PayPal’s new platform lets anyone issue a dollar backed by a dollar

MoonPay issues the token. It is backed by PYUSD. PYUSD is issued by Paxos and backed by actual dollars and Treasuries. Count the layers: there are two, and the law Congress passed last year describes one. Summary PayPal, M0, and MoonPay launched PYUSDx on September 9, a platform letting any business issue an application-specific stablecoin backed by PayPal USD. Three issuers are live at launch, Saturn, Concrete, and Cap, which the companies say have collectively processed more than $100 million, with USD.AI and Fairblock expected next. The structure has two layers: PYUSD is issued by Paxos Trust Company, a federally regulated national banking association, and backed by dollar deposits and Treasuries; PYUSDx tokens are issued by MoonPay Digital Assets Limited and backed by PYUSD. Tokens created on PYUSDx are not PayPal or Paxos products and cannot be sent, received, or used inside PayPal or Venmo. The GENIUS Act requires permitted issuers to back payment stablecoins one to one in named high-quality liquid assets, and a token backed by another stablecoin, issued by a different entity, is a structure the statute does not obviously address. Draw the plumbing and something odd falls out. PayPal, M0 and MoonPay went live on September 9 with PYUSDx, a platform that lets any business issue its own branded stablecoin without touching reserves, custody or redemption infrastructure. Three issuers launched with it. More than $100 million already processed between them. The pitch from all three partners is that the product layer should belong to whoever is building the product, and the monetary plumbing should belong to people who do plumbing. That is a good pitch and a sensible product. Now draw it. PYUSD is issued by Paxos, a federally regulated national banking association, backed by dollar deposits and Treasuries. Fine. Compliant. Boring, in the way a reserve asset should be. PYUSDx tokens are issued by MoonPay Digital Assets Limited. Their reserve asset is PYUSD. So the thing backing the second token is the first token. The GENIUS Act, signed in July 2025 and still being turned into regulations, tells you who may issue a payment stablecoin and what has to sit behind it. Cash. Insured deposits. Short-dated Treasuries. Repos against Treasuries. Money market funds holding those. It does not say anything about a stablecoin backed by a stablecoin, issued by someone else entirely. Nobody covering the launch has asked about it. It is worth asking now, while the rules are being drafted, instead of in eighteen months when they are not. What was actually built Three companies, three jobs. The details matter because they decide who is on the hook for what. M0 supplies the infrastructure.
