# Circle Contract deployers Methodology

## 1. Overview

Contract deployers measures the number of unique addresses that have deployed at least one smart contract. This metric is used as a proxy for how many independent developers or entities actively publish code onchain. Developer activity is tracked specifically for the Arc chain to monitor ecosystem growth and smart contract deployment trends.

## 2. Data sources

- **Blockchain events**: Contract creation records containing deployer and contract address details, covering the Arc chain

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Identify and extract all smart contract deployments on the Arc chain
- **Logic**: Contract creation records are retrieved from the shared database. For each deployment, the creation timestamp, contract address, and deployer address are extracted. Only distinct contract creations are retained to ensure data integrity.
- **Key fields**: `timestamp` (timing), `contract_address` (deployed contract identifier), `deployer_address` (deploying account identifier)

### Component B: Daily unique deployer aggregation

- **Purpose**: Aggregate the count of unique deployers on a daily basis
- **Logic**: The creation timestamps are truncated to daily granularity. The number of unique deployer addresses is calculated by counting distinct deployer addresses for each day. The data is grouped by day, chain, and product.
- **Key fields**: `timestamp` (daily truncated time), `contract_deployers` (distinct count of deployers)

### Component C: Normalization and zero-filling

- **Purpose**: Ensure data completeness and schema consistency
- **Logic**: Data types are cast to correct formats, and identifiers are validated against approved lists. Missing days in the time series are filled with zeros to ensure a continuous daily record. Chain availability filters are applied to align the data with approved chain freshness boundaries.
- **Key fields**: `timestamp` (daily truncated time), `contract_deployers` (finalized count of deployers)
