Generalised Parton Distributions (GPDs) are a key point of the EIC physics case as they encode the 3D structure of hadrons. Contrary to the usual Parton Distribution Functions (PDFs) they have to obey a certain number of theoretical properties coming from first principle considerations. Both extraction and modelling of GPDs must therefore fulfil these criteria, especially at a time when experimental uncertainties are expected to de significantly reduced. We will present in this talk a approach based on Lightfront wave functions which allows one to fulfil a priori all the theoretical constraints required to get GPDs (models or extractions) consistent with all known theoretical constraints.
