How to backup your wallet

We often see users not take the necessary precautions to protect their investment. This guide has been designed to help you create the necessary backups of your investment, and provide the necessary restore procedures.

Help needed ?

If you need any assistance making a backup or restoring your backup, please visit us on Discord here. We have moderators on 24/7 that will assist you.

Keep in mind, the screenshots might differ a little bit between operating systems.

There are 2 ways to backup your wallet, and they complement each other.

  • Backup of the wallet.dat
  • Backup of your private key(s) offline/cold storage

We advise you to follow both backup procedures, to make sure you never lose access to your coins.

Method 1: wallet.dat backup

Open your wallet and select file -> backup wallet

Save your backup wallet.dat to a location on your computer and then move it to (for example) a USB stick.

If your wallet is not encrypted, you need to be very careful with your wallet.dat (offline storage is advised).

Method 2: Export the private key(s)

  • Open the QT wallet and unlock
  • Make sure you do a full unlock
  • Now open tools -> debug console
  • Type listaddressgroupings and press <enter>, this will list all wallet addresses
  • Now extract the private key of each address that you want to migrate using the following command. (If the wallet is not in sync you will not see any balance but you can export all the keys instead)

Safety !

The private key gives access to your coins without any password or other failsafe. You NEED to keep this 100% secure. For example, put them on a paper/usbstick and put them in a safe (possibly together with a guide for next of kin incase of an emergency).

How to restore your wallet

Before we restore the wallet.dat or private key, install/upgrade the LUX QT and have it fully sync with a fresh wallet.dat

Method 1: wallet.dat restore

Please close your QT wallet.

Open explorer and enter %appdata%\lux and press enter

Replace the wallet.dat with your backup. The name of the backup has to be exactly “wallet.dat”.

Start the wallet.

Method 2: Import private key(s)

If you made a fresh wallet.dat to import your private key, we advise you to encrypt your wallet.dat first.

  • Open the QT wallet and unlock
  • Make sure you do a full unlock
  • Now open tools -> debug console
  • Import the private key
  • The wallet will now rescan all the blockchain files for transactions, this may take a while. Repeat this process for all your private keys. They will now show up under file -> receiving address and the transactions and balance should be updated after a restart of the wallet.

Safety!

The private key gives access to your coins without any password or other failsafe. You NEED to keep this 100% secure. For example, put them on a paper/usbstick and put them in a safe (possibly together with a guide for next of kin incase of an emergency).

How to update/reset your wallet

For a cryptocurrency with an ambitious roadmap like LUX mandatory wallet/blockchain upgrades are a common occurrence, they are required to implement new functionality to the network and therefore should always be kept up-to-date. This guide describes how to upgrade/reset your wallet.

When do you reset your wallet ?

  • Wallet does not sync anymore (no block source available)
  • Wallet does not receive or send a transaction from/to an exchange or pool
  • When you upgrade your wallet
  • When a mod on discord asks you :)

Backup

Before you continue, please verify you have proper backups in place, you can check the backup guide for help here

Close the QT wallet

Please close your QT wallet

Open the LUX data folder

Open explorer and browse to "%appdata%\lux"

** This is the default installation folder

Clean up the data folder

Select all files except the wallet.dat and backups folder (the backup folder is not present in v3 wallet directories).

Delete files

Now delete the files, result:

Download blockchain files

Download the latest blockchain file here and unpack all files and directories into the lux folder. The end result should look like this:

Download latest wallet

Open a browser and download the latest lux-qt-wins.zip on our Github page and unzip the lux-qt.exe somewhere convenient.

Start the wallet

Start the wallet, it will now start synching from a recent state of the blockchain.

As we have placed a recent copy of the blockchain in the installation directory, the sync will be fast (few minutes).

Verify your wallet is synced properly

Mouse over the checkmark in the bottom right corner of your wallet.

Compare the block number to the block explorer on our explorer
