# Ethereum Contract deployers Methodology

## 1. Overview

The Ethereum contract deployers metric counts the number of unique addresses that deployed smart contracts on the Ethereum blockchain each day. This metric measures developer and deployment activity on Ethereum by tracking how many distinct entities are creating new smart contracts daily. The calculation aggregates all contract creation events by day and counts unique deployer addresses, providing insights into the level of development activity and ecosystem growth on Ethereum.

## 2. Data sources

The calculation relies on the following raw data sources:
- **Ethereum contract creation records**: Comprehensive records of all smart contract deployments on the Ethereum blockchain, including deployer addresses, deployed contract addresses, creation timestamps, and transaction trace information
- **Ethereum transaction traces**: Transaction execution traces that capture contract creation operations and their metadata
- **Blockchain metadata**: Chain availability and data quality indicators for filtering and validation

## 3. Step-by-step calculation

### Component A: Contract creation data extraction
- **Purpose**: Identifies all contract deployment events on Ethereum with their associated deployer addresses
- **Logic**: Extracts distinct contract creation records from Ethereum blockchain data, capturing the `creation_timestamp` when each contract was deployed, the `contract_address` of the newly created contract, the `deployer_address` of the entity that created the contract, and the `creation_trace_address` for transaction tracing. Each record represents a unique contract deployment event.
- **Key fields**: `creation_timestamp` (when contract was created), `contract_address` (deployed contract), `deployer_address` (creator), `creation_trace_address` (trace location)

### Component B: Daily aggregation and counting
- **Purpose**: Groups contract creations by day and counts unique deployer addresses
- **Logic**: Truncates the `creation_timestamp` to day-level boundaries to create daily buckets. Groups all contract creation events by day and counts distinct `deployer_address` values within each day. This ensures that if the same address deploys multiple contracts in a single day, they are only counted once. Adds standard metadata including chain identifier as ethereum, market sector as blockchains_l1, and business segment as blockchain.
- **Key fields**: `timestamp` (truncated to day), `contract_deployers` (count of distinct deployers), chain and sector metadata

### Final aggregation
- **Combining components**: The daily aggregated data flows through the finalize_metric_contract_deployers macro which applies standardized formatting and implements a fill_zeros strategy to ensure consistent daily data points even when no contract deployments occur
- **Currency conversion**: Not applicable for this count-based metric
- **Time aggregation**: Data is aggregated at daily boundaries using timestamp truncation, with each day representing a complete 24-hour period in UTC
- **Final calculation**: The final metric value is the count of distinct deployer addresses per day, processed through data quality filters to ensure chain availability and reliability. Missing days are filled with zero values to maintain consistent time series data.

Ethereum

Validators process transactions and receive fees from users (supply-side fees).

Ethereum is a smart contract platform for decentralized applications (a blockchain). Ethereum was founded by Vitalik Buterin, Anthony Di Iorio, Mihai Alisie, etc. and launched in 2015.

ETH holders own and govern the protocol. They currently take a cut of the total transaction fees (base fee) paid by users (revenue). Ethereum’s investors include KR1, Block Ventures, 8 Decimal Capital, etc.
