-snip- Wallet menu > information will probably tell you how many seeds it has.
The "
Wallet->Seed" menu only shows the wallet's main seed phrase, the cosigner's seed can be seen in the wallet file (
if unencrypted) instead.
I don't think there are any mistakes made during creation if all addresses across all four wallets are the same right?
Since those are in an "
Air-Gap" laptop, do this experiment to make sure:
- Open 'Wallet C' and remove its password by setting a blank New Password in "Wallet->Password".
- Then find the Wallet C's wallet file in 'wallets' folder inside Electrum's data directory (location), open it as text.
- Find the strings "x1", "x2" and "x3" which represent the three cosigners.
- Check if 'x2' or 'x3' of Wallet C has a seed or xprv key (should be "null") because if it has,
it can sign the transaction by itself and you've made an error during wallet creation by providing it with a seed or a private master key.
