I've never seen the residual wax on the outside of the chain melt regardles of outside temps, but as hypothesized above, likely at least some is melting and resolidfying at the pin/plate interface as it bends around the chainring and cogs. Still not likely to cause any significant migration of contaminants I would guess.
