Trezor Model T Setup

This article details how to set up (initialize) your Trezor Model T hardware wallet for use with Casa App (formerly Keymaster).

Note: Casa is not compatible with Trezor Model T firmware 2.3.1, released June 3rd, 2020

To begin, verify the integrity of the device box and the device to ensure that it is free from tampering.

Once your Trezor Model T has been unboxed, remove the tamper seal and head over to wallet.trezor.io in your browser. We recommend Firefox, Brave, or Chrome. You’ll connect your Trezor Model T device when prompted, using the provided cord.

If your device is not recognized once plugged in, head over to wallet.trezor.io/#/bridge to download the bridge.

If this is your first time setting up this device, you'll likely be asked to do a firmware update.

Casa usually recommends getting the latest firmware when initializing a device for the first time, before the key is funded, however the most recent release from Trezor is not compatible with our system. Please do not update your Model T firmware beyond 2.3.0!

Next up, choose “Create Wallet”, and then select “Create with Single Backup”. Accept the terms & conditions, and confirm the action on your device by holding down your finger on the touch screen.

Now, you’ll need to complete the backup process. Choose “Create a backup in 3 minutes”, click the box, and press continue.

Use the device touch screen to scroll through each word on the device, writing them down for confirmation in the next step. Once all 12 words have been written, complete the quiz on the device.

 

 

 

Next, you’ll set the PIN code on your Trezor. It’s very important that you do not forget this! The Trezor Model T will perform a factory reset after 16 failed PIN attempts.

 

If you are using multiple hardware wallet devices in your multisig setup, we recommend using the same a 4-8 character PIN (no zeros) across all your hardware devices, and saving it in a password manager.

 

 

Now, you’ll be asked to name your device. You can choose any name, though for best OpSec practices, we recommend not choosing words such as, “Casa” or “multisig."

 

 

 

 

The final steps will ask you to set up bookmarks, newsletter & social media with Trezor, but those steps you may click through to skip them.

 

 

 

That’s it! Your Trezor Model T is now initialized and ready to be added to your mutlisig keyset in Casa App.

Finally, keep your Trezor somewhere safe and secret. Though there may not be funds in the wallet yet, keeping it secure and protected from tampering prior to funds placement is very important!
