# BMX Freestyle Supply-side fees Methodology

## 1. Overview

Supply-side fees measures the share of total fees generated by BMX Freestyle that is distributed to service providers and infrastructure partners. For BMX Freestyle, this metric specifically captures the portion of trading fees allocated to SYMMIO, the intent-based trading infrastructure provider. This value represents the cost of maintaining the protocol's execution environment and is calculated as the difference between total fees and protocol revenue.

## 2. Data sources

- **Blockchain events**: `SendQuote` and `RequestToClosePosition` events from `SymmioDiamond` contracts, and `Call` events from `MultiAccount` contracts on Base
- **External data**: End-of-day price feeds for asset valuation

## 3. Step-by-step calculation

### Component A: Trading fee extraction

- **Purpose**: Capture the total gross fees generated by trading activity on BMX Freestyle
- **Logic**: `SendQuote` and `RequestToClosePosition` events are parsed from `SymmioDiamond` contracts to identify trade openings and closings. These events are filtered through an inner join with `Call` events from `MultiAccount` contracts to isolate transactions relevant to the BMX Freestyle product. Fee amounts are calculated by multiplying the trade quantity by the market price and the specific fee basis points defined in the event data.
- **Key fields**: `quantity`, `market_price`, `trading_fee` (basis points)

### Component B: Supply-side allocation

- **Purpose**: Calculate the specific portion of fees distributed to the infrastructure provider
- **Logic**: The supply-side share is determined by applying a 40% allocation to the total fees extracted in Component A. This reflects the protocol's fee-sharing structure where 60% of fees are retained as protocol revenue and the remaining 40% is distributed to SYMMIO as the service provider for the intent-based trading engine.
- **Key fields**: `fees`, `product_id`

### Component C: USD conversion and aggregation

- **Purpose**: Normalize fee values to USD and aggregate data for reporting
- **Logic**: Calculated fee amounts are normalized by decimal precision and converted to USD using end-of-day price feeds. The resulting values are aggregated to a daily granularity using UTC day boundaries.
- **Key fields**: `block_timestamp`, `amount`, `price_usd`
