Blockstream Jade allows users to enter the first 11 or 23 words of a BIP39 recovery phrase, and will automatically calculate possible options for their final word. This is especially helpful for users who want to generate entropy manually (such as by rolling dice) to create a recovery phrase, but still need a safe way to calculate valid final word options.
Tip: Check out the recovery phrase creation guide using dice rolls here. Keep in mind that any alternative method that requires final word calculation can be used and this feature is not limited to the method shown in the link above.
Calculate Final Word
1.
Turn on your Blockstream Jade and choose to Initialize and Recover a wallet, or click Advanced and select Recovery Phrase Login if your Jade is already initialized.
2.
From either the Recover wallet or Recovery Phrase Login flow, choose Advanced then select the recovery phrase length you would like to calculate a final word for.
3.
Enter the first 11 or 23 words of your user-generated recovery phrase, then select Calculate. The keyboard for the final word will restrict your entry only to valid options.
Tip: The keyboard for the final word entry will automatically start on a random letter. After choosing 1-2 letters, Jade will display the remaining list of options and will also begin it's selection on a random word. Simply click through the calculation section if you would like Jade to randomly select a final word for you.
