# Mythos Supply-side fees Methodology

## 1. Overview

Supply-side fees for Mythos represent the fees that flow to protocol supply-side participants, primarily from marketplace transactions. This metric captures fees generated by the Mythos ecosystem's marketplace activities while excluding chain-level transaction fees that flow to validators rather than protocol participants.

## 2. Data sources

- **Mythos blockchain events**: Parsed `OrderExecuted` events from the marketplace pallet containing buyer and seller fee information
- **Mythos transaction events**: `TransactionFeePaid` events from the Mythos chain (used for validation but zeroed in supply-side calculation)
- **External data**: End-of-day price feeds from CoinGecko for MYTHOS token USD conversion

## 3. Step-by-step calculation

### Component A: Marketplace fees extraction
- **Purpose**: Extract and process fees from marketplace order executions
- **Logic**: Parse `OrderExecuted` events from the Mythos marketplace pallet, extracting `buyer_fee` and `seller_fee` amounts from the event data array (positions 5 and 6). Convert from 18-decimal blockchain representation to standard units by dividing by 1e18. Sum buyer and seller fees for each order execution event.
- **Key fields**: `collection`, `item`, `seller`, `buyer`, `price`, `seller_fee`, `buyer_fee` extracted from event data

### Component B: Fee aggregation and conversion
- **Purpose**: Aggregate marketplace fees daily and convert to USD
- **Logic**: Group marketplace fees by day using timestamp truncation. Sum all fee amounts within each daily period. Convert MYTHOS token amounts to USD using end-of-day price feeds from CoinGecko with the 'mythos' identifier.
- **Key fields**: `timestamp` (daily), `fees` (aggregated MYTHOS amounts), converted to USD values

### Component C: Chain fees handling
- **Purpose**: Process chain-level transaction fees for supply-side perspective
- **Logic**: Extract `amount` and `tip` from `TransactionFeePaid` events and adjust for decimals, but explicitly set to zero for supply-side calculation since these fees flow to validators rather than protocol supply-side participants.
- **Key fields**: `amount`, `tip` from transaction fee events (set to zero in final calculation)

### Component D: DMarket fees (duplicate handling)
- **Purpose**: Include marketplace fees under DMarket product classification
- **Logic**: Create a duplicate of marketplace fees classified under the 'dmarket' product identifier, representing the same underlying marketplace fee activity viewed from a different product perspective.
- **Key fields**: Same marketplace fee data with `product_id` set to 'dmarket'

### Final aggregation
- **Combining components**: Union all fee sources including marketplace fees, dmarket fees (duplicate), and Mythos Substrate fees (zeros) to create a comprehensive view across all Mythos products
- **Currency conversion**: USD conversion applied using CoinGecko end-of-day pricing for MYTHOS token
- **Time aggregation**: Daily aggregation with timestamp truncation to day boundaries
- **Final calculation**: Apply finalization macro with zero-fill strategy for missing data points and chain availability filtering to ensure data quality and completeness
