# IoTeX Token incentives Methodology

## 1. Overview

IoTeX token incentives measures the daily USD value of IOTX tokens distributed as rewards through the IoTeX blockchain's reward system. This metric captures various types of incentive payments including block rewards for validators, epoch rewards for staking participants, foundation bonuses, and priority bonuses. The metric provides insight into the economic incentive structure of the IoTeX ecosystem and the daily cost of securing and operating the network.

## 2. Data sources

- **IoTeX blockchain event logs**: Raw event logs from the IoTeX blockchain, specifically from the reward contract at address `0xa576c141e5659137ddda4223d209d4744b2106be`
- **End-of-day price feeds**: Daily IOTX token price data for USD conversion
- **IoTeX native token metadata**: Token information including decimal places and contract details for the native IOTX token

## 3. Step-by-step calculation

### Component A: Reward log extraction and decoding
- **Purpose**: Extract and decode reward distribution events from the IoTeX blockchain
- **Logic**: The calculation begins by filtering IoTeX blockchain event logs to identify reward distribution events from the specific reward contract address. These raw log entries contain encoded reward data that must be decoded using a custom function to extract structured reward information. The decoding process extracts key details including reward type identifiers, recipient addresses, and reward amounts in both RAU (the smallest IOTX unit) and IOTX denominations.
- **Key fields**: `block_timestamp` for timing, `reward_type_id` for categorization, `amount_iotx` for reward quantity, `recipient_address` for reward recipient

### Component B: Reward type categorization and daily aggregation
- **Purpose**: Categorize rewards by type and aggregate to daily totals
- **Logic**: The decoded reward data is processed to map numeric reward type identifiers to human-readable categories. Type 0 represents block rewards distributed to validators, type 1 represents epoch rewards for staking participants, type 2 represents foundation bonus payments, and type 3 represents priority bonus distributions. The rewards are then aggregated by day using timestamp truncation, with each reward type maintaining its categorization. The aggregation preserves the reward amount in IOTX tokens while establishing daily time boundaries.
- **Key fields**: `timestamp` truncated to day boundaries, `reward_type` as categorized text, `token_incentives` as IOTX amounts

### Component C: Currency conversion to USD
- **Purpose**: Convert IOTX token amounts to USD values using market prices
- **Logic**: The daily IOTX reward amounts are converted to USD using end-of-day price feeds. This conversion process handles decimal precision correctly for the IOTX token and applies the appropriate exchange rate for each day. The conversion ensures that the final metric reflects the economic value of the incentives distributed rather than just token quantities.
- **Key fields**: USD-denominated `token_incentives` values with proper decimal handling

### Final aggregation
- **Combining components**: The USD-converted reward amounts are processed through a standardization framework that ensures consistent schema formatting and data validation
- **Currency conversion**: Uses end-of-day IOTX/USD exchange rates applied to the daily reward totals
- **Time aggregation**: Daily boundaries are established using timestamp truncation, with each day representing the total incentives distributed during that 24-hour period
- **Final calculation**: The final metric value represents the total USD value of IOTX tokens distributed as incentives on each day, categorized by reward type and aggregated across all recipients. Gap-filling logic ensures continuous time series data by inserting zero values for days with no reward distributions, and chain availability filters ensure data quality and completeness.
