Onboarding friction for new crypto payment rail integration

We're exploring integrating a new crypto payment rail to broaden our acquiring options, specifically for smaller, cross-border transactions. The KYC/KYB requirements from these new providers seem disproportionately heavy for the transaction sizes we're anticipating. Has anyone successfully streamlined the onboarding process with multiple crypto PSPs, especially concerning repetitive documentation for similar services? We're trying to avoid a full legal review for each new integration.
