I have a secret key pair (from a wallet.keys file or derived from a seed-phrase).
I'm researching the subaddress recovery process from those keys.
I heard about BIP32-similar methods in Bitcoin. I know the gap-limit concept.
How does the Monero recovery process work? Does my Monero node go over every subaddress until it found N empty (without transaction) addresses in a row?
How does it work if I have 10000 empty addresses and use the 10001-th? How does it work if I use multiple accounts? Should I save anything else for backing up my wallet in this scenario?
