How USAD Works
USAD is a next‑generation, ERC‑4626‑compliant, USD‑pegged digital asset designed for everyday utility and institutional‑grade transparency. It is issued against a diversified reserve basket and operates with clear, auditable on‑chain mechanics so anyone can verify supply and flows. Whether you are a retail user or an integrator, USAD aims to deliver a fast, predictable, and secure experience across popular EVM networks.
Beyond on‑chain interoperability, USAD emphasizes practical usability. Daily circulation figures and periodic attestations help you assess risk quickly, while standards‑based vault logic improves compatibility with wallets, exchanges, and DeFi protocols.
Vault and Issuance Flow (ERC‑4626)
USAD is implemented as an ERC‑4626 tokenized vault. Depositors provide reserve assets (e.g., BTC, USDC, USDT, GXAU) to the vault, and in return receive USAD shares representing their claim on the underlying basket. Redemptions burn USAD shares and withdraw the corresponding amount of reserve assets. The vault mechanics are standards‑based and interoperable with wallets and DeFi protocols.
