalization

- **Purpose**: To ensure data uniqueness and correct data types for downstream metrics
- **Logic**: The extracted records are deduplicated per day and venue by retaining only the latest record based on the ingestion timestamp, with ties resolved by selecting the highest reported fee and revenue values. The fields are then cast to their canonical data types, converting timestamps to standard format and fee values to high-precision numeric values.
- **Key fields**: `timestamp` (timing), `fee` (fee quantities), `inserted_timestamp` (ingestion timing)

### Component C: Final aggregation and gap filling

- **Purpose**: To aggregate fees by chain and product, and to ensure a continuous daily time series
- **Logic**: Fee values are aggregated by day, product identifier, and chain identifier. A zero-filling strategy is applied to ensure that any days with missing data in the time series are populated with zero values, maintaining a continuous daily record for edgeX Perps.
- **Key fields**: `timestamp` (timing), `fees` (aggregated fee quantities), `chain` (chain identification), `product` (product identification)

Derivative exchanges

edgeX is a high-performance decentralized perpetual futures and spot trading platform incubated by Amber Group, combining an off-chain matching engine with on-chain settlement. Its original venue ran on StarkEx zero-knowledge rollups and wound down in August 2026. edgeX V2 is a full rebuild on EDGE Chain, an application-specific Arbitrum rollup that settles to Ethereum, using Circle's CCTP for native USDC deposits and reaching a peak throughput of 300,000 orders per second at sub-100 millisecond order latency.
