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 Revenue Methodology

## 1. Overview

Scroll revenue represents the total gas fees collected by the Scroll Layer 2 network on a daily basis. This metric measures the USD value of all transaction fees paid by users, which includes both Layer 2 execution fees and Layer 1 data availability fees. Since Scroll operates as a zkEVM rollup that collects gas fees as its primary revenue source, revenue is calculated as the sum of all gas fees collected from network users.

## 2. Data sources

- **Scroll transaction records**: Raw blockchain transaction data including gas usage, gas prices, effective gas prices, and L1 fees from the Scroll network
- **End-of-day token price feeds**: ETH price data used to convert gas fees from ETH to USD values  
- **Token metadata**: ETH token information including symbol and decimal specifications

## 3. Step-by-step calculation

### Component A: Transaction data processing
- **Purpose**: Extract and standardize relevant transaction details from raw Scroll blockchain data
- **Logic**: Raw Scroll transaction records are filtered and processed to extract key fields including block timestamps, transaction hashes, sender and receiver addresses, gas usage amounts, effective gas prices, and L1 fees. All transactions use ETH as the gas token, with the token address hardcoded as `0x5300000000000000000000000000000000000004` and symbol as `ETH`. Transaction data is cast to appropriate data types for downstream processing.
- **Key fields**: `block_timestamp`, `transaction_hash`, `from_address`, `to_address`, `gas_used`, `gas_price`, `l1_fee`

### Component B: Gas fee calculation  
- **Purpose**: Calculate total gas fees paid per day by aggregating L1 and L2 components
- **Logic**: Transaction data is aggregated by day using daily timestamp truncation. L2 gas fees are calculated by multiplying `gas_used` by `gas_price` and dividing by 1e18 to convert from wei to ETH. L1 fees are extracted directly from transaction receipts and divided by 1e18 to convert from wei to ETH. Both L1 and L2 fees are summed separately by day, token address, and chain.
- **Key fields**: `timestamp`, `l2_gas_fee`, `l1_gas_fee`, `token_address`, `chain`

### Component C: Fee aggregation and categorization
- **Purpose**: Combine L1 and L2 fees and apply business categorization
- **Logic**: L1 and L2 gas fees are summed together to calculate total daily fees in ETH. Business metadata is added including business line categorized as `blockchain`, market sector as `blockchains_l2`, and business segment as `blockchain`. The product ID is left null as fees are collected at the network level rather than for specific products.
- **Key fields**: `fees`, `business_line`, `market_sector_id`, `business_segment_id`

### Final aggregation
- **Combining components**: Total daily fees in ETH are processed through standardized metric formatting
- **Currency conversion**: ETH-denominated fees are converted to USD using end-of-day ETH price feeds through the currency conversion process, with no decimal correction needed as fees are already in proper ETH units
- **Time aggregation**: Data is aggregated to daily boundaries using day-truncated timestamps, with incremental processing for efficiency
- **Final calculation**: Revenue equals the USD value of total gas fees collected, calculated as the sum of L1 and L2 gas fees converted from ETH to USD. Missing dates are filled with zero values to ensure complete time series coverage. Chain availability filters are applied to ensure data quality and completeness.
