How to use the Tangem Backup xApp

Congratulations! If you are reading this you have decided to use the Tangem Backup xApp to create a backup for you XRP Ledger account.

This is a very wise decision!

Please make sure you review this contents of this article upon completion of these steps.

• Tangem cards - Best Practices

Before you get started

Before you can use the Tangem Backup xApp, you need two things:

1. An account on the XRP Ledger that is currently imported into XUMM and has been activated with at least 10 XRP. It can be another card account or a non-card account. Either one will work.
2. A XUMM Tangem card that that has been imported into XUMM.

Note: Most people will choose to use two cards to do this procedure.

To confirm, you must ensure that both cards have been imported into XUMM, but only one of them needs to have been activated with 10 XRP. The 2nd card does NOT need to be activated. If you do not know how to do this, please see this video:

Note

Throughout this article we refer to "Card 1" and "Card 2" to differentiate between them.

• "Card 1" is the card the you will activate with 10 XRP. This account will hold your XRP and your other assets. You can label it anything you like XUMM. (ie. "Savings" or "Spending Account", etc.) but this account is your primary account.
• "Card 2" will be your daily sign card. It will be used to sign transactions on "Card 1" Again, you can label it anything you like in XUMM. ("Signing card" or "Savings signing card" or whatever you like) 

Getting started

Start by launching XUMM and pressing the "x√" button at the button of the screen.

Next press Tangem Backup.

(If it is not listed there, press the "View more xApps" button and the Tangem Backup xApp should be listed on the follow screen.)

Alternatively, you can scan this QR code using XUMM:

Welcome to the Tangem Backup xApp

You should be at this screen.

Press the "I'm ready, continue" button and you should see this screen:

This is where you get to choose your primary card. This is the one that has been activated with at least 10 XRP. When you are done, this is the card that will be stored away in a safe place. We refer to it here as Card 1. Press Select account.

Slide to accept and close the confirmation screen. You will see this screen:

This is where you choose your backup card. This is the one that does not need to be activated. When you are done, this is the card that you will use to sign transactions on Card 1. We refer to it here as Card 2. Press Select back up card.

Slide to accept and close the confirmation screen. You will see this screen:

Press the "Next Step (finish) button". You will see this screen:

Slide to accept then sign the transaction with Card 1.

Congratulations you did it!

So what do I do now? How do I use the cards?

Now that you have completed the process, you have the option to sign transactions on Card 1's account with either Card 1 or Card 2.

After you create the transaction, then "Slide to accept" you should see this screen:

To confirm, you can now use both Card 1 and Card 2 to sign transactions on Card 1's account. 

If you lose or damage either card, you can use the other card to move your funds off of Card 1's account to another XRPL account. While this will work, we strongly suggest you review this article for more information on how to use your cards

But I have more cards and I want to set them up as backups as well!

Unfortunately you can not do this on the XRP Ledger. You can only have one backup per account. You can create another primary account, then create another backup card for that account, but you can not have a second or third backup card for one account.

Notes

We understand that you might have additional questions regarding this procedure so you are welcome to contact us any time via the XUMM Support xApp in XUMM or you can simply scan this QR code with XUMM and be directed there automatically.
