Asset tokenization is transforming financial landscapes, yet the development of coherent public policy has not kept pace with technological innovation, leaving a critical need for a structured regulatory guide. This paper addresses this gap by developing a comprehensive conceptual framework for asset tokenization regulation. The study employs a Systematic Literature Review (SLR) guided by the PRISMA protocol. A final corpus of 65 publications was identified through a structured search of the Scopus, Web of Science, and ScienceDirect databases and analysed using a hybrid thematic synthesis method that combined BERTopic for computational theme discovery with subsequent qualitative refinement. The principal finding of this research is a conceptual framework comprising seven core, interconnected categories: (1) Token Classification and Definitions; (2) Tokenization Types and Methodologies; (3) Custody and Transfer Risks; (4) Compliance; (5) Stablecoins: Regulatory and Governance Structures; (6) Decision-Making Frameworks and Processes; and (7) Jurisdictional Regulatory Aspects. This framework provides an evidence-based resource for policymakers to design holistic regulatory strategies and foster responsible innovation, while also serving as a structured foundation for future academic research in blockchain technology and its applications in business information processing.
