PRIVACY IS PERSONAL

Choose what you share.

Not every payment needs the same privacy.
Pick the right level, every time.

01

Standard

Out in the open.

For trading, swapping, and everything that needs to work with other apps.

  • Public amounts & addresses
  • Works with DEXs and DeFi
  • Familiar, everyday transfers
~$0.001 / payment
02

Private

Keep the numbers to yourself.

For payroll, invoices, and payments where the amount is your business.

  • Encrypted amounts & balances
  • Sender & recipient stay visible
  • Privacy without the extra cost
~$0.001 / payment
03MOST PRIVATE

Shielded

A little more like cash.

For payments that keep your amount and the connection between wallets private.

  • Hidden amounts & balances
  • Unlinked sender & recipient
  • Protected by zero-knowledge proofs
~$0.35 / payment

Illustrative network fees. Actual costs vary. Private and Shielded balances cannot be used directly on a DEX.

LESS FRICTION. MORE FREEDOM.

Your dollar, upgraded.

Familiar money. A more private way to move it.

01

Bring your USDC.

Connect your Solana wallet and wrap USDC into zkUSD, one for one.

02

Make it yours.

Choose Standard, Private, or Shielded for each payment. You set the boundaries.

03

Move on your terms.

Send zkUSD, or redeem back to USDC. The choice stays with you.

PRIVATE, NOT OPAQUE

Trust starts with
transparency.

Your payments deserve privacy.
The protocol behind them deserves scrutiny.

1:1
Backed by USDC

One USDC held in reserve for every zkUSD. Public supply. On-chain backing.

Your tokens stay yours.

No freeze authority, no permanent delegate, and no admin transfer path for zkUSD. Minting is restricted to the program and backed by locked USDC.

Public backing. Private payments.

Supply and reserve accounts are public, so anyone can check the backing at any time, while the payments themselves stay private.

Math, not promises.

Every shielded payment carries a zero-knowledge proof that the program checks on-chain before a single token moves. Each note can be spent exactly once, and hidden amounts are tied to the transfer that carries them by a proof across two curves.

A LITTLE PRIVACY GOES A LONG WAY.

Make money personal again.

Your next payment doesn’t have to be everyone’s business.
