# Felix OIL Revenue Methodology

## 1. Overview

This page covers the OIL market (`flx:OIL`) on Felix, one of the markets deployed under the `flx` namespace on Hyperliquid HyperCore. The calculation is identical across all Felix markets; the figures on this page are scoped to the OIL market.

Revenue measures the portion of trading fees retained by Felix across the protocol's perpetual markets. These earnings are represented by the protocol's share of transaction fees generated from trade executions, before operating expenses or token incentives are deducted. By capturing the realized deployer fees from perpetual contract fills, the direct economic value captured by the protocol is quantified. All revenue is collected in Hyper USD and utilized to evaluate the financial performance of the protocol.

## 2. Data sources

- **Blockchain events**: `node_fills` events from `hypercore` contracts, covering Hyperliquid
- **External data**: End-of-day price feeds for Hyper USD

## 3. Step-by-step calculation

### Component A: Perpetual trade fill extraction

- **Purpose**: Identify and extract trade fills executed across the protocol's perpetual markets
- **Logic**: Trade fill events are parsed from `node_fills` events on the Hyperliquid chain. Transactions are filtered to isolate Felix perpetual markets by identifying assets carrying the specific protocol prefix. Only trade fills settled in Hyper USD are included in the dataset.
- **Key fields**: `coin`, `fee_token`, `fee`, `deployer_fee`

### Component B: Protocol revenue calculation

- **Purpose**: Determine the protocol's share of fees from each trade fill
- **Logic**: Protocol revenue is calculated on a per-fill basis using the realized deployer fee. For historical fills where the explicit deployer fee is not populated, a fallback rate of 50% of the total transaction fee is applied, representing the protocol's standard take rate ceiling. These individual revenue values are then summed to determine the total daily revenue.
- **Key fields**: `deployer_fee`, `fee`

### Component C: Normalization and aggregation

- **Purpose**: Standardize revenue values and aggregate them to a daily granularity
- **Logic**: Revenue amounts are normalized by decimal precision and converted to USD using end-of-day price feeds. The normalized values are aggregated by day, chain, and product using UTC day boundaries. Missing days within the time series are filled with zero values to ensure data continuity.
