# Ethereum Active Users Checker

A simple JavaScript function to estimate the number of active users on the Ethereum blockchain using the Etherscan API.

## Overview

This project provides a JavaScript function that asynchronously fetches the total ether supply from the Etherscan API and estimates the number of active users on the Ethereum blockchain based on that supply.

## Prerequisites

- Node.js installed on your machine.
- An API key from Etherscan. You can sign up [here](https://etherscan.io/apis).

## Installation

1. Clone this repository:

git clone https://github.com/yourusername/ethereum-active-users.git

2. Navigate to the project directory:

cd ethereum-active-users

3. Install dependencies:

npm install

4. Open `index.js` and replace `'Your_Etherscan_API_Key'` with your actual Etherscan API key.

## Usage

The `getActiveUsersCount()` function asynchronously fetches the total ether supply from the Etherscan API and estimates the number of active users on the Ethereum blockchain.

```javascript
const { getActiveUsersCount } = require('./index');

getActiveUsersCount()
    .then(activeUsersCount => {
        if (activeUsersCount !== null) {
            console.log("Number of active users on Ethereum chain:", activeUsersCount);
        } else {
            console.log("Failed to fetch active users count.");
        }
    });
