# World Mobile Chain Fees Methodology

## 1. Overview

This metric calculates the total transaction fees collected by the World Mobile Chain network on a daily basis, denominated in USD. The fees represent on-chain transaction costs paid by users to execute transactions on the World Mobile Chain, including both Layer 2 execution fees and Layer 1 data availability fees. This metric specifically captures network-level fees and excludes any service fees paid directly to World Mobile as a company.

## 2. Data sources

The calculation relies on the following raw data sources:
- **World Mobile Chain transaction records**: Complete transaction data including gas usage metrics, pricing information, and fee scalars for all transactions executed on the World Mobile Chain
- **Base chain token metadata**: Token information for the WMTX token (`0x3e31966d4f81c72d2a55310a6365a56a4393e98d`) used as the fee token, since World Mobile Chain does not have a native token address
- **End-of-day price feeds**: USD price data for the WMTX token to enable currency conversion of fee amounts

## 3. Step-by-step calculation

### Component A: Transaction data extraction
- **Purpose**: Extract and standardize raw transaction data from World Mobile Chain
- **Logic**: All transaction records are retrieved from World Mobile Chain transaction logs, including essential fields for fee calculation such as gas usage metrics, pricing parameters, and transaction metadata. Since World Mobile Chain lacks a native token address, the calculation uses Base chain's WMTX token address and symbol for fee token identification. Key transaction fields include gas usage amounts, gas prices, Layer 1 specific parameters, and block timestamps.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` for identification, `gas_used` and `l1_gas_used` for gas consumption, `gas_price` and `l1_gas_price` for pricing, `l1_fee_scalar` for Layer 1 fee adjustments, and `token_address` pointing to WMTX token

### Component B: Gas fee calculation  
- **Purpose**: Calculate both Layer 2 and Layer 1 gas fees for each transaction
- **Logic**: Two separate fee calculations are performed for each transaction. Layer 2 fees are calculated by multiplying the gas used by the gas price, then dividing by 1e18 to correct for token decimals. Layer 1 fees use a more complex calculation, multiplying Layer 1 gas used by Layer 1 gas price by a fee scalar, then dividing by 1e18 for decimal correction. Both fee components are calculated in the native WMTX token units.
- **Key fields**: `l2_gas_fee` calculated as gas usage times price, `l1_gas_fee` calculated using Layer 1 specific parameters and scalar adjustment

### Component C: Fee aggregation and processing
- **Purpose**: Combine fee components and prepare for currency conversion
- **Logic**: Layer 1 and Layer 2 gas fees are summed together to create total transaction fees. Any null values in either fee component are treated as zero to ensure accurate totals. Block timestamps are truncated to day boundaries for daily aggregation. The chain identifier is maintained for proper data classification.
- **Key fields**: `fees` representing total combined gas fees per transaction, `timestamp` truncated to daily grain

### Final aggregation
- **Combining components**: Total fees are aggregated by summing all transaction fees within each day period
- **Currency conversion**: WMTX token amounts are converted to USD using end-of-day price feeds, with decimal correction already applied during the gas fee calculation phase  
- **Time aggregation**: Daily boundaries are established by truncating timestamps to day level, with all transactions within a day contributing to that day's total
- **Final calculation**: The metric represents the sum of all USD-denominated transaction fees collected by the World Mobile Chain network each day, with gaps filled using zero values for days with no transaction activity and chain identification standardized to 'worldmobilechain'
