Private Vaults in a self-custody wallet: privacy on device, not invisible crypto

Looking for a hidden wallet or private crypto vault? GreyWallet Private Vaults isolate wallets behind a private pattern on your phone — device-level privacy, not undetectable on-chain activity. Here’s what that means in practice.

People search for “hidden wallet,” “secret crypto wallet,” or “private vault app” when they want balances that do not sit in the everyday wallet screen. GreyWallet’s answer is Private Vaults: an optional, isolated space on your device, unlocked with a private pattern you choose.

Private Vaults hide wallets from Home, Assets, and Activity until the pattern is entered. They do not make the app invisible, and they cannot hide transactions after they are broadcast on-chain.
GreyWallet product principle

What Private Vaults are

Private Vaults are part of GreyWallet’s self-custody design on iOS and Android. You create or import wallets as usual. Vaults let you keep some of those wallets out of everyday views — useful when you share a device briefly, or when you want a clear separation between daily spending balances and longer-term holdings.

Optional isolation — not required to use GreyWallet.
Unlocked with a private pattern on the device.
While locked, vault wallets do not appear in Home, Assets, or Activity.
Once unlocked, you send, receive, and manage those wallets like any other GreyWallet account.

What Private Vaults are not

Marketing often oversells “undetectable” wallets. That language is misleading. GreyWallet documents the limits clearly so you can decide whether the feature matches your threat model.

The GreyWallet app icon and presence on the device are not hidden.
Anyone with physical access and enough time may still know a wallet app is installed.
On-chain transfers are public by design of the network you use — vaults do not rewrite blockchain history.
Grey Holdings support cannot reconstruct a forgotten private pattern. There is no backdoor reset.

If someone promises an undetectable wallet that support can recover for you, treat that as a red flag — those two claims usually cannot both be true.

How the private pattern works

The pattern unlocks the vault space on this device. The raw pattern is not stored in a form that support can recover. A different pattern on the same device can create a separate vault space. Optional space names are visible only while a vault is open.

01Set up GreyWallet with create or import as you normally would.
02Configure Private Vaults and choose a private pattern you can remember offline.
03Move or create wallets into the vault according to your workflow.
04Lock the vault when you return to everyday use — those wallets leave Home, Assets, and Activity until unlocked again.

Security habits that actually matter

Vaults complement — they do not replace — basic self-custody hygiene. Your recovery phrase still protects the underlying HD wallets. Losing the phrase loses access to funds whether or not a vault was used.

Write the vault pattern offline, separate from cloud screenshots.
Never send the pattern to support@greywallet.app or anyone claiming to “verify” your wallet.
Do not reuse the pattern as a password elsewhere.
If you forget the pattern, treat vault contents as inaccessible on that device path — plan backups before you rely on vaults for critical funds.

Who Private Vaults are for

Private Vaults fit users who want device-level separation: shared phones, travel, or simply cleaner everyday screens. They are not a substitute for operational security against sophisticated attackers, and they are not anonymity software.
