The advancement of blockchain technology has created significant opportunities for transforming the financial sector, particularly banking. One of the most transformative applications of this technology is the smart contract—self-executing digital agreements that automatically enforce predefined conditions without the need for intermediaries. This study presents a systematic literature review of 10 academic publications published between 2020 and 2025 to evaluate the utilization of smart contracts in the banking sector. The analysis focuses on three main dimensions: technical implementation, regulatory compliance, and systemic risk implications. The findings indicate that smart contracts have been implemented in automated lending systems, decentralized identity verification (KYC), asset tokenization, real-time auditing, and blockchain-based payment infrastructures. Despite these advantages, adoption remains constrained by security vulnerabilities in contract code, scalability limitations, interoperability challenges, and regulatory uncertainty across jurisdictions. This study also proposes a conceptual experimental framework for evaluating smart contract performance, security robustness, and compliance readiness within banking environments. The results contribute to a more integrated understanding of how smart contracts can be adopted safely and sustainably in highly regulated financial ecosystems.
