Raycash, a Zama spin-off, has opened a private Ethereum beta for confidential USDC payments and yield on idle balances. The company says more than 75,000 people have joined the waitlist, with access opening in stages ahead of a wider release.

The application wraps the dollars users already hold into confidential tokens rather than asking them to trust a newly issued stablecoin.

How the Confidential Payments Model Works

Raycash describes itself within Zama's ecosystem as an onchain payments product built around private digital dollars, with cards and banking-style rails part of the product vision. The company's website is at raycash.xyz.

At launch, the app supports USDC. Users wrap their USDC 1:1 into ERC-7984 confidential tokens, keeping balances and payment amounts encrypted on a public chain while settlement still occurs onchain. According to the project, unwrapping is permissionless, meaning the underlying dollars can move back out without a new issuer.

Raycash says wallets are self-custodial and that the confidential tokens carry no freeze or seize functions at the token layer. That claim sits alongside a separate risk category: exchange freezes following flagged deposits remain a real possibility, as recent warnings over discounted USDT and Binance account freezes have shown. Users can still grant view access to named parties, such as an accountant or auditor.

Deposits can arrive by bank transfer, card, or stablecoin, and withdrawals can return to bank accounts. Payment links handle sending, requesting, and receiving, while network fees are managed in the background so users do not need to hold ETH for gas. That last detail removes a familiar onboarding hurdle: without fee abstraction, users would have to acquire ETH before moving their own dollars.

Idle balances can earn yield through Morpho from inside the app, and a private spending card branded Raycard is in development.

"People shouldn't have to choose between the benefits of stablecoins and keeping their financial information confidential," Raycash CEO and co-founder Valerio Leo said. "We don't ask anyone to trust a new stablecoin: we take the dollars people already use and make them private, and they can move back out whenever they want."

Why Encrypted USDC Matters on a Public Chain

Every ordinary ERC-20 transfer publishes balance, amount, and counterparty to anyone with a block explorer. Confidential USDC (cUSDC) keeps the same dollar token but encrypts amounts and balances by default.

The ERC-7984 standard for confidential fungible tokens, drafted on ethereum.org, retains an account-based model in which transfer amounts and balances become confidential pointers rather than public integers. Zama's product pages state that the interface mirrors ERC-20, with encrypted handles replacing visible values and access control covering authorized viewers. That is the stack Raycash is productizing for payments — the company is not minting a competing dollar, but wrapping an existing one. The design inverts the usual default: instead of full transparency with privacy as an add-on, balances stay hidden until a holder grants a named viewer access.

Where Morpho Yield Fits

Confidential dollars need somewhere to work when they sit idle. In June 2026, Zama launched a Morpho vault curated by Steakhouse Financial for confidential USDC deposits, and later said that first vault grew from zero to more than $40 million in shielded TVL within seven weeks. On September 15, the arrangement expanded to 16 confidential Morpho vaults across five curators and five asset classes, alongside confidential swaps. In Morpho's vault structure, curators steer where deposited funds are supplied, which places the curator role at the risk-management layer of the yield arrangement.

Raycash's Morpho earn feature sits on the same privacy-plus-yield path but lives inside a payments app rather than a protocol dashboard. The beta proposition is straightforward: users can send encrypted dollars and, when they are not sending, earn yield without broadcasting position size on a public explorer.

What the Private Beta Signals — and What It Does Not

The recurring question raised by the launch is what confidentiality at the amount layer actually changes when a stablecoin payment sits on a public chain. It does not alter the dollar claim itself; USDC's issuer relationship and reserve arrangements remain upstream of the wrap. What changes is the visibility tax. Public balances and public payment amounts are a genuine inconvenience for payroll, peer transfers, and anyone who does not want a wallet address to become a full spending diary. Encrypted amounts address that inconvenience without inventing a new peg.

The failure mode to keep in view is trust migration rather than the peg story. Users still have to trust the app's fee handling, the wrap and unwrap path, the Morpho yield routing, and the no-freeze claim at the token layer. A waitlist is not proof of active spending, and a private beta does not establish that accountants, banks, or regulators will accept selective disclosure as sufficient. Those tests lie ahead of the invite list.

Unknowns remain. Public materials so far do not specify how many waitlist users are live in the beta, how much USDC has been wrapped, or when Raycard will ship. Broader stablecoin support is promised after USDC, though the launch materials carry no dated schedule.

The peg promise remains the same question it has always been. What this launch addresses is whether everyday dollar payments on Ethereum can hide the amounts without asking users to leave the dollar they already use.
