Here's what GENIUS accomplished on the regulatory front. The framework established federal guidelines specifically targeting payment stablecoins, with one crucial restriction at its core: issuers are prohibited from offering yield or interest returns simply for holding the stablecoin. This means Circle, as a USDC issuer, can't market a proposition like 'hold USDC and earn 4%' to users. The rule tightens compliance around how stablecoin programs structure their incentive mechanisms.
