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 Fees Methodology

## 1. Overview

Fees are measured as the total value paid by users to execute transactions on Sei Network. This metric captures the economic value generated by the blockchain through transaction processing and resource allocation. Fees are currently captured for Sei EVM and are denominated in the native SEI asset.

## 2. Data sources

- **Blockchain events**: Transaction receipts covering Sei EVM
- **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**: Identify individual transaction costs on the network.
- **Logic**: Transaction receipts are parsed to extract the `gas_used` and the `gas_price` (effective gas price) for every successful transaction. The native SEI asset is identified as the underlying currency for these payments.
- **Key fields**: `receipt_gas_used`, `receipt_effective_gas_price`, and `token_address`

### Component B: Gas fee aggregation

- **Purpose**: Aggregate transaction costs into daily totals.
- **Logic**: For each transaction, the total gas fee is calculated by multiplying the gas used by the effective gas price. These individual transaction fees are summed per day to provide a total daily fee volume at the chain level.
- **Key fields**: `gas_used` and `gas_price`

### Component C: USD conversion and normalization

- **Purpose**: Standardize fee values into USD for reporting.
- **Logic**: Aggregated fee amounts are normalized by decimal precision to account for the native asset's decimals. These normalized values are then multiplied by end-of-day price feeds for the SEI asset. Daily granularity is maintained using UTC day boundaries.
- **Key fields**: `l1_gas_fee`, `timestamp`, and `price_usd`
