Core Smart Contracts

Contract Overview

Tropykus Finance utilizes several key smart contracts, including:

• cToken.sol: Handles deposits, withdrawals, interests, and liquidations for lenders and borrowers on the markets.

• Unitroller: Handles the administrative and share logic of the protocol

Interacting with Contracts

Setting Up

1. Clone the repository: Clone the repository from Github https://github.com/Tropykus/protocol-rsk

2. Environment Setup: Ensure you have Node.js installed and set up the Truffle Suite or Hardhat for compiling and deploying smart contracts.

3. Install Dependencies: Run npm installto handle upgrades and secure your smart contracts.

Interaction with the protocol

// Import the ABI of the lending pool

import { ethers } from 'ethers'
import UnitrollerABI from "./abis/UnitrollerABI.json";
import ERC20ABI from "./abis/ERC20ABI.json";
import CTokenABI from "./abis/CTokenABI.json";
import CRBTCABI from "./abis/CRBTCABI.json";

[signer] = await ethers.getSigners()
const UnitrollerAddress = "0x123...";
const DOCAddress = "0x456....";
const kDOCAddress = "0x789...";
const kRBTCAddress = "0xa01...";

const unitroller = new ethers.Contract(UnitrollerAddress, UnitrollerABI, signer);
const doc = new ethers.Contract(DOCAddress, ERC20ABI, signer);
const kdoc = new ethers.Contract(kDOCAddress, CTokenABI, signer);
const kcrbtc = new ethers.Contract(kRBTCAddress, CRBTCABI, signer);

//Enter markets
await comp.connect(dep).enterMarkets([kdoc.address, krbtc.address]) 

// Deposit Assets
await doc.connect(dep).approve(kdoc.address, ethers.utils.parseEther('10'))	
await kdoc.connect(dep).mint(ethers.utils.parseEther('10'), { gasLimit: 2500000 })  amount in underlying

await krbtc.connect(dep).mint({value: ethers.utils.parseEther('0.1'), gasLimit: 2500000})  

// Borrow assets				
await kdoc.connect(dep).borrow(ethers.utils.parseEther('2'), { gasLimit: 250000 })
// Check the borrow balance
Number(await kdoc.callStatic.borrowBalanceCurrent(dep.address))/1e18

// Withdraw Assets
await kdoc.connect(dep).redeemUndeem(ethers.utils.parseEther('10'))

// Repay debts
await doc.connect(dep).approve(kdoc.address, ethers.utils.parseEther('1'))	3E+18
await kdoc.connect(dep).repayBorrow(ethers.utils.parseEther('1'),{ gasLimit: 2500000}) amount in underlying
