# Mythos Substrate Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average fee users pay per transaction on Mythos Substrate. This metric reflects the typical cost of interacting with the network, including native transfers and activity on integrated platforms such as DMarket and Marketplace. It serves as a key indicator of network affordability and economic activity across the Mythos Substrate ecosystem.

## 2. Data sources

- **Blockchain events**: `Trade` events from `DMarket` contracts, `OrderExecuted` events from `Marketplace` contracts, and `TransactionFeePaid` events from Mythos Substrate
- **External data**: End-of-day price feeds for the native Mythos asset

## 3. Step-by-step calculation

### Component A: DMarket and Marketplace fee extraction

- **Purpose**: Captures fees generated specifically from trade activity on DMarket and Marketplace.
- **Logic**: For DMarket, the `fee` field is extracted from `Trade` events. For Marketplace, the `seller_fee` and `buyer_fee` fields are extracted from `OrderExecuted` events and summed. All identified amounts are normalized by decimal precision and aggregated to a daily frequency.
- **Key fields**: `fee`, `seller_fee`, `buyer_fee`

### Component B: Native transaction fee extraction

- **Purpose**: Captures general network transaction fees paid on Mythos Substrate.
- **Logic**: Fees are parsed from `TransactionFeePaid` events. The total fee per transaction is calculated by summing the base `amount` and the optional `tip` provided by the user. These values are normalized by decimal precision.
- **Key fields**: `amount`, `tip`

### Component C: Transaction count calculation

- **Purpose**: Determines the total volume of transactions processed by the network.
- **Logic**: Transactions are identified by counting unique extrinsic IDs from the Mythos Substrate chain. This count includes all successful operations recorded on the ledger for each daily period.
- **Key fields**: `extrinsic_id`

### Component D: Average calculation and USD conversion

- **Purpose**: Calculates the final average fee and normalizes the value to USD.
- **Logic**: The total daily fees from all sources (DMarket, Marketplace, and native network fees) are summed and then divided by the total daily transaction count. The resulting average fee is multiplied by the end-of-day price of the native Mythos asset to determine the USD value. Daily granularity is maintained using UTC day boundaries.
- **Key fields**: `fees`, `transaction_count`, `price_usd`
