# Hydration Contract deployers Methodology

## 1. Overview

Contract deployers measures the number of unique addresses that have deployed at least one smart contract. It is a proxy for how many independent developers or entities actively publish code onchain. This metric is used to evaluate the growth and health of the developer ecosystem within Hydration EVM.

## 2. Data sources

- **Blockchain events**: `Executed` events from the `ethereum` pallet, covering Hydration Substrate

## 3. Step-by-step calculation

### Component A: Contract creation identification

- **Purpose**: To identify successful smart contract deployments within the Ethereum-compatible execution environment.
- **Logic**: `Executed` events are parsed from the `ethereum` pallet on Hydration Substrate. Data is filtered to include only successful transactions where an extrinsic identifier is present. The address of the contract deployer and the address of the deployed contract are extracted from the event parameters.
- **Key fields**: `event_data` (containing deployer and contract identifiers), `success` (execution status)

### Component B: Deployer aggregation and deduplication

- **Purpose**: To count the number of distinct entities publishing code on a daily basis.
- **Logic**: Unique contract deployer addresses are aggregated by day. The metric is calculated by performing a distinct count of deployer addresses that successfully initiated at least one contract deployment. Values are attributed to Hydration EVM and mapped to the UTC day of the block timestamp.
- **Key fields**: `contract_deployer`, `block_timestamp`
