Title: Lost the last word of my Metamask seed (please help) Post by: Cootiepie on February 10, 2018, 07:45:37 PM Hello guys, i somehow lost the last 12th word of my metamask seed , i already used a script to find the missing word , the other 11 words are in the right order
but it found thousands of valid seeds. I know my Ethereum address, is there a script or an easy solution to search through the valid seeds and to find my seed that contains my address and coins? Help would really be appreciated - Cootiepie Title: Re: Lost the last word of my Metamask seed (please help) Post by: overtorment2 on February 10, 2018, 11:04:42 PM Well, making a bruteforcer is rather easy. Brutforcer should not only check the validity of the seed, but also the fact that there are any transactions on derived addresses.
This is pretty trivial, and might be outsourced to a freelancer.

I'm not aware of any tools though so either check manually word by word or take this matter to WalletRecoveryServices.com If you don't mind paying a fee, MetaMask is not listed there but I'm sure they could help.

https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt if you don't know the place of it, the number of possible seeds grow huge because there are simply too many variants. you have 12! possible seeds (479,001,600) only if you know all 12 words (it can be more because my math sucks sometimes). if you also miss 1 it will be near infinity.

Not knowing the last word means 2048 possibles. Not knowing one word or it's position means 2048*12 possibles. Either is easily solvable.

I know my Ethereum address, is there a script or an easy solution to search through the valid seeds and to find my seed that contains my address and coins? I would recommend using the "seedrecover.py" script that comes with btcrecover (https://github.com/gurnec/btcrecover) It supports Ethereum seeds (it even mentions Metamask) and it supports searching by an address... You'll need to have Python installed, then: - Run seedrecover.py - It'll prompt for a "wallet file", click "cancel". - It'll prompt for wallet type, Select "Ethereum Standard BIP39/BIP44" - It'll prompt for a "master public key", click "cancel" - It'll prompt for an ethereum address, enter your address and click "OK" - It'll prompt for the "Address Generation Limit", this is how many addresses it will generate using each valid seed. If you're sure the address you entered is one of the first addresses in your Metamask wallet, I'd recommend using 5 or 10... otherwise bump the number up (bigger limit = longer time) - Finally, it'll prompt for your seed, enter the 11 words that you know and click "OK" Wait a few minutes and it should find your seed. ;) |
