The full version of the QCD light-cone sum rule method is applied to tetraquarks containing a single heavy b or c quark. To this end, investigations of the strong vertices XbXb\ensuremathρ and XcXc\ensuremathρ are performed, where Xb=[su][bd] and Xc=[su][cd] are the exotic states built of four quarks of different flavors. The strong coupling constants G_XbXb\ensuremathρ and G_XcXc\ensuremathρ corresponding to these vertices are found using the \ensuremathρ-meson leading- and higher-twist distribution amplitudes. In the calculations, Xb and Xc are treated as scalar bound states of a diquark and antidiquark.
