  We define a map from the skein module of a cusped hyperbolic 3-manifold to
the ring of Laurent series in one variable with integer coefficients that
satisfies two properties: its evaluation at peripheral curves coincides with
the Dimofte--Gaiotto--Gukov 3d-index, and it factors through the 3d-quantum
trace map associated to a suitable ideal triangulation of the manifold. The map
fulfills a supersymmetry prediction of mathematical physics and is part of a
conjectural 3+1 dimensional topological quantum field theory.
