  "abstract": "In this article we study the structure of the $\\mathcal{N}=2$ abelian higher-spin cubic $(\\mathbf{s_1}, \\mathbf{s_2}, \\mathbf{s_2})$ vertices and the corresponding $\\mathcal{N}=2$ higher-spin supercurrents, introduced in arXiv:2408.00668. These interactions are possible only for $\\mathbf{s_1} \\geq 2 \\mathbf{s_2}$. Conserved supercurrents are constructed as descendants of the \\textit{principal supercurrent}, which is uniquely characterized by simple differential conditions and admits an explicit representation in terms of $\\mathcal{N}=2$ higher-spin super-Weyl tensors. We derive the analytic form of the abelian vertices and identify the corresponding analytic higher-spin $\\mathcal{N}=2$ supercurrents. We show that the vertex structure is fully determined by the analytic supercurrents $J^{++}_{α(s-1)\\dotα(s-1)}$, $J^+_{α(s-1)\\dotα(s-2)}$, and $\\bar{J}^+_{α(s-2)\\dotα(s-1)}$. The analytic form of the vertices provides a simple framework for analyzing their component structure. As an example, we explore the component content of such interactions on the Bel--Robinson diagonal. Using the superfield inverse Noether procedure, we study higher-spin gauge transformations for the $\\mathcal{N}=2$ vector multiplet associated with the $(\\mathbf{s}, \\mathbf{1}, \\mathbf{1})$ interaction. In the rigid limit, for odd $\\mathbf{s}$ these transformations reduce to the $\\mathcal{N}=2$ superspace generalization of zilch-type higher-spin symmetries.",
