Check Out Contract on Kovan Etherscan ⏩ Contract on Etherscan

Prerequisites

Please install or have installed the following:

• nodejs and npm
• python

Installation

1. Install Brownie, if you haven't already. Here is a simple way to install brownie.

pip install --user pipx
pipx ensurepath
# restart your terminal
pipx install eth-brownie

Or if you can't get pipx to work, via pip (it's recommended to use pipx)

pip install eth-brownie

2. Clone this repo

git clone https://github.com/ShivaShanmuganathan/defi-dapp-yield-farm
cd defi-dapp-yield-farm

1. Install ganache-cli

npm install -g ganache-cli

If you want to be able to deploy to testnets, do the following.

4. Set your environment variables

Set your WEB3_INFURA_PROJECT_ID, and PRIVATE_KEY environment variables.

You can get a WEB3_INFURA_PROJECT_ID by getting a free trial of Infura. At the moment, it does need to be infura with brownie. You can find your PRIVATE_KEY from your ethereum wallet like metamask.

You'll also need testnet Kovan ETH and LINK. You can get LINK and ETH into your wallet by using the Kovan faucets located here.

You'll also want an Etherscan API Key to verify your smart contracts.

You can add your environment variables to the .env file:

export WEB3_INFURA_PROJECT_ID=<PROJECT_ID>
export PRIVATE_KEY=<PRIVATE_KEY>
export ETHERSCAN_TOKEN=<YOUR_TOKEN>

DO NOT SEND YOUR KEYS TO GITHUB If you do that, people can steal all your funds. Ideally use an account with no real money in it.

Useage

Scripts
