In this paper, we study a variant of the state-dependent sweeping process with velocity constraint. The constraint $ {C(\cdot, u)} $ depends upon the unknown state $ u $, which causes one of the main difficulties in the mathematical treatment of quasi-variational inequalities. Our aim is to show how a fixed point approach can lead to an existence theorem for this implicit differential inclusion. By using Schauder's fixed point theorem combined with a recent existence and uniqueness theorem in the case where the moving set $ C $ does not depend explicitly on the state $ u $ (i.e. $ C: = C(t) $) given in [
