Welcome to lottery-ethereum 👋



  

    

  

  

    

  

  

    

  



#### A lottery application built on the ethereum network powered by smart contract, the client communicates with lottery system thanks to a react app.

### 🏠 [Homepage](https://github.com/nour-karoui/lottery-ethereum)

## Install

```sh

> git clone https://github.com/nour-karoui/lottery-ethereum.git

> cd lottery

> npm install

> npm run test

> cd lottery/client

> npm install

> npm start

```

## How It Works

A user simply chooses an amount of ether to send in order to enter the lottery, this amount should be bigger than 0.1 ether.



 











A manager selects randomly a winner

The winner gets all the ether collected in the lottery, and the game resets.

 



***PS***: In order to test this app, you need to have metamask extension installed, and have ether in your rinkeby network account.

You can fund your account through [faucet.rinkeby.io](https://faucet.rinkeby.io/).

## Under The Hood

* The contract is deployed in infura *(check **deploy.js**)*

* the client side communicates with the smart contract thanks to web3 *(check **client/src/web3.js** && **client/src/lottery.js**)*

* the smart contract is tested with mocha and ganache cli *(check **test/Lottery.test.js**)*
