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 Transaction count Methodology

## 1. Overview

The Scroll transaction count metric measures the daily number of unique transactions on the Scroll Layer 2 blockchain, segmented by destination address. This metric provides insights into network activity and usage patterns by tracking distinct transactions executed each day. The calculation aggregates raw blockchain transaction data into daily counts, ensuring complete time series data with proper gap filling.

## 2. Data sources

The metric relies on the following raw data sources:
- **Scroll blockchain transaction records**: Raw transaction data from the Scroll Layer 2 network including transaction hashes, timestamps, sender and recipient addresses, gas usage, and fee information
- **Token metadata**: Standardized token information including the native ETH token address and symbol for Scroll
- **Chain configuration data**: Blockchain metadata including chain identifiers, market sector classifications, and business segment mappings

## 3. Step-by-step calculation

### Component A: Transaction data standardization
- **Purpose**: Standardize raw Scroll transaction data with proper data types and metadata
- **Logic**: Raw transaction records from the Scroll blockchain are processed to ensure consistent data types. The `block_timestamp` field is cast as a timestamp, transaction and address fields are standardized as strings, and gas-related fields are cast as big numeric values. Additional metadata is added including the native ETH token address (`0x5300000000000000000000000000000000000004`), token symbol (`ETH`), and chain identifier (`scroll`)
- **Key fields**: `block_timestamp`, `transaction_hash`, `from_address`, `to_address`, `gas_used`, `l1_fee`, `gas_price`

### Component B: Daily transaction aggregation
- **Purpose**: Aggregate transaction counts by day and destination address
- **Logic**: Standardized transaction data is grouped by truncating timestamps to day boundaries using `timestamp_trunc` function. For each day and destination address (`to_address`), the distinct count of `transaction_hash` values is calculated to avoid double-counting duplicate entries. Additional categorical metadata is assigned including chain identifier (`scroll`), market sector (`blockchains_l2`), business segment (`blockchain`), with product and contract name fields set to null
- **Key fields**: `timestamp` (truncated to day), `transaction_count` (distinct count), `to_address`, `chain_id`, `market_sector_id`, `business_segment_id`

### Final aggregation
- **Combining components**: The daily aggregated data is processed through the `finalize_metric_transaction_count` macro which validates the data schema, ensures proper field naming and types, and implements gap-filling logic
- **Time aggregation**: Data is aggregated to daily boundaries with complete time series coverage
- **Gap filling**: Missing days in the time series are filled with zero transaction counts using the `fill_zeros` strategy to ensure no data gaps exist
- **Final calculation**: The final metric represents the distinct count of transaction hashes per day per destination address on the Scroll network, with additional filtering applied based on chain availability rules
