2  Bitcoin / Hardware wallets / Re: trezor + metamask on: April 17, 2024, 10:41:55 AM
Hello everyone, first of all i hope this is the right section.

I have a few questions about the connection between trezor and metamask.
Few years ago i connected my trezor with metamask, but i really don't remember which steps i did.

In this video (https://www.youtube.com/watch?v=67hkAEcEH1o) i see that it's very important not to do "import wallet" but instead "create new wallet".
I don't remember what i did in the past, but, right now, what i should do?

Right now, in my trezor suite i see my eth, but not my tokens...

Thank you very much!

The safest way is to connect the Trezor from the connect hardware wallet pull down menu.

Choose the first account, and then at bottom choose connect hardware wallet.
No need to enter seed, only confirm with your trezor PIN.

Whenever you want to send funds out, you confirm with trezor plugged in, and no need to enter passphrase.

Also, to see then tokens, you need to add the token contract manually.

Easiest to do so is to go to etherescan.io, enter you erc20 address and then from the pulldown menu choose the token you want to add
When token is chosen in your browser, copy the contract and paste it into Metamask. You do that with Import Token menu second from bottom

You should see the tokens then. If other chain than ETH need to change chain first. Takes a few seconds to sync, then they should show up.

Good Luck!

This is actually not correct, you need a WALLET ID which is xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx
Can you access your wallet on blockchain.com if all you have is the wallet ID and you don't know the password?
For logging into blockchain.com, you should use your wallet ID instead of your email address, but you still need your password and you still need to authorize your login via your email address.

There are various scenarios with various options, but if you have wallet ID to start, you can access and download the encrypted backup like here
https://btcrecover.readthedocs.io/en/latest/Usage_Examples/2020-05-08_Recovering_Blockchain_Wallet_Passwords/Example_Recovering_Blockchain_Wallet_Passwords/

If you have 2fa activated (not everyone does) it is needed to either use the phone app or mail, in case you lost the 2FA, it is still possible to reset it using this link
https://support.blockchain.com/hc/en-us/articles/360000286426-How-do-I-disable-two-step-verification-2FA

Of course if you dont have anything, nothing is possible.

Then if you managed to download the payload for the wallet, you can use various tools like btcrecover, johntheripper or hashcat to bruteforce the password. Of course having any idea of the password helps.

If you do know email, but not wallet ID, you can go the other way around and request to get all WALLET IDs associated with that email, you can do this here:
https://login.blockchain.com/en/#/login?product=wallet

Hope this brought clarity to the ways you can recover your BTC from blockchain.com

Good luck!

4  Bitcoin / Development & Technical Discussion / Re: Recover old wallet.dat from blockchain.info on: March 15, 2024, 10:22:10 AM
Blockchain.com or .info are online wallets we do not know what they do to the wallet files you uploaded to their site even if they have your wallet.dat or not I don't think they will let you have it.
That’s why I asked at the beginning of the topic if there were blockchain representatives here.

If you accidentally deleted the wallet.dat have you tried to use some recovery tool like Pywallet? It can recover deleted wallet.dat.
It was deleted a long time ago and has already been overwritten with new data.

Or alternatively, if you still have the wallet.aes.json file use the link below to recover your wallet.
I have this wallet.aes.json, but it only contains addresses, without private keys.

No one from blockchain will ever write to you here, they only go through the original blockchain.com webpage.

You can ask for support here: https://support.blockchain.com/hc/en-us

Knowing a bit how blockchain.info used to work, it all depends if you migrated to a new wallet ID or kept the same.

Also, did you ever keep the original wallet.aes.json file?

When you remove addresses/keys from the wallet, they sometime create a new wallet ID, and the new ID has only the requested data. So if you ever saved an old wallet.aes.json file or kept the original wallet ID you might be in luck.

The way the server works if you didnt login for a lets say blockchain.info v1 account since 2014, they still have that original wallet, but if you logged in and did transactions, its upgraded to v4 (March 2024) and has a totally different encryption and format.

If there is anything else try the support link above.

Good luck!

5  Bitcoin / Bitcoin Technical Support / Re: I need help please, to get back into a Bitcoin account. on: March 15, 2024, 10:15:05 AM
For accessing your wallet on blockchain.com, you need your email address plus the password or your seed phrase.
If you have neither the password nor the seed phrase, there is no way to access the wallet.


We do have a # code for wallet, but not sure if this is for his new account to try to import the old one, but without a seed phrase it seems it will be a next to impossible task.
I don't know what code you are talking about, but whatever it is, that's probably useless.
As I said, you need to have the password or the seed phrase.

This is actually not correct, you need a WALLET ID which is xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx

So telling this person there is no way to access the wallet if email and pass is gone is wrong...

7  Bitcoin / Bitcoin Technical Support / Re: Problem with unknown address on blockchain on: March 13, 2024, 10:47:47 AM
Hi everyone, I'm new here.
I have a problem, I made a transfert from Ledger to Binance, and I send some BTC using the Binance address
The problem is that only half of amount arrived.
When I look at the blockchain, with the TxID/TxHash, it says that my transfert goes to 2 addresses
first half to the Binance address which appears in my Ledger operations (1MLF...) and this part has arrived in Binance
But the other half went to an address I have no idea of (bc1qdz...) and here are my second half of bitcoins.
I don't understand, and I don't know how to get them back?
I'm stressed...
Thank you for your support and sorry if it's not the right part of the forum to post that.

You need to add addresses to your ledger and the missing (chaange) BTC will show up.

Good luck

8  Bitcoin / Bitcoin Technical Support / Re: Missing last 7-9 digits of Blockchain's second password on: March 13, 2024, 10:45:37 AM
Hi,

So I know the first nine characters of my second password,  know exactly which one of the letters are capitalized, the last two of the first nine characters are numbers, oh and the missing 7-9 characters do contain duplication of a digit.Tried these password hints with wildcards, but btcrecover only tries 4 or 5 iteration:
^1^ASDFGHj
12%7,9d
Do I need to include typos? Any help will be greatly appreciated.

Hi, Its better to extract the hash and use hashcat. You can find it here: https://hashcat.net/hashcat/

Looking at your password ^ is a character that sometimes gets interpreted differently depending on your keyboard setup.

If you want to stick with btcrecover try  --typos-insert and --max-typos-insert

Good luck!

According to your site[1], the services you provide are

Quote
Trezor Passphrase lost.
Ethereum Presale password recovery.
Geth password recovery. GETH.
ERC20 Tokens from Metamask.
Bitcoin from Multibit Classic.
Your Dogecoin Core or Langerhans wallet.
Blockchain.com first or second password.
An Android wallet or spending PIN.
Ethereum password from JSON file like MIST.
Blockchain.info mnemonic or seed words.


I have checked your positive trust and they are all related to translation services that are not related to what https://keychainx.io/ is trying to provide so unless you explain your service correctly I will ask these members to review their trust and you may give you a negative trust.

If you do not customize your service, such as restoring short Passphrase, less than 5 characters, or missing 2-4 wallet seed words that are in the correct order, then what you are trying to provide is a scam.
[1] https://keychainx.io/

Obvioysly you have no idea what you are talking about. We have recovered passphrases which are 15-20 characters, and permuted 24 word seeds , this is not 2012, you can actually do much larger searches than you talk about.

On a simple GTX 4060 card you can do up to 8 characters in a day or less for missing passphrase, so we are not talking cpu recovery.

And looking at your positive feedback, it does raise some eyebrows...

Would you be able to help with a lost password to Electrum? I only remember part of my seed phrase too, which seems to be an issue with the recovery Embarrassed

Do you know the address of the funds?

13  Bitcoin / Bitcoin Technical Support / Re: Bitcoin core, (wallet.dat) on: January 26, 2024, 08:37:27 AM
Hi I have came across a few old wallet.dat files on my PC.

After letting Bitcoin Core sync for 24 hours, the program is now ready.

I have a few questions.

I have pasted the file inside of this directory
C:\Users\Admin\AppData\Roaming\Bitcoin

I then opened BTC core and did the following:
File > Restore Wallet > C:\Users\Admin\AppData\Roaming\Bitcoin\wallet.dat

It the asked for "Wallet Name" I just entered anything.

After this I had the error:
Wallet loading failed. Wallet files should not be reused across chains. Restart bitcoind with -walletcrosschain to override.

I'm wondering do I simply just add the this (-walletcrosschain) or am I importing the wallet incorrectly?

Any help is appreciated!

Did you try pywallet an open source Python library?

It can parse your wallet.dat without downloading the entire blockchain and export the private keys

You can find it here

If you need a reliable source for your lost crypto wallet password dont hesitate to contact us or read more on our blog

https://keychainx.medium.com


or check website

We can recover "lost cause" from Multibit, Metamask, Electrum, Schildbach and other old wallets.

If you have a Trezor and used the "hidden wallet" feature, we can do that as well.

15  Bitcoin / Electrum / Re: Trojan in Electrum wallet? on: January 26, 2024, 08:30:44 AM
I downloaded a portable version of Electrum wallet from the official website. Checked it with VirusTotal service and one engine showed me that there is a trojan in the wallet. What do you think, is it true that the file from the official site may contain a trojan or is it a false positive of the Ikarus engine?



P.S. The Windows Installer version is clean, but the Standalone Executable version also has the same trojan.
¨

Windows flags several Bitcoin wallets as trojans.
16  Bitcoin / Wallet software / Re: How long to crack 24 word phrase if you know all 24 words out of order? on: September 18, 2023, 04:25:49 PM
I am curious to know the actual difficulty/cost/time involved to put a 24 word seed phrase in the correct order if you have the 24 words but not the correct order? I can see that there are 24^24 number of combinations but what does that translate into difficulty/time/cost?

Not possible today.

We have a custom script for 12 word seed which can crack any combination in 30 days using GPUs

13 words would take 2-3 years, 14 words 100+ years.

So 24 words out of question today

You would also need to know the address

17  Bitcoin / Wallet software / Re: Help identifying old wallet by weird seed phrase on: September 18, 2023, 04:22:34 PM
So I happened to find a seed phrase for an old wallet used to receive the five free coins from the faucet in 2010. Unfortunately I have no clue about which wallet it is.

The seed phrase is only 8 words of 7 characters, and is not BIP39.

After whole lot of googling I encountered this wordlist, and all the words appear there http://rabbit.eng.miami.edu/dics/amerlen/length07.txt Several of the words are not even proper english words, but do appear on that list and nowhere else relevant. The wordlist has 108824 words, and the words in phrase seem to be spread over the whole range.

Will pay 10% for tip leading to access.



Its either a

1) blockchain.info wallet that used to generate a seed for the password
2) Multibit Classic wallet
3) Electrum custom seed

You can download most of these and check what addresses they generate

Good luck!

Greetings ,
Sorry if this question has already been asked , I couldn't find a method to do it , I have an old wallet from 2013 , it is actually an app ( green address) the wallet is currently empty , but I wanted to get the private keys to import the wallet to BitcoinCore , and I only have the 24 seed words .
Thank you

How many words?

More than 12 it could be blockchain.info

If an app, download the latest version, import words, then display private keys (like electrum.org)

Good Luck!

19  Bitcoin / Bitcoin Technical Support / Re: Importing an old v0.3.0 wallet.dat - is my plan sound? on: May 12, 2023, 02:11:05 PM
Hello all,

I have found an old Windows disk backup, on which there is the 0.3.0 version of the bitcoin client which I played around with for maybe a day or two in 2010. The wallet.dat and associated %appdata% files are all there. I’ve made a few off-line copies of everything.

I have some knowledge of GnuPG and Linux (Debian mainly) but I have not used Bitcoin since 2010 so trying to get up to speed with things.

In case there is anything of value in the wallet, I want to be careful. Here is my plan – what do you think?:

1. Download latest Ubuntu ISO using a Linux laptop I have rarely used. Check SHA256 on the ISO.
2. Disconnect all drives from my usual PC (Ryzen 3).
3. Use the ISO to install Ubuntu on a SSD on the PC
4. Install current version of Bitcoin Core using Ubuntu’s own software installation tool.
5. Wait for Bitcoin Core to sync to the blockchain.
6. Import the old wallet.dat, rescan and hope for riches!?

If the old wallet contains anything of value, what should I do next? I gather a cold wallet like Ledger would be sensible, including carefully stored handwritten keyword backups.

Thanks for reading.

None of the above, the quickest way is to download pywallet and you can export the addresses/private keys. then import them to Electrum.

Pywallet Github

https://electrum.org/#home
Electrum download

I contacted them a year ago using the contact form.
I'll try to reach them again with the details of whatever I have.
Let's see if I can get access to my wallet.

It also depends on the IP of your login access computer. If you are on a sanction list country (i.e. Iran, North Korea, Cuba, Syria etc) then they will not let you access the wallet.
