Payy is a non‑custodial on‑chain banking platform that enables fee‑free stablecoin transfers via privacy‑preserving payment links usable in any messaging app. It combines built‑in fiat on‑ramps, a Payy Card for point‑of‑sale spending, and a zero‑knowledge proof layer that hides transaction metadata while remaining auditable. The system also offers a forthcoming guardian module for multi‑factor account recovery and developer APIs for integration.

Problem
Stablecoin transactions on most public blockchains expose full payment details, incur gas fees, and can be subject to account freezes or censorship, limiting their utility for private, low‑cost everyday payments. Users also lack a unified, non‑custodial interface that combines fiat on‑ramps, stablecoin storage, and seamless peer‑to‑peer transfers.
Solution
Payy delivers an on‑chain banking platform that natively operates with stablecoins while embedding privacy‑preserving zero‑knowledge (ZK) proofs. Users generate payment links that can be shared through any messaging app, enabling instant, fee‑free transfers without exposing transaction metadata. The wallet is non‑custodial, so funds remain under the user’s control and cannot be frozen by a third party. Integrated fiat ramps and a Payy Card extend stablecoin usability to traditional merchant payments. A forthcoming guardian system will add multi‑factor account recovery and protection against takeover attempts.
Target Audience
The primary users are privacy‑conscious cryptocurrency holders, freelancers, and merchants who need fast, fee‑free stablecoin payments, as well as developers building DeFi or Web3 services that require integrated, non‑custodial payment primitives.
