DeFi Yield Farming

This project focuses on developing a DeFi app which implements the concept of yield farming / liquidity mining based Dai token.

Demo of the DApp with the screenshots can be found on this wiki page.

This repository presents practices about:

Setup a blockchain.
Develop Ethereum smart contracts.
Write tests for the developed Ethereum smart contracts.
Develop a client-side website so people can actually use this application.

You can check the quick tutorial about "what is the blockchain?" in here.

Application Software Architecture

Here is the application software architecture work-flow:

Users use an Internet browser to connect front-end application which is written in HTML, CSS and JavaScript.
Then, instead of accessing a back-end server, the website talks directly to the blockchain which is where all the codes and data for the application lives.
The DeFi application codes are contained in smart contracts written in solidity progrramming language which was a lot like JavaScript. These smart contracts are immutable which means the code can not change and all the data is stored in the public ledger which is also immutable. And, anytime new data is added to the blockchain, it will be permanent and publicly verifiable.
