# DeFi Guardian: Cross-Chain Financial Safety Net



**Description:**  

Navigating the complex world of DeFi across multiple blockchains has always been a challenging feat. DeFi Guardian emerges as a revolutionary solution, offering a seamless cross-chain liquidation protection, interest rate optimization system, and innovative debt-position NFTs, all empowered by Chainlink CCIP. Dive into a safer, smarter, and more integrated DeFi experience.



## 🌟 Features:



### 1. **Unified Liquidation Protection**:

   - Manage debt positions across varied protocols (e.g., Benqi on Avalanche, Compound on Polygon).

   - All liquidity is securely stored in one vault (default: Aave on Ethereum).

   - Smart "Automation" monitoring for each debt position. If a loan threatens to breach the liquidation threshold, our system instantly requests remedial action.

   - Effortless cross-chain communication: When the Ethereum vault gets the warning, it swiftly dispatches funds to cover the risky loan, preserving your financial health.



### 2. **Smart Interest Rate Optimizer**:

   - A built-in JavaScript function assesses interest rates across major lending protocols on all chains.

   - If you're overpaying on interest, the system autonomously strategizes to repay the loan, potentially refinancing it at a better rate.



### 3. **Debt-based Cross-Chain NFTs**:

   - Tokenize your debt positions as unique NFTs, allowing for transparent, tradeable, and flexible financial instruments.

   - Use NFTs as collateral in other DeFi protocols, enabling innovative financing and lending scenarios.

   - Benefit from fractional ownership and potentially create new markets for trading debt positions.



### 4. **Safe Wallet Liquidity Storage**:

   - Store your liquidity securely on a single chain with our "Safe Wallet" feature, ensuring a consolidated view and control over your funds.

   - Maintain financial sovereignty and optimize for gas costs and transaction efficiency.



### 5. **Customizable Infrastructure**:

   - By default, the Liquidation Protection Smart Contract (LPSC) is deployed on the `ethereumSepolia` chain.

   - For those who love to tinker, adjust the `defaultNetwork` property in the `hardhat.config.ts` to customize your main liquidity chain.



## 🚀 Getting Started:



1. **Deploy LPSC**: Start by deploying the Liquidation Protection Smart Contract on your liquidity chain.

2. **Set Up Automation**: For every chain where you've taken a loan, deploy the Monitor contract to keep a watchful eye on your debt ratios.

3. **Optional - Rate Checker**: Activate the JavaScript function to keep a check on prevailing interest rates, ensuring you always get the best deal.
