PayPal, M0 and MoonPay officially launched the PYUSDx platform on September 9, providing businesses with infrastructure to create application-specific stablecoins backed by PayPal USD. Three early projects—Saturn, Concrete and Cap—went live at launch and have collectively processed more than $100 million in volume through the system.

PYUSDx functions as an issuance framework rather than a single stablecoin. Companies can configure tokens with distinct names, access controls, reward mechanisms, collateral rules and cross-chain support while using PYUSD as the underlying reserve asset. The approach aims to shorten the development timeline for customized dollar tokens from months to days, depending on technical needs and regulatory requirements.

How the Platform Operates

M0 supplies the programmable token infrastructure that allows issuers to select and adjust individual components instead of adopting a rigid design. MoonPay Digital Assets Limited handles issuance, onboarding and distribution of the custom tokens. PayPal contributes the connection to its PYUSD ecosystem. Paxos Trust Company remains the issuer of the underlying PYUSD stablecoin, which is fully backed by U.S. dollar deposits, U.S. Treasuries and similar cash equivalents and redeemable one-to-one for dollars.

The distinction between PYUSD and PYUSDx tokens is significant. Holders of custom tokens issued through the platform do not automatically receive the same direct relationship with Paxos that PYUSD holders maintain. Terms for each token depend on the participating company, MoonPay’s structure and the governing smart contracts. Users must review project-specific documentation for details on redemption and conversion rights.

First Projects and Processed Volume

Saturn, Concrete and Cap represent the initial wave of activity. Saturn operates USDat as a dollar-denominated token for settlement and liquidity within its Bitcoin-backed structured finance protocol, with roughly $65 million currently in circulation. Its staked version, sUSDat, provides exposure to a perpetual preferred equity instrument. Concrete introduced concUSD to support its on-chain vault systems that allocate and rebalance capital across decentralized finance venues. Cap migrated a portion of its cUSD to the platform for use in its covered credit system, where depositors, institutional borrowers and underwriters interact; cUSD has approximately $92 million in overall circulating supply.

The $100 million figure refers to combined processed volume linked to these projects rather than market capitalization, assets under management or revenue. No breakdown by individual token or activity type—such as transfers, settlements or minting—has been disclosed. The companies present the number as evidence that a shared infrastructure can support varied use cases in credit, vault management and settlement.

Limitations and Broader Context

PYUSDx tokens cannot currently be sent, received or used for payments inside the PayPal or Venmo applications. Eligible customers can buy, hold, transfer and sell PYUSD directly through those services, and businesses may use the original stablecoin for supported payments, but those capabilities do not extend to the custom tokens. Use cases for the new platform remain centered on external blockchain applications and specialized financial products.

Additional projects, including USD.AI and Fairblock, are expected to join, though no activation dates, supported networks or initial issuance amounts have been confirmed. The launch occurs against a backdrop of expanding stablecoin activity, with total circulation having surpassed $300 billion and global monthly transfer volume having exceeded $7.2 trillion earlier in 2026.

PayPal has positioned stablecoins as part of its wider payments strategy following substantial quarterly processing volumes. The PYUSDx framework offers an additional route to increase demand for PYUSD as reserve backing without PayPal operating every application built on top of it. Future growth will depend on adoption of the programmable features and reliable conversion between custom tokens and the underlying reserve asset. Each new token will require its own disclosures covering issuance, reserves, conversions, access controls and eligibility.
