For a Ledger Nano S recovery contingency plan, how can one compute an associated vector of 25 Electrum wallet recovery words for each primary address using BIP 44 technology that is seeded from BIP 39 using 12, 18 or 24 seed words (not to be confused with Electrum seed words), and an associated BIP 39 passphrase (not to be confused with a Monero wallet password)?

It is unclear if or how m/44'/128'/0' or m/44'/128'/0'/0/0 or some other HD wallet path(s) is/are used to synthesize a primary Monero private key and associated address.

It should be possible to calculate associated Electrum seed words for a given set of BIP 39 seed words and a specified HD wallet path. Those Electrum words could then be used by monero-wallet-cli to recover funds using --restore-deterministic-wallet, or other wallets (e.g., Monerujo, Cakewallet, X Wallet).

With a Plan B Recovery Plan, it should be possible to engender more trust in a Ledger Nano S beta Monero capabilities. The Trezor had such a Plan B recovery capability 18 months ago before the Monero Ring CT fork activated.

  • Please clarify what you mean by "Plan B Recovery Plan". – jtgrassie Jul 19 '18 at 20:43

  • Looks like something is happening, see reddit.com/r/Monero/comments/95kx37/…. Would like to see the theory before having an implementation. – skaht Aug 10 '18 at 22:53
