The fast development of blockchain and financial technology (FinTech) has drastically changed the investment environment, especially when it comes to mutual fund investments. Blockchain technology has improved transparency, security, and trust, while digital platforms, mobile applications, and online payment methods have streamlined investing procedures. With a focus on working professionals, this study attempts to investigate how FinTech and blockchain affect mutual fund investment decisions. The goal of the study is to comprehend how investor knowledge, convenience, risk perception, and decision-making behaviour are impacted by technology-driven platforms. The results show that although blockchain-based features have boosted investor confidence by guaranteeing data security and transaction transparency, FinTech platforms have improved accessibility and convenience of investment. According to the study’s findings, FinTech and blockchain are essential for encouraging wise and effective mutual fund investing choices in the digital era.
