# peaq Fees Methodology

## 1. Overview

The Peaq fees metric measures the total transaction fees collected by the Peaq network on a daily basis, expressed in USD. This metric tracks the revenue generated by the Peaq blockchain from transaction processing fees, providing insight into network usage and economic activity. The calculation extracts fee distribution events from Peaq's substrate-based blockchain, aggregates them daily, and converts native PEAQ token amounts to USD using end-of-day price feeds.

## 2. Data sources

- **Peaq blockchain events**: Parsed `TransactionFeesDistributed` events from the `blockReward` pallet on the Peaq substrate-based blockchain, containing base fee amounts distributed for transaction processing
- **Token price feeds**: End-of-day PEAQ token price data from CoinGecko for USD conversion
- **Blockchain metadata**: Transaction and block information including timestamps, block numbers, and extrinsic hashes for event tracking and incremental processing

## 3. Step-by-step calculation

### Component A: Raw fee data extraction
- **Purpose**: Extract and parse transaction fee amounts from Peaq blockchain events
- **Logic**: Filter Peaq blockchain event logs for `TransactionFeesDistributed` events from the `blockReward` pallet. These events contain fee distribution information in JSON format within the `event_data` field. Parse the base fee amount from the first element of the event data array. Convert the amount from native token units (18 decimals, represented as 1e18) to decimal format by dividing by the decimal factor. Include metadata such as `block_timestamp`, `block_number`, `extrinsic_hash`, `event_index`, and `chain` for tracking and processing.
- **Key fields**: `block_timestamp` for time-based aggregation, `amount` representing the base fee in decimal PEAQ tokens, `event_data` JSON array containing raw fee amounts, `event_method` and `event_pallet` for event filtering

### Component B: Daily aggregation
- **Purpose**: Aggregate all transaction fees by day to create daily fee totals
- **Logic**: Group all extracted fee records by day using timestamp truncation to day boundaries. Sum all individual fee amounts within each day to calculate total daily fees. Set consistent metadata fields including `timestamp_grain` as 'day', `product_id` and `chain_id` as 'peaq' for downstream processing.
- **Key fields**: `timestamp` truncated to day level, `amount` as the sum of all fees for that day

### Component C: USD conversion
- **Purpose**: Convert daily PEAQ token fee amounts to USD values
- **Logic**: Retrieve end-of-day PEAQ token prices from CoinGecko price feeds using the calculate prices macro. Join the aggregated daily fee data with price data by matching timestamps. Multiply the daily fee amount in PEAQ tokens by the corresponding end-of-day USD price to get the fee value in USD. Cast the result as a high-precision numeric type to maintain accuracy.
- **Key fields**: `fees` representing the final USD value of daily transaction fees, `timestamp` for joining fee and price data

### Final aggregation
- **Combining components**: The fee extraction, daily aggregation, and USD conversion steps are executed sequentially, with each step building upon the previous results
- **Currency conversion**: Native PEAQ token amounts are converted to USD using end-of-day prices from CoinGecko, applied at the daily aggregation level
- **Time aggregation**: All fees within each calendar day are summed together, with day boundaries determined by truncating timestamps to day precision
- **Final calculation**: The final metric represents the total USD value of all transaction fees collected by the Peaq network each day, calculated as the sum of individual base fees converted from native PEAQ tokens to USD using end-of-day exchange rates
