Yaramolu, Leela Sri Kalyan Gowtham (2025) Smart contracts in Fintech: Revolutionizing financial transactions. World Journal of Advanced Research and Reviews, 26 (1). pp. 4149-4159. ISSN 2581-9615

Smart contracts are revolutionizing financial transactions by automating contractual agreements through blockchain technology, eliminating the need for intermediaries while enhancing security, efficiency, and accessibility across the financial sector. These self-executing protocols operate on predefined conditions, automatically verifying and executing terms without human intervention. Built on distributed ledger technology, smart contracts inherit key blockchain characteristics, including immutability, transparency, and cryptographic security, creating auditable transaction trails that significantly reduce fraud potential. While offering substantial benefits like reduced operational costs, accelerated settlement times, and enhanced financial inclusion, smart contracts face critical challenges, including security vulnerabilities, regulatory uncertainty across jurisdictions, and scalability limitations. Ongoing developments in security approaches like formal verification and specialized auditing firms are addressing vulnerability concerns, while progressive regulatory frameworks are emerging in forward-thinking jurisdictions. The future integration landscape is being shaped by advancements in cross-chain interoperability, Oracle integration for real-world data feeds, layer-2 scaling solutions, AI-enhanced optimization, and hybrid systems combining traditional legal contracts with automated execution. As blockchain technology matures, smart contracts are positioned to fundamentally transform financial infrastructure, contingent upon the continued evolution of security practices and regulatory frameworks.
