# Unichain Contract deployers Methodology

## 1. Overview

The Unichain contract deployers metric measures the daily count of unique addresses that deployed smart contracts on the Unichain network. This metric provides insight into developer activity and smart contract deployment patterns on the Unichain Layer 2 blockchain. The calculation aggregates contract creation events by day and counts distinct deployer addresses using an approximate counting algorithm for efficiency.

## 2. Data sources

This metric is built from Unichain blockchain data sources:

- **Unichain transaction traces**: Raw transaction execution traces that capture contract creation operations and their associated metadata
- **Contract creation events**: Blockchain events generated when smart contracts are deployed, including deployer information, contract addresses, and deployment timestamps
- **Block and transaction data**: Unichain block timestamp information used for daily aggregation boundaries

## 3. Step-by-step calculation

### Component A: Contract creation fact table

- **Purpose**: Extract and standardize contract creation records from raw Unichain blockchain data
- **Logic**: The system processes raw contract creation data from Unichain blockchain traces, selecting distinct contract deployment records. Each record captures the deployment timestamp, the address of the account that deployed the contract (`deployer_address`), the newly created contract address, trace address information, contract bytecode, and creator address details. The `creation_timestamp` field is mapped to `block_timestamp` for standardized time handling.
- **Key fields**: `deployer_address` (the address that initiated contract deployment), `block_timestamp` (deployment timestamp), `contract_address` (newly created contract), `creation_trace_address` (transaction trace location), `contract_bytecode` (deployed contract code)

### Component B: Daily aggregation

- **Purpose**: Group contract deployments by day and count unique deployer addresses
- **Logic**: Contract creation records are aggregated using daily time boundaries by truncating timestamps to the day level. The system groups all deployments within each day and applies an approximate distinct count function to the `deployer_address` field to efficiently count unique deployers. This approach handles large datasets while maintaining accuracy for unique address counting. The aggregation includes metadata fields identifying this as Unichain data within the Layer 2 blockchain market sector.
- **Key fields**: `timestamp` (daily boundary), `contract_deployers` (count of unique deployer addresses), `chain_id` (unichain), `market_sector_id` (blockchains_l2)

### Final aggregation

- **Combining components**: The daily aggregation results are processed through a standardization macro that applies consistent formatting and handles data quality requirements
- **Gap filling**: The system applies a "fill zeros" strategy to ensure that days with no contract deployments are represented with zero values rather than missing records, providing complete time series data
- **Time aggregation**: Daily boundaries are established using timestamp truncation to ensure consistent 24-hour periods aligned to UTC day boundaries
- **Final calculation**: The final metric value represents the approximate count of distinct addresses that deployed at least one smart contract on Unichain during each calendar day, filtered by chain data availability requirements
