  In the scenario with a multiplicity of sectors which independently break
supersymmetry, multiplicity of goldstini are predicted. We propose a new
interpretation of the electron recoil excess at 2-7 keV observed in the XENON1T
experiment with very long-lived goldstini DM elastically scattering off the
electrons. The goldstini DM can be boosted by the late-decay of the other
nearly degenerate (long-lived) goldstini DM, with their tiny mass difference
being converted into kinetic energy of the lighter goldstini DM and neutrinos.
We show that viable parameter space can be found which can explain the excess
of electron recoil events around 2-3 keV recently reported by the XENON1T
experiment.
