The emergence of Decentralized Finance (DeFi) has revolutionized traditional financial systems by introducing trustless, permissionless, and transparent platforms. However, lending and borrowing in the DeFi ecosystem face challenges like fluctuating collateral valuations, liquidity issues, and user inaccessibility. This study proposes a blockchain-based decentralized lending and borrowing platform leveraging smart contracts to facilitate secure, automated transactions. The platform integrates dynamic collateral management and liquidity optimization using a combination of IoT-based oracle data feeds and predictive models. A user-centric dashboard ensures transparency and accessibility, empowering users with actionable insights. Key findings validate the platform's scalability, security, and efficiency, advancing the broader goal of decentralized financial inclusivity.
