Configuration to deploy the contract on Rinkeby Ethereum Testnet.

When you deploy the contract on Rinkeby Ethereum Testnet, you need to add and modify truffle-config.js file on the root folder by using your Metamask’s seed and Infura setup.

The code of truffle-config.js should look something as follows:

const HDWalletProvider = require('truffle-hdwallet-provider');
const infuraKey = "<Infura Project Id>";
//
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();

For metamask we create a .secret file and put the secret there. For infurakey, just set your project id api key from Infura.

Develop the project

• For starting the development console, run:

  truffle develop

• For compiling the contract, inside the development console, run:

  compile

• For migrating the contract to the locally running Ethereum network, inside the development console, run:

  migrate --reset

• For running unit tests the contract, inside the development console, run:

• For running the Front End of the DAPP, open another terminal window and go inside the project directory, and run:

  cd app

  npm run dev
