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 Contracts deployed Methodology

## 1. Overview

The zkSync Era contracts deployed metric measures the daily number of smart contracts deployed on the zkSync Era Layer 2 network. This metric tracks ecosystem growth and developer activity by counting unique contract creation events that occur each day. The calculation aggregates contract deployment transactions from zkSync Era blockchain data and presents the results as a daily time series with zero-filling for complete historical coverage.

## 2. Data sources

The metric uses the following raw data sources:
- **zkSync Era contract deployment records**: Comprehensive data about smart contracts deployed on the zkSync Era network, including deployment timestamps, contract addresses, deployer addresses, and transaction trace information
- **zkSync Era transaction traces**: Detailed execution traces of transactions that result in contract creation, capturing the deployment process and associated metadata
- **zkSync Era block timestamps**: Block-level timing information to establish when contract deployments occurred on the network

## 3. Step-by-step calculation

### Component A: Contract creation extraction
- **Purpose**: Identifies and extracts all unique contract deployment events from zkSync Era blockchain data
- **Logic**: The system processes zkSync Era contract deployment records to extract distinct contract creation events. Each record includes the `creation_timestamp` indicating when the contract was deployed, the `contract_address` of the newly created contract, the `deployer_address` of the account that initiated the deployment, and the `creation_trace_address` showing the transaction trace location. Deduplication ensures each contract deployment is counted exactly once, preventing double-counting from multiple data processing passes.
- **Key fields**: `block_timestamp` (deployment timing), `account_address` (deployed contract), `deployer_address` (deploying account), `creation_trace_address` (trace location)

### Component B: Daily aggregation
- **Purpose**: Groups contract deployments by day and counts the total deployments per day
- **Logic**: The system truncates the contract creation timestamps to daily boundaries using day-level time truncation. All contract deployments occurring within the same calendar day are grouped together. The system then counts the total number of distinct contracts deployed each day using a count aggregation. Standard blockchain metadata is added including chain identifier for zkSync Era, market sector classification as Layer 2 blockchain, and business segment as blockchain infrastructure.
- **Key fields**: `timestamp` (daily boundary), `contracts_deployed` (daily count), `chain_id` (zksyncera), `market_sector_id` (blockchains_l2), `business_segment_id` (blockchain)

### Final aggregation
- **Combining components**: The daily contract deployment counts are processed through the finalize metric macro which standardizes the output format and applies data quality controls
- **Currency conversion**: No currency conversion required as this is a count-based metric
- **Time aggregation**: Daily boundaries are established by truncating timestamps to day level, ensuring all deployments within a 24-hour period are grouped together
- **Final calculation**: The final metric value represents the total count of unique smart contracts deployed on zkSync Era for each calendar day, with zero-filling applied to ensure continuous daily time series data even for days with no deployments. Chain availability filtering ensures data quality and completeness across the historical time range.
