Fraxtal batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

Fraxtal is an Ethereum Layer 2 (L2) blockchain built on the OP Stack by Frax Finance. It uses frxETH as the gas token and features a blockspace incentive system called Flox. Fraxtal launched in February 2024.

Frax Finance team owns and governs the protocol. Frax Finance's investors include Dragonfly Capital, Mechanism Capital, Galaxy Digital, etc.

# Fraxtal Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute transactions on Fraxtal. This metric captures the economic activity generated by users interacting with the network and includes both the costs of Layer 2 execution and the data availability costs associated with settling transaction data on Layer 1. Fees are paid in the network's native gas asset, which transitioned from frxETH to FRAX following the North Star hardfork.

## 2. Data sources

- **Blockchain events**: Transaction-level execution data from the Fraxtal network
- **External data**: End-of-day price feeds for native gas assets

## 3. Step-by-step calculation

### Component A: Transaction data extraction

- **Purpose**: Retrieve gas usage and fee parameters for all network transactions.
- **Logic**: Metadata is parsed from every transaction to extract `gas_used` for Layer 2 execution and the corresponding `gas_price`. For Layer 1 settlement costs, the `l1_gas_used`, `l1_gas_price`, and `l1_fee_scalar` are extracted. The native gas asset address is identified based on the transaction timestamp: transactions occurring before the North Star hardfork (April 29, 2025) are associated with wrapped frxETH, while transactions occurring after the hardfork are associated with wrapped FRAX.
- **Key fields**: `gas_used`, `gas_price`, `l1_gas_used`, `l1_gas_price`, and `l1_fee_scalar`

### Component B: Fee component calculation

- **Purpose**: Calculate the individual cost components for network usage.
- **Logic**: The Layer 2 execution fee is calculated by multiplying `gas_used` by the `gas_price`. The Layer 1 data fee is calculated by multiplying `l1_gas_used` by the `l1_gas_price` and the `l1_fee_scalar`. Both results are normalized by decimal precision.
- **Key fields**: `l2_gas_fee` and `l1_gas_fee`

### Component C: Aggregation and USD conversion

- **Purpose**: Totaling network-wide fees and normalizing values to USD.
- **Logic**: Total fees are calculated as the sum of the Layer 1 and Layer 2 fee components. These values are aggregated by day and converted to USD using end-of-day price feeds for the respective native gas asset active at the time of the transaction. Daily granularity is established using UTC day boundaries.
- **Key fields**: `fees` and `timestamp`
