Lending Protocol dApp

Encode Solidity Bootcamp Q3 - Final Project

Group 6 Lending Protocol

Decentralized Lending application that enables supplying of ETH as collateral in order to borrow USDC. Accounts can also earn interest by supplying USDC to the protocol.

The Lending dApp operates under three tokens: native Sepolia ETH, USDC and our very own G6T.

On the Lend side users can make their USDC available to other users looking for a loan by depositing into the Liquidity Pool. As an incentive Lenders receive G6T token rewards under a set APR rate while also sharing a part of the protocol fees payed by the Borrowers.

On the Borrow side users can deposit ETH as collateral and borrow up to 80% of the corresponding value in USDC. Once this happens interest fees start accruing until the total debt is repayed or until the debt value surpasses the value of the deposited collateral, by wich they are liquidated, losing the deposited ETH.

To facilitate interactions with the protocol there are also two interfaces to swap between ETH/G6T and ETH/USDC, provided by the protocol.

The application was implemented using React/Next.js and Wagmi hooks to interact with the smart contracts.

Setup:

1. Clone the repository.
2. Install dependencies with npm install within frontend folder.
3. Update variables with your contracts addresses inside /frontend/components/instructionsComponent/index.tsx
4. Run npm run dev and open http://localhost:3000 with your browser to interact with the dApp.
