No functions for other coins - to reduce risk and simplify usage.

You can view a comparison of the features of each Bitcoin-Only Hardware Wallet model in the table below.

Getting started with a Hardware Wallet is not difficult. Let's look at the simple steps using Trezor as an example:

Check the device: Ensure the package shows no signs of tampering or alteration.

Create a Wallet: The device will provide a seed phrase (12-24 words). This should be written down and stored in a secure location, such as on paper or a metal plate.

Set a PIN: To prevent unauthorized access to the device.

Test transactions: Send Bitcoin to the Wallet and then try sending it out to ensure everything works correctly.

Store securely: Never save the seed phrase digitally or take a photo of it. It should be kept hidden in a safe place.

If you're using a standard Trezor model and wish to make it Bitcoin-only, you don't need to buy a new device. Trezor allows you to easily switch from its Universal Firmware to Bitcoin-Only Firmware via Trezor Suite, without needing any special skills. This gives you the same experience as using a dedicated Bitcoin-Only Hardware Wallet, and you can switch between Bitcoin-Only and Universal Firmware if desired.

🔄 Converting a Regular Trezor to Bitcoin-Only Firmware

Connect your Trezor to your computer and open Trezor Suite.

Go to the firmware update menu. The system will display an option to install Bitcoin-Only Firmware.

Select install and follow the on-screen instructions.

Restart the device. Once installed, your Trezor will be a Bitcoin-only version.

✅ High Flexibility - You can switch back and forth. If you want to return to Universal Firmware in the future, it can be easily done through a firmware update.

✅ Latest Updates - Firmware updates from Trezor ensure you always receive new features and security improvements.

🔓 How important is Open-Source?

✅ Coldcard, BitBox02, and Foundation Passport are fully Open-Source, both firmware and hardware.
✅ Trezor Safe 3 & Safe 5 use Open-Source Firmware, but the Secure Element is Closed-Source, meaning Trezor cannot access data within the Secure Element.
