Payment UX is where the truth shows up. A stablecoin’s technical promise matters less than these five product details that determine real-world usability: On/off-ramp availability – Can users convert fiat to stablecoin and back within minutes, not days? Geographic coverage and banking partner depth dictate this. KYC friction – How much identity verification is required, and how often? One-time setup versus per-transaction checks create vastly different user journeys. Chargeback/finality – Are transactions reversible? For merchants, finality means no fraud clawbacks; for consumers, it means no safety net. Merchant tooling – Does the ecosystem offer plug-and-play checkout widgets, accounting integrations, and automatic settlement to fiat?

New rule: stablecoin issuers must hold 100% reserves in government securities with third-party custody. Impact chain: Issuers shift from commercial paper to T-bills, raising costs 15-20bp → Exchanges/payment processors upgrade compliance systems and pass costs downstream → Users face slower settlement (T+1 vs. instant) and higher on-ramp fees (0.2% → 0.4%) → Market consolidates around 2-3 compliant issuers, fragmenting by geography. Uncertainty: No clarity on enforcement for decentralized pools or cross-border transactions—implementation could be patchy.
