OneKey Classic 1S Pure Setup Guide

OneKey Classic 1S Pure Setup Guide

This walkthrough is the first time you take the OneKey Classic 1S Pure out of the box and create a wallet on it. The device has no battery, so it only turns on while the USB-C cable is plugged in. After it has power, the official OneKey app talks to it over Bluetooth. You still read the recovery words and the payment details on the device screen.

Buy: onekey.so/r/nordic/shop. OneKey referral code: Nordic.

Official pages if you want them open on a second screen: onekey.so/start and OneKey Classic 1S Pure help article.

Sit at a table where nobody can see the recovery words on the device.

What to put on the table

  • The sealed Classic 1S Pure box
  • The USB-C cable from the box
  • Your phone, with room to install the OneKey app
  • A pen
  • Power from a phone, a computer, or a charger

The Pure will not wake up without that cable.

The box

Look at the wrap and any seal on the carton. If it looks opened and taped shut again, contact the seller before you go further.

What is in the box

Open it and lay the parts out. You should see:

  • The Classic 1S Pure
  • A USB-C cable
  • Paper sheets for the recovery words (two in the box I opened)
  • Short setup papers and stickers

There is no wall charger. The four buttons on the device are power, up, down, and OK.

Install the OneKey app

The papers in the box have a QR code that opens OneKey's official download. You can also go to onekey.so and use the app link there.

This guide uses the phone app. The desktop app follows the same idea: connect a hardware wallet, then pick OneKey Classic.

Open the app. On the first screens you are looking for Connect hardware wallet, then OneKey Classic. The Pure uses that same Classic path.

Give it power, then pair the phone

The app may ask for Bluetooth next. The Pure still needs the cable first. Plug USB-C into the device and into power. Hold the power button until the screen comes on.

Set the language. English is fine if that is what you use.

When the phone lists the Classic device, select it. Accept the Bluetooth prompt. The device screen shows a short pairing code. Type that code in the app, then press OK on the device.

Check the device, then update it

Before you create the wallet, let the app confirm the device and install any firmware it offers.

In the app, open the genuine check (it may say Check my device). Press OK on the Pure when the device asks. If the app then offers a firmware update, start it and wait. Leave the cable in and keep the app open. When it finishes, tap Done in the app and press OK on the device.

Create the wallet on the device

The next screens are on the Pure itself. Press OK, choose Quick start, then Create new wallet.

The device asks how many recovery words you want: 12, 18, or 24. Those words are the backup. If this device is lost, the paper words are how you open the same wallet on a new OneKey. I use 24. Confirm your choice.

The words appear on the device screen, one group at a time. Write them on the paper from the box, in the same order. When the device asks you to pick the words back, do that so it knows the list is written down.

Then set a PIN. You will type this PIN later to unlock the device. Confirm it a second time.

The Pure should say setup is finished and send you back to the app. Restore is only if you already have recovery words from an old wallet and you want those on this device.

Optional referral in the app

When the new wallet appears in the app, there is a field for a referral code. It is not part of the security setup. If you want the in-app referral from the video, enter Nordic.

Add the coins you need

In the app, open Tokens and add the coins you plan to use. Search by name and look at the network next to each result so you add the one you meant.

After setup the app can send, receive, swap, and open extra tools. The Pure still has to approve on its own screen.

Send a small amount in first. When that arrives, you know the address and the network are right.

How a first send looks

Keep the USB-C cable in. Build the send in the OneKey app, then follow the prompt to confirm on the device. The Pure screen shows the address, the amount, and the fee. Scroll with the buttons if the address is long. Press OK on the device only when that screen matches what you intended.

A swap in the app works the same way at the end. You pick a quote on the phone, then you still approve on the Pure.

Extra settings you can leave for later

Later you can also turn on a new Bitcoin address for each receive, use bulk send, or switch the device to Bitcoin-only firmware in the OneKey app. None of that is required to finish today.

Checklist

  • The box looked sealed
  • The app came from onekey.so, the App Store, or Google Play
  • The USB-C cable is plugged in
  • Bluetooth is paired with the code from the device
  • The genuine check finished
  • Firmware was updated before I deposited coins
  • A new wallet was created on the device
  • The recovery words are on paper and were confirmed on the screen
  • A PIN is set
  • A small test amount arrived
  • A small test send showed the right address on the Pure before I pressed OK
  • There is no photo of the recovery words on this phone

From here the habit is simple. Plug in the cable, build the payment in the app, read it on the Pure, press OK.
