Live and read-only. Link Ready to move money.
Why Ready specifically
Nothing is signed until you approve it in Ready, and submitting stays disabled until a wallet is linked. Ready generates and holds your viewing key on your device and produces the proofs behind every private action. That is why it is required for these, even though other Starknet wallets can hold your public funds.
Withheld, not empty. The figure is encrypted on chain and only your viewing key decrypts it, so link Ready above and it reads from your own notes.
Settle a payment
Pay a merchant or acquirer directly from your shielded balance.
How this works
The address you pay and the amount are visible onchain, the same as any card settlement. What stays hidden is which of your notes paid it and what you have left.
Sealed · settled record
sepoliaA swipe has already settled from a shielded balance
One transaction sells shielded STRK, pays the merchant in USDC and records the authorization. The receipts below are those swipes, read back against Sepolia. Every card contract in this product is deployed on Sepolia only, so none of this has run on mainnet and none of it moved real money.
What has settled: card authorizations against the pool
- A swipe settles privatelySUCCEEDED

Shadow spend through a per-merchant identity, so two visits to one merchant do not chain.

These settled through a hosted account that holds its own server side viewing key, so Sealed's operator can see them. That is why this surface is marked partial rather than live, and the form below submits from your own wallet instead, which the operator cannot read.
