# Prime Numbers Expenses Methodology

## 1. Overview

The expenses metric measures the total USD value of token incentives paid out by PrimeNumbers protocol daily. This represents the protocol's operational costs for rewarding users across its lending and staking products. The metric combines incentive payments from both the lending protocol (via MultiFeeDistribution rewards) and the Prime Staking product, providing a comprehensive view of the protocol's daily reward expenditures.

## 2. Data sources

- **XDC blockchain events**: Parsed `MultiFeeDistribution_Withdrawn` events from the PrimeNumbers lending protocol's reward distribution contract
- **XDC blockchain events**: Parsed `PrimeStakedXDC_RewardPaid` events from the Prime Staking contract for staking rewards
- **External price data**: End-of-day XDCE token price feeds from CoinGecko API
- **Token metadata**: XDCE token contract address (`0xffa04f091128fb89d3b1ecd0149dc677dfae1c69`) and decimal specifications

## 3. Step-by-step calculation

### Component A: Lending protocol token incentives
- **Purpose**: Captures reward distributions from the PrimeNumbers lending protocol
- **Logic**: Extracts `MultiFeeDistribution_Withdrawn` events from XDC blockchain, focusing on the `receivedAmount` field which represents XDCE tokens withdrawn as rewards. Each event is tagged with the specific token address, chain, and categorized under the lending business line. The raw amounts are processed through decimal correction and USD conversion using end-of-day XDCE token prices from CoinGecko.
- **Key fields**: `receivedAmount` (reward amount in XDCE tokens), `block_timestamp` (event timing), `token_address` (XDCE contract address), `transaction_hash` and `log_index` (for event identification)

### Component B: Prime Staking token incentives
- **Purpose**: Captures staking rewards paid out through the Prime Staking product
- **Logic**: Processes `PrimeStakedXDC_RewardPaid` events from XDC blockchain, extracting the `reward` field representing XDCE token rewards for staking participants. Raw amounts are normalized by dividing by 1e18 to account for token decimals, then converted to USD using XDCE prices from CoinGecko price feeds. Events are categorized under the Prime Staking product.
- **Key fields**: `reward` (staking reward amount), `block_timestamp` (timing), `transaction_hash` and `log_index` (event identification)

### Final aggregation
- **Combining components**: Both lending and staking incentive streams are combined through a union operation, creating a unified dataset of all token incentive payments across PrimeNumbers products
- **Currency conversion**: All XDCE token amounts are converted to USD using end-of-day prices from CoinGecko, with proper decimal normalization applied (dividing by 1e18 for 18-decimal XDCE tokens)
- **Time aggregation**: Events are aggregated daily using timestamp truncation, summing all incentive payments within each 24-hour period
- **Final calculation**: The total daily USD value of combined lending and staking incentives becomes the expenses metric, representing the protocol's daily operational cost for user rewards. Time series gaps are filled with zeros to ensure complete daily coverage.
