How do I get started with Keymaster?

Ready to get started with 2-of-3 Basic Multisig?  First, sign up for Silver here or Gold here and create your Casa account.

IMPORTANT NOTE: If you've already set up your Trezor, you should transfer all funds off the device, then wipe the device before returning to step 1 below. We always recommend using a dedicated device for your multisig setup.

1) Download the Keymaster App. Download the app Keymaster iOS or Keymaster Android and login with your Casa account to begin.

2) Create your Mobile Key.  First, you will create a key directly on your mobile device. Once this is finished you'll hear a chime and see that the key has changed in the list to a green color.

3) Open and connect your Trezor and go to https://trezor.io/start/.

4) Initialize your Trezor device. Follow Trezor's setup instructions to "Create a New Wallet", but during the "Create a Backup" step we recommend to NOT write down the seed phrase. We've designed our multisig to be seedless for an improvement in usability and security.  If you are using a Trezor Model T, you'll need to write down the seed phrase for the verification step, but then destroy the seed phrase after verifying it. We have a faster and cleaner method of seedless initialization in development.

5) Give the device a PIN number (something you'll remember!) and a name ("Casa Home" or anything else that will help you remember that this devices is being used in your multisig setup).

6) Go Back to the Keymaster App. After completing the Mobile Key setup first, and then Trezor initialization process, you can follow the instructions in your Keymaster app to link the hardware wallet device. 

7) Link your device to Casa. An email will be sent to you requesting to "Link your Device." Click on the "Connect Device" button in the email, connect your Trezor,  export the public key (we NEVER have access to your private key!) and you're finished.

8) Review your completed Basic Multisig 2-of-3. Tap on each of your keys to view public keys, perform a Health Check, or mark a key as compromised (which will begin a recovery process).  

9) Use Testnet Bitcoin to test your setup. We ALWAYS recommend that you test your setup using Testnet Bitcoin before onboarding real funds. You can try signing transactions, flagging keys as compromised, Health Checks and more – all without the risk of losing real funds.  Grab a receive address and go to this Testnet Bitcoin faucet to get some Testnet Bitcoin!

You’ll navigate the Keymaster app with these 2 primary views:

  • Your security view —  shows you which keys are set-up, active, or compromised. This is where you perform health checks and view your security status.  
  • Your assets tab — a view of all the asset balances you have within your different keys (i.e. mobile, multisig). This is where your transactions live.

You also have the Help and Settings tab. Help brings you to your support options, and in Settings you can send yourself sovereign recovery info, allow for log data to be collected, and change your phone PIN security level.
