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

Sui is a smart contract platform for decentralized applications (a blockchain). Sui was founded by Evan Cheng, Sam Blackshear, Adeniyi Abiodun, George Danezis and launched in 2022.

Sui (Mysten Labs) team & investors own and govern the protocol. They currently don’t take a cut of the total transaction fees paid by users (revenue). Sui's investors include a16z, Coinbase Ventures, Electric Capital, etc.

# Sui Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average fee users pay per transaction on Sui. This metric reflects the typical cost of interacting with the network and serves as a primary indicator of network affordability and resource demand. Fees on Sui are determined by computation and non-refundable storage costs and are paid in the native SUI asset.

## 2. Data sources

- **Blockchain events**: Transaction data from the Sui network, covering Sui
- **External data**: End-of-day price feeds for the native SUI asset

## 3. Step-by-step calculation

### Component A: Individual transaction fee extraction

- **Purpose**: Identify the non-refundable gas cost for every transaction processed on the network
- **Logic**: Transaction data is parsed to extract `computation_cost` and `storage_cost` from each transaction record. The non-refundable protocol fee is calculated in MIST (the native subunit of SUI) as the sum of the computation cost and 1% of the storage cost. The remaining 99% of storage costs are excluded from the fee calculation as they are rebatable when objects are deleted. All transactions, including those that failed, are included in this extraction as they still incur gas costs on the network.
- **Key fields**: `computation_cost` (MIST), `storage_cost` (MIST), `digest` (transaction identifier)

### Component B: Daily fee aggregation and USD conversion

- **Purpose**: Calculate the total volume of fees paid daily in a standardized currency
- **Logic**: Individual transaction fees are normalized by decimal precision to convert values from MIST to SUI. These values are then aggregated to determine the total fees paid per day. The resulting daily totals are multiplied by end-of-day price feeds to convert the volume into USD.
- **Key fields**: `gas_used`, `block_timestamp` (timing)

### Component C: Transaction count aggregation

- **Purpose**: Determine the total number of transactions processed per day
- **Logic**: The total count of unique transaction digests is calculated for each daily interval. This count includes all successfully executed transactions as well as failed transactions that were processed by the network validators.
- **Key fields**: `digest` (transaction hash)

### Component D: Average fee calculation

- **Purpose**: Derive the final average fee metric
- **Logic**: The total daily fee volume in USD is divided by the total daily transaction count. This calculation is performed at daily granularity using UTC day boundaries to produce the final average transaction fee.
- **Key fields**: `fees` (total daily USD fees), `transaction_count` (total daily transactions)
