So I added a 25th word to my seed, forgot it, and am (after 6 months of on and off guessing) relegated to brute force (3rdIteration/btcrecover).
Succinct question: what derivation path should I specify in the --bip32-path argument?
Hardware: Original Trezor
Wallet creating software: Electrum in 2017
Wallet setup: 2o3
Wallet current software: Electrum in 2021
the mpks are known
Electrum 2021 shows:
- script type, p2sh
- cosigner 1 [HW] trezor1 m/45'/0
- cosigner 2 [HW] trezor2 m/45'/0
- cosigner 3 unknown unknown.
- addresses, previous sends, balance (though maybe these are stored and not derived??)
I am trying to crack cosigner 2.
It is possible I copied the mpk from an old wallet so I am questioning the guarentee that m/45'/0 is the correct derivation path. This is a multisig wallet. In electrum the walletinfo pane lists a derivation path of m/45'/0. Is this a derivation path I can use to crack my xpriv > xpub? Or is this misleading me and is instead a derivation path from xpub x 3 > multisig addresses (in this case my xpriv > xpub path could be anything)?
I've gone through most of the character spaces which I think my passphrase could occupy so I am hoping I am doing something wrong or the transition from 2017 to 2021 electrum has introduced a variation I have missed.
Any tips on what to double check? Notably this post lists m/44'/0/
