The problem LenDen solves

Owners of digital assets, especially those with NFTs or tokens on multiple blockchains, do not have a single, safe, and efficient platform where they can use their assets to get liquidity cross-chain. In addition, the complexity and differences in how different blockchains work make it even harder for users to use their assets across multiple chains. LenDen bridges the need for a seamless, user-friendly interface that makes the borrowing and lending process easier, so that users can get liquidity in a way that is simple and easy to understand.
We also provide users with cross chain credibility score which enables them to become a great and trusted user.
In case of failure to do loan repayment, we either keep the collateral or auction it off in our own application itself.

We have attached transaction screenshots in our repository.

Challenges we ran into

-Lack of Liquidity: Initially, we thought of maintaing the entire treasury by ourselves, but then shifted to lender-based system that we can give to the other users.

-Cross-Chain Complexity: The process of borrowing against assets spread across multiple blockchains is intricate, making it challenging for users to access loans which we integrated using Router Protocol seamlessly.

-Collateral Liquidation: In the context of the cross-chain lending and borrowing platform, collateral liquidation poses a challenge due to the inherent volatility and valuation complexities of digital assets, particularly NFTs. Accurate and fair valuation during liquidation, timely execution, and ensuring transparency while navigating through different blockchain protocols are significant hurdles.

-We had some techincal difficulties while working with router cross-chain contracts too.
