Recovery of ETH address from deprecated wallet

Brave Wallet (Self Custody)
1

Hi all,

I am trying setup and recover BAT on a new Brave browser installation

Mac OS 14.3.1
Brave: 1.64.109

with a seed phrase created by Brave browser ver: 0.70.121

Using the Default Ethereal wallet - Extensions (Brave Wallet fallback)
Import existing wallet → Restore from seed phrase (WITHOUT Import from legacy Brave crypto wallets selected)
I get this ETH Address: 0xD886BC5860c72C11300660cbBa1ad7e77C1603b5

Using the Default Ethereal wallet - Extensions (Brave Wallet fallback)
Import existing wallet → Restore from seed phrase (WITH Import from legacy Brave crypto wallets selected)
I get this ETH Address: 0xCC12A617635B314e259508Bc437AbC63aa78EC9d

Using the Default Ethereal wallet - Extensions (Brave Wallet fallback)
Import existing wallet → Import from legacy Brave crypto wallets
I get the same ETH Address: 0xCC12A617635B314e259508Bc437AbC63aa78EC9d

Using the Default Ethereal wallet - Crypto wallets (deprecated)
Import using account seed phrase
I get the same ETH Address: 0xCC12A617635B314e259508Bc437AbC63aa78EC9d

Problem is that the address I see in my original records and transactions from when I first bought the BAT the address is: 0x604abc0c2Ab0D0B7844c2d1dda86cfd3B5926D4d

My original brave browser 0.70.121 on old hardware hangs when trying to open the crypto wallet otherwise I would export the private key and add the account that way but that doesn’t seem to be possible unless I can repair this installation.

Is there a different legacy version of 24 word seed phrases from version 0.70.121?
I noticed that there were also Niceware 16 word seed phrases used at some stage and a tool to convert these to BIP39 https://jonathansampson.github.io/brave-tools/bip39-from-niceware/

Thanks for any help you can provide.

@steeven and @Evan123 wanted to tag on this so you can follow-up if nobody has sent DM. Not sure what help can be provided, if any.

Thanks. Haven’t seen anything yet.

I understand how you get 2 different HD address trees from the same seed phrase depending on the standard used (BIP39 or Brave Legacy). What I can’t understand is where the 3rd HD address tree (which happens to have my funded address) was generated from.

I’ve still got the old MacBook with the original wallet (Ver 0.7.121) that generated the seed phrase and address tree but it seems to just spin forever when trying to access the crypto wallet tab, I’m guessing due to changes to the rewards server back end.

Pity I only recorded the seed phrase and not the private key!
