  Majorana zero-modes in a superconductor are midgap states localized in the
core of a vortex or bound to the end of a nanowire. They are anyons with
non-Abelian braiding statistics, but when they are immobile one cannot
demonstrate this by exchanging them in real space and indirect methods are
needed. As a real-space alternative, we propose to use the chiral motion along
the boundary of the superconductor to braid a mobile vortex in the edge channel
with an immobile vortex in the bulk. The measurement scheme is fully electrical
and deterministic: edge vortices ($\pi$-phase domain walls) are created on
demand by a voltage pulse at a Josephson junction and the braiding with a
Majorana zero-mode in the bulk is detected by the charge produced upon their
fusion at a second Josephson junction.
