1  Bitcoin / Electrum / Electrum 4.2.2 2-of-3 multisig: sign transaction with remote wallet? on: June 03, 2022, 03:59:05 PM
Hello -- two questions about using the 2-of-3 multisig in Electrum.

Given three (3) people in three (3) separate locations, each with a Ledger Nano S hardware device -- I will call them Person Orange (with an orange-colored Ledger), Person Green (with a green-colored Ledger), and Person Black (with a black-colored Ledger) who are all in contact with one and other but are not physically in the same place.

Question 1: Is there a way to create a 2-of-3 multisig wallet in Electrum in this situation?

I have created a 2-of-3 multisig wallet in Electrum when holding all the hardware devices myself, but not when they are all in different locations.

Question 2: Is there a way to sign a transaction in a 2-of-3 multisig wallet in Electrum when all hardware devices are in separate locations?

Along the lines of question 1, suppose Person Orange and Person Green want to send bitcoin out of the wallet but they are not in the same location. Is this possible?

Thank you so much for your help! -Dan
2  Bitcoin / Electrum / Electrum 4.1.5 multisig 2/3 - can only send BTC with wallets in specific order on: March 18, 2022, 07:26:17 PM
Hello,

I created a 2/3 multisig wallet using Electrum and 3 Ledger Nano S devices as a test, using them in color-coded order (1) green, (2) orange, (3) black to set the wallet up.

The 2/3 multisig wallet receives bitcoin as expected, but when I try to send bitcoin most attempts fail -- the only successful combination is (1) green then (2) orange, the same first then second combination I used when configuring the wallet initially.

Starting with orange fails immediately and starting with black fails immediately too. Starting with green works partially with a success message after the green verification, but if I attempt to use the black device second it fails.

This is the error message:

Electrum cannot pair with your Ledger. Before you request bitcoins to be send to addresses in this wallet, ensure you can pair with your device, or that you have its seed (and passphrase, if any). Otherwise all bitcoins you receive will be unspendable.

What do I need to do to ensure that any 2 of 3 hardware devices used for the initial setup can be used to send bitcoin?

Thanks! -Dan
