Beyond TWINT, Stablecoins, and CBDCs: Enter PayFi (September 2025)

The BIS and regulators from EU to Switzerland are openly shaping how programmable money should work. It is time to look and consider PayFi, short for Payment Finance, because it is quietly emerging as the connective tissue that could bring these initiatives together. I want to highlight why PayFi matters, where it fits, and what challenges it still faces.

PayFi is the emerging infrastructure that merges payments with decentralized finance (DeFi). Instead of treating payments as static transfers, PayFi turns them into programmable, real-time, and finance-enabled flows. It grew out of blockchain and DeFi experiments, and is now being accelerated by businesses demanding faster settlement, capital efficiency, and automation. Early ecosystems such as Huma Finance, Arf Financial, and integrations by Visa and PayPal show that PayFi is becoming more than a niche. What makes it novel is not just speed, but the ability to program money itself: To split a payment between multiple parties, hold it in escrow until conditions are met, stream it over time like a salary, or even embed financing by turning invoices into instant liquidity. In short, every transaction can become an asset that works immediately.

CBDCs aim to provide public digital cash, Stablecoins already serve as practical settlement assets, and bank-led apps and cards dominate consumer payments. PayFi is less a rival than an aggregator and complement: It can route payments over stablecoins today, CBDCs tomorrow, or tokenised deposits when and if they arrive, and add the programmability none of the others natively deliver. In some contexts, such as cross-border B2B settlement, it clearly winningly competes with legacy rails by reducing costs and latency. PayFi is the orchestration layer beneath the user interfaces people already trust.

Real-time settlement frees working capital. Embedded financing lowers barriers for small firms and creators. Programmability automates compliance, tax, and complex value chains. Lower fees and cross-border reach can make global commerce more inclusive.

Adoption won’t be automatic. While regulators and the BIS welcome programmability and tokenisation, they remain cautious of private Stablecoins. Interoperability and standards must mature. Merchants expect the dispute rights and fraud protection that card networks perfected. And entrenched players may resist where fee income and data control are at stake.

By sitting between money formats and user apps, PayFi does not replace CBDCs, Stablecoins, or digital payment apps. It connects them into a flexible, capital-efficient, and programmable settlement fabric for the digital
