# Sei EVM Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average cost paid by users for each transaction processed on Sei EVM. This metric is utilized to reflect the typical expense associated with interacting with the network. Fees are captured from native gas consumption, converted to USD using end-of-day price feeds, and averaged across the total number of successful transactions within a specific timeframe.

## 2. Data sources

- **Blockchain events**: transaction execution data including gas consumption and price records from Sei EVM
- **External data**: end-of-day price feeds for the native SEI asset

## 3. Step-by-step calculation

### Component A: Sei EVM transaction fee extraction

- **Purpose**: To identify and quantify the total gas fees paid for transaction execution on Sei EVM.
- **Logic**: Gas fees are calculated for each transaction by multiplying the `gas_used` by the `gas_price`. These values are extracted from the transaction receipt data on Sei EVM. All amounts are normalized by decimal precision to convert the values into native SEI units.
- **Key fields**: `gas_used`, `gas_price`, and `block_timestamp`.

### Component B: Sei EVM transaction volume tracking

- **Purpose**: To determine the total number of transactions processed by the network for the calculation of the mean fee.
- **Logic**: The total volume of network activity is determined by counting distinct `transaction_hash` entries from the Sei EVM transaction records. This count is aggregated daily to serve as the denominator for the average fee calculation.
- **Key fields**: `transaction_hash` and `block_timestamp`.

### Component C: USD conversion and final averaging

- **Purpose**: To normalize fee data to USD and calculate the final average per transaction.
- **Logic**: Daily total gas fees are multiplied by the end-of-day USD price of the native SEI asset. The average transaction fee is then calculated by dividing the total daily fees in USD by the total daily transaction count. A safety division is applied to handle instances with zero transactions, and the final values are aligned to UTC day boundaries.
- **Key fields**: `fees` (in USD) and `transaction_count`.

Blockchains (L1)

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

Sei is a Layer 1 blockchain built for fast, low-cost financial transactions. It combines the security and reliability of Ethereum with the high performance of Solana. To date, Sei has processed billions of transactions across more than 90 million wallets. The project is backed by leading investors, including Multicoin Capital, Jump, Coinbase Ventures, and Circle Ventures. Token Terminal exclusively tracks Sei EVM data.

SEI holders own and govern the protocol. They currently do not take a cut of the transaction fees paid by users (revenue). Sei's investors include Multicoin Capital, Coinbase, etc.
