ABSTRACT: Blockchain technology is revolutionizing financial systems by enabling secure, transparent, and decentralized transactions. The emergence of cryptocurrencies and decentralized applications (dApps) has facilitated the development of financial systems independent of traditional intermediaries. However, challenges such as high gas fees, limited scalability, and smart contract vulnerabilities persist. This paper explores how existing blockchain technologies have tackled these issues and proposes an approach for building more efficient, secure, and user-friendly decentralized finance (DeFi) applications. With a focus on Ethereum-based smart contracts and tools like MetaMask, Solidity, and Hardhat, this study highlights both the opportunities and the technical gaps present in current implementations. The goal is to enhance user experience, security, and scalability in DeFi systems.
