Generating Deterministic Polkadot Addresses about hdwallet HOT 2 CLOSED

@farukterzioglu - I am not an expert in these issues, but I can provide two other suggestions for places to look for help:

1. make a post on Stack Overflow and tag it substrate
2. open an Issue on the Substrate subport repo: https://github.com/paritytech/subport/issues/new

from hdwallet.

If you are using the standard mnemonic -> seed as per eg. ETH/BTC it won’t match.

Substrate goes from mnemonic-> entropy and then does pdkdf2 rounds (with the ///password and a known prefix) to get the private key (mini secret in Substrate terminology)

The outputs are vastly different between the 2 approaches so even something with no derivation will not match.

Trivia tidbits -

• Around poc-1 the first approach was still taken in Polkadot, it was changed in poc-2 for better use of the available material
• Ledger keys are derived like yours, so non-Substrate-matching, but obviously still works since the crypto is ed25519 and supported
