# OKX Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute transactions on X Layer. This metric is used to quantify the economic value generated by the network, which includes both L2 execution fees and L1 data availability fees. All transaction fees are paid using the native gas asset, OKB, and are converted to USD. This metric is essential for assessing user demand and the overall economic activity on X Layer.

## 2. Data sources

- **Blockchain events**: Transaction execution data, including gas usage and gas price parameters, from transaction records, covering X Layer
- **External data**: End-of-day price feeds for the native gas asset (OKB)

## 3. Step-by-step calculation

### Component A: X Layer L2 execution fee calculation

- **Purpose**: Calculate the fees associated with executing transactions on the L2 network
- **Logic**: Gas used and gas price are extracted from transaction records. The L2 execution fee is calculated by multiplying the gas used by the gas price for each transaction. These values are aggregated daily and normalized by decimal precision to represent the total L2 execution fees in the native gas asset (OKB).
- **Key fields**: `gas_used`, `gas_price`

### Component B: X Layer L1 data fee calculation

- **Purpose**: Calculate the fees paid to post transaction data to the L1 security layer
- **Logic**: L1 fee metrics are extracted from transaction records. The L1 gas fee is determined by either utilizing the direct L1 fee field or, if unavailable, calculating it by multiplying the L1 gas used, L1 gas price, and the L1 fee scalar. These values are aggregated daily and normalized by decimal precision to represent the total L1 data fees in the native gas asset (OKB).
- **Key fields**: `l1_fee`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`

### Component C: USD conversion and aggregation

- **Purpose**: Combine L1 and L2 fee components and convert the total to USD
- **Logic**: The L2 execution fees and L1 data fees are summed to calculate the total daily transaction fees. The aggregated fees are then multiplied by the end-of-day price of the native gas asset (OKB) to convert the values into USD. Daily granularity is maintained using UTC day boundaries.
- **Key fields**: `fees`, `price_usd`
