# Circle Median transaction fee Methodology

## 1. Overview

Median transaction fee measures the median fee paid across all transactions on Arc. The typical cost paid by a user is represented by this metric, which is not skewed by extreme outlier values. Because gas fees on Arc are paid in USD Coin, transaction fees are natively denominated in USD, and direct cost analysis is enabled without external price conversions.

## 2. Data sources

- **Blockchain events**: Transaction data covering Arc

## 3. Step-by-step calculation

### Component A: Transaction fee extraction

- **Purpose**: Extract gas usage and gas price for each transaction on Arc
- **Logic**: Transaction records are parsed from Arc. For each transaction, the gas used is multiplied by the effective gas price to determine the raw transaction fee. Since gas prices are scaled, the raw fee is normalized by decimal precision to convert the value into USD Coin.
- **Key fields**: `gas_used`, `gas_price`

### Component B: Median fee calculation

- **Purpose**: Determine the median transaction fee for each day
- **Logic**: Transaction fees are grouped by day using UTC boundaries. The median transaction fee is calculated for each daily interval to ensure the typical cost paid by a user is represented.
- **Key fields**: `block_timestamp`, `fee_amount`
