LenDen is a cross-chain liquidity platform that enables owners of digital assets, especially those with NFTs or tokens on multiple blockchains, to use their assets to get liquidity cross-chain. The platform provides a seamless, user-friendly interface that makes the borrowing and lending process easier, allowing users to get liquidity in a simple and easy-to-understand way. LenDen also provides users with a cross-chain credibility score which enables them to become trusted users. In case of failure to do loan repayment, the platform either keeps the collateral or auctions it off. Built at Unfold 2023 hackathon, this project won First Place in the Router Protocol track by leveraging Router cross-talk contracts for seamless cross-chain functionality.
