A theoretical understanding of a possible mechanism for synthesizing superheavy elements in the outer crust of magnetars is presented. We demonstrate that such a mechanism can be present whenever the baryon density in the outer crust of a neutron star reaches values around ${10}^{-2}$ ${\mathrm{fm}}^{-3}$. This scenario could be realized in magnetars with hypothetical large magnetic fields, $B\gtrsim {10}^{18}$ G. Under such conditions, the Coulomb lattice, formed by nuclei, enables a mechanism that synthesizes superheavy elements.
