# X Layer Contract deployers Methodology

## 1. Overview

The number of unique addresses that have deployed at least one smart contract on X Layer is measured by the Contract deployers metric. This metric is utilized as a proxy for the number of independent developers or entities actively publishing code onchain. Developer engagement and ecosystem growth on X Layer are monitored through the aggregation of these unique deployer addresses over time.

## 2. Data sources

- **Blockchain events**: Contract creation records extracted from system contracts, covering X Layer

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Identify all smart contracts deployed on X Layer
- **Logic**: Contract creation transactions are parsed from the X Layer ledger. For each contract deployment, the contract address, deployer address, creation timestamp, and bytecode are extracted. Only unique contract creation events are retained to prevent duplicate counting.
- **Key fields**: `deployer_address` (the address initiating the deployment), `timestamp` (the time of deployment)

### Component B: Daily unique deployer aggregation

- **Purpose**: Calculate the daily count of unique contract deployers
- **Logic**: The deployment timestamps are truncated to daily granularity. For each day, the number of unique deployer addresses is aggregated by counting distinct deployer addresses associated with contract creations on X Layer.
- **Key fields**: `deployer_address` (for distinct counting), `timestamp` (for daily grouping)

### Component C: Normalization and zero-filling

- **Purpose**: Ensure data consistency and completeness across the time series
- **Logic**: The aggregated daily counts are cast to the appropriate numeric data types. 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 the active operational window of X Layer.
- **Key fields**: `timestamp` (for time series alignment), `contract_deployers` (the final metric value)
