The PayFi Stack: A Blueprint for On‑Chain Finance
Modeled after the OSI framework, @Huma Finance 🟣 ’s PayFi Stack introduces a modular, interoperable foundation for the future of finance.
Spanning six key layers—from transaction routing on Solana and Stellar, to compliance, custody, credit, and settlement—this architecture standardizes blockchain-based payment systems on a global scale.
Builders, institutions, and innovators now have a common framework to launch DeFi-native lending, remittance products, and more.
This isn’t just infrastructure—it’s the “currency internet” in motion: scalable, secure, and built for global inclusion.
