# XDC Network Expenses Methodology

## 1. Overview

The XDC expenses metric measures the total USD value of token incentives distributed by the XDC Network through its Surge Program. This metric captures the protocol's spending on user incentives, treating distributed tokens as operational expenses. The calculation aggregates all token incentive claims from the merkle-based distribution system, converts them to USD, and presents them as daily totals.

## 2. Data sources

- **XDC blockchain events**: Parsed `Distributor_Claimed` events from XDC Network's incentive distribution contract, capturing when users claim token rewards
- **Token metadata**: Token contract information including decimal places for proper amount normalization
- **External price data**: End-of-day token price feeds for USD conversion of distributed token amounts

## 3. Step-by-step calculation

### Component A: Token incentive event extraction
- **Purpose**: Capture all token incentive claims from the XDC Network Surge Program
- **Logic**: Extract `Distributor_Claimed` events from the XDC blockchain distributor contract. Each event contains the claiming account address, token contract address, and claimed amount. Filter for distinct events to avoid duplicates using block timestamp, transaction hash, and log index as unique identifiers.
- **Key fields**: `block_timestamp` for timing, `address` for the claiming account, `token` for the incentive token address, `amount` for the raw claimed quantity

### Component B: Daily aggregation and normalization
- **Purpose**: Group incentive claims by day and normalize token amounts
- **Logic**: Truncate event timestamps to daily boundaries and aggregate all claims within each day. Apply decimal correction using token metadata to convert raw blockchain amounts to actual token quantities. Classify all incentives under the blockchain business line and layer-1 market sector.
- **Key fields**: `timestamp` truncated to day, `token_address` for identifying specific tokens, `amount` after decimal normalization

### Component C: USD conversion
- **Purpose**: Convert token amounts to USD values for standardized reporting
- **Logic**: Join normalized token amounts with end-of-day price feeds to convert each token quantity to its USD equivalent. Use the price corresponding to the claim date for accurate valuation.
- **Key fields**: `amount` converted to USD value using appropriate exchange rates

### Final aggregation
- **Combining components**: Sum all USD-denominated token incentive amounts for each day across all token types and claiming accounts
- **Currency conversion**: All token amounts are converted to USD using end-of-day price feeds matched to the claim date
- **Time aggregation**: Daily boundaries are used with timestamp truncation to the start of each day
- **Final calculation**: The expenses metric equals the total daily USD value of all token incentives distributed through the XDC Network Surge Program, with zero-filling applied to days without any incentive distributions to maintain a continuous time series
