zkSync Era batches users' transactions and submits them to Ethereum together with a zero-knowledge proof, paying a share of the transaction fees to Ethereum validators (expense).

zkSync Era is an L2 smart contract platform for decentralized applications on Ethereum. zkSync Era was founded by Matter Labs and launched in 2023.

Matter Labs team owns and governs the protocol. Matter Labs' investors include a16z, Lightspeed Venture Partners, Blockchain Capital, etc.

# zkSync Era Revenue Methodology

## 1. Overview

zkSync Era revenue represents the total gas fees collected by the zkSync Era Layer 2 network from user transactions. This metric answers the business question: "How much revenue does zkSync Era generate from transaction fees?" The calculation approach treats all gas fees paid by users as protocol revenue, since zkSync Era's business model is based on collecting transaction fees to sustain network operations.

## 2. Data sources

- **Blockchain transactions**: Raw zkSync Era transaction records containing gas usage and pricing information
- **End-of-day price feeds**: Token price data for converting ETH-denominated fees to USD values
- **Token metadata**: Decimal precision information for accurate currency conversion
- **Hardcoded constants**: WETH contract address (`0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2`) used as the fee token identifier

## 3. Step-by-step calculation

### Component A: Transaction data extraction
- **Purpose**: Extract gas fee information from all zkSync Era transactions
- **Logic**: Pull transaction records and calculate gas costs by combining gas usage with effective gas prices. Convert gas prices from wei to ETH by dividing by 10^18. Set the fee token as WETH since zkSync Era uses ETH for gas payments. Include transaction metadata like block timestamp, transaction hash, and addresses for traceability.
- **Key fields**: `block_timestamp`, `gas_used`, `effective_gas_price`, `token_address` (set to WETH), `token_symbol` (set to 'ETH')

### Component B: Daily fee aggregation
- **Purpose**: Calculate total daily gas fees collected by the protocol
- **Logic**: Group transactions by day using timestamp truncation and aggregate fees by summing the product of `gas_used` multiplied by `effective_gas_price` for each transaction. This gives the total ETH-denominated fees collected each day.
- **Key fields**: `timestamp` (truncated to day), `token_address`, `fee_amount`

### Component C: USD conversion and business classification
- **Purpose**: Convert ETH fees to USD and apply business categorization
- **Logic**: Use Token Terminal's conversion system to convert ETH-denominated fees to USD using end-of-day price feeds. Apply business classifications including market sector as `blockchains_l2`, business segment as `blockchain`, and initially set chain identifier as `ethereum` (later corrected to `zksyncera`).
- **Key fields**: `fees` (in USD), `market_sector_id`, `business_segment_id`, `chain_id`

### Final aggregation
- **Combining components**: The calculation flows sequentially through each component without complex joins - each step processes the output of the previous step
- **Currency conversion**: ETH fees are converted to USD using end-of-day price feeds through Token Terminal's standardized conversion methodology
- **Time aggregation**: Daily boundaries are determined by truncating timestamps to day level, ensuring consistent daily reporting
- **Final calculation**: The final revenue metric is simply the USD-converted daily gas fees, with fees directly aliased as revenue since zkSync Era's business model treats all collected gas fees as protocol revenue

Fee revenue retained after supply-side payouts. Before cost of revenue (e.g. L2 DA fees) and before operating expenses.
