# IoTeX Fees Methodology

## 1. Overview

The IoTeX fees metric measures the total daily gas fees paid by users on the IoTeX blockchain, converted to USD. This metric represents the cost users pay for transaction processing and smart contract execution on the IoTeX network. The calculation handles both legacy gas pricing (pre-EIP-1559) and modern effective gas pricing mechanisms, including blob gas fees for data availability.

## 2. Data sources

- **IoTeX transaction records**: Raw blockchain transaction data including gas usage, gas prices, transaction hashes, block information, and participant addresses
- **End-of-day token price feeds**: USD exchange rates for the native IOTX token used for currency conversion
- **IoTeX native token metadata**: Token decimal and contract information for the native IOTX token

## 3. Step-by-step calculation

### Component A: Transaction data processing
- **Purpose**: Extracts and processes raw IoTeX transaction data with gas fee calculations
- **Logic**: Retrieves all IoTeX blockchain transactions and processes gas-related fields. For blocks before the Vanuatu upgrade (block 33730921), uses the original `gas_price` field. For blocks after Vanuatu, uses the `receipt_effective_gas_price` field to reflect EIP-1559 pricing. Converts all gas prices from wei to IOTX by dividing by 10^18. Also processes blob gas information (`receipt_blob_gas_used` and `receipt_blob_gas_price`) for data availability fees. Normalizes addresses to lowercase format.
- **Key fields**: `block_timestamp` for daily grouping, `gas_used` for transaction gas consumption, `effective_gas_price` for cost per gas unit, `blob_gas_used` and `blob_gas_price` for blob data fees, `from_address` and `to_address` for transaction participants

### Component B: Fee calculation and daily aggregation  
- **Purpose**: Calculates individual transaction fees and aggregates them by day
- **Logic**: For each transaction, multiplies `gas_used` by `effective_gas_price` to get the base transaction fee. Adds blob gas fees by multiplying `blob_gas_used` by `blob_gas_price` when present (defaults to zero if null). Sums all transaction fees within each calendar day using daily timestamp truncation to establish time boundaries.
- **Key fields**: `fee_amount` as the calculated per-transaction fee, `timestamp` as the daily aggregation boundary, `fees` as the daily total

### Final aggregation
- **Combining components**: Daily fee totals from the aggregation component are passed through for USD conversion and standardization
- **Currency conversion**: Native IOTX fee amounts are converted to USD using end-of-day price feeds through the convert_to_usd_and_correct_decimals macro
- **Time aggregation**: Data is aggregated to daily granularity using calendar day boundaries (timestamp truncated to day)
- **Final calculation**: The final metric represents the sum of all gas fees (regular transaction fees plus blob gas fees) paid on the IoTeX blockchain per day, converted to USD, with zero-filling applied for days with no activity and chain availability filters for data quality assurance
