Testing smart contracts

"npm run block:test"

Set up to run locally

1. npm install
2. Install Ganache and start it up locally(this is our local blockchain network)
3. Connect MetaMask to local blockchain network and import private key of 2nd address in Ganache(note: the 1st address is used by Token Farm, 2nd address used by investor)
4. Run smart contract deployment script "npm run block:deploy" (note: whenever a change is made to smart contract make sure to compile by running "npm run block:compile")
5. Start React app "npm run start"
6. Go to localhost:3000/ in the browser
7. Stake, unstake and earn interest!!

On init deployment

After smart contracts are deployed to Blockchain, we transferr 1 million Dapp tokens to the Token Farm(Digital Bank) and also transefer 100 Dai tokens to the investors wallet.
