Topic: Seed phrase bruteforce options (Read 144 times)

It's mostly because they did not back up their wallet mnemonic seed, or back it up with bad methods, or back it up inaccurately, and they missed /ignored a vital step:

• Testing their backup for wallet recovery.

Without this vital step, you never know that whether their wallet mnemonic seed backup is correct and useable for wallet recovery.

How to back up a seed phrase?
With whatever backup methods, they must do this step

I still don't really understand the reason why people end of making mistakes with their seed phrases. Nevertheless op you should also get to know that aside from the fact that it's a 12 word seed, it could be either a BIP-39 seed like you mentioned or also a Standard ELECTRUM seed like in most cases. Nevertheless note that they both have different word lists so applying a brute forcing script would also need you to pick the right word list.
Nevertheless the the longer time it would take to brute force the seed phrase is because you don't have the exact position of the last missing word else it would be a lot easier and faster.

Thank you for responses, this solution worked out for me. It had some bugs, but on app developer youtube channel are videos on how to deal with them, when you are trying to recover Solana. Wallet is successfully restored.

Thank you, I will study these materials and try to do the tests.

3rdIteration's BTCRecover fork supports Solana and it can be given a different derivation path in case Phantom wallet isn't using the default.
But with SOL, it requires some dependencies from "requirements-full.txt" to work so use it instead of "requirements.txt" when installing BTCRecover's dependencies.

Read the documentation and make BTCRecover work,
Then try to describe this better or make an example using "word1" ... "word12" texts instead of the actual words:

As Phantom wallet, I never used it, appears to be BIP39 compatible, it should be no big deal to brute-force the missing word in between your known sequence of 11 words.

The last word of mnemonic recovery words according to BIP39 standard, embeds a checksum. When you say, some word in between is missing and the missing word position is unknown, there should be a rather limited amount of possible solutions.

I haven't done this for other coins than Bitcoin, but I assume it should be possible to brute-force the missing word with BTCrecover which can also handle Solana. If you know an address of your wallet, the better!

See here: https://btcrecover.readthedocs.io/en/latest/

You may need to make yourself familiar with the tool. If you know nothing about derivation path and HD wallets, then maybe learn about it at https://learnmeabitcoin.com. You can learn such wallet basics with no issue in the context of Bitcoin, even when your wallet was one with Solana.

I would also recommend to prepare a test case. Create a 12-word BIP39 recovery backup e.g. with iancoleman script. Get an address of that wallet (iancoleman script doesn't support Solana, take some coin that BTCrecover and iancoleman support). Choose a word in between to be the missing one, but you know the solution.

Check if you can recover this word and verify it with the known solution. If you fail with this test case, you likely won't succeed with your real case.

Hello guys!

Long story short. I was stupid enough to write down only 11 words out of 12 of the seed phrase. They were generated automatically, so I suppose they were taken from BIP39 dictionary. At least all 11 words I know are from there. I was using Phantom wallet and trying to recover it there. Right now doing manually, but it's quite a time consuming activity and therefore not very effective.

So I know the 11 words and their order. One word in between them is missing and I don't know on which place this word is.

Are there any ways to automate the process of seed phrase checking? It was a solana wallet, so the wallet to check those words into could be solana compatible.

I am not a programmer, so writing a python application (or similar) and making it work is not an option for me. I'm looking for a solution, than does not require programming skills.

Any help will be appreciated.
