The origin of matter in black hole-driven relativistic jets is unknown. In this work we set up a leptonicmatter injection model above accreting black holes based on electromagnetic cascades. The model assumes the existence of an electrostatic gap: a high energy particle acceleration region in the polar zone of the black hole magnetosphere. We calculate the gamma emission produced therein through the interactions of the accelerated particles with the magnetic field and the radiation field of the accretion disk. Those gamma rays propagate through the Poynting flux launched by the hole?s ergosphere and trigger the electromagnetic cascades which eventually load the flux with matter and reduce its magnetization. Finally, we simulate the cascades in detailusing a Monte Carlo code and calculate the magnetization along the jet.
