We present a new traversable wormhole explication of Einstein’s field equations supported by the profile of Einasto Dark Matter densities (Einasto in Trudy Inst Astrofiz Alma-Ata 51:87, 1965; PTarO 36:414, 1968; Astron Nachr 291:97, 1969) and global monopole charges along with semiclassical effects in the local universe as the galactic halo. The Einasto DM density profile produces a suitable shape function that meets all the requirements for presenting the wormhole geometries. The Null Energy Condition (NEC) is violated by the obtained solution with different redshift functions i.e. the Einasto profile representing DM candidate within the wormholes gives the fuel to sustain these wormhole structures in the galactic halo. Moreover, the reported wormhole geometries are getting asymptotically flat and non-flat depending only on the choices of redshift function whereas all the wormhole structures are maintaining their balance of equilibrium under the action of different forces.
