How to set up a Trezor for multisig

In this section, we'll walk through initializing your hardware wallet, setting up basic security features, and securely backing up your seed phrases. Proper initialization ensures your device is ready for secure key management as part of your Unchained vault.

Already set up?

If you have an existing singlesig wallet that was previously set up with its seed phrase properly documented, review the below steps, check all the necessary boxes, and proceed to the next section.

Video walkthrough

1

Open the box and familiarize yourself

Open your Trezor’s box and familiarize yourself with its contents. In the box, you’ll find:

The device itself
USB cable
Seed phrase booklet(s)

2

Download Trezor Suite

Download Trezor Suite to get started with your Trezor device. Simply head over to trezor.io/start and follow the download instructions. Once downloaded, open the file to install the program.

Only download Trezor Suite from Trezor’s website

You should only download the Trezor Suite from the official website. There are many fake versions, so do not download it from a third-party app store. If anything looks suspicious, call Unchained at +1 (844) 486-2424.

4

Install Trezor firmware

Your device ships without firmware pre-installed, so Trezor Suite will prompt you to install firmware upon initial setup. Click Install firmware.

When the firmware is finished installing, select Continue.

Authenticity check and device tour

If you have a Trezor Safe 3 or Safe 5, proceed through a quick authenticity check followed by a brief tour teaching you the basic operations of your Trezor.

Create a new key

After firmware is installed and you have taken the device tour, select Create new wallet.

For the purposes of this guide, you’re creating a key

When you select Create new wallet, you’re generating the private key that helps protect your bitcoin. While the Trezor Suite will automatically create a singlesig wallet, you won’t need to use it. The key can also be used for multisig as part of your Unchained vault!

Choose a “legacy” backup type

When you see backup type, always choose a 12 word or 24 word backup. Avoid single-share or multi-share backup types that have 20 words. Learn more about our backup type recommendations and how to choose the correct option.

Select Confirm on the Trezor device screen. Finally, in the Trezor Suite, select Create backup.

6

Back up your seed phrase

Your seed phrase words should never be shared with anyone or stored digitally. In this section, you’ll write them down for maximum security.

Things you’ll need for this section

Your Recovery Seed card
A pen or pencil
A private setting in which to perform these steps

1

Check each box to confirm you understand the warnings on your screen. Read them carefully.

2

Select Begin backup and look at the screen of your Trezor.

3

Write down the first word of your seed phrase backup in the first numbered space of your wallet backup card.

4

Take your time carefully writing each word in its corresponding numbered space.

5

Double check the words or perform the multiple choice quiz, depending on your device model.

The order and spelling matter most

The order and spelling of the words matter, but capitalization does not. It’s possible you will receive the same word more than once. If your booklet has space for 20 words while your device only provides 12 words, that's fine—ignore the unused spaces.

Set up a PIN

In Trezor Suite, select Continue to PIN and then Set PIN. Enter your PIN on the Trezor device, and select Continue.

Different devices, different PIN setups

Model One: Look at the numbers on the device screen and locate the number you want to choose for your PIN. Then, click on the dot which is in the same grid position. Your Trezor device is the map for what the dots on your computer screen represent.

Model T: Use the touch screen on your device to enter the numbers. When you’ve entered the final number of your desired PIN, select the checkmark on the touch screen.

Safe 3 (shown): Use the buttons on your device to scroll through the numbers. Pressing both buttons at the same time will select a number and add it to the PIN. When you’ve entered the final number of your desired PIN, scroll through the options to find Enter and press both buttons to finish.

Safe 5: Use the touch screen on your device to enter the numbers. When you’ve entered the final number of your desired PIN, select the checkmark on the touchscreen to finish.

Once you’ve entered your desired PIN, proceed to enter the PIN a second time for confirmation. Click Continue in Trezor Suite.
