Dapp Demo

A example of a decentralized app that utilizes a smart contract to transfer funds (link to slides with instructions/solutions).

Setup

Make sure you have Node, the Metamask extension, and Git installed.

1. Clone the repo

$ git clone https://github.com/jp3hou/dapp-demo
$ cd dapp-demo

2. Install dependencies using npm

$ npm install

3. Compile the smart contracts with truffle

$ npm run compile

4. Run a local blockchain server using ganache

$ npm run blockchain

5. Deploy smart contracts onto your blockchain server

$ npm run migrate

6. Start your frontend server

$ npm run start

Open your browser to http://localhost:3000 to see your local environment! The constructor in the KatCoin.sol contract auto-mints 30 KatCoins and displays them in the frontend React app.
