# X Layer Average transaction fee Methodology

## 1. Overview

Average transaction fee is defined as the average fee paid per transaction on X Layer. It is used to reflect how much it typically costs to execute transactions on the network. This metric is calculated by dividing the total transaction fees collected by the total number of transactions executed over a given period. It is utilized as a key indicator of network affordability and economic throughput.

## 2. Data sources

- **Blockchain events**: Transaction records including gas usage, gas prices, and L1 fee parameters, covering X Layer
- **External data**: End-of-day price feeds for the native gas asset (OKB)

## 3. Step-by-step calculation

### Component A: Transaction count aggregation

- **Purpose**: Calculate the total number of transactions executed on X Layer
- **Logic**: Transaction records are aggregated daily. The total transaction count is determined by counting the unique transaction hashes recorded on X Layer for each day
- **Key fields**: `transaction_hash`, `block_timestamp`

### Component B: Gas fee extraction and calculation

- **Purpose**: Calculate the total gas fees paid on X Layer, accounting for both L2 execution and L1 data fees
- **Logic**: Gas fees are calculated by summing the L2 execution fees and the L1 data fees. The L2 execution fee is calculated by multiplying the gas used by the gas price. The L1 data fee is determined by either using the direct L1 fee field or calculating it using L1 gas used, L1 gas price, and the L1 fee scalar. These components are normalized by decimal precision and summed to represent the total daily fees in the native gas asset (OKB)
- **Key fields**: `gas_used`, `gas_price`, `l1_fee`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`

### Component C: USD conversion

- **Purpose**: Convert the total daily gas fees from the native gas asset to USD
- **Logic**: The daily gas fees denominated in OKB are multiplied by the end-of-day price feeds for OKB to determine the total daily fees in USD
- **Key fields**: `fees`, `price_usd`

### Component D: Average transaction fee calculation

- **Purpose**: Determine the average fee paid per transaction
- **Logic**: The total daily gas fees in USD are divided by the total daily transaction count. This division is performed to yield the average transaction fee for X Layer on a daily basis
- **Key fields**: `fees`, `transaction_count`
