Initial Setup

Install NVM and the latest version of NodeJS 12.x

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash 
# Restart terminal and/or run commands given at the end of the installation script
nvm install 12
nvm use 12

Use Git to pull down the BarnBridge-SmartYieldBonds repository from GitHub

git clone https://github.com/BarnBridge/BarnBridge-YieldFarming.git
cd BarnBridge-YieldFarming

Updating the .env file

Create an API key with a Provider such as Infura to deploy to Ethereum Public Testnet. In this guide, we are using Kovan.

1. Navigate to Infura.io and create an account
2. Log in and select "Get started and create your first project to access the Ethereum network"
3. Create a project and name it appropriately
4. Switch the Endpoint to Kovan and copy the HTTPS URL into the PROVIDER section section in the .env file
5. Finally, insert the mnemonic phrase for your testing wallet into the MNEMONIC section in the .env file. You can use a MetaMask instance, and switch the network to Rinkeby on the upper right. DO NOT USE YOUR PERSONAL METAMASK SEED PHRASE; USE A DIFFERENT BROWSER WITH AN INDEPENDENT METAMASK INSTALLATION
6. You'll need some Kovan-ETH (it is free) in order to pay the gas costs of deploying the contracts on the TestNet; you can use your GitHub account to authenticate to the KovanFaucet and receive 2 Kovan-ETH for free every 24 hours

Create an API key with Etherscan

1. Navigate to EtherScan and create an account
2. Log in and navigate to MyAPIKey
3. Use the Add button to create an API key, and paste it into the ETHERSCAN section of the .env file.
