symmetric monoidal (∞,1)-category of spectra
A symmetric monoidal (weak) 2-category is a monoidal 2-category with a categorified version of a symmetry.
That is, it is a 2-category equipped with a tensor product 2-functor which satisfies all possible conditions for being commutative up to equivalence. In the language of k-tuply monoidal n-categories, a braided monoidal 2-category is a quadruply monoidal 2-category. As described there, this may be identified with a pointed 6-category with a single -morphism for . We can also say that it is a monoidal 2-category whose E1-algebra structure is refined to an E4-algebra structure.
