Your wallet.
One tap away.
A brushed steel card that opens your crypto wallet in the browser. Nothing installed on your phone. No account, no email.
Cards from $149. Ships worldwide.
Tap. Unlock. Use.
Three seconds from pocket to balance. The card is the entry point — without it, there is nothing to open.
Hold the card to your phone
The back of the card meets the back of the phone. Your browser opens on its own.
Enter your PIN
The card alone is not enough. Your PIN is the second half, and only you have it.
Send, receive, swap
Nine networks, about thirty assets. Close the tab and the session is gone.
Everything you need.
Nothing you don’t.
Balances, sending, receiving and swaps. No feeds, no banners, no token of the week. The screen closes when the tab does.
No app.
Your wallet does not live on your phone. There is no icon on the home screen, no entry in the app list, nothing to find in a backup.
- On your phoneNothing. The wallet opens in a browser tab and closes with it.
- On the cardOne number, printed as an NFC tag. It looks like a link, not a wallet.
- In your pocket316L steel with a brushed face. It reads as a card, because that is what it is.
Lose the phone.
Keep the wallet.
A phone is the part of this you are most likely to lose. With a wallet app, that is the moment everything goes wrong. Here it is the moment nothing happens.
- Nothing to findNo icon on the home screen, no entry in the app list, no purchase sitting in your App Store or Play history. There is no wallet app on the phone, so there is no wallet app to notice.
- Nothing to extractYour keys are built when you tap the card and gone when the tab closes. A full forensic copy of the device holds no key, no seed phrase and no balance, because none of it was ever written there.
- Nothing in the backupiCloud and Google backups copy apps and the data inside them. There is no app and no data, so nothing about your wallet travels into the cloud with the rest of your phone.
- Nothing to replaceBuy any phone, tap the same card, enter the same PIN. You are back in a few seconds. The wallet lives on the card and in your head, never on the device.
What we do not claim: a browser still records that a website was opened, and we will not pretend otherwise. What it never holds is a key, a seed phrase or a balance. Clearing your browsing data removes the trace; nothing about your funds depends on it.
Will it work with your phone?
Almost every phone made since 2018 opens the card with no setup at all. Check yours before you order. If we get this wrong for your model, we refund the card in full within 30 days.
Where the keys are.
Hardware wallets like to talk about secure elements. DusX works differently, and it is worth being precise about it rather than borrowing someone else’s sentence.
- Derived, not storedYour private keys are built inside your browser each session, from the number on the card combined with your PIN. They are never written to the card, and never written to our server.
- Two factorsSomeone who steals the card gets a number. Someone who learns your PIN gets a number. Both together open the wallet.
- No account, no nameNo sign-up, no email, no phone number. The server rate-limits PIN attempts and nothing else. We cannot identify you, so we cannot hand you over.
- Recovery is yoursYou write down a seed phrase when you set up the card. It restores your funds in DusX or in any other standard wallet. We hold no copy and cannot make one, which also means we cannot freeze or move anything.
- Audited before shippingAn independent cryptography and code audit is being completed now. The report will be published in full here before the first card ships.
Choose your finish.
Same steel, same thickness, same chip. The difference is the face, and how much attention it asks for.
Steel
Brushed natural steel with an etched wordmark. The quietest of the three.
Graphite
Dark PVD over the same brushed grain. Holds fingerprints less than black.
Obsidian
Deep black PVD with a polished edge and a single moissanite set into the corner.
Straight answers.
Including the ones that are inconvenient for us.
What happens if I lose the card?
Your wallet lives on the blockchain, not on the card, so the funds are not lost. You restore it from the seed phrase you write down during setup — in DusX or in any other wallet that accepts a standard seed phrase. Without that seed phrase, a lost card means lost funds. We have no copy of it and no way to make one.
Can someone who finds my card drain it?
Not with the card alone. Tapping it opens a screen asking for a PIN, and PIN attempts are rate-limited on our side. Choose a PIN you do not use anywhere else, and treat the card the way you would treat a key.
Do I need to trust your server?
Partly, and you should know exactly where. The server delivers the page, checks that a PIN attempt is allowed, and proxies price and swap requests. It never receives your seed phrase or your private keys. If our server disappears tomorrow, your seed phrase still opens your funds in any standard wallet.
Is it really untraceable?
No, and anyone promising that is selling something. A browser leaves traces we do not control: DNS records, network metadata, your operating system. What DusX removes is the obvious one — an app on your phone announcing that you hold crypto. That is a real difference, and it is not the same as invisibility.
What can I actually do with it?
Hold, send and receive across nine networks, including Bitcoin, Ethereum, BSC, TRON, Polygon, Arbitrum, Base, Optimism and Avalanche, covering around thirty assets. Swaps run through an external exchange provider inside the wallet screen.
