hi

my friend he said have only first and last words from electrum

the one in middle he dont have


what app is used to recover brute ??

since he have last words ca be easy to simple try many last word is checksum so ...

You can try the FinderOuter (https://github.com/Coding-Enthusiast/FinderOuter). The GUI is relatively simple, read the quick guide in github. With only 1 missing word, it should take few seconds. Alternatively, use btcrecover (https://btcrecover.readthedocs.io/en/latest/); note that it's harder to setup and use than FinderOuter.

Edit: I assume you're just missing 1 word. Your English aren't the best as BitMaxz says.

Do you mean only one word is missing? If you know the exact position of that word then finding the correct one shouldn't take more than a milliseconds using any automated tool. You can even do it manually.
If there are more than one word missing or you don't know the exact position then you can try FinderOuter as suggested above by BlackHatCoiner or BTCRecover (you can read about how it works and how to use it from here:https://btcrecover.readthedocs.io/en/latest/). For both tools, knowing one of the children private keys or addresses will help to speed up the recovery process.

Next time if you don't know how to speak English I suggest you use a Google translator so that we can understand a bit what are you talking about.
I'm a bit confused it seems that you have 3 missing words the first, middle, and the last word, or does your friend only have 2 words the first and the last word?

Anyway, I think all you need is already posted above.

What I would you to do before you use those tools above after downloading them make sure to run them offline or run them on an Airgapped PC for safety purposes.

my friend have missing 3 words in middle

using tool will be slow


i think if there is a script who will brute the middle words... and at same time check the last word generated
if word== word then brute ok

Does it seem you didn't click the link provided by BlackHatCoiner?

The FinderOuter (https://github.com/Coding-Enthusiast/FinderOuter) is what you need just ask your friend if he knows his BTC address with balance.

If you don't know how to click the link then this is the direct link https://github.com/Coding-Enthusiast/FinderOuter then read the quick guide.

And what are you talking about "using tool will be slow"? Do you mean that the FinderOuter tool is slow? It seems this tool currently does not support GPU so the speed depends on your Ram and CPU.

Finder-outer can find it within an hour even with only CPU (unless your machine is 10-years old or more).
3 out of 12-words will only have 8.5 billion permutations.

The condition is you must know any associated address and its full derivation path.
e.g.: the seed phrase's first address = m/0'/0/0, second address = m/0'/0/1, third address = m/0'/0/3 and so forth.

Electrum's last word isn't a checksum, the whole seed phrase is computed to check if the result's prefix is a valid Electrum "version number".
Anyways, that's not the info you want to focus on.

What do you think these tools are if not a brute forcing script? These will be the fastest way to attempt to recover your seed phrase.

If you don't know one of the addresses and its derivation path from the wallet, then you should use btcrecover with an address database instead: https://btcrecover.readthedocs.io/en/latest/Creating_and_Using_AddressDB/

i want this script but in php/js/python

Maybe this is what you want? https://github.com/iancoleman/bip39
From what I see it may be in js (just watch for the libraries too). You can look to actual site for tests: https://iancoleman.io/bip39/

Which part, exactly? For javascript, use bitcoinjs (https://github.com/bitcoinjs/bitcoinjs-lib) or iancoleman that's said above. For python use bitcoinlib (https://pypi.org/project/bitcoinlib/). For php, don't use any libraries, because they're too old and perhaps deprecated. For something specific, pay a Bitcoiner to do the job.  :)

Why?
Electrum's seed phrase isn't even BIP39, it has its own seed phrase implementation.
Also, that can't be used to recover missing words from your seed phrase, it's for converting 'entropy' into 'seed phrase' and 'seed phrase' into 'seed'.

seed phrase = mnemonic
