so I'm using version 1.3.3.6... how do I enable that thing where my keys are saved by a set of words that I memorize? Is that ready yet?
It's ready here are some instructions posted a while ago by one of the devs.
** ALWAYS BACKUP WALLET.DAT FIRST **
STEP1
1. Save your wallet.dat and rename it.
2. Load the new Shadow Latest client
3. Create a new HD Wallet (Options --> Key Management --> New Key) - give it a "name".
4. Goto Key Management --> Advanced Management and make sure that the new "name" account is showing as "default".
5. The wallet will have pre-generated a Default normal and stealth address
6. Send some funds to test (from your old wallet)
So now I would suggest you try a restore of this account to test it!
STEP2
1. Save your wallet.dat and rename it.
2. Load the Shadow Latest Client
3. Goto (Options --> Key Management --> Restore) - complete steps
4. Goto Help --> Debug --> Console and type "scanforalltxns 590000"
5. You should see your test transaction show up.
If all works, you know you have the correct mnemonic and can then go back to your old wallet and send all your funds to the new wallet.
Your new HD wallet is setup and the mnemonic sentence + optional pass-code is all you need to access all new addresses.
