# Arc Contract deployers Methodology

## 1. Overview

Contract deployers is calculated as the number of unique addresses that have deployed at least one smart contract on Arc. This metric is utilized as a proxy for the number of independent developers or entities actively publishing code onchain. Developer activity is monitored to evaluate the growth and health of the Arc developer ecosystem. By tracking unique deployer addresses, insights are gained into developer adoption and smart contract deployment activity over time.

## 2. Data sources

- **Blockchain events**: Contract creation traces from the Arc chain

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Identify and extract all smart contract deployments on Arc
- **Logic**: Contract creation traces are parsed from the Arc chain. For each deployed contract, the `creation_timestamp`, `contract_address`, `deployer_address`, `creator_address`, `creation_trace_address`, and `contract_bytecode` are extracted. Only distinct contract creation records are retained to ensure data integrity.
- **Key fields**: `creation_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 contract creation records are grouped by day using the truncated `block_timestamp`. Within each daily interval, the number of unique `deployer_address` values is counted. This aggregation is performed specifically for the Arc product and chain.
- **Key fields**: `block_timestamp` (truncated to day), `deployer_address` (used for distinct counting)

### Component C: Finalization and standardization

- **Purpose**: Standardize the schema and ensure continuous daily data
- **Logic**: The aggregated daily counts are cast to standard data types and validated against approved chain and data identifiers. Days with no recorded deployment activity are populated with zero to maintain a continuous daily time series. Finally, chain availability filters are applied to align the data with the active operational window of the chain.
- **Key fields**: `timestamp` (daily boundaries), `contract_deployers` (final metric value)
