# OKX Contract deployers Methodology

## 1. Overview

Contract deployers is measured as the number of unique addresses that have deployed at least one smart contract on X Layer. This metric is utilized as a proxy for the number of independent developers or entities actively publishing code onchain. Developer activity and ecosystem growth are monitored through this metric to assess the overall health and adoption of the network.

## 2. Data sources

- **Blockchain events**: Contract creation transactions and deployment traces on X Layer

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Identify all smart contract deployments on X Layer
- **Logic**: Contract creation records are extracted from the blockchain. For each deployment, the block timestamp, contract address, deployer address, and creator address are identified. Only distinct contract creations are retained to prevent duplicate counting.
- **Key fields**: `creation_timestamp` (timing), `contract_address` (deployed contract identifier), `deployer_address` (deploying account identifier)

### Component B: Daily unique deployer aggregation

- **Purpose**: Aggregate the number of unique deployers on a daily basis
- **Logic**: The block timestamps are truncated to daily granularity. The number of unique deployer addresses is calculated by counting distinct deployer addresses for each day.
- **Key fields**: `block_timestamp` (truncated to day), `deployer_address` (used for distinct counting)

### 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 data types. Missing days in the time series are filled with zeros to ensure a continuous dataset. Chain availability filters are applied to align the data with approved freshness boundaries.
- **Key fields**: `timestamp` (daily boundary), `contract_deployers` (final count of unique deployers)
