1 Backing up wallet

One of the important steps to secure your wallet by making a backup. A backup prevents losing RDDs in case of (accidental) data loss and corruption. With a backup, you can always restore your RDDs.

It is recommended to make regular backups.‌ Make new backups after creating a new receiving address and creating a new transaction.

There are two methods to backup, make sure to at least backup your wallet.dat (method 1).

1.1 Method 1: Backup wallet.dat

A wallet.dat backup contains all your Reddcoin addresses and private keys.

If your wallet is encrypted (has a password), the backup file will also be encrypted. Before you can make a transaction, you need to enter the password; so make sure you also have a backup of your password. If you lose or forget your password, you will not be able to access the RDDs in your wallet.

  • Open Reddcoin Core.

  • Use the menu to backup: Reddcoin Core → File (menu) → Backup Wallet…

    Give the backup file a name and save it by clicking on the ‘Save’ button.

  • Make sure to save the file in a safe and secure location.

1.2 Method 2: Backup your private keys

Every Reddcoin address has a private key. This private key is the prove that you are the owner of that specific Reddcoin address.

In case you lose your wallet.dat backup or your backup gets corrupted, you still can import your private keys later when needed. So, backing up your private keys is recommended.

Every Reddcoin address has its own private key. When making a backup of your private keys, make sure to backup the private keys of all your receiving addresses!

  • If your wallet is encrypted (has a password), unlock your wallet first.
    Reddcoin Core → Settings (menu) → Unlock Wallet…
    (make sure ‘For staking only’ is not checked)

  • Create a list of all your receiving addresses.

    • Open a text editor (Notepad, for example).

    • Get your receiving addresses: Reddcoin Core → File (menu) → Receiving addresses…

    • Copy every address that you see in your receiving addresses list to your text editor. To copy, you can select an address and press the 'Copy' button. Or right click an address and select 'Copy Address'.

    • After copying all your addresses, close the ‘Receiving addresses’ window.

If you have made any transactions (sent Reddcoin), you also might have hidden 'change addresses'.
To get the private keys of these change addresses, follow the steps below.

  • Open Reddcoin Core → Settings (menu) → Options → Wallet (tab).

  • Check ‘enable coin control features’ → OK.

  • Go to the Send window. At the top you will see an 'Inputs' button. Click on it.

  • A new window opens. In this window, make sure ‘list mode’ is selected.

  • Now, copy every receiving address with the label “(change)” to your notepad, by right clicking on the change address line.

  • Open Console: Reddcoin Core → Help (menu) → Debug window → Console.

  • In Console, enter the following command to ‘dump’ the private key of a Reddcoin address (that you copied from your text editor). Start with the first Reddcoin address in your list.
    dumpprivkey <your RDD address>

    After entering the command, Console will return the private key.

    Copy your private key from the Console to your text editor.

  • Repeat 'dumpprivkey' command for every Reddcoin address that you have.

  • Save the file with your private keys.
    Make sure to have backups, and store them somewhere safe.

You can write down your private key on a piece of paper, print it or copy and save it in a document. Make sure you save it somewhere only you can access it. If someone else gains access to your private keys, they can also access your coins!

2 Updating Reddcoin Core to a newer version

Newer versions of Reddcoin Core have bugfixes and new features. Updating to the most recent version of Reddcoin Core is recommended.

Use this guide to update an existing installation Reddcoin Core. If you are installing Reddcoin Core for the first time, you can follow this guide: Downloading and installing Reddcoin Core.

2.1 Check if most recent version of Reddcoin Core is installed

Currently, the most recent version is: Reddcoin Core v3.10.4.

To check the version of your Reddcoin Core, follow these steps:
