Pre-order hardware wallet rebate will be sent directly to hardware wallet ETH account upon activation of device.

The device PIN is a 4-8 digits numerical string that could be set during the device initialization process. You will see a check mark after entering the 4th digit. Selecting the check mark means that your PIN is set as 4 digits length. Use up and down to select number if you intend to make a PIN longer than 4 digits.

An 8 digits PIN is recommended.

For security purposes, JuBiter wallet is not able to restore your PIN when your PIN is lost. However, you can reset the device and restore your wallet again with your recovery phrases.

PIN matrix shows up when you try to initiate a transaction. Unlike the regular PIN input, PIN matrix needs both your phone/PC and your hardware wallet for entering the PIN. Hardware wallet will generate a 3-3 PIN pad with a random layout of numbers. Users need to enter the PIN on phone/PC according to the position of each number displayed on the wallet screen.

This method protects you from keyloggers – your phone/computer never knows what you have entered as you just entered some random “positions”. Only the hardware wallet itself can “translates” the clicked positions into the actual PIN numbers. It also makes it impossible for other people to obtain your PIN.

If you just cannot find the recovery card, most likely you are still in possession of your crypto assets as long as your hardware wallet is available. Your crypto assets could be in danger only if the recovery card is stolen by someone. If such instances occurred, you should create a new wallet and transfer all your assets to the new wallet immediately.

The recovery phrases usually contains a sequence of 12/18/24 English words,  uniquely and securely generated from your hardware wallet when you first set up. It is very important to keep these backup English words secret and in a safe location.

In case your device gets lost, you will need these recovery phrases for getting your wallet back. These recovery phrases can also be used for restoring your wallet in any other wallet or application which supports the same standard (BIP39).

Incorrect account balance can be caused be several reasons:

  • The synchronization was interrupted before it is complete. You can tap and enter the detail page of a coin/token and refresh the balance again.
  • See whether you have chosen the right fiat currency display.
  • If the problem is happened on Bitcoin, especially in the case that the default Bitcoin account cannot show your balance at all, you then may need to check whether your money is in a Bitcoin segwit address. To do so, tap “add currency” – “BTC”. Then you will see a pop up for entering PIN and coin name. Tap “advanced settings” and mark the “Segwit” option. Add the BTC and you will see your balance here.
