In memory of

Dmitry Tolkachev

July 3, 1988 – June 20, 2019

OptiMargin family is currently mourning the tragic death of one of our founders, Dmitry Tolkachev, who
passed on Thursday due to tragic accident. Dmitry was involved in every aspect of development, was one
of the founders of OptiMargin and was nothing short of a genius. He is survived by his wife, brother, and
parents. He is and will be sorely missed.
