Pleas Help -Lost the last word of 24 seed phrase & 1K

[HeptaSean]

@CryptoCoen

I just created a nami wallet account.

Since you write “just”: Did you use it for anything? If not, you can just delete it and create a new one. It costs nothing.

@CryptoCoen

Wrote only 23 words of 24 word seed phrase. Please help me to recover my account if its possible.

Is totally possible. The words come from a list of 2048 words and contain a checksum that dramatically reduces the possibilities for the words.

I wrote a script to recover them here:

I lost my spending password and phrase seed

I have reimplemented @isferos’ idea in Python 3 for a flexible length seed length (12, 15, 18, 21, or 24 words): It is called with the words that you know as command line arguments and _ as placeholder for words you do not remember. If the last word of a 15 word Yoroi seed phrase is missing, it will give you exactly 64 possibilities (the last word encodes 11 bits, of which 5 bits are checksum, so 6 bits are part of the entropy and 2^6=64). For missing words in other places, the order of magni…

And gave more remarks on how to use it here:

Am I screwed?

It does not need to be changed. The part you know is given on the command line with a _ replacing the word you do not know. (It expects exactly 12, 15, 18, 21, or 24 arguments on the command line, in your case 14 words and _ for the 15th that you do not know.) Attention: Never share the part you know here or somewhere else on the Internet. Even if you can’t crack it now, it might help others to crack it before you. It is Python 3, so you need that. If you are on Linux, it should already be the…

If that’s too technical for you, ask, but don’t expect an answer in minutes.
