What has changed in this release?

The main changes in this release have been listed below. If you don’t want to know the details, just read the titles. If you want to find out about smaller fixes, you can check the release notes in the Github repository.

Trezor passphrase signing works again

The 1.3.8 release allowed Trezor hardware wallet owners to use Trezor’s latest firmware. However, in the latest Trezor firmware an API changed related to entering passphrases for your Trezor device. Specifically, the API now passed an extra flag into ElectrumSV which indicated if the device supported on device passphrase entry.

Passphrases are a hard to understand concept where you can extend the key securely stored in your hardware wallet device with some extra text. You specify this text every time you set up an account for the Trezor device in ElectrumSV. The theory is that this allows you to create secret stashes on demand for your hardware wallet, just by creating a new account and using a new passphrase.

Thanks to the many users whose names I do not remember who pointed out that this was not working any more.

Trezor passphrase on device now supported

Normally when you enter your passphrase for your Trezor device you do it in ElectrumSV, which is of questionable security. But Trezor support an option to enter your passphrase using an old school mobile style keyboard (do people still use these?) on your Trezor Model T touch screen. I figured that while I was testing the passphrase code, I may as well implement support for this and test it at the same time.

The Trezor Model T needs to know the passphrase.

The Trezor Model T (but not Trezor One) adds the extra shown “On Device” option, and when it is clicked the Trezor device then asks for the passphrase as shown below.

On device passphrase entry UI.

Keepkey and Trezor passphrase confirming uses the correct dialog again

When you create a hardware wallet account, and your device is configured to use passphrases, ElectrumSV would ask you for one on it’s behalf. But the problem was it would use the above shown “Enter the passphrase to unlock this wallet” dialog, rather than the confirmation dialog shown below. This change restores the use of the shown confirmation dialog, which helpfully shows a warning about forgetting the passphrase.

The correct dialog for passphrase entry on account creation.

Remember that Trezor caches the passphrase, so you will not be able to use the Trezor device to sign different accounts until you’ve disconnected it and reconnected it to reset it.

Other fixes

  • #569: If a user had hidden the coin-splitting tab, text from the coin-splitting tab would leak out and be displayed over the “Add Account” button. This only happened on a fresh wallet load with the tab hidden.
