While all seven of Voldemort's Horcruxes were destroyed by different wizards – and, obviously, he didn't destroy any himself – this Quora user points out that the destruction of each Horcrux was ~made possible~ by Voldemort. Five of the Horcruxes (the diary, the locket, the cup, the ring, and Nagini) were destroyed using Basilisk venom – either from the fangs of the Basilisk itself, or using the sword of Gryffindor, which was impregnated with the venom. Voldemort was the one who opened the Chamber of Secrets and allowed access to the Basilisk in the first place. The diadem was destroyed by the Fiendfyre conjured by Crabbe in the Room of Requirement – a spell taught to him by Voldemort's Death Eaters. And the final Horcrux, Harry, was destroyed by Voldemort's own killing curse. Sorry, Voldy.
