# Robinhood Chain Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute transactions on Robinhood Chain. The cost of block space and computational resources consumed during transaction execution is represented by these fees. The collected fees are denominated in Wrapped Ether (WETH), which serves as the native gas asset for the network. This metric is critical for evaluating the economic activity and user demand for transaction processing on Robinhood Chain.

## 2. Data sources

- **Blockchain events**: Transaction execution data from the `transactions` table, covering Robinhood Chain
- **External data**: End-of-day price feeds for Wrapped Ether (WETH)

## 3. Step-by-step calculation

### Component A: Gas fee extraction

- **Purpose**: Extract gas consumption and gas price for each transaction on Robinhood Chain
- **Logic**: Transaction records are parsed from the `transactions` table. For each transaction, the gas used and the effective gas price are extracted. The total gas fee per transaction is calculated by multiplying the gas used by the effective gas price. The gas fee is denominated in Wrapped Ether (WETH), which is the native gas asset of the chain.
- **Key fields**: `gas_used` (gas consumed), `gas_price` (gas price per unit)

### Component B: Daily aggregation and normalization

- **Purpose**: Aggregate transaction fees to a daily granularity and normalize the asset amounts
- **Logic**: Transaction-level gas fees are aggregated by truncating the block timestamps to UTC day boundaries. The aggregated gas fees are normalized by the decimal precision of the native asset (WETH) to convert the raw values into standard asset units.
- **Key fields**: `block_timestamp` (timing), `gas_used` (gas consumed), `gas_price` (gas price per unit)

### Component C: USD conversion and finalization

- **Purpose**: Convert the normalized daily fees into USD and apply final metric formatting
- **Logic**: The normalized daily gas fees are multiplied by the end-of-day USD price of Wrapped Ether (WETH) to determine the daily fee value in USD. A zero-filling strategy is applied to ensure continuous daily data coverage, and a chain availability filter is applied to align the output with active data windows.
- **Key fields**: `timestamp` (daily date), `l2_gas_fee` (normalized fee amount), `price_usd` (asset price)
