Spend Without a Trace Anywhere On Earth

A non-custodial payment card that settles on-chain and reveals nothing about you. Shielded balances, one-time addresses, and zero identity fields — checkout looks ordinary, the ledger stays quiet.

Meet CIPHR.

Discover it

CIPHR is a dollar card that spends like any other and settles like none of them — the balance is yours, the route is shielded, and the ledger keeps its mouth shut.

Balances that stay yours

Funds sit in a shielded pool you alone can spend from. No issuer float, no frozen accounts, no support ticket standing between you and your own money.

Always liquid,
always dollar

Hold a dollar-denominated balance with instant access — no lockups, no notice periods, no waiting for a settlement window.

Nothing to
manage

Proofs, nullifiers and rotation happen on-device in the background. You tap the card; the cryptography does the rest.

// Protocol

Three moves,
nothing leaked

  1. 01 — Fund

    Deposit into the pool

    Send any supported asset from your own wallet into the shielded pool. The deposit is public; everything after it is not.

  2. 02 — Shield

    Mint a private note

    Your balance becomes a commitment in the Merkle tree. A zero-knowledge proof — not an account name — authorises every later spend.

  3. 03 — Spend

    Pay from a fresh address

    Each authorisation burns a nullifier and settles from a one-time address, so two payments can never be linked back to one card.

// Capabilities

Privacy,
engineered

One-time addresses No KYC Unlinkable Off-graph

Stealth Spending

Every authorisation derives a fresh receiving address from your viewing key. Merchants see a payment; chain analysts see noise.

Sub-second proofs Gas abstracted Batch settle Any asset

Instant Settlement

Proofs are generated on-device and relayed in a single batch, so a shielded payment clears in the time an ordinary card takes to beep.

Self-custody Open source Audited circuits Revocable

Your Keys Only

No issuer holds your balance and no server holds your keys. Freeze, rotate or burn a card yourself — the contract takes the instruction, not a support desk.

// CIPHR in practice

Use modes

The same shielded rail carries a coffee, a payroll run and a cross-border settlement. Four ways teams put it to work today.

01 — Commerce

Checkout that keeps its receipts to itself

Take payment in a dollar-denominated asset without asking a customer for identity they would rather not hand over. You see the settlement; the chain does not see the shopper.

02 — Treasury

Operating cash that isn’t a public spreadsheet

Hold reserves without publishing your runway, your counterparties or your payroll dates to anyone with a block explorer. Withdraw the full balance on any day of the week.

03 — Fintech apps

A private balance inside your own product

Drop shielded card rails into an app with one integration and keep your brand on the front of it. Your users get privacy by default; you never become the custodian of their keys.

04 — Payments

Cross-border in minutes, not correspondents

Settle between countries without a chain of intermediaries reading every leg of the transfer. One proof, one hop, and the amount stays between the two parties to it.

The network asset for the shielded pool: it pays relayer fees, backs the anonymity set, and carries governance over circuit upgrades. Launch is on Pons on Robinhood Chain. Dexs often have nothing until the bonding curve graduates — this panel reads the Pons factory and the chain, not DexScreener. Verify the CA here before you buy anything.
