This project is a decentralized finance (DeFi) lending and borrowing platform that enables users to supply and borrow multiple crypto assets such as ETH, USDT, and DAI through non-custodial smart contracts.

Users can deposit supported assets into liquidity pools, where their funds become available for borrowers. In return, depositors receive protocol-generated rewards based on pool utilization.
Borrowers can use their deposited assets as collateral and borrow other supported tokens, with borrowing limits determined by the platform’s collateralization ratio and real-time asset pricing.

To protect the system from under-collateralized positions, the platform includes a liquidation mechanism. When a user’s collateral ratio falls below the required threshold, third-party liquidators (including bots) can repay a portion of the borrower’s debt and receive part of their collateral as an incentive. This liquidation process helps maintain the health and stability of the protocol.

All core financial logic, including deposits, borrowing, interest accrual, collateral management, and liquidation, is handled on-chain via smart contracts, ensuring transparency and verifiability.
The frontend offers a user-friendly dashboard with real-time data, wallet integration, and clear position tracking.
