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 Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute transactions and interact with applications on the Sui blockchain. The economic cost of network usage is captured by this metric, comprising computational execution costs and the non-refundable portion of storage fees. Per standard accounting principles (ASC 606 / IFRS 15), refundable storage deposits are excluded from this metric as they are classified as liabilities rather than protocol revenue. These fees are paid in the network's native asset and are considered the total revenue generated by the protocol's primary service of processing transactions.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Transaction fee extraction

- **Purpose**: Capture the non-refundable computation and storage costs for every transaction processed on the network.
- **Logic**: Individual transaction records are parsed from the Sui blockchain. For each transaction, the `computation_cost` is extracted and added to 1% of the `storage_cost`. This 1% allocation is classified as the non-refundable protocol fee, while the remaining 99% of storage costs are excluded as they are rebatable when objects are deleted. Storage rebates are also excluded to ensure alignment with accounting standards (ASC 606 / IFRS 15) regarding refundable deposits. Failed transactions are included in this calculation as network resources are still consumed and gas fees are incurred. Historical data is captured starting from the network genesis on May 3, 2023.
- **Key fields**: `computation_cost`, `storage_cost`, `block_timestamp`, `digest`

### Component B: Asset normalization

- **Purpose**: Convert fee values from the native MIST denomination to SUI.
- **Logic**: Transaction fees are natively recorded in MIST, where $10^9$ MIST equals 1 SUI. Amounts are normalized by decimal precision using a divisor of 1,000,000,000 to express all values in the standard SUI asset denomination.
- **Key fields**: `gas_used`

### Component C: USD conversion and daily aggregation

- **Purpose**: Normalize fee values to USD and aggregate by day for cross-chain comparison.
- **Logic**: Normalized SUI fees are aggregated by day using UTC boundaries. These daily totals are multiplied by the end-of-day price feeds for the SUI asset. Final values are processed to ensure schema consistency and zero-filled for any days where transaction activity may not be present in the source data.
- **Key fields**: `fee_amount`, `price_usd`, `timestamp`
