PayPal (NASDAQ: PYPL), M0, and MoonPay have taken PYUSDx from a February preview to a live developer platform. The stack lets companies issue custom on-chain dollars that sit on top of PayPal USD (PYUSD), rather than forcing each team to build reserves, issuance, and liquidity from zero.
The public launch, announced September 9, 2026, already includes three live issuers—Saturn, Concrete, and Cap—with more than $100 million in processed volume. USD.AI and Fairblock are next in line.
M0 built the shared infrastructure.
MoonPay Digital Assets Limited issues the PYUSDx-layer tokens and holds the PYUSD that backs them. PYUSD itself remains a Paxos-issued product reserved with dollar deposits, Treasuries, and similar cash equivalents.
Tokens created on PYUSDx are not PayPal or Paxos products and are not usable inside PayPal or Venmo wallets.
The design is meant to give builders the product layer while the partners keep the monetary plumbing.
Teams can set names, symbols, reward routing, freeze controls, and other contract-level behavior, then mint against 1:1 PYUSD reserves.
Custom tokens are intended to stay convertible into PYUSD and other major dollar stables, so a new brand does not have to bootstrap an isolated market.
Official materials also point to multi-chain deployment, on-chain reserve checks, and later PayPal integrations if circulation grows.
The first live products show how different the “custom dollar” layer can look. Saturn used the rails for USDat, a settlement token tied to a Bitcoin-backed credit setup, and said the platform let it skip months of reserve and compliance work.
Concrete turned part of its vault liquidity into ConcUSD, a reward-bearing stable used inside its automated DeFi allocation stack.
Cap migrated a slice of cUSD onto PYUSDx so part of its covered-credit float would rest on PYUSD instead of more volatile DeFi liquidity.
M0 CEO Luca Prosperi’s line was that the product should belong to the builder; MoonPay’s Zach Kwartler argued the $100 million figure matters because the same issuance stack is already supporting credit, vault, and Bitcoin-linked products.
PayPal framed the move as a shift from selling a single stablecoin to making that coin extensible.
May Zabaneh, the company’s crypto general manager, said the next phase is less about the asset and more about what companies can build on it.
That is the competitive bet: as more banks and payment firms enter dollar tokens, a middle layer that abstracts developer risk could keep PYUSD relevant beyond PayPal’s own checkout and wallet surfaces.Limits remain.
Regulatory treatment of PYUSDx tokens varies by jurisdiction and sits with each issuer. Availability is not uniform. And users still have to understand they are holding a branded wrapper, not PYUSD itself. Even so, the September launch turns last winter’s framework into a working issuance rail with real volume and a public builder page at M0.
