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 Fees Methodology

## 1. Overview

The Scroll fees metric measures the total daily transaction fees generated on the Scroll L2 blockchain network, expressed in USD. This metric captures both L1 data availability costs and L2 execution fees that users pay for transactions, providing insight into network usage and revenue generation. The calculation aggregates all transaction fees across the network on a daily basis, combining the L2 execution costs with L1 submission fees that are characteristic of Layer 2 rollup architectures.

## 2. Data sources

The calculation relies on the following data sources:
- **Scroll blockchain transactions**: Complete transaction records from the Scroll L2 network including gas usage, gas prices, and L1 fee components
- **End-of-day price feeds**: ETH/USD exchange rates for currency conversion
- **Token metadata**: ETH token information and decimal specifications for the Scroll network

## 3. Step-by-step calculation

### Component A: Transaction data extraction
- **Purpose**: Extract and standardize transaction-level fee data from raw Scroll blockchain records
- **Logic**: Raw Scroll transaction data is processed to extract key fee components including `gas_used`, `receipt_effective_gas_price`, and `receipt_l1_fee` fields. The token address is standardized to `0x5300000000000000000000000000000000000004` representing ETH on the Scroll network, with transactions timestamped using `block_timestamp`
- **Key fields**: `gas_used` (execution gas consumed), `gas_price` (effective gas price), `l1_fee` (L1 data availability cost), `block_timestamp` (transaction timing)

### Component B: Gas fee calculation and aggregation
- **Purpose**: Calculate L1 and L2 fee components and aggregate them daily
- **Logic**: For each transaction, L2 gas fees are calculated by multiplying `gas_used` by `gas_price`, then dividing by 1e18 to convert from wei to ETH. L1 gas fees are calculated by dividing `l1_fee` by 1e18 to convert from wei to ETH. All transactions are then grouped by day using timestamp truncation, and fees are summed across all transactions within each day
- **Key fields**: `l2_gas_fee` (daily aggregated L2 execution fees), `l1_gas_fee` (daily aggregated L1 data availability fees), `timestamp` (daily boundaries)

### Final aggregation
- **Combining components**: The total daily fees are calculated by adding `l1_gas_fee` and `l2_gas_fee` for each day, representing the complete fee structure of the Layer 2 rollup architecture
- **Currency conversion**: ETH fee amounts are converted to USD using end-of-day price feeds through the currency conversion process
- **Time aggregation**: Data is aggregated at daily boundaries using timestamp truncation to the day level
- **Final calculation**: The final metric represents total daily fees in USD, classified under the 'blockchains_l2' market sector with 'blockchain' business segment designation, and validated through schema enforcement with zero-filling for any gaps in the time series
