In this study, we investigate the imprints of CP violation in certain η muonic decays that could arise within the Standard Model effective field theory. In particular, we study the sensitivities that could be reached at REDTOP, a proposed η facility. After estimating the bounds that the neutron EDM places, we find still viable to discover signals of CP violation measuring the polarization of muons in ημ+μ decays, with a single effective operator as its plausible source.
