Raycash, a Zama spin-off, opened a private Ethereum beta for Raycash confidential USDC payments and idle-balance yield. The company says more than 75,000 people joined a waitlist. Access opens in stages before a wider release.
That is the plain read. The app wraps dollars people already hold into confidential tokens. It does not ask users to trust a new stablecoin.
How Raycash Confidential USDC Payments Work
Raycash lists itself in Zama’s ecosystem as an onchain payments product built around private digital dollars. Cards and banking-style rails sit in the product story. The company site is at raycash.xyz.
At launch, the app starts with USDC. Users wrap that USDC 1:1 into ERC-7984 confidential tokens. Balances and payment amounts stay encrypted on a public chain. Settlement still happens onchain. Unwrap is permissionless, the project says. The underlying dollars can move back out without a new issuer.
Wallets are self-custodial, Raycash says. The confidential tokens carry no freeze or seize functions at the token layer. That claim sits next to a different risk class. Exchange freezes after flagged deposits remain real, as recent discount USDT Binance freeze warnings showed. Users can still grant view access to named parties such as an accountant or auditor.
Deposits can arrive by bank transfer, card, or stablecoin. Withdrawals can return to bank accounts. Payment links handle send, request, and receive. Network fees are handled in the background. Users do not need to hold ETH for gas.
Idle balances can earn yield through Morpho from inside the app. 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. Amounts and balances are encrypted by default.
ERC-7984, the confidential fungible token standard drafted on ethereum.org, keeps an account-based model. Transfer amounts and balances become confidential pointers rather than public integers. Zama’s product pages say the interface mirrors ERC-20. Encrypted handles replace visible values. Access control covers authorized viewers.
That stack is what Raycash is productizing for payments. The company is not minting a competing dollar. It is wrapping an existing one.
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. Zama later said that first vault grew from zero to more than $40 million in shielded TVL within seven weeks. On September 15 it expanded to 16 confidential Morpho vaults across five curators and five asset classes, alongside confidential swaps.
Raycash’s Morpho earn feature sits on that same privacy-plus-yield path. It lives inside a payments app rather than a protocol dashboard. The beta claim is simple. You can send encrypted dollars. When you are not sending, you can earn without broadcasting position size on a public explorer.
What a Private Payments Beta Is Actually Telling You
Here is the recurring question this morning presses: when a stablecoin payment sits on a public chain, what does confidentiality at the amount layer change?
It does not change the dollar claim itself. USDC’s issuer relationship and reserve story stay upstream of the wrap. What changes is the visibility tax. Public balances and public payment amounts are a real inconvenience. That hits payroll, peer transfers, and anyone who does not want a wallet address to become a full spending diary. Encrypted amounts attack that inconvenience without inventing a new peg.
The failure mode to keep in view is trust migration, not 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 spend. A private beta is not proof that accountants, banks, or regulators will accept selective disclosure as enough. Those tests sit ahead of the invite list.
Unknowns remain. Public materials so far do not break out how many waitlist users are live in the beta, how much USDC is wrapped, or when Raycard ships. Broader stablecoin support is promised after USDC, without a dated schedule in the launch claim set.
The peg promise is still the same question it always was. This morning’s answer is about whether everyday dollar payments on Ethereum can hide the amounts without asking users to leave the dollar they already use.
