Cardano: NerdOut - Key Derivation

Key Derivation is the process a wallet uses to go from a mnemonic phrase to a whole set of keys and addresses that the wallet controls.

Notes: I've received a few comments to stuff the video got incorrect.

1.) S(CHANGE) should be S(CHAIN). "Change" was just used as an example on the page explaining this stuff.
2.) I made a statement about hardened derivation not being able to get public keys and then immediately showed how to get public key from one of them. This statement was obviously not correct.

Great job! I hope you can make such video's with higher resolution in the future, it's quite hard to read the text.

Very good video. Is there a repo with the code you showing in this video? I like to reproduce the steps und understand it better what you showing here.

Great video Andrew, you've saved my life :D I have one doubt related to stake keys. If I can create multiple stake keys related to the same wallet like:

1852'/1815'/0'/2/0
1852'/1815'/0'/2/1

Can I build multiple base addresses using different stake keys? What this could mean? Because in all the examples that I've seen, they assume that we have a unique stake key per account(wallet 1852'/1815'/0') key

Thanks a lot!

Can you share the code repository that you used in the video? The javascript one.

Hi Andrew, the reason one could not restore ADA account from a ledger device in a Yoroi web wallet using the same set of mnemonic is due to the path used in ledger is m/44H/1815H/0H/0 while Yoroi use m/1852H/1815H/0H/0/0, correct?

Andrew i dont suppose you could link your node.js source in the video?

If you receive some tokens, Is it possible to figure out an address to the wallet that sent you some ADA or tokens based on the txID hash?

Crazy stuff. So I have my ada all broken up into so many addresses right now, but it does seem to all be connected to my same stake key. how can I get all my ada into one address now, as this is just gonna cause multiple transactions isnt it? I should have just keep sending to the first address instead of all the new addresses it kept giving me when i was topping up my dip buys..

Fyi the url to your site is not correct. Figured it was 'house'
