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 Supply-side fees Methodology

## 1. Overview

Supply-side fees represent the portion of transaction fees that are paid to supply-side participants such as liquidity providers, validators, or other network participants who provide services to users. For the Aptos blockchain, this metric is consistently zero because Aptos does not have a fee-sharing mechanism that allocates transaction fees to supply-side participants. All transaction fees on Aptos go to validators and the network itself rather than being shared with external supply-side providers.

## 2. Data sources

The calculation relies on the following data sources to establish the metric structure:

- **Aptos blockchain transaction data**: Raw transaction records including gas usage, gas unit prices, sender addresses, transaction hashes, and block timestamps
- **Chainlink price feeds**: End-of-day APT token price data from Chainlink oracle feeds starting from August 10, 2023
- **CoinGecko price data**: Historical end-of-day APT token prices from CoinGecko for periods before Chainlink data became available
- **Transaction metadata**: Block timestamps and transaction identifiers for proper time-series aggregation

## 3. Step-by-step calculation

### Component A: Base metric structure derivation

- **Purpose**: Establish the proper time-series structure and metadata for the supply-side fees metric
- **Logic**: The calculation references the base Aptos fees metric to obtain the standardized timestamp, chain identifier, and product identifier fields. This ensures consistency with other Aptos metrics and provides the proper time-series framework. The base fees metric calculates total transaction fees by aggregating daily gas fees from Aptos transactions and converting them to USD using APT price data.
- **Key fields**: `timestamp` (daily timestamps), `chain_id` (set to 'aptos'), `product_id` (null for blockchain-level metrics), `timestamp_grain` (set to 'day')

### Component B: Supply-side fee allocation

- **Purpose**: Determine the portion of total fees that should be allocated to supply-side participants
- **Logic**: For Aptos, the supply-side fees are hardcoded to zero for all time periods and all transactions. This reflects the Aptos blockchain's fee structure, where transaction fees are paid by users for gas consumption but are not shared with supply-side participants like liquidity providers or other service providers. All fees collected go to validators and the network itself.
- **Key fields**: `fees_supply_side` (consistently set to 0)

### Final aggregation

- **Combining components**: The metric combines the time-series structure from the base fees metric with the zero-value supply-side fee allocation to create complete daily records
- **Currency conversion**: While the underlying fee calculation involves USD conversion using APT prices, the supply-side portion is zero regardless of currency
- **Time aggregation**: Daily boundary logic is maintained consistently with other Aptos metrics, using daily timestamps truncated to day granularity
- **Final calculation**: The final metric value is always zero USD for supply-side fees, reflecting that Aptos does not implement fee sharing with supply-side participants. The calculation ensures proper time-series completeness and data validation through the finalization macro while maintaining the zero-value allocation across all time periods.
