# World Mobile Chain Earnings Methodology

## 1. Overview

Earnings represents the net profit generated by the World Mobile Chain protocol, calculated as total revenue minus total expenses. This metric measures the protocol's profitability by subtracting operational costs (L1 settlement fees and rollup fees) and token incentive payments (staking rewards) from transaction fee revenue collected on the World Mobile Chain. The calculation provides insight into the protocol's financial sustainability and operational efficiency.

## 2. Data sources

The earnings calculation relies on several raw blockchain and external data sources:
- **World Mobile Chain transaction records**: Complete transaction data including gas usage, gas prices, and transaction metadata
- **Base blockchain transaction records**: Specifically transactions sent to the World Mobile Chain sequencer address `0x3ba9426acc831cdda0dd0b537f6b4e98670bf280` for L1 settlement cost tracking
- **Staking epoch data**: World Mobile Chain staking reward distributions on both Base and Cardano networks, including epoch timestamps and reward amounts
- **End-of-day token price feeds**: USD price data for WMTX tokens (`0x3e31966d4f81c72d2a55310a6365a56a4393e98d`) and WETH tokens (`0x4200000000000000000000000000000000000006`) to enable currency conversion
- **Token metadata**: Decimal precision and symbol information for proper amount calculations

## 3. Step-by-step calculation

### Component A: Revenue calculation
- **Purpose**: Calculate total transaction fee revenue collected by World Mobile Chain
- **Logic**: Extract all transactions from World Mobile Chain transaction records. For each transaction, calculate the total gas fee by combining L2 gas fees (`gas_used` * `gas_price` / 10^18) and L1 gas fees (`l1_gas_used` * `l1_gas_price` * `l1_fee_scalar` / 10^18). Sum all gas fees by day and convert to USD using end-of-day WMTX token price feeds. This represents the total transaction fee revenue collected by the protocol.
- **Key fields**: `gas_used`, `gas_price`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`, `block_timestamp`

### Component B: Cost of revenue calculation  
- **Purpose**: Calculate operational costs including L1 settlement fees and rollup fees paid to infrastructure providers
- **Logic**: Track two types of costs. First, identify L1 settlement transactions by filtering Base blockchain transactions sent to the sequencer address. Calculate settlement costs as (`gas_used` * `gas_price` + `l1_gas_used` * `l1_gas_price`) / 10^18 and convert to USD using WETH price feeds. Second, calculate rollup fees as 20% of all World Mobile Chain gas fees, representing fees paid to Arbitrum Orbit, World Mobile, and Alchemy. Sum both cost components daily.
- **Key fields**: `gas_price`, `l1_gas_price`, `gas_used`, `l1_gas_used`, `receipt_effective_gas_price`

### Component C: Token incentives calculation
- **Purpose**: Calculate staking reward expenses distributed to network participants  
- **Logic**: Collect staking reward data from both Base and Cardano staking systems. Extract `available_rewards` from Base staking epochs and `rewards` from Cardano staking epochs. Convert reward amounts to USD using WMTX token price feeds with decimal correction applied. Sum rewards by day across both networks.
- **Key fields**: `available_rewards`, `rewards`, `epoch`, `timestamp`

### Component D: Total expenses calculation
- **Purpose**: Combine all protocol expenses into a single metric
- **Logic**: Sum the cost of revenue (L1 settlement fees + rollup fees) and token incentives for each day. This represents the total operational expenses incurred by the protocol.
- **Key fields**: Combined `cost_of_revenue` and `token_incentives` values

### Final aggregation
- **Combining components**: Revenue and total expenses are calculated independently using the same daily aggregation approach, then combined in the final earnings calculation
- **Currency conversion**: All native token amounts are converted to USD using end-of-day price feeds, with appropriate decimal correction applied based on token specifications
- **Time aggregation**: All data is aggregated to daily boundaries using timestamp truncation, ensuring consistent time alignment across all components
- **Final calculation**: Earnings equals daily revenue minus daily total expenses (cost of revenue + token incentives). Missing days are filled with zero values to maintain a continuous time series using the fill_zeros strategy
