The purpose of this study is to investigate and analyze the determinants of using digital payment platforms, as well as their implications for behavior and intention to use for some people who used mobile payment in Jakarta, Indonesia. This study uses primary data obtained by distributing online questionnaires to applicants who adopted and implemented the mobile payment platforms. Performance expectancy (PE), hedonic motivation (HM), facility condition (FC), social influence (SI), price value (PV), and perceived technical security (PTS). Platform trust in platforms (TP) as an intervening variable, plus behavior intention to use (BI) as a dependent variable. To conduct all the data, a multi-regression linear approach is used, along with some hypothesis tests. A total of 210 respondents as a target were reached through Google Drive forms questionnaires. The empirical findings revealed that PE and HM have significant effects on platform trust. While FC, SI, PV, and PTS do not influence TP. Further, SI, HM, and TP have a significant effect on the variable BI. Likewise, PE, FC, PV, and PTS have no effect on the dependent variable of BI. Eventually, Trust in Platforms is the intervening construct of SI, HM, and PTS on Behavior Intention to use. Meanwhile, the others, like PE, FC, SI, and PV, don't have any influence on BI through TP. The study contributes to the literature by documenting the determinants of Trust in Platforms as well as the implementation of BI. It is expected to make a significant contribution since similar research is rarely conducted in Indonesia's context. It mitigates the frontier literacy by providing the empirical evidence and recommending that the topic needs more exploration and development on the platforms of mobile payments. To provide a recommendation to accelerate the growth of mobile devices. The findings could be appreciated from divergent perspectives. From a government perspective, it might be insightful to explore the utilization of developing convenient discretion of trust using a platform more professionally and responsibly to offer an acceptable device. The results might be used by the companies' CEOs who want to compile future policies that focus on digital payments that have been rapidly spreading in recent years. This study has some limitations. First, we considered only the 210 respondents. Second, additional variables such as biographic factors are needed to obtain deeper results. Third, expand the research area to get more diverse respondents who carry out many digital devices.
