Managed to run this. You need to create .env file in project root and link node url and private key

cnspot commented 4 years ago

.env file like this:

INFURA_URL="wss://mainnet.infura.io/ws/v3/XXXXXXXXXXXXXXXXXXXXXX" PRIVATE_KEY="69xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

olegmitrakhovich commented 4 years ago

this is correct, you need to make a .env file and get your own infura_url API key. Also, create a new ETH wallet address and extract your private key to store in your .env file just like cnspot mentioned above. Make sure your new wallet address has ETH inside.
