Hello everyone. ask for help.

About 3 months ago I sent from the exchange to the wallet trust wallet 6.41 eth, the address is available, only when I wrote down the seed phrase, I did not give one word, most likely the last, because after 11 words is a comma.

 I don't know how I managed not to write it down, I'm still torturing myself... Besides, this money is not mine, I was asked to help buy ether.

 The main question is: are there any ways to choose the last word? Can be any scripts, programs, brootforces and so on. And another question: how can I most easily restore myself (that is, pick up the word), for example in iancoleman insert the last word and check the address, how to try to automate?

Please help. Thank you very much for your understanding and support.

I don't know if trust wallet uses bip39 mnemonics or no.
If it does and you are 100% sure that the missing word is the last one then there are good chances to recover your wallet (2048 different possibilities).

Here is the word list for bip39: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt
Try each word in that list. There are many scripts you can use to automate the process.

The main question is: are there any ways to choose the last word? Can be any scripts, programs, brootforces and so on. And another question: how can I most easily restore myself (that is, pick up the word), for example in iancoleman insert the last word and check the address, how to try to automate?
Yes. Trust wallet appears to use BIP39 compatible 12 word seed mnemonics, and also appears to be using standard BIP44 derivation path (m/44'/60'/0'/) for determining your ETH address.

This means that you can use the "seedrecovery" script that comes as part of the "btcrecover" package to bruteforce the correct word... It will require you to download and install Python and a couple of libraries... but isn't super complicated if you follow the installation instructions carefully.

The main requirement is that you know what the ETH address used was... if you know the ETH address, the script will find the missing word within seconds.

I've just downloaded Trust Wallet, created a test wallet and got the 12 word seed. I then tested running seedrecovery using the "Ethereum Standard BIP39/BIP44" option, along with the ETH address from the wallet and only the first 11 words... and it found the missing word in a matter of seconds. So, I would say that chances are very good that it'll work for you... assuming you have the ETH address.

Feel free to ask here or via PM if you need help setting up btcrecover/seedrecovery.

Thank you very much, I will try to do it today, I will let you know about the result!

Im glad you found the answer and want to see the result as well.
If i were you, i would frustrated as well because done such simple mistake. I hope you will be succeed to recover your ETH, good luck.

If you think it is probably the last , you just need to brute Force it.
https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

There are 2048 possible words, which are listed in the above link. There are programs already mentioned here that will brute Force for you.

Just the other day I got into the same situation. I was helped by the method that HCP described in detail. After you try, tell me how it went.

No... Guessing one word out of 12 is fine... Assuming you know an address that is fairly close to the beginning of the derivation path... AND the words you have are in the correct order.

Anything additional to that and the time required to generate and check combinations starts to increase at an exponential rate.

Even if you know the words are in correct order:
Time to find One word - measured in seconds
Time to find Two words - measured in minutes/hours
Time to find Three words - measured in days
Time to find Four words - measured in months
Time to find Five words - measured in years
Etc etc

If you don't know the order is correct... These times become orders of magnitude greater.

To brute force 12 words? Measured in lifetimes! Tongue

unfortunately the best way to recover a wallet is through the private keys or mnemonic phrase. thats why its the most important thing to do when openning a wallet to keep it save. probably you can try to quess the word or import in trust wallet. never make this mistake again.
