A rapid change in the financial industry has been brought about by the development of financial technology (fintech), which has offered convenience, efficiency, and increased accessibility to financial services. There is, however, a darker side to fintech as voltaic money laundering has emerged alongside these benefits. Through fintech platforms, funds are illicitly transferred and concealed through voltaic money laundering. There are several aspects of solar-powered money laundering discussed in the paper, including client differentiation, rapidity of business deals, currency consideration, worldwide transactions, monitoring gaps, disingenuous political behavior, tax avoidance, and a lack of accountability are some of the aspects discussed in the paper. Fintech’s role in enabling illicit financial activities is explored in each aspect. Moreover, the study proposed potential areas for future research on voltaic money laundering and identified limitations in current understandings. There are a number of issues in this regard, including data limitations, fintech’s constantly evolving nature, jurisdictional concerns, technological developments, regulatory implications, as well as the socioeconomic effects of voltaic money laundering. This research contributes to the existing literature on financial crime through its examination of the dark side of fintech and offers insights for policymakers and regulators seeking to combat illicit financial activities within this domain. In the digital age, it is extremely important to understand and address voltaic money laundering.
