Validators process transactions and receive fees from users (supply-side fees).

Aptos is a smart contract platform for decentralized applications (a blockchain). Aptos was founded by Mo Shaikh and Avery Ching and launched in 2022.

APT token holders own and govern the protocol. They currently don’t take a cut of the total transaction fees paid by users (revenue). Aptos’ investors include Binance Labs, Jump Crypto, Apollo, etc.

# Aptos Fees Methodology

## 1. Overview

This metric calculates the total daily transaction fees paid on the Aptos blockchain, expressed in USD. It measures the aggregate cost users pay to execute transactions on the network, providing insight into network usage and economic activity. The calculation multiplies gas consumption by gas prices for all transactions, then converts the results from native APT tokens to USD using market prices.

## 2. Data sources

- **Aptos transaction data**: Raw blockchain transaction records containing gas usage metrics, unit prices, sender information, and timestamps
- **Chainlink price feeds**: End-of-day APT token price data from August 10, 2023 onwards, sourced from Chainlink oracles
- **CoinGecko market data**: Historical end-of-day APT token prices for periods before Chainlink data availability (pre-August 2023)

## 3. Step-by-step calculation

### Component A: Transaction processing
- **Purpose**: Extract and normalize gas fee data from raw Aptos transactions
- **Logic**: Process all Aptos transactions by extracting the `gas_used` and `gas_unit_price` fields. Convert gas unit prices from their native 8-decimal format by dividing by 10^8 to get the actual APT price per unit of gas. Handle edge cases where transactions have invalid timestamps (before 2000-01-01) by reassigning them to the Aptos genesis date of October 12, 2022. This ensures all historical transactions are properly dated and included in calculations.
- **Key fields**: `gas_used` (gas consumption per transaction), `gas_unit_price` (price per gas unit in 8-decimal format), `block_timestamp` (transaction timing), `transaction_hash` (unique identifier), `sender` (transaction originator)

### Component B: Daily fee aggregation  
- **Purpose**: Calculate total gas fees paid per day in native APT tokens
- **Logic**: Group all processed transactions by calendar day using timestamp truncation to daily boundaries. For each day, calculate the fee amount for individual transactions by multiplying `gas_used` by the normalized `gas_unit_price`. Sum these individual transaction fees across all transactions within each day to get the total daily fee amount in APT tokens.
- **Key fields**: `timestamp` (daily boundary), `fee_amount` (aggregated daily fees in APT), `timestamp_grain` (set to 'day' for daily aggregation)

### Component C: Price data compilation
- **Purpose**: Create complete historical APT price series combining multiple data sources
- **Logic**: Merge APT token prices from two sources based on data availability. Use Chainlink oracle prices for dates from August 10, 2023 onwards, as this provides more reliable and frequent price updates. For historical periods before August 10, 2023, use CoinGecko daily market data to fill the gap. This creates a continuous price series covering the entire operational history of the Aptos network.
- **Key fields**: `timestamp` (daily price date), `price` (APT price in USD)

### Final aggregation
- **Combining components**: Join the daily fee amounts with corresponding APT prices by matching on the daily timestamp. This links each day's fee total with the appropriate market price for conversion.
- **Currency conversion**: Multiply the daily `fee_amount` (in APT) by the matching `price` (USD per APT) to convert native token fees into USD values
- **Time aggregation**: Maintain daily granularity with each record representing fees for a complete calendar day
- **Final calculation**: The final metric value equals the sum of (gas_used × gas_unit_price) for all transactions in a day, multiplied by the APT-to-USD exchange rate for that day. Missing days are filled with zero values to maintain complete time series continuity.
