SNARKs for some standard cryptographic primitives tend to be plenty designed with SNARK-unfriendly operations such as XOR. Previous protocols such as [GW20] worked around this problem by the introduction of lookup arguments. However, these protocols were only appliable over the same circuit. RapidUp is a protocol that solves this limitation by unfolding the grand-product polynomial into two (equivalent) polynomials of the same size. Morevoer, a generalization of previous protocols is presented by the introduction of selectors.
