# Mythos Substrate Expenses Methodology

## 1. Overview

Expenses measures the total cost Mythos Substrate incurs to operate its business, specifically focusing on token incentives distributed to network participants. For Mythos Substrate, these costs currently consist of staking rewards paid to collators to maintain network security and consensus. These incentive payments are denominated in the native network asset and converted to USD to reflect the total economic cost of operating the infrastructure.

## 2. Data sources

- **Blockchain events**: `StakingRewardReceived` events from `collatorStaking` contracts, covering Mythos Substrate
- **External data**: End-of-day price feeds for the native asset

## 3. Step-by-step calculation

### Component A: Staking reward extraction

- **Purpose**: Captures the value of token incentives issued to network collators.
- **Logic**: `StakingRewardReceived` events are parsed from `collatorStaking` contracts on Mythos Substrate. The reward quantity is extracted from the event data and normalized by decimal precision.
- **Key fields**: `amount` (reward quantity), `block_timestamp` (event timing)

### Component B: USD conversion and aggregation

- **Purpose**: Normalizes incentive values into a standard currency for reporting.
- **Logic**: The extracted asset amounts are multiplied by end-of-day price feeds for the native asset. Daily totals are aggregated by summing the USD-denominated incentives across all relevant transactions within UTC day boundaries.
- **Key fields**: `token_incentives` (calculated USD value), `timestamp` (daily granularity)

### Component C: Final expenses formulation

- **Purpose**: Consolidates all operational costs into the final metric.
- **Logic**: The total token incentives are mapped to the expenses metric for Mythos Substrate. A zero-filling strategy is applied to ensure data continuity for all days following the product's launch.
- **Key fields**: `expenses` (final metric value)
