PayPal, M0 and MoonPay officially launched the PYUSDx custom stablecoin platform on Sept. 9 with three active projects that the companies said have collectively processed more than $100 million. Summary PYUSDx lets businesses issue customized stablecoins backed by PayPal USD through modular token infrastructure services. Saturn, Concrete and Cap launched tokens that collectively processed more than $100 million already combined. MoonPay Digital Assets issues PYUSDx tokens while Paxos separately issues the underlying PYUSD stablecoin directly. PYUSDx tokens currently cannot be sent, received or used inside PayPal and Venmo payment applications. USD.AI and Fairblock are expected to join after the first three platform projects launched publicly. PYUSDx allows businesses to issue application-specific stablecoins backed by PayPal USD. Companies can give their tokens separate names and configure access restrictions, reward distribution, collateral policies and cross-chain availability. The partners initially announced the framework in February. As crypto.news previously reported, PayPal and MoonPay introduced the custom stablecoin infrastructure as a way for developers to create branded digital dollars without independently building issuance and liquidity systems. M0 developed the programmable token infrastructure used by PYUSDx. Its system lets issuers configure individual components instead of accepting a fixed stablecoin model. MoonPay contributes issuance, onboarding and distribution services. PayPal supplies the ecosystem connection through PYUSD. The arrangement extends the role of PayPal’s stablecoin beyond direct payments by allowing other financial applications to use it as an underlying reserve asset. The companies said the structure can reduce the time required to create a customized stablecoin from several months to days. That remains a company claim and will depend on the project, its technical requirements and applicable regulatory approvals. PYUSDx is not a stablecoin itself. It is an issuance framework supporting separate digital tokens. Each participating company can configure a token for its own settlement, credit, treasury or decentralized-finance use case. Three PYUSDx projects bring more than $100 million Saturn, Concrete and Cap are the first projects operating through the platform. M0 said the three businesses brought more than $100 million in combined processed volume at launch. The disclosed figure refers to activity connected with those projects rather than the market capitalization of PYUSDx. Saturn uses the system for USDat, a dollar-denominated token designed for settlement. Concrete launched concUSD for its on-chain vault infrastructure, while Cap introduced cUSD as the native dollar asset for its credit platform. The projects retain control over branding and certain operating rules. They can also determine how returns or incentives are distributed, subject to their chosen structures and applicable laws. The companies have not provided a breakdown showing how much of the reported $100 million came from each project. They also have not disclosed whether the figure represents transfers, settlement volume, minting activity or another measure across every participating token. The absence of a detailed breakdown means the figure should not be treated as the platform’s revenue or assets under management. It is a reported measure of processed activity supplied by the companies behind the launch. USD.AI and Fairblock are expected to integrate later. Neither project disclosed a confirmed activation date in the launch materials. Their participation should therefore be treated as planned until their tokens become operational through the platform. PYUSDx tokens are not issued directly by PayPal MoonPay Digital Assets Limited issues the custom tokens created through PYUSDx. PayPal and Paxos do not directly issue those derivative tokens, despite their connection to the PYUSD reserve asset. Paxos Trust Company issues the underlying PYUSD stablecoin. PayPal’s official disclosure says PYUSD is redeemable one-to-one for U.S. dollars and backed by dollar deposits, U.S. Treasuries and similar cash equivalents. Moreover, Paxos publishes information about those reserves through its transparency page. The issuer provides monthly reserve reports and third-party attestations covering the assets supporting PYUSD. The distinction between PYUSD and a PYUSDx token matters for users assessing issuer and redemption risk. Holding a custom token does not necessarily create the same direct relationship that a holder of Paxos-issued PYUSD may have with its issuer. A PYUSDx token’s terms can also depend on the participating business, MoonPay’s issuance structure and the smart contracts governing conversions. Users must examine each token’s documentation rather than assuming that every project offers identical redemption rights. Regulatory treatment may vary between jurisdictions and applications. A token used for lending, rewards or restricted settlement could face different rules from a stablecoin used mainly for payments. PayPal and Venmo do not support PYUSDx tokens PYUSDx tokens cannot currently be sent, received or used for payments inside PayPal or Venmo. Those restrictions separate the new platform from the consumer-facing PYUSD services available through PayPal’s applications. Eligible PayPal customers can buy, hold, transfer and sell PYUSD. Businesses can also use the original stablecoin for supported payments. Those functions do not automatically extend to USDat, concUSD, cUSD or future PYUSDx assets. The limitation means PayPal’s brand and underlying stablecoin should not be interpreted as a guarantee that every custom token will work across PayPal’s payment network. The platform’s immediate use cases remain centered on external blockchain applications and specialized financial products. PayPal has continued to expand the original stablecoin’s blockchain reach. In related coverage, PYUSD became available through Polygon’s Open Money Stack, providing businesses with additional payment, compliance and fiat-conversion infrastructure. The company has also positioned stablecoins as part of its wider payments strategy. As crypto.news reported, PayPal made stablecoins a corporate growth priority after processing $486.4 billion in quarterly payment volume. PYUSDx gives PayPal another way to increase demand for its stablecoin without directly operating every application built around it. If participating projects grow, they may require more PYUSD as backing. The partners have not published targets for future issuance or reserve demand. What happens next for PYUSDx The next confirmed stage is the planned addition of USD.AI and Fairblock. The companies have not announced precise launch dates, supported networks or initial issuance amounts for either integration. PayPal, M0 and MoonPay may also add more businesses seeking customized settlement assets. Any new token will require its own disclosures covering issuance, reserves, conversions, access controls and user eligibility. More detailed reporting on the first three projects would help establish what the $100 million figure represents. Reserve verification will also be important because users need to distinguish the amount of underlying PYUSD from transaction volume generated by the custom tokens. PYUSDx therefore enters operation as an infrastructure layer rather than a direct replacement for PYUSD. Its early progress will depend on whether businesses adopt its programmable features and whether holders can reliably convert custom tokens into the underlying reserve asset.
