Hi Everyone,
Newb here, and orientating around this forum at the moment.
I've read some posts about restoring your wallet by using your passphrase combination in conjunction with seed (words). I'm wondering how does this restoration actually work, and what does the seed do exactly in this process?
Is the seed a (unique) combination of words that, together with your passphrase, provide you all the info you need to restore a wallet on any device? Like seed + password combination?
Or how does this string of information fit in the process? Or how is it used in the process of actually restoring a wallet?
Thanks in advance for any responses.
Cheers
First of all: welcome to the forum.
I immediately want to correct your assumption: the MOST common HD wallets need ONLY the seed phrase, there is no need for the passphrase.
The seed phrase is used to create an xprv. Using a derivation path, private keys, public keys and addresses are derived from this xprv.
