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 Cost of revenue Methodology

## 1. Overview

Cost of revenue for Scroll represents the daily costs incurred by the protocol to settle transactions on Ethereum Layer 1. This metric captures the actual gas expenses paid by Scroll's sequencer when posting transaction batches and state commitments to Ethereum mainnet. The calculation identifies all settlement transactions sent by Scroll's sequencer address and aggregates the associated gas costs, including both standard gas fees and blob gas fees (EIP-4844), converted to USD values.

## 2. Data sources

- **Ethereum transaction records**: Complete transaction data from Ethereum mainnet including recipient addresses, gas usage, gas prices, and blob gas information
- **End-of-day token price feeds**: Daily ETH/USD price data for currency conversion
- **Token metadata**: ETH token information including decimal places and symbol data

## 3. Step-by-step calculation

### Component A: Settlement transaction identification

- **Purpose**: Identify all Ethereum transactions representing Scroll's Layer 1 settlement activity
- **Logic**: Filter Ethereum transaction records to isolate transactions sent to Scroll's sequencer contract address `0xa13baf47339d63b743e7da8741db5456dac1e556`. Extract key transaction details including block timestamp, transaction hash, gas pricing information (both `receipt_effective_gas_price` and `receipt_blob_gas_price`), gas usage amounts (`receipt_gas_used` and `receipt_blob_gas_used`), and transaction index. Associate each transaction with wrapped ETH token address `0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2` since settlement costs are paid in ETH.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` for unique identification, `gas_price` and `blob_gas_price` for cost calculation, `gas_used_amount` and `blob_gas_used_amount` for volume metrics

### Component B: Settlement cost calculation

- **Purpose**: Calculate the actual ETH cost for each settlement transaction
- **Logic**: For each identified settlement transaction, compute the total settlement cost by multiplying gas used by the effective gas price, plus blob gas used by blob gas price (with null values treated as zero for transactions without blob gas usage). Convert the resulting wei amount to ETH by dividing by 10^18. This captures both traditional gas costs and the newer blob gas costs introduced with EIP-4844.
- **Key fields**: `l1_settlement_amount` representing the ETH cost per transaction, `gas_price` and `blob_gas_price` for pricing components, gas usage amounts for volume calculation

### Component C: Daily aggregation

- **Purpose**: Aggregate individual settlement costs into daily totals
- **Logic**: Group settlement transactions by day using timestamp truncation to daily boundaries. Sum all `l1_settlement_amount` values within each day to get total daily settlement costs. Assign standardized metadata including chain identifier as 'ethereum', market sector as 'blockchains_l2', business segment as 'blockchain', and maintain token address information. Set timestamp grain as 'day' and leave product identifier as null since this applies to the entire protocol.
- **Key fields**: `timestamp` truncated to day, `cost_of_revenue` as the summed daily settlement amount, standardized classification fields

### Final aggregation

- **Combining components**: Daily settlement costs flow directly from the aggregation step as the `cost_of_revenue` field
- **Currency conversion**: Convert ETH settlement costs to USD using end-of-day ETH price feeds through the standard conversion macro, maintaining precision without decimal correction since ETH amounts are already properly denominated
- **Time aggregation**: Data is aggregated at daily boundaries using timestamp truncation, ensuring consistent daily reporting periods
- **Final calculation**: The final cost of revenue metric represents the total USD value of gas fees paid daily by Scroll's sequencer for settlement transactions on Ethereum, including both standard gas costs and blob gas costs, with gap-filling applied to ensure zero values for days with no settlement activity
