A money account the public ledger can't read.

Hold, spend and send on Starknet. Everyone can see that you have an account. No one can see what is in it.

Live on Starknet mainnet for holding, shielding, private send and unshield, through the canonical STRK20 pool. The card, vault and bridge loops run on Sepolia, where this project's own contracts are deployed. Not a licensed bank. Not a mixer.

The public chain shows these as six transfers in and out of a pool address; whose account they are and what is left in it stay under the viewing key.

Every row links to its receipt on Voyager. Amounts come from src/lib/evidence.ts and strk20.json.

What's hidden, what isn't

A privacy pool on a public blockchain is not invisible. It is selectively decryptable. Here is exactly what that means, fact by fact, not a marketing promise.

  • HiddenWhich other notes were spent alongside yoursUnlinkable. Protected by the pool’s anonymity set.
  • Key gatedSender and receiver of a private transferDecryptable by whoever holds either side’s viewing key.
  • Key gatedPrivate transfer and spend amountsDecryptable by a viewing-key holder.
  • Key gatedYour current shielded balance and history in the poolDecryptable by a viewing-key holder.

Who sees what, party by partyThe custodial exceptionWhat we refuse to claim

Who holds the key that unlocks the revealed column?

Your personal wallet generates and holds your viewing key on your own device the first time you shield with it. Sealed's app code never receives or stores it. The one exception is the hosted card-settlement account used to process swipes: it has its own separate, server-held viewing key so it can operate that one account. It cannot decrypt your personal wallet's notes.

Why does it have to be Ready?

Private actions need a wallet that implements the Starknet privacy wallet API, the part that generates your viewing key on-device and produces the proofs behind every private transfer. Ready is the wallet that does this today. Other Starknet wallets can still hold your public funds; they just can't do the private actions yet.

Not a demo recording. Four receipts you can open.

Four of the transactions on the record: one on mainnet against the live STRK20 pool, three on Sepolia through this project's own contracts. Each is confirmed on chain, so click through to Voyager and read it yourself.
