# Etherex rex33 rewards claimed Methodology

## 1. Overview

The REX33 rewards claimed metric measures the total value of REX33 tokens claimed by users from voting incentives and rebase rewards on the Etherex protocol. This metric tracks daily reward distribution activity, providing insight into user engagement with Etherex's governance and staking mechanisms. The calculation aggregates reward claim events from REX33 smart contracts on the Linea blockchain, converts token amounts to USD values, and presents the data as daily totals.

## 2. Data sources

The metric relies on the following raw data sources:

- **Blockchain events**: Parsed `Compounded` and `Rebased` event logs from REX33 smart contracts deployed on the Linea blockchain
- **Event data**: Transaction details including block timestamps, transaction hashes, log indices, and contract addresses from Linea blockchain
- **Token amounts**: Raw token amounts from the `amount` field in reward claim events
- **External data**: End-of-day price feeds for REX33 token (address `0xefd81eec32b9a8222d1842ec3d99c7532c31e348`) to enable USD conversion
- **Token metadata**: Decimal precision information for REX33 token to ensure accurate amount calculations

## 3. Step-by-step calculation

### Component A: Raw reward claims extraction
- **Purpose**: Identify and extract all REX33 reward claim events from Linea blockchain
- **Logic**: Parse blockchain event logs for two specific event types: `Compounded` events (from voting incentives) and `Rebased` events (from rebase rewards). Filter to include only valid events by excluding those marked as removed. Extract key transaction details including block timestamp, transaction hash, log index, and contract address. Cast the `amount` field to high-precision numeric format to preserve token precision.
- **Key fields**: `block_timestamp` for timing, `amount` for reward quantities, `address` for contract identification, transaction identifiers for deduplication

### Component B: Data standardization and aggregation
- **Purpose**: Standardize the extracted events and aggregate by day
- **Logic**: Add standardized metadata to each event including chain identifier as 'linea', product identifier as 'Constant Product', and version as 'v2'. Apply daily timestamp truncation to group events by calendar day. Set the token address to the hardcoded REX33 contract address. Sum all reward amounts within each day to calculate total daily rewards claimed.
- **Key fields**: `timestamp` truncated to day level, `chain_id` as 'linea', `product_id` as 'Constant Product', `token_address` as the REX33 contract address, aggregated `rex33_rewards_claimed` amounts

### Component C: Currency conversion and decimal correction
- **Purpose**: Convert REX33 token amounts to USD values with proper decimal handling
- **Logic**: Apply the convert to USD macro which looks up end-of-day prices for REX33 tokens and converts the native token amounts to USD equivalents. Simultaneously correct for token decimal precision to ensure amounts reflect actual token values rather than raw blockchain integer values. This process uses the token's decimal configuration to properly scale amounts.
- **Key fields**: USD-converted `rex33_rewards_claimed` values, price data from end-of-day feeds, decimal-corrected amounts

### Final aggregation
- **Combining components**: The process flows sequentially from raw event extraction through standardization to USD conversion, with each step building on the previous component's output
- **Currency conversion**: REX33 token amounts are converted to USD using end-of-day price feeds specific to the REX33 token address, applied after decimal correction
- **Time aggregation**: All reward claims within each calendar day are summed to produce daily totals, using timestamp truncation to day boundaries
- **Final calculation**: The metric represents the total USD value of REX33 rewards claimed each day across all users and all reward types (voting incentives and rebase rewards). Gap filling with zeros ensures continuous daily series. Chain availability filters ensure data completeness and quality before final output.
