In this work, we assign the tetraquark state for $Y(4230)$ resonance, andinvestigate the mass and decay constant of $Y(4230)$ in the framework of SVZsum rules through a different calculation technique. Then we calculate thestrong coupling $g_{Y J/\psi f_0}$ by considering soft-meson approximationtechniques, within the framework of light cone sum rules. And we use strongcoupling $g_{Y J/\psi f_0}$ to obtain the width of the decay $Y(4230)\to J/\psif_0(980)$. Our prediction for the mass is in agreement with the experimentalmeasurement, and that for the decay width of $Y(4230)\to J/\psi f_0(980)$ iswithin the upper limit.
