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.

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)
