In this work, we address this gap by establishing theoretical results on the well-posedness of FSIDEs. In particular, we derive a generalized Grönwall inequality and present results on Ulam-Hyers stability (UHS). Moreover, we extend existing findings by incorporating both the Φ-Caputo fractional derivative and the p th moment, thereby unifying and generalizing current results in the literature.
