What it does
Save the user’s one-time funding profile — five multiple-choice compliance answers (employment status, source of funds, industry, income band, expected yearly funding volume). With a profile on file, wallet funding checkouts can skip the payment provider’s own identity questionnaire (the user’s existing KYC is reused). Ask the user each question conversationally and submit their answers; this is NOT a re-verification and no documents are involved. Answers can be updated any time by calling this again.
