Local Setup

Downloading dependencies

1. Clone the repo using git clone and cd into the folder
2. Run npm install to download all the dependencies

Compiling the smart contract

1. cd into the ethereum folder and run node compile.js

Above command will compile the contract using solc and outputs the json files under ethereum/build

Deploying the smart contract to Rinkeby

Before deploying the contract, you need to set the WALLET SEED and the RINKEBY network url inside the file ethereum/deploy.js

The WALLET SEED is the 12 word mnemonic phase for your wallet. The RINKEBY network url can be obtained by signing up at Infura.io

Once the values are set run node depoloy.js under ethereum folder.

When the contract is successfully deployed, above command console logs the contract address of the newly deployed contract.

Note this contract address as this needs to be set in the .env file

Process environment variables

Rename .env.default to .env and supply the necessary values
