# World Mobile Chain Average revenue per user (ARPU) Methodology

## 1. Overview

Average Revenue Per User (ARPU) for World Mobile Chain measures the average daily revenue generated per active telecom service subscriber. This metric is calculated by dividing daily revenue (from on-chain transaction fees) by the count of daily active users (identified through telecom service contract interactions). ARPU helps evaluate the monetization efficiency and user engagement value of World Mobile's decentralized telecom network.

## 2. Data sources

- **World Mobile Chain transaction records**: Complete transaction data including gas usage, gas prices, and L1/L2 fee components
- **World Mobile Chain event logs**: Parsed ERC20 `Transfer` events from World Mobile's telecom service contract
- **End-of-day price feeds**: Token price data for USD conversion of fee revenue
- **Base chain token metadata**: WMTX token information used for fee calculations (World Mobile uses Base chain's WMTX token)

## 3. Step-by-step calculation

### Component A: Revenue calculation
- **Purpose**: Calculate daily revenue from World Mobile Chain transaction fees
- **Logic**: Transaction records are processed to extract gas fees paid by users. Both L2 gas fees (calculated as `gas_used` × `gas_price` ÷ 1e18) and L1 gas fees (calculated as `l1_gas_used` × `l1_gas_price` × `l1_fee_scalar` ÷ 1e18) are computed and summed together. These fees represent revenue collected by World Mobile from on-chain transactions, not including off-chain service fees. Fee amounts are converted from wei to ETH units by dividing by 1e18, then converted to USD using end-of-day price feeds. The chain identifier is recast from 'base' to 'worldmobilechain' for consistency. Daily revenue is aggregated by truncating timestamps to day boundaries.
- **Key fields**: `gas_used`, `gas_price`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`, `block_timestamp`, `token_address`

### Component B: Daily active users calculation  
- **Purpose**: Count distinct users actively engaging with World Mobile's telecom services each day
- **Logic**: ERC20 `Transfer` events are filtered to include only those from World Mobile's telecom service contract address `0xd7d10d554fb33a37a7720e5666590205dbf5f482`. The `to_address` field from these transfer events identifies active telecom service subscribers. Users are classified with the type 'Telecom service active subscriber'. Daily distinct users are calculated by truncating event timestamps to day boundaries and counting unique user addresses using HyperLogLog aggregation for efficiency. The aggregation creates multiple dimensional breakdowns including project-level, chain-level, user-type-level, and product-level views.
- **Key fields**: `block_timestamp`, `to_address` (as `user_address`), contract `address`, `user_type`

### Final aggregation
- **Combining components**: The ARPU calculation uses a dedicated macro that divides the daily revenue metric by the daily active users metric for matching timestamps
- **Currency conversion**: Revenue amounts are converted to USD using end-of-day token price feeds applied to the calculated fee amounts
- **Time aggregation**: Both revenue and user metrics are aggregated to daily boundaries using timestamp truncation, ensuring alignment for division
- **Final calculation**: ARPU = Daily Revenue (USD) ÷ Daily Active Users. Missing days in either metric are filled with zeros before the division to maintain data continuity and prevent calculation errors
