Effective Field Theories (EFTs) offer a systematic way of parametrising small deviations from the Standard Model (SM) originating from new phenomena. In the top quark sector, by using the full potential of the second run of the LHC, the CMS Collaboration is able to perform precision measurements of well-studied top interactions as well as measure rarer top processes. This offers the exciting opportunity to probe new physics using the Standard Model Effective Field Theory (SMEFT) framework not only in pure top processes, but also in processes that connect the top quark with other sectors. This contribution summarises the latest measurements of SMEFT interactions in top quark processes in proton-proton collision data at a center-of-mass energy of $\sqrt{s} = 13$ TeV with an integrated luminosity of 138 fb$^{-1}$.
