# Katana Chain Contract deployers Methodology

## 1. Overview

Contract deployers measures the number of unique addresses that have deployed at least one smart contract. It is utilized as a proxy for the number of independent developers or entities that actively publish code on-chain. This metric is used to evaluate the growth and developer adoption of Katana Chain.

## 2. Data sources

- **Blockchain events**: Contract creation records from Katana Chain

## 3. Step-by-step calculation

### Component A: Contract creation identification

- **Purpose**: Identify all smart contract deployment transactions on Katana Chain
- **Logic**: Contract creation data is extracted from the Katana Chain ledger. For every successful deployment, the `deployer_address` and the `creation_timestamp` are captured. This includes all unique contract addresses generated by a deployer.
- **Key fields**: `deployer_address`, `creation_timestamp`

### Component B: Unique deployer aggregation

- **Purpose**: Calculate the daily count of unique developers
- **Logic**: The `deployer_address` values are grouped by day based on the `creation_timestamp`. A distinct count of these addresses is performed for each 24-hour period. The data is filtered to ensure only records from Katana Chain are included. Any days without recorded activity are zero-filled to maintain a continuous time series.
- **Key fields**: `deployer_address`, `creation_timestamp`
