DeFi Intro Full Course

• This repository contains examples for a Lending Pool and a Decentralized Exchange.
• The contracts are based in the project https://github.com/smartcontractkit/defi-minimal of Patrick from chainlink, slightly modified.
• All of these contracts are for educational purposes only and are not intended to be used in production code.

Lending Pool Instructions

• Files needed
  • Mock Oracle
  • Aggregator V3 Interface to interact with the mock oracle
  • Token this is to have a token to work with
  • Lending Pool
  • All files above should be in the same directory
• Order of Deployment
  • First deploy your token.
  • Deploy the mock oracle, you will need to define a price in eth that the mock oracle will return.
  • Deploy the lending pool
  • In the lending pool whitelist your token.
    • This is done by calling the set allowed token function in the lending contract.
    • for calling this function you will need the address in which your token and the mock oracle were deployed.

Decentralized Exchange Instructions

• For details on the theory rewatch the video in moralis youtube channel or read. https://github.com/smartcontractkit/defi-minimal/tree/main/docs/uniswap-v1
• Files needed
  • Token this will be the token deposited against eth in the liquidity pool.
  • Factory this contract is used to create liquidity pools.
  • Exchange contract, this will be deployed by the Factory contract.
  • All files above should be in the same directory
• Order of Deployment
  • First deploy the token
  • Deploy the factory
  • In the Factory contract call the create exchange function. This function takes the address of your contract as a parameter.
    • The create exchange function returns the address of the created exchange.
    • To interact with the liquidity pool you will need to create an exchange contract object at that address. The video shows how to do that in Remix.
