Trezor Model T and ElectrumSV Signature Guide
This guide uses Trezor Model T and Trezor firmware 2.3.0. This firmware allows for Shamir Secret Sharing upon setup of the Wallet with up to 16 shares supported with custom threshold definition.
This guide only covers the signing process. The firmware setup, the wallet setup process as well as transferring some BitcoinSV into the wallet is a precondition to this guide.
Do not use the latest FW 2.3.1 or the signing will not work. It looks like Trezor will fix this in the next release. If you need to downgrade, check this guide.
1. Have Trezor Model T connected and unlocked with PIN
2. Prepare Transaction in Electrum SV
3. Press “Send”
4. Enter your ElectrumSV wallet PW
5. Follow the steps on the Trezor Model T
a. If a path other than m/44’/145’/0’/ is chosen, Trezor asks you to confirm this path:
b. Next, Trezor asks if the amount and address are correct. It will show BCH not BSV. Since these have the same signature scheme, this does not matter and it works just as well for BSV
c. Next Trezor asks to confirm the Locktime in this Transaction, which seems to be set to the latest block (I don’t know why exactly it asks for this but just confirm it, as it is normal)
d. Check amount and fee and hold for final confirmation of signing process.
6. Electrum SV confirms your TX
7. Payment received
