With the rapid development of blockchain and the increasing computing power, the realization of the metaverse has become possible. However, there are not yet well-regulated and standardized industry standards for the metaverse, thus various financial crimes have been bred in many metaverse projects: scams, code exploits, wash trading, money laundering, illegal services, shops, etc. For this reason, it is urgent to categorize the crimes that exist in the metaverse ecosystem and summarize the corresponding governance. In this paper, we first describe the background and applications of the metaverse. Next, we present detailed case studies on different types of crimes in the metaverse, and summarize the metaverse’s current regulatory measures, related governance. Finally, we suggest possible directions and recommendations for the development of relevant measures and governance. The overview of this paper is expected to help readers gain a deeper understanding of the financial threats in the metaverse.
