Backup password

Wallet password

At least 12 characters. A long, unique passphrase protects the encrypted copy in this browser.

Confirm password I have an offline recovery backup for this wallet.

How would you like to create your recovery phrase?

Both options create a 24-word recovery phrase.

Roll a fair six-sided die 100 times. Enter every result in order using the buttons or the field below.

Rolls entered0 / 1000 of 100

Your rolls

Your rolls are mixed with secure browser randomness. Save the 24-word recovery phrase; rolls alone cannot restore this wallet.

Stay on this tab. Leaving it clears setup.

I used physical dice, not numbers I made up.

Write down these 24 words in order. Anyone with them can spend your coins. Kachie cannot recover them for you.

Re-sign unsent reveals

The commit is on the network. This signs new reveal transactions for the parts that did not go through, paid from the amounts already locked (enough for twice the original fee rate). Nothing new leaves your balance. If the network needs more than that, wait and use Retry later: the locked coins stay in outputs only this upload's own key can spend.
