## Overview

This is a DeFi lending dApp: users connect a wallet, view deposit/borrow/collateral positions and market rates, then submit deposit, borrow, or collateral transactions. The React app reads lending and collateral state and invokes the corresponding contract interfaces. The tree names an interest-rate model, but the sampled app only initializes its interface; Solidity implementations were not sampled, so their internal calls and mechanics are not inferred.

Main entry points: [`App.js`](https://github.com/mlwithharsh/project---web3/blob/main/App.js) (dApp interface), [`LendingPool.sol`](https://github.com/mlwithharsh/project---web3/blob/main/LendingPool.sol) (Lending pool), [`CollateralManager.sol`](https://github.com/mlwithharsh/project---web3/blob/main/CollateralManager.sol) (Collateral manager)
