Hello fist excúseme for my english my native language is spanish

i need import my multisignature wallet (2-3) created in copay an i need open in  electrum, because i need use the founds, copay has a limit to 20 gaps and wih code im  generated a lot of wallets fot a private payment system, now i can see a funds located in a address generated by my xpubs, my wallet have a 12 words in spanish and when i introudce in electrum the balance is 0 im use the 3 seed and no funds.


when i put the xpub i can see the funds but i cant sign because generate only watch only funds.


Thanks for your help

Bueno les cuento yo tengo una billetera creada en copay es una billetera multifirma necesita dos firmas de 3 osea (2-3) estoy intentnado importarla a electrum pero no lo he podido hacer la importo y me aparece en 0 btc

pero cuando importo las claves publicas si me la deja importar pero unicamente veo los fondos claramente no puedo firmar transacciones, sucede que copay tiene por defecto el gap limit en 20 y necesito sacar unos fondos que estan metidos en una direccion muy adelante por que generamos mas de 20 por medio de un codigo externo, y son fondos que no hemos podid usar y electrum si me dejaria usarlos ya que me permite modificar los GAP limit.

Agradezco la colaboracion.

Can you find the xprv's? You'll have to try and use those if you can.

You can't use the seeds because one it bip39 and electrum doesn't use that by default so the easiest way to do this is to use the xprvs.

---

You're probably better off making a new wallet and transferring the funds to that however.

I have not tested this method... but theoretically, you could import the 3x seed mnemonics into 3 different Electrum wallets, using the "BIP39 seed" option... DO NOT set a password.

From each restored wallet in Electrum, you should be able to get the xprv by looking in the unencrypted wallet file (hence the requirement to not use a password)

(Alternatively, you could put the 3x BIP39 seeds into https://iancoleman.io/bip39/#spanish and then copy the xprv from the "Account Extended Private Key" textbox. I suggest you download the sourcecode for the website and run offline if you want to use this method. Instructions for this are at bottom of the webpage. Personally, I would recommend the Electrum method.)

Once you have the 3 xprv's, you should then be able to create a MultiSig wallet in Electrum using these 3 xprv's... (which should hopefully match the addresses in your Copay 2-of-3 MultiSig wallet.) and which should let you spend as you meet the 2-of-3 requirement.

Again, I have NOT tested this to see if it works as I don't use Copay.

Hi have the xpriv of 3 signatures but when the wallet open after I put the xpriv show balance 0 and don't show transactions

Did you get the xprv from copay or electrum?

What derivation path did you use if its electrum. If its copay, it's likely your funds are stored in a change address and I'm not sure how to deal with that in that case.

Did you also import them under the multisig option in electrum?

Are you sure that you've restored it as a multisig wallet?

Example: https://i.imgur.com/GRjVqFk.jpg

If it is a multisig address, Electrum's title bar should display "[2/3],[3/3],[2/2]" depending on the number of required signatures and cosigners.
If "standard" or "imported" it's not multisig.

Because, in my understanding, you only have one SEED and copay have the rest, you only got the the xpub of copay's SEEDs for view-only purposes  :-\

---

<Edit If you happen to have all the SEEDs>
This will happen when you choose "Use Master Key" and pasted just the xpub of the three cosigners.
What you need to do is to make Two(2) Electrum Wallets hodling each of the two seeds to be able to (2/3) sign a transaction.

It needs to be exactly 3 Cosigner and 2 Required Signature, changing the wallet's cosigner settings will generate a different set of address (I've tried it just now).

Ok... I have tested my proposed method... and it works... so here is a (very) long tutorial with pretty pictures! ;)

EDIT: Ok, follow Abussamad's advice below... and use the seed option, just remember to change the derivation path to m/44'/0'/0' for each seed!

EDIT: Nothing below here is required if you have the three 12 word seed mnemonics from Copay

---

I setup a Copay 2-of-3 MultiSig ("Shared Wallet) on my PC, Android Phone and Android Tablet. Within the shared wallet, you can go into the wallet settings and "backup" the wallet, which will show the 12 word seed mnemonic for the Shared Wallet (by default, each wallet in Copay/Bitpay has a unique seed mnemonic!):
https://talkimg.com/images/2023/11/15/zg5sD.pnghttps://talkimg.com/images/2023/11/15/zg79f.pnghttps://talkimg.com/images/2023/11/15/zgBXZ.png

Test Mnemonics:

---

---

Now, you will have to convert these seed mnemonics to xprv's, because I tried creating the Electrum Multisig from the seeds and it DOES NOT WORK! (even when selecting BIP39!!?! :-\)
https://talkimg.com/images/2023/11/15/zggt8.png

---

---

So, what you need to do is, for EACH of the 12 word seed mnemonics that you got from Copay, you need to get the xprv:

"File" -> "New\Restore" -> Create a unique easy to remember wallet name, for instance I used "C1", "C2" and "C3" -> "Standard Wallet" -> "I already have a seed" -> click "Options" -> select "BIP39 seed" -> Enter Seed, click next -> Select "legacy (p2pkh)":
https://talkimg.com/images/2023/11/15/zgic3.png

Then click next and DO NOT ENTER A PASSWORD! - This is important. If you enter a password, the wallet file will be encrypted and you will not be able to read the xprv when you open with a text editor!

Repeat for the 2nd and 3rd seed mnemonics that you have.

---

---

Now you need to find the wallet files... on Windows this will be: %AppData%\Electrum\wallets

You can press Windows+R then type %AppData%\Electrum\wallets and press enter:

Read here for other operating systems: http://docs.electrum.org/en/latest/faq.html#where-is-my-wallet-file-located

---

---

Open the wallet files you created (eg. "C1", "C2" and "C3") in a text editor. Find the "xprv" entry:
https://talkimg.com/images/2023/11/15/zgbM9.png?1https://talkimg.com/images/2023/11/15/zgpJN.pnghttps://talkimg.com/images/2023/11/15/zgDpa.png

In my test, I got the following:

---

---

If you are in a hurry, you can get the xprvs directly from Ian Coleman's Mnemonic Converter: https://iancoleman.io/bip39/

This means you don't need to import the seeds into Electrum and create the standard wallets etc.

Simply put the 12 word seed mnemonics into as the BIP39 Mnemonic:
https://talkimg.com/images/2023/11/15/zgWSo.png


Then scroll down to the "Derivation Path" section, make sure to click on BIP44, and the xprv will be the "Account Extended Private Key"
https://talkimg.com/images/2023/11/15/zge3T.png

NOTE: do NOT use the online version of this website with LIVE seeds/xprvs... you should download and run the converter OFFLINE (instructions are at the bottom of the webpage)

---

---

Now that you have the THREE xprvs, you can actually create the clone of the Copay MultiSig in Electrum:

"File" -> "New\Restore" -> call the wallet something like: "CopayMultiSig":
https://talkimg.com/images/2023/11/15/zgq9l.png


Then select "Multi-signature Wallet":
https://talkimg.com/images/2023/11/15/zglX1.png


Then set it to be [From "3" co-signers, require "2" signatures"]:
https://talkimg.com/images/2023/11/15/zgxzm.png


Now, VERY IMPORTANT... select "Use a master key", Put in the "C1" xprv and click "Next":
https://talkimg.com/images/2023/11/15/zi2cW.pnghttps://talkimg.com/images/2023/11/15/ziU0J.png


Ignore the Master Public Key and click next, then select "Enter cosigner key" when asked to "Add Cosigner (2 of 3)", Put in the "C2" xprv and click "Next":
https://talkimg.com/images/2023/11/15/ziXmC.pnghttps://talkimg.com/images/2023/11/15/zidJb.png


Then repeat the same process for "Cosigner (3 of 3)" using the "C3" key:
https://talkimg.com/images/2023/11/15/ziupv.pnghttps://talkimg.com/images/2023/11/15/ziAZH.png


This will then create the MultiSig wallet in Electrum, that will have addresses that match the addresses in Copay:

At this point, you should see your transactions and funds... and be able to spend the coins (as your Electrum wallet has all the private keys in it ;))

Restore from seed does work. Choose multisig wallet and then 2 of 3. In the seed entry step click on options and check bip39, enter the seed and make sure once you've done that it says 'bip39 checksum ok' next to the options button. If it doesn't then check the spelling and order of the words. In the next step select "legacy p2sh" and enter this derivation path (single quotes matter):


Repeat this for each seed. That's all you have to do.

@HCP the derivation path is where you went wrong. Copay uses bip44 for multisig wallets as well.

Ahhhh I was wondering about that m/45'/0 thing... dammit, I should have tested more. :P

Thanks for the update. Have modified the post to reflect this.

i get my coins back based in this method but i covert the seed to extend xpriv in bip39 tool because the xpriv from copay not work TAHANKS for all guys !

HELLO! I HAVE DONE THE SENDING OF MEANS FROM THE WALLET ELECTRUM! I HAVE BEEN HELPED THE MESSAGE THAT YOU CAN'T DO THIS DO WHEN YOU DO NOT UPDATE YOUR WALLET BEFORE VERSION 3.3.2! AND GIVE TWO LINKS TO DOWNLOAD! I have not paid attention to it.

OPERATION FOR ALL THE FUNNIES WHICH WERE IN THE ACCOUNT! 21.9667747 BTC !!!

THE OPERATION HANGED ALL DAY WITHOUT A SINGLE CONFIRMATION AND ONLY AT THE END OF THE DAY, CONFIRM AND REMOVE ALL THE MONEY FROM MY ACCOUNT! PROMPT WHAT DO I DO!?

It looks like you were scammed. If that was the case, your coins are gone. :/

Post here the links you were instructed to download for the fake update.

Did the message look like this? https://bitcointalk.org/index.php?topic=5090097.0

http://
Here is the link! uploaded through the photo exchanger! https://ibb.co/r6LXwXN

This is a known error and it's from a scammer.

Change the server you're connected to in the network tab under tools>network.

DO NOT CLICK THE LINKS.

Yelp, if I understood correctly, you did download and run the files from the fake links, right? If so, you got scammed and there is nothing else you can do.

I can not understand how then I received this notification from the electrum wallet! No single virus detected on computer! Is it still hacked by the electrum itself?

Can you release on e of your multisig addresses just to check.

The virus is in the download as that box is sent from the server. As you'll notice that's electrum.cf and not electrum.org.

The electrum software was hacked and someone sent a message through that system as its a rediculously easy vulnerability to manipulate. I really hate these cheap scams.

If you have any more bitcoin. Get a new computer before doing anything with them...

nbhgh

Tell me how to write to the moderator 'ThomasV'! I write that I can not write to him because I'm new!

Talking with ThomasV is useless. Let me explain what happened.

A hacker found an exploit on the Electrum software that made possible showing fake erros messages for users connected in specific servers hosted by the hacker. The “please update to version 3.3.2” message you saw was fake. What you downloaded from that link was a fake Electrum wallet that automatically sent all your coins to the hacker’s address.

Unfortunately, you can’t get your coins back. Bitcoin transactions are irreversible and your coins are gone. Not even ThomasV can help you. There is nothing anyone can do. Sorry.

as I understand it all the same elect site itself? !!!! since my wallet was downloaded from the official site elecrum.org !!!!!!!

But you clicked the link in that message yes, and downloaded the byte executable from it?

Things went wrong when you downloaded the “update” (which is fake) from the websites mentioned at the fake “please update” error message.

The only original website: https://electrum.org
The fake website (from your screenshot): https://electrum.CF

Yes ! exactly  !

Then you have been scammed. By both the owner of that server and your own poor judgement. It is the server and hacker alone who is really to blame for this.

I'm sorry but your coins are now gone. If that transaction is confirmed then its over... I would suggest just checking on a block explorer t u at its definitely confirmed though. Try btc.com with your address.

I just need to mention that there's a short notice on electrum.org download page stating:

And from the Important Announcement Board (https://bitcointalk.org/index.php?board=87.0) since the very first hour of the incident:
With those (together with the fact that it is an open-source project), we can assume that any incidents involving that particular hack can't be blamed to Electrum's developers.

---

You can always turn to the authorities (Police) and report the incident, same as this guy (https://bitcointalk.org/index.php?action=profile;u=74328) who had his Electrum-stored Bitcoins (and Altcoins) stolen.
The chance to retrieve your coins might be slim but it's better than chasing your tail.

and still you can tell me how to communicate with the moderator 'ThomasV'

Not sure what do you want to talk with him? Like I said: there is NOTHING he or anyone else can do to help you or recover your coins. Simple as that.

He’s also well aware of the exploit and has made some changes on the latest version of Electrum (which you didn’t had) to help preventing people from falling for this scam.

and yet they attacked me on the wallet that was downloaded from the official site of the electrum, so I don’t think that the electrum has nothing to do with it!

No one denied that fact. Like I said, it’s an exploit on the Electrum software. Electrum didn’t “attack” you. The hacker did. At the end, you did download the fake software from the fake Electrum website (electrum.cf).

Like I said, there is nothing he can do. ThomasV can’t recover your funds and I’m pretty sure he can’t take from his own pocket to pay you (if that’s what you are wondering).

If you want my suggestion, just move on. Sadly that’s all you can do.

I ALL UNDERSTAND BUT EVERYTHING WOULD LIKE TO TALK WITH ThomasV

vanya770707, you lost your coins just because you did not read warning on official Electrum site. It is clearly stated there that users should not download Electrum with no other location then official site, and you did just opposite thing.

However it is true that hackers use exploit in official Electrum to fool users and point them to fake wallet, but this is obviously something that can not be so easily resolved. This is risk every users must take over when dealing with cryptocurrency, turn you brain on and read with understanding.

If you still want to contact developer of Electrum try to send him message on his bitcointalk profile : https://bitcointalk.org/index.php?action=profile;u=3137 or maybe on Twitter : https://twitter.com/ElectrumWallet

But as you can see he is not active here more then a month, and even if he is there is no help for your problem.

Don't know if these will help:

• electrumdev@gmail.com (displayed in Github so I guess that there's no problem pasting this here) based from ThomasV's GitHub Profile (https://github.com/ecdsa).
  
• Bitcointalk Account: ThomasV (https://bitcointalk.org/index.php?action=profile;u=3137)
  
• Electrum Twitter page (https://twitter.com/ElectrumWallet).
  
• Electrum Page's registration address:
