STBL functions as a next-generation stablecoin infrastructure platform, co-founded by Reeve Collins (founder of Tether) and Dr. Avtar Sehra (founder of Nivaura and Kaio). The platform is designed to power Ecosystem-Specific Stablecoins (ESSs), allowing banks, institutions, corporations, networks, and governments to issue branded stable-assets backed by real-world assets (RWAs).

The system utilizes a dual-token architecture that separates stable value from yield generation via two core primitives: USST and YLD. USST serves as a fully collateralized, dollar-pegged stablecoin intended for liquidity, payments, and settlement. In contrast, YLD represents the yield rights derived from the underlying reserve assets.

In traditional stablecoin models, issuers typically keep the reserve yield. STBL differs by enabling ecosystems to preserve and distribute this yield back to their communities. Users can deposit tokenized RWAs, such as Treasury Bills and money market funds, as collateral to mint USST while retaining exposure to the generated yield through YLD.

Through its Money-as-a-Service infrastructure, STBL facilitates the compliant issuance of ecosystem-specific stablecoins supported by customizable RWA collateral frameworks. The protocol aims to support transparency, redeemability, and institutional-grade on-chain finance.
