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 Active users (daily) Methodology

## 1. Overview

Daily Active Users (DAU) for Scroll measures the number of unique addresses that initiated at least one transaction on the Scroll blockchain within each calendar day. This metric provides insights into user engagement and adoption of the Scroll layer-2 scaling solution. The calculation uses a simple distinct count approach, where any address that sends a transaction during a given day is counted as an active user for that day.

## 2. Data sources

The calculation relies on the following raw data sources:
- **Scroll blockchain transaction records**: Complete transaction history from the Scroll layer-2 network, including sender addresses, timestamps, and transaction metadata
- **Transaction logs**: Raw blockchain data containing `from_address` (transaction sender), `block_timestamp` (when the transaction was included in a block), and `transaction_hash` (unique transaction identifier)

## 3. Step-by-step calculation

### Component A: User transaction data preparation
- **Purpose**: Extract and standardize user transaction data from raw Scroll blockchain records
- **Logic**: Raw Scroll transaction data is processed to identify transaction senders as users. Each transaction record provides a `from_address` field representing the user who initiated the transaction, along with the `block_timestamp` indicating when the transaction occurred. The data is classified with metadata including chain identification as 'scroll', user type as 'Transaction sender', market sector as 'blockchains_l2', and business segment as 'blockchain'
- **Key fields**: `block_timestamp` (transaction timing), `from_address` (user identifier), `transaction_hash` (unique transaction reference), `chain` (set to 'scroll'), `user_type` (set to 'Transaction sender')

### Component B: Daily user aggregation
- **Purpose**: Calculate distinct active users for each calendar day
- **Logic**: Transaction timestamps are truncated to day-level granularity using daily boundary logic. A distinct count operation is applied across the combination of truncated timestamp, chain, user type, and user address to ensure each unique address is counted only once per day, regardless of how many transactions they sent
- **Key fields**: `timestamp` (truncated to day), `user_address` (deduplicated user identifier), `timestamp_grain` (set to 'day'), metadata fields for classification

### Final aggregation
- **Combining components**: The processed transaction data flows directly into the daily aggregation step, where user addresses are deduplicated within each day
- **Currency conversion**: Not applicable for this user count metric
- **Time aggregation**: Daily boundaries are determined by truncating block timestamps to calendar day level, ensuring users are counted consistently within 24-hour periods
- **Final calculation**: The final DAU value represents the distinct count of user addresses that initiated at least one transaction within each calendar day on the Scroll blockchain. Incremental processing ensures efficient updates by only reprocessing recent data based on configurable lookback periods.
