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 Contract deployers Methodology

## 1. Overview

The zkSync Era contract deployers metric measures the daily count of unique addresses that deploy smart contracts on the zkSync Era network. This metric provides insight into developer activity and ecosystem growth by tracking how many distinct entities are creating new contracts each day. The calculation uses an approximate distinct count approach to efficiently process large volumes of contract creation data.

## 2. Data sources

- **zkSync Era contract creation data**: Records of all smart contracts deployed on the zkSync Era network, including deployer addresses, contract addresses, creation timestamps, and trace information
- **zkSync Era blockchain transaction data**: Underlying transaction data from the zkSync Era network that captures contract deployment activities
- **Contract deployment events**: Raw blockchain events and transaction traces that document when new contracts are created on the network

## 3. Step-by-step calculation

### Component A: Contract creation extraction
- **Purpose**: Identifies all contract creation events on zkSync Era with relevant metadata
- **Logic**: Extracts distinct contract creation records from zkSync Era blockchain data, capturing the `deployer_address`, `contract_address`, `creation_timestamp`, and `creation_trace_address` for each deployment event. Deduplication is applied to ensure each contract creation is counted only once.
- **Key fields**: `creation_timestamp` (renamed to `block_timestamp`), `deployer_address`, `contract_address`, `creation_trace_address`

### Component B: Daily aggregation
- **Purpose**: Groups contract creations by day and counts unique deployers
- **Logic**: Truncates the `block_timestamp` to daily boundaries using timestamp truncation. Groups all contract creations by day and applies approximate distinct counting to the `deployer_address` field. This counts how many unique addresses deployed contracts each day, regardless of how many contracts each address deployed.
- **Key fields**: Truncated `timestamp`, `contract_deployers` (approximate distinct count of deployer addresses)

### Final aggregation
- **Combining components**: The daily aggregated data is enhanced with metadata fields including `chain_id` set to 'zksyncera', `market_sector_id` set to 'blockchains_l2', `business_segment_id` set to 'blockchain', and `product_id` set to null
- **Currency conversion**: Not applicable for this count-based metric
- **Time aggregation**: Daily boundaries are established by truncating timestamps to day precision
- **Final calculation**: The final metric value represents the approximate count of distinct deployer addresses that created contracts on each day on zkSync Era. A fill-zeros strategy is applied to ensure missing days show zero deployers rather than null values. Chain availability filtering ensures data quality by excluding periods where blockchain data may be incomplete or unreliable.
