Decentralized Finance (DeFi) lending platforms have gained significant traction, with over $30 billion worth of cryptocurrencies locked up in their systems. Among the popular platforms are Aave, Nolus, and Compound. Aave offers flash loans, enabling users to borrow without collateral, while Nolus introduces a leasing-like system with lower collateral requirements. Compound provides dynamic interest rates based on supply and demand. Despite their success, the DeFi lending space faces challenges, including high over-collateralization requirements and limited accessibility due to blockchain restrictions. As mainstream investors become more interested in DeFi lending, these platforms will play a crucial role in shaping the future of decentralized finance.
