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

Scroll is an L2 smart contract platform for decentralized applications on Ethereum. Scroll was founded by Sandy Peng, Haichen Shen, and Ye Zhang and launched in 2023.

SCR tokenholders own and govern the protocol. Scroll's investors include Polychain, Qiming Venture Partners, etc.

# Scroll Average revenue per user (ARPU) Methodology

## 1. Overview

Average revenue per user (ARPU) measures the average amount of revenue generated by each active user on Scroll within a 24-hour window. This metric is used to evaluate the protocol's ability to monetize its user base and to understand the economic value contributed by individual participants on a daily basis. For Scroll, revenue is derived from the total transaction fees paid by users, which include both L2 execution costs and the costs associated with posting data to Ethereum.

## 2. Data sources

- **Revenue**: Derived from the Revenue metric
- **Active users (daily)**: Derived from the Active users (daily) metric
- **Blockchain data**: Transaction-level execution and resource usage data covering Scroll
- **External data**: End-of-day price feeds for native gas assets

## 3. Step-by-step calculation

### Component A: Daily active user tracking

- **Purpose**: Identify and count the number of unique participants interacting with the network
- **Logic**: Unique transaction signers are extracted from the sender field of all processed transactions. These addresses are aggregated on a daily basis to determine the total count of active users (daily). Duplicate addresses within the same UTC day are excluded to ensure an accurate count of unique participants.

### Component B: Revenue calculation

- **Purpose**: Determine the total protocol revenue generated from transaction activity
- **Logic**: Revenue is calculated as the sum of all transaction fees paid to the network. For every transaction, the L2 gas fee is calculated by multiplying the gas used by the effective gas price. The L1 fee, representing the cost of data availability on Ethereum, is added to the L2 fee to arrive at the total fee per transaction. These values are normalized by decimal precision, converted to USD using end-of-day price feeds for the native asset, and aggregated daily. All collected fees are classified as protocol revenue.

### Component C: Average revenue calculation

- **Purpose**: Calculate the final ARPU metric by combining revenue and user data
- **Logic**: Total daily revenue is divided by the total number of active users (daily) for the corresponding 24-hour period. This calculation is performed at a daily granularity with UTC day boundaries. If no activity is recorded for a specific day, the value is set to zero.
