# Unique Network EVM Contract deployers Methodology

## 1. Overview

Contract deployers measures the number of unique addresses that have deployed at least one smart contract on Unique Network EVM. This metric serves as a proxy for the volume of independent developers or entities actively publishing code on-chain. It helps quantify the growth and activity of the developer ecosystem within the Unique Network EVM environment.

## 2. Data sources

- **Blockchain events**: `Executed` events from the `ethereum` pallet, covering Unique Network

## 3. Step-by-step calculation

### Component A: Deployment event extraction

- **Purpose**: Identify successful smart contract creation transactions on the EVM-compatible layer.
- **Logic**: Successful `Executed` events are parsed from the `ethereum` pallet. For each event, the deployer address and the resulting contract address are extracted from the event data. Only transactions marked as successful with a valid extrinsic ID are included to ensure only completed deployments are counted.
- **Key fields**: `contract_deployer` (the address initiating the deployment), `contract_deployed` (the address of the new smart contract), and `block_timestamp`.

### Component B: Unique deployer aggregation

- **Purpose**: Count the number of distinct entities deploying code.
- **Logic**: The first occurrence of each unique contract deployment is identified to prevent duplicate counting of the same contract. The number of unique `contract_deployer` addresses is then calculated.
- **Key fields**: `contract_deployer`

### Component C: Daily normalization and finalization

- **Purpose**: Format the data into a daily time series for the Unique Network EVM product.
- **Logic**: The count of unique deployers is aggregated by UTC day. A zero-filling strategy is applied to ensure a continuous time series, where days with no deployment activity are assigned a value of zero. The data is filtered based on the known availability and freshness of the underlying chain data.
