Introduction

Hardware wallets offer you the security of storing your keys in secure device while still allowing you to make simple transactions through a web interface.

Trezor

Developed by Czech startup SatoshiLabs, the $99 device is essentially a USB dongle designed to add an extra authentication layer to all outbound bitcoin transactions. Trezor has supported SmartCash since 2018.

By virtue of its design, Trezor can be used to sign transactions on ‘unsafe’ computers and is impervious to keyloggers and many other vectors of attack, so even if your host PC is compromised, the attacker has no way of getting your private key. That’s also where the device gets its name, as ‘trezor’ translates into ‘vault’ in most Slavic languages, including Czech. A kind of ‘vault’ for your private bitcoin key, Trezor claims to use a number of clever tricks to maintain security even on compromised and unsafe machines.

It is also possible to operate a SmartCash Smartnode using your Trezor. See here for details.

Getting Started

Once you have bought your Trezor from https://shop.trezor.io or an authorized reseller, you will need a wallet to use it with. Trezor supports the following SmartCash wallets:

This documentation describes how to get started using the official Trezor web wallet at https://wallet.trezor.io. Always confirm the URL is correct and SSL encryption is enabled when working with the Trezor Wallet. Follow these steps when setting up your Trezor for the first time:

  1. Inspect the packaging for tampering. There should be two seals and the flaps should be glued shut. It should be impossible to remove the device without totally destroying the packaging.
  2. Go to https://trezor.io/start/ and watch the video to introduce the concepts of a shifting PIN layout and recovery seed.
  3. Go to https://wallet.trezor.io/ to begin the setup process.
  4. If not already installed, install the Trezor Bridge application from https://wallet.trezor.io/#/bridge
  5. Connect the Trezor to your computer when prompted.
  6. If this is the first time you connect your Trezor, you will be prompted to install firmware. Click the Install button, wait for the download and confirm on the device.
  7. When complete, the device will display a fingerprint. Verify that this matches the fingerprint shown on the screen. Note that this is hexadecimal and therefore not case-sensitive.
  8. After verification is complete, disconnect and reconnect your device. Enter a device label on the screen that appears.
  9. Enter and confirm a PIN by clicking on the squares according to the mapping shown on the device.
  10. Your Trezor device will now display a sequence of 24 words on the screen. This is your recovery seed. Write the words down in the order they appear on the recovery card. Never store your recovery seed in any digital format, including photos or text.
  11. Verify the seed against what you have written down and store it in a safe place.
  12. You will be asked to enter your PIN again.
  13. The Trezor Wallet will appear with a message that your device is ready for use. Your device name will appear on the device.
  14. Switch to the SmartCash wallet using the menu at the top left. You can now use your Trezor to send and receive SmartCash.
