Physical confirmation
for every transaction

Three steps to
total self-custody.

01
Generate your seed

The device arrives completely blank. During first setup, you generate your 24-word seed phrase directly on the device itself — it never leaves the chip, and we never see it.

02
Connect & manage

Install the companion app on your phone or desktop and connect your VaultKey via USB-C or Bluetooth. View balances, initiate transfers, and manage multiple wallets — all from one place.

03
Confirm physically

Every transaction must be reviewed and physically confirmed using the buttons on your device. The transaction details appear on-screen — nothing moves without your explicit approval.

Built for true
ownership.

Every component of VaultKey was designed to give you full, uncompromised control over your digital assets.

Offline Key Storage

Private keys are generated and stored exclusively on the device's Secure Element chip. They never touch the internet — not during setup, not ever.

Physical Transaction Confirmation

Every outgoing transaction must be confirmed by pressing the physical buttons on your device. No remote approval, no software bypass.

Secure Element Chip

The certified Secure Element chip is hardened against physical and side-channel attacks — the same technology used in bank cards and passports.

Bluetooth & USB-C

Manage your portfolio from your mobile phone via Bluetooth or connect to a desktop via USB-C. Compact USB-stick size — fits on your keychain.

5500+ Supported Assets

Bitcoin, Ethereum, Solana, BNB, XRP, Cardano, Avalanche, Polygon, and thousands more coins, tokens, and NFTs — all in one device.

Recovery Phrase Backup

A standard 24-word BIP39 seed phrase provides full wallet recovery if your device is lost or damaged. Write it down and store it safely offline.

Your seed.
Never ours.

We designed VaultKey around one principle: only you should ever have access to your funds. From factory to your hands, complete control stays with you.

Common questions.

Your 24-word recovery phrase is all you need to restore your entire wallet on a new VaultKey or any other compatible BIP39 hardware wallet. Store your seed phrase offline in a safe place — anyone with access to it can access your funds.
No. Every VaultKey ships completely blank and factory-fresh. Your seed phrase is generated on the device during your first setup. We never see it, store it, or have any access to it — it is created entirely by the device itself.
No. Your private keys and seed phrase are stored completely offline inside the Secure Element chip. Internet is only needed when you use the companion app to broadcast a signed transaction to the blockchain — your keys never go online.
Every transaction must be physically confirmed by pressing the buttons on your device. The recipient address and amount appear on the device screen for you to verify before signing. Without your physical confirmation, no transaction can be sent.
A seed phrase (or recovery phrase) is a set of 24 words that can regenerate your entire wallet. Write it down on paper and store it in a secure, offline location — such as a safe. Never store it digitally, never photograph it, and never share it with anyone, including us.
Yes. VaultKey supports NFTs on Ethereum, Solana, Polygon, and other compatible networks. You can view, store, and transfer NFTs through the companion app while keeping their associated keys fully offline.

Not your keys,
not your coins.

Take true ownership of your digital assets. Your keys, generated by you, stored offline by you — forever.
