        abstract = {Decentralized Finance (DeFi) is reshaping tradi- tional financial systems by enabling trustless lending and borrow- ing through blockchain technology. Despite rapid growth, existing DeFi platforms face challenges such as smart contract vulner- abilities, oracle manipulation, liquidity instability, governance inefficiencies, and security risks including flash loan attacks. This paper presents VaultFi, a secure and governance-driven decentralized lending and borrowing platform designed to en- hance transparency, capital efficiency, and user participation. The system leverages Ethereum-based smart contracts to automate lending, borrowing, and liquidation processes while integrating decentralized price oracles for real-time asset valuation. DAO- based on-chain governance enables community-driven decision- making, and dynamic interest rate models optimize liquidity management. VaultFi also incorporates security mechanisms to mitigate reentrancy and oracle-related attacks. Performance metrics including Total Value Locked (TVL), borrowing activity, and user adoption are evaluated to assess platform effectiveness. The results demonstrate that VaultFi provides a scalable, trans- parent, and resilient framework for decentralized lending while promoting financial inclusion and sustainable DeFi growth.},
