Rari Capital's local fork

This project eases the process of setting up a hardhat localfork with Rari Capital's products.

Setup

1. You first run

    npm install 
   

2. The next step is compilation but one contract needs to be modified before because of incompatible solidity compilator versions

   Go to node_modules/@uniswap/v3-core/contracts/libraries/LowGasSafeMath.sol

   in Line 2 you'll find: pragma solidity >=0.7.0;

   change it to: pragma solidity 0.6.12;

   _{please let me know if theres a better way to do this I couldn't find it :)}

3. Run

    npx hardhat compile
   

4. Start hardhat node

    npx hardhat node
   

   This will start a mainnet fork pinned at block: 14167154

5. Open a second terminal and run:

    npx hardhat deploy-fuse --network localhost 
   

   This will deploy a clean instance of fuse in your localnode.

Fuse

Interacion

Go through the setup before using any task below.

Deploy an empty pool

	npx hardhat deploy-pool --network localhost

This task will output the deployed pool's comptroller address which you will need to run the tasks below:

Deploy a cToken/market

	npx hardhat deploy-market --comptroller 0x00...0000 --underlying 0x00...0000 --cfactor 5 --rfactor 0.5 --adminfee 0.05 --network localhost 

- comptroller is the comptroller address where ctoken/market will be listed.

- underlying is the underlying token of the market.

- cfactor is the collateral factor of the market. optional

- rfactor is the reserve factor. optional.

- adminfee is the admin fee. optional.

Deploy a rewards distributor to a given pool

npx hardhat deploy-rd-to-pool --underlying 0x00...0000 --comptroller 0x00...0000 --network localhost

- underlying is the address of token to distribute.

- comptroller is the comptroller address to add rd.

Deploy Uniswap V2 Twap Oracle

npx hardhat deploy-unitwap-v2

task not complete yet, it'll deploy an oracle but will not add it to the comptroller.

- token is the market's underlying asset.

Withdraw

npx hardhat withdraw --market 0x00...0000 --amount 1000 --token 0x00..0000

- market is the address of the market.

- amount is the amount of tokens to supply.

- token is the market's underlying asset.

Fetching info

Go through the setup, and deploy a pool before using tasks below.

To get the pool's information

npx hardhat get-pool-info --comptroller 0x00...0000 --network localhost

- comptroller is the address of the comptroller that will be used to get information.
