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 Average fees per user (AFPU) Methodology

## 1. Overview

Average Fees Per User (AFPU) measures the average amount of transaction fees paid per daily active user on the Aptos blockchain. This metric provides insights into user engagement economics and fee monetization efficiency by calculating the ratio of total daily fees in USD to the number of unique daily active users. The calculation uses transaction gas fees converted to USD and divides by the count of unique transaction sender addresses per day.

## 2. Data sources

The AFPU calculation relies on three primary data sources:

- **Aptos blockchain transaction records**: Complete transaction data including sender addresses, gas consumption (`gas_used`), and gas unit prices (`gas_unit_price`) for all transactions on the Aptos network
- **APT token price feeds**: End-of-day APT-USD price data from two sources - Chainlink price feeds (from August 10, 2023 onwards) for real-time accuracy, and CoinGecko daily market data for historical prices prior to August 10, 2023
- **Genesis transaction handling**: Special handling for pre-genesis transactions with timestamps reassigned to the Aptos mainnet launch date of October 12, 2022

## 3. Step-by-step calculation

### Component A: Daily fee calculation

- **Purpose**: Calculates the total transaction fees paid in USD for each day
- **Logic**: Extracts all Aptos transactions and processes gas fee data. The `gas_unit_price` field is converted from the smallest APT denomination by dividing by 10^8 to get the standard APT unit price. Daily fees are calculated by multiplying `gas_used` by the converted `gas_unit_price` for each transaction, then summing all fees per day. Genesis transactions with timestamps before January 1, 2000 are reassigned to October 12, 2022 to represent the Aptos mainnet launch date. The daily APT fee amounts are then converted to USD by joining with end-of-day APT price data.
- **Key fields**: `gas_used` (gas consumed per transaction), `gas_unit_price` (price per gas unit in smallest APT units), `block_timestamp` (transaction timestamp), `fee_amount` (calculated daily fee total in APT)

### Component B: Daily active user count

- **Purpose**: Counts the number of unique users (sender addresses) active each day
- **Logic**: Identifies unique daily active users by extracting distinct `sender` addresses from all Aptos transactions, with timestamps truncated to daily boundaries. Users are classified as 'Transaction sender' type since they represent any address that initiated a transaction. The counting uses HyperLogLog (HLL) probabilistic counting algorithm with 15-bit precision to efficiently handle large-scale distinct counting while maintaining accuracy. The HLL approach aggregates user counts across multiple dimensions including project level, chain level, user type, and product type breakdowns.
- **Key fields**: `sender` (transaction initiator address), `block_timestamp` (truncated to day), `user_dau` (unique user identifier), `user_type` (classification as 'Transaction sender')

### Final aggregation

- **Combining components**: Daily fee totals in USD are divided by daily active user counts using the `calculate_arpu` macro, which performs the mathematical division of revenue (fees) by users
- **Currency conversion**: APT fees are converted to USD by multiplying daily APT fee amounts with corresponding end-of-day APT-USD prices from either Chainlink (August 10, 2023 onwards) or CoinGecko (prior dates)
- **Time aggregation**: All data is aggregated to daily boundaries using timestamp truncation to day level, ensuring consistent temporal alignment between fee and user data
- **Final calculation**: AFPU = Daily Total Fees (USD) ÷ Daily Active Users. Missing days are filled with zero values using the 'fill_zeros' strategy to maintain complete time series continuity. The final result represents the average amount of transaction fees in USD paid per unique daily active user on the Aptos network.
