# Heima Token incentives Methodology

## 1. Overview

Token incentives measures the total USD value of staking rewards distributed daily on the Heima parachain ecosystem. This metric captures the monetary incentives provided to network participants through two primary staking mechanisms: parachain staking rewards and score-based staking rewards. The calculation aggregates native LIT token rewards distributed through blockchain events and converts them to USD values using end-of-day price feeds.

## 2. Data sources

The calculation uses several key data sources:
- **Heima parachain event logs**: Parsed blockchain events from the Heima parachain capturing staking reward distributions and claims
- **Staking reward events**: Two specific event types from the parachain - `Rewarded` events from the `parachainStaking` pallet and `RewardClaimed` events from the `scoreStaking` pallet
- **Event data arrays**: JSON-formatted event parameters containing reward amounts in the second array element
- **End-of-day price feeds**: CoinGecko price data for the LIT token used for USD conversion
- **Token metadata**: Decimal precision information for the LIT token (18 decimals)

## 3. Step-by-step calculation

### Component A: Staking rewards extraction
- **Purpose**: Extracts and processes raw staking reward events from the Heima parachain
- **Logic**: Filters Heima parachain events for two specific reward types. First, identifies `Rewarded` events from the `parachainStaking` pallet which represent standard parachain staking rewards. Second, captures `RewardClaimed` events from the `scoreStaking` pallet which represent score-based staking rewards. For each qualifying event, extracts the reward amount from the second element of the `event_data` JSON array and converts from the native 18-decimal precision to standard token units by dividing by 1e18
- **Key fields**: `block_timestamp` for timing, `extrinsic_id` for transaction reference, and `amount` for the converted reward value in LIT tokens

### Component B: Daily aggregation and USD conversion  
- **Purpose**: Aggregates daily reward totals and converts native token amounts to USD values
- **Logic**: Groups all staking rewards by day using timestamp truncation to daily boundaries. Assigns the chain identifier as `heima` and product identifier as `heimachain` for all records. Sums all reward amounts within each day to get the total daily token incentives distributed. Converts the daily LIT token amounts to USD using CoinGecko price feeds with the token identifier `heima`, matching prices to the corresponding day of reward distribution
- **Key fields**: `timestamp` truncated to day, `timestamp_grain` set to `day`, `chain_id` as `heima`, `product_id` as `heimachain`, and `token_incentives` containing the USD-converted daily total

### Final aggregation
- **Combining components**: The daily aggregated USD amounts from Component B flow directly into the final metric calculation without additional combining or summing
- **Currency conversion**: USD conversion occurs at the daily aggregation level using end-of-day CoinGecko price feeds for the LIT token, ensuring consistent daily USD values
- **Time aggregation**: All rewards within each calendar day are summed together, with timestamp boundaries set at daily granularity  
- **Final calculation**: The metric applies a fill-forward strategy to handle missing dates, ensuring continuous daily time series data. Chain availability filters are applied to restrict results based on configuration settings. The final output represents the total USD value of staking rewards distributed each day across both parachain staking and score staking mechanisms on the Heima network
