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.

# Sei Network Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average fee users pay per transaction on Sei Network. This metric reflects the typical cost of interacting with the network, specifically within the Sei EVM environment. It is calculated by dividing the total daily transaction fees by the total number of unique transactions processed.

## 2. Data sources

- **Blockchain events**: Transaction records from Sei EVM, covering Sei Network
- **External data**: End-of-day price feeds for the native SEI asset

## 3. Step-by-step calculation

### Component A: Sei EVM transaction data extraction

- **Purpose**: Capture gas usage and pricing data for all on-chain transactions
- **Logic**: Gas used and effective gas price values are retrieved for every transaction recorded on Sei EVM. The total fee for an individual transaction is calculated by multiplying the gas used by the effective gas price.
- **Key fields**: `receipt_gas_used`, `receipt_effective_gas_price`

### Component B: Sei EVM transaction count aggregation

- **Purpose**: Determine the total volume of transactions processed daily
- **Logic**: Unique transaction hashes are aggregated on a daily basis. This count is filtered to include only transactions occurring within the Sei EVM product.
- **Key fields**: `transaction_hash`

### Component C: Fee summation and USD conversion

- **Purpose**: Normalize total daily fee volume into a standardized currency
- **Logic**: Individual transaction fees are summed to calculate a total daily fee volume. These amounts are normalized by decimal precision and converted to USD using end-of-day price feeds for the native SEI asset.
- **Key fields**: `block_timestamp`, `token_address`

### Component D: Average transaction fee derivation

- **Purpose**: Calculate the final mean fee per transaction
- **Logic**: The total daily transaction fees in USD are divided by the total daily transaction count. A safe division is applied to ensure the metric is calculated correctly even during periods of low activity. This result is aggregated with daily granularity using UTC day boundaries.
