Setting up your Casa vault for ordinals and inscriptions

This article details how to set up Casa's 3-key vault prior to securing ordinals and inscriptions. The 3-key vault is available to all Casa Gold members.

While you can use Casa to store your ordinals and inscriptions, it's also a key manager that can store your bitcoin (BTC) long term, and, coming soon, your ethereum (ETH).

Important note: While storing and sending ordinals / inscriptions is possible within the Casa app, the Casa app's current version was not designed for this purpose. Ordinals and inscriptions as a concept are very new. Using the Casa app to store and send your ordinals / inscriptions comes with risk, and you should evaluate those risks and test the Casa app thoroughly before deciding to use the app to secure your inscriptions.

If you are not a Gold member yet, sign up to get immediate access to Casa's 3-key vault. Download the app, set it up using the instructions below, and get ready to secure your inscriptions!

In addition to the mobile app, you do need to have a compatible hardware device and computer system in order to fully set up your vault with your hardware device as one of the three keys securing your ordinals.

You'll also need to set up your hardware key (initialize the device) prior to adding it to Casa. If you already have a device set up, you can use it with Casa. We have some helpful resources for this in our Hardware keys section, depending on which type of hardware device you're using. 

First, we'll set up the mobile key.

Tap "Connect" in the middle of your 3-key vault.

Next, tap "Set Up Mobile Key."

This will create a key directly on your mobile device in its secure enclave. This is one of the keys that you will normally use to sign and send transactions.


You do have the option to add a second hardware key instead of using the mobile key. To see which setup is right for you, see our article on Choosing your 3-key vault setup.

Next, we'll set up your hardware key.

Your hardware device will first need to be initialized. If you haven't already initialized your device, do that now. You will need to initialize your hardware device by following the instructions given in the packaging of your hardware device. We have a section in our knowledge base dedicated to hardware device setup available to you. 

NOTE: If you have a hardware device already set up and already in use storing other funds, you can still add it to Casa as one of your keys without affecting the other funds. If possible, however, use a unique device that is dedicated to your 3-key vault.

Once your hardware device has been initialized, you can tap "Set Up Hardware Key" in your key list, select the device you'll be using, and follow the instructions to link the hardware device. Depending on the device you're using, you will either get an email sent to from Casa requesting that you "Connect your device" to a laptop or desktop computer, or you'll follow the steps to add the device by scanning a QR code in your Casa app.

To view details on how to add your specific device, find your device in Adding hardware devices to Casa.

Example web flow for Ledger. Your signing experience will vary based on your specific device.

Finally, set up the Recovery Key.

Tap "Set Up Security Questions."

During the process of setting up your Recovery Key, you'll set a series of three security questions and answers. The answers to the security questions should be something that only you know, but something you'll be able to remember. We recommend storing these answers in a password manager.


If you ever need to use the Casa Recovery Key, you'll need to answer all of these questions exactly as they were written during this setup process, including capitalization and punctuation.

Review your completed 3-key vault setup by tapping the "Healthy" button below the vault, then tapping mobile key and hardware key to perform a health check.

The Gold membership allows you to have one "subaccount" for your vault. Subaccounts in the Casa app allow you to have multiple multisig vaults within a single Casa account. 

For those using Casa to store inscriptions, we recommend adding and storing your inscriptions in a subaccount. This will allow you to keep the UTXOs containing your ordinal sat(s) separated in different pools. 

See: Subaccounts in the Casa app for instructions on creating a subaccount for your Casa vault.

Now that you've set up your 3-key vault and created a subaccount for that vault, you're now ready to store ordinals, inscriptions, and, of course, bitcoin.

It's very important that you understand how UTXO management works within the Casa app, so please see our article How to secure and send bitcoin ordinals and inscriptions prior to depositing any ordinal assets.
