Your phone or browser is online. It sends a request to your computer, which is offline. You approve, and the signed result comes back to be broadcast.

Illustration. No transaction is created.

  1. Start on your phone or browser.

    Begin a payment or an approval. 0xStealth asks your computer to sign it.

  2. Read it in plain words.

    The request reaches your computer by QR code, file, an encrypted link or Bluetooth. Every request is spelled out in plain words before you approve it.

    • File
    • Local linkbrowser
    • Your networkphones, free
    • Bluetoothphones, Pro

  3. Approve on your computer.

    You give the go-ahead. The signed result goes back the same way it came in.

  4. Your phone or browser broadcasts.

    It sends the signed transaction to the network. Your computer stays offline.

A careful first hello.

When you pair your phone or browser, both sides show the same 6-digit code. Check that they match. Unknown devices are refused.

The link between them is encrypted.

Nothing here connects to the internet.

The internet stays with your phone or browser. Your computer keeps your keys and waits for your approval.

  • Offline by design

  • Your phrase stays home

    Your recovery phrase stays on your computer unless you choose to import it from your phone or browser.

Pair a phone or browser. It shows your addresses and asks your computer to sign.

Manage from your phone Free

Your wallets, from your phone or browser.

Make a wallet, add and rename accounts, and pick which can be Travel Keys. A new wallet’s recovery phrase is made on your computer and stays there.

Importing a recovery phrase asks you to confirm it on your computer. Deleting happens only on your computer.

Travel Keys Use with Pro

Sign without your computer.

Pick accounts to sign with on your phone or browser, until a date you choose. You approve each one on your computer.

How Travel Keys work

Key backup Desktop app

One file for your keys, kept where you put it.

The desktop app saves your recovery phrases and imported keys to one file, locked with its own password. It says plainly that the file holds your keys.

It stays where you save it. It never goes to the cloud, and the phone and browser apps refuse it.

Networks, signed and ready

Built-in networks come from our signed registry. You can add your own on your phone or browser. Curated token lists come with Pro.

  • Ethereum
  • PulseChain
  • Arbitrum One
  • OP Mainnet
  • Base
  • Polygon
  • BNB Smart Chain

Free and Pro

Offline signing is for everyone. Free lets you add as many addresses as you like, link your phone over your network or your browser on the same computer, move requests by QR code or file, broadcast, back up your accounts by hand, and manage your wallets from your phone or browser.

0xStealth Pro adds encrypted sync across your devices, automatic backup, Bluetooth on your phone, Travel Keys on your phone or browser, the passphrase keypad and curated token lists. It’s billed monthly or yearly, and one subscription works on every device that shares your sync key.

Carry what you need. Leave the phrase at home.

Travel Keys let your phone or browser sign for accounts you pick, without your computer. Encrypted sync keeps your devices in step. Neither one moves your recovery phrase.

Travel Keys Use with Pro

Take the accounts you need. Leave the phrase.

Sign without your computer, until a date you pick.

You approve each key on your computer. It’s locked with your travel password, and your history marks what it signed.

  • Pick an end date, up to the limit set on your computer. It’s removed then, or sooner if you remove it.
  • On a phone, Face ID or a fingerprint unlocks it for each signature. The browser asks for your travel password, then stays unlocked for a while.
  • A travel key can sign any amount.
  • It moves only over an encrypted link or Bluetooth. QR and file transfer refuse it.
  • With Pro sync you can share them with your other devices, locked with your travel password.

Encrypted sync Pro

Your setup, together. Your signing keys, apart.

Everything is encrypted. Our server can’t read it.

Sync your addresses, custom networks and tokens, settings and Account List. Sync and backup never hold your keys or recovery phrases, except Travel Keys you choose to share, locked with your travel password.

  • Join with a one-time 12-word key or a QR code. It isn’t your recovery phrase.
  • Restoring the Account List shows a human canary and “your coded book is backed up”.
  • Your keys are backed up only in the desktop app’s key backup file.

Updates without the internet

Your phone or browser can pass a desktop update over the link. The desktop app then asks you to “restart to update”. You can also update from a file.
