A Systematic Review on the Application of Artificial Intelligence in Decentralized Finance

This study presents a comprehensive systematic review of Artificial Intelligence (AI) applications in Decentralized Finance (DeFi), emphasizing AI’s pivotal role in mitigating the vulnerabilities and operational complexities inherent in permissionless financial systems. By systematically analyzing 39 peer-reviewed studies from major scholarly databases, the review identifies five dominant application domains: fraud detection, smart contract security, market prediction, credit risk assessment, and decentralized governance. It examines the diverse range of AI methods spanning machine learning, deep learning, graph neural networks, and reinforcement learning—and evaluates their comparative performance and limitations. The findings reveal that AI not only enhances DeFi’s transparency, trust, and efficiency but also underpins emerging capabilities such as autonomous governance and adaptive market mechanisms. Persistent challenges including data scarcity, cross-chain generalization, interpretability, and scalability—underscore the need for robust, explainable, and ethical AI solutions. The review concludes that AI constitutes a foundational enabler for secure, transparent, and resilient decentralized financial ecosystems, and outlines critical future research directions for integrating trustworthy intelligence into the evolving DeFi landscape
