  We construct by direct computation holographic presentations of
supertranslation vacua given a set of supermomenta. To do this, we make use of
two-dimensional dual models recently discovered by the author, which encode
soft dynamics of gravity at leading order. In particular, the two-dimensional
models are used to define soft currents, of which the supertranslation vacua
are eigenstates. Operationally, the eigenstates are determined by the bare
vacuum state dressed by exponential operators that generalize the dressing due
to Faddeev and Kulish.
