Parallax Wallet, the desktop app, works with Ledger and Trezor hardware wallets. The device keeps the keys: the app only knows the accounts’ addresses, and every transaction or message from them is checked and confirmed on the device’s own screen before it’s signed. Even a compromised computer can’t send from them without you.

​
What you need

  • A Ledger (Nano S Plus, Nano X, Stax, Flex or Nano Gen5) with the Ethereum app installed from Ledger Live, or a Trezor (Model One, Model T, Safe 3 or Safe 5), set up and with its firmware up to date.
  • Parallax Wallet with its node, connected to the computer by USB.
  • Close Ledger Live or Trezor Suite while you use the device with Parallax Wallet: only one app can talk to it at a time.
There’s no Parallax app to install on the device. Parallax accounts use the same paths as Ethereum’s (coin type 60) and are signed by the device’s Ethereum app for Parallax’s own chain ID, 2110, so a signature for one network can never be replayed on the other. The device may not know Parallax by name: it can show the amount as ETH and the network as chain 2110. It’s LAX on Parallax, as the app shows.

​
On Linux: USB access

Linux gives a USB device to the user at the computer only once a rule allows it, which Ledger’s and Trezor’s own apps install and an AppImage can’t. If the app says it can’t open your device, choose Set up USB access where it says so: it installs the rules for Ledger and Trezor devices, asking for an administrator’s password. Then unplug the device and plug it in again. macOS and Windows need nothing.

​
Add your accounts

1

Connect the device

Plug in your Ledger or Trezor and unlock it. On a Ledger, open the Ethereum app.
2

Start the import

Open Settings → Accounts → Import accounts → Connect a hardware wallet. The app shows how the device stands until it’s ready:
  • Ledger: unlock it, then open the Ethereum app, as it asks.
  • Trezor Model T, Safe 3, Safe 5: enter the PIN, and your passphrase if you use one, on the device’s screen.
  • Trezor Model One: the device shows its digits shuffled on a grid; press the same places on the blank grid in the app. If it asks for a passphrase, type it in the app (leave it empty for the wallet without one).
Once it’s ready, choose Continue.

Pick the accounts

The app reads the device’s accounts, with what each holds on Parallax, and selects those that have been used. Choose the ones to add, then Add accounts. More load on demand, and you can look along other paths (see below).
The accounts are added to the wallet, each named Account N as other accounts are, and you can rename them. Nothing secret is kept: the app stores each account’s address and where it is on the device.

​
Derivation paths

Wallets put a device’s accounts along different paths. The app can look along the three in use: Account 0 is the same address on Ledger Live’s path and the standard one, so it’s offered once. If you’ve used your device’s accounts on Ethereum with Ledger Live or MetaMask, the same addresses are yours on Parallax.

​
Hardware wallets in Settings

Settings → Accounts gathers your accounts under Hardware wallets, one group per wallet your devices hold:
  • Named as you like. Each starts as Hardware Wallet 1, Hardware Wallet 2 and so on, with a Ledger or Trezor badge. Point at its heading and choose the pencil to rename it.
  • Told apart by the wallet, not the device. A wallet is its recovery phrase: two devices restored from the same phrase hold the same wallet, and either signs for its accounts. On a Trezor, each passphrase opens a wallet of its own, so each has its own group.
  • Find accounts adds more of a wallet’s accounts. It reads them from a connected device that holds that wallet, and says so if the one plugged in holds another.
  • By path. Where a wallet’s accounts are on more than one path, they’re listed under Ledger Live, Standard and Legacy, numbered along each.
The account switcher lists them under its Hardware tab.
Accounts added with an earlier version of the app are first listed under the kind of device alone (“Ledger”). The next time you connect and unlock that device, the app sorts them into their wallet’s group.

​
Send and sign

Sending from a hardware wallet account is the same as from any other, with no password: the device confirms instead.
  1. Fill in Send and review it, as usual. While the device isn’t ready, the review says what it needs (connect it, unlock it, open the Ethereum app).
  2. Choose Sign on Ledger (or Trezor). The device shows the transaction.
  3. Check it on the device: the recipient’s address, the amount and the fee must match the review. Then approve it there. To cancel, reject it on the device.
The same goes for speeding up or cancelling a waiting transaction, and for signing a message under Messages: the device shows the message to check before you approve it.

​
Check your address on the device

On Receive, a hardware wallet account has Verify on Ledger (or Trezor). The device shows the account’s address: compare it with the one in the app before you share it. What a computer shows can be tampered with; what the device shows can’t.

​
AI assistants

An AI assistant can ask to send from a hardware wallet account. You review the request in the app, then confirm it on the device: no password is involved. If the device isn’t ready, the request waits for you to connect it and approve it again.

​
Remove an account

Removing a hardware wallet account from the app needs no password: its key stays on the device, and you can add it again any time with Find accounts. A wallet’s group goes with its last account.

​
Keep it safe

  • Your device’s recovery phrase is the backup. The app keeps no copy of any hardware wallet key. Lose the device and you restore its accounts from its recovery phrase, on a new device or any wallet.
  • Confirm only what you meant. Check every transaction on the device’s screen, not only on the computer’s.
  • Keep the firmware and the Ethereum app up to date, from Ledger Live or Trezor Suite.
