Hello,

I have used Atomic Wallet on my laptop, unfortunately I did not saved my 12-word recovery phrase. (Yes I am dumb). My laptop crashed suddenly and I had to do a reinstall of windows. I have not used this wallet for a while until one person sent me a lot of money, even I had new wallet..

1) I used laptop 3-4 weeks after reinstallation so recover data is probably poor chance, plus I use SSD, not HDD, so I probably overwritten the data already.

2) As I researched I believe the only chance is Check mnemonics to get 12 phrase recovery?:

There are 2048 words https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

I need to recover my 12 phrase recovery, I know my wallet address, but I can not remember any word that was in my 12 phrase recovery.

You look up the word's index in the dictionary I linked above to convert it to a binary number, then you run the BIP39 algorithm, which converts a number to a private key, then you use that private key to generate the address (https://www.freecodecamp.org/news/how-to-create-a-bitcoin-wallet-address-from-a-private-key-eca3ddd9c05f/) and compare that to the known address.

Practically: you just have to run the specialized software. Either Hashcat (hashcat.net), or this https://github.com/johncantrell97/bip39-solver-gpu

The hashcat command will probably look like this:
hashcat -a 3 -m 11300 wallet.dat

I need that a company or someone that knows who has super computer like google has it, to recover my 12 phrase recovery..

Let me know your thoughts, possibilities or any other ideas, I know the password of my wallet btw.. Transactions.. Wallet Address..

Who can help me, I will honor 2k$ ..


Thank you.
