Can you please confirm the following address is correct, and definitely for receiving bitcoin:

1J7sNfSwSa4d4Fc5sd9Fgc5SVUizYH3hbV

Can you also confirm you are happy for me to pay an appropriate fee at the time of broadcast? At the moment, this will be around 14,000 sats ($5), which will give your transaction a fee rate of 41 sats/vbyte. This may change over the coming hours and days, but if it goes significantly higher I'm happy to wait until average fees come back down again.


Thank you o_e_l_e_o


I confirm you this adress it's the good adress i'ts from my account coinbase I checked once again.

About the fee no problem, go aheah.  I hope this history will finish soon... lot of years unhappy because I dont know how its works this bitcoin


thanks again

can also someone explain me why I have, bitcoin and bitcoin cash ?
It's called a Bitcoin Fork. I wrote a topic about it years ago, although the values are much lower by now, and most Forkcoins are worthless. But you'll own a few dollars worth of Forkcoins too. Chances are it's going to a be lot of work to recover them from your multisig, so if you don't move them, just keep your multisig in case it becomes worth more in 10 years (which I don't expect to be very likely).

thank you for the information, I went to your topic but it's hard to me to good understand.

I think it's o_e_l_e_o who will take cares in 10 years about the multisig Smiley hahah



I've checked OP's address, and the equivalent BCash address contains around $5 worth of BCash. I've not bothered to check any other forks.

Langostas - I will PM you with my ProtonMail address, which you can use to send me your keys and password if you are happy to accept the risk of doing so. You can also send some of the information via ProtonMail and some of the information via forum PM to keep it separate, if you prefer. I'll take a look at them when I get chance over the weekend and confirm your receiving address before I send you your coins.



Its a good idea I will put half information by PM and other half by Protonmail.

Thank you o_e_l_e_o  and have a good weekend at the same time.

OP has PMed me his three xpubs, which I have entered in to the tool locally and discovered an address containing coins which fits exactly with the story he has given in his first post.

The next steps will be for him to decide. Either we can help him try to set up the tool locally (preferred option!), or if that fails and if OP chooses then I would be willing for him to send me his seeds and password and I can sign and broadcast a transaction sending the coins from this address to another address of his choosing. Obviously any sensitive data being sent will need to be encrypted first, which will pose another challenge.

I'm posting this here in the interests of transparency.

Hello again o_e_l_e_o

I dont have any word to say thanks to you!!!

I dont have a very good level in computer.... I preferred the second option, but I undestand that means I need to have a lot a lot of confiance in you. and to be honest, from few years ago im very sad about this situation, because I havce some money but I cant recover it!

for give you one adress, like my normal adresss in Coinbase to receive any bitcoin is good ? its starting by number 1 if I remember good.

So... thank you very much again to keep on for me, If I understand I  need to go to protonmail ( so i think i will put this name in google an I need to create a new account)
It's protonmail.com , which nowadays forwards you to proton.me . You can create a free account on https://proton.me/mail/pricing .

After recovery, you'll need a secure new wallet to send your Bitcoin to. Have you thought about that yet?


One minute ago I did my new account in proton.me/mail/pricing thank you

So... for the wallet, I putted here few messages ago my adress in Coinbase, when I go to "receive bitcoin" i see a QR code with the number of my wallet and I saw this information ... "only to receive bitcoin" so no other "netcoins I think"

can also someone explain me why I have, bitcoin and bitcoin cash ?


thank you, Im waiting for your instructions.

It seems to be that using PGP here is going to be too complicated.

Given that, I would opt for Loyce's suggestion of using ProtonMail for its end-to-end encryption. You can make an account for free, and I will supply you with my email address to send the keys to.

If you don't want to trust me then I can try to talk you through setting up and running this tool locally, but you've already said you would not feel comfortable installing and using Linux.

Hello o_e_l_e_o 


What I need to do ?

Really LInux and all that, its not posible for me... and when I realised how much hours I spent already while all this time from few years ago to try to recover this found, Im thinking thats better for me to go handworking the same amount of hours and I will keep the same money that I have on the multisig coinbase wallet, this coin "bitcoin" I dont like at all.

So... thank you very much again to keep on for me, If I understand I  need to go to protonmail ( so i think i will put this name in google an I need to create a new account)

DO NOT do that! If you post your wallet data anywhere in public, your funds will most likely get stolen.

User o_e_l_e_o offered to help you. If you want his help, and if the amount is low enough for you to risk it and trust him, you should send him a PM. Or use a more secure method of communication, like Protonmail (this adds encryption without requiring technical knowledge).

Good morning people!

I'm here!

I dont use my computer very often, Im a hand worker so im not very good with technologies Smiley

The situation is the same as I told here, I d'ont know how can I recover this founds... and for my life hapynnes its not very good for me to know  that I have some euros and Im not able to take it for me so sometimes I prefer to forget... is like that im doing from few years now.... im not proud of this situation...

I understud that if I give to you all my password (i have all the information) you will send me back all  but all people in this forum will able to take the bitcoin... and you know im  a fair person but sometimes did not work for me to be a fair person, so what can we do ? for your information, I only know how to put on a computer and how put off, I dont have facebook or something like that.

Also, im not english spoken so... This is my english and when I try to read some english on the net to find some informations its not easy for me...


Thank you a lot to asking for the situation!!!  Im open to find a solution of course... this is the only "net coin" I have in internet and the last time I bouth something that I dont know how is working really...

Kiss family!!

That's a fake sense of security. I realized the same when offering my Fork claiming service: if either one of the parties moves the funds, it's impossible for the other party to prove anything. So it really comes down to trust.

Yes, and the blowback if something goes wrong could be big.
Even if it's nobody's 'fault'
Nobody thinks you are going to cut and run over such a small amount, but I would think it would be better if one of us sooner or later puts up a webpage with that tool and let people do it themselves.

I would prefer to use PGP encryption since I can decrypt the message on my airgapped device.
Good point, that is more secure.

Yes, I could send the coins to that address.

If you do this, will you post a full HOWTO? It's ridiculous Coinbase killed this service, but it would be nice for future reference, even many years from now.
Certainly, but it's really as simple as cloning the repo at https://github.com/dlajarretie/multisig-tool, installing the necessary dependencies, and then following the instructions given. You can check the changes that fork has made compared to the Coinbase master, and see all it does is replace the defunct API and nothing malicious.

I've used this for seed phrases for my Fork claiming service:
I can do this if OP is happy with this, but I would prefer to use PGP encryption since I can decrypt the message on my airgapped device. The hot wallet which runs on the internet connected device I would use for this has never been hacked, but obviously the risk still exists.

Good advice, and this is why I moved the conversation back here after OP PMed me - so everything is in the open and to minimize any risk of scam accusations from either side.

Hey OP. I hope you will get your bitcoin "back" ASAP and this thread make me glad to see people come along and trying to help out. 🙏
But I just wanted to tell you that you should be aware of scammers/imposters here. I am glad to see people trying to help you and this people only want to help you, but be careful for people trying to be them in PM or Telegram.

I mean for example:  o_e_l_e_o would for sure not scam you and he/she only want's to help you, but be careful maybe someone trying to pretend to be o_e_l_e_o for later steal your funds.

Don't send private keys from a standard email that doesn't encrypt messages.
The easiest way to send private keys (or seed words, depending on your wallet) is if you create a Protonmail account.
~
This way, the email has end-to-end encryption and should be secure. There's of course always the risk of your (or my) computer being compromised.
Alternatively, you can send half of each private key to my Protonmail email, and the other half by Bitcointalk PM. This way the parts don't end up on the same email account.
I've edited out my own email address, obviously both parties need to use Protonmail for the email to be encrypted.

I dont know how to put linux on my computer...
I'm afraid I rarely use Windows so I don't know how you would get this tool running on Windows. You could perhaps try running Windows System for Linux. Alternatively, run a VM or grab an old laptop or something you can install Linux on.

It should definitely work on Windows System for Linux, all you have to do is download a Linux distro from the Store (or whatever it's called now) like Ubuntu or something and it will install itself, then you can open a terminal and start working.

On Windows 10 this feature actually has to be enabled manually, from Apps and Features, but Windows 11 should have it already enabled.

There are some posibilities about me for that?
If you simply want to check how much bitcoin is in your wallet, then you can PM me your xpubs and I can look up the relevant addresses for you using the tool on my end. As long as you don't send any of the seeds or passwords, then there is no chance of me being able to steal your coins and the only risk is in revealing to me how much bitcoin you own.

Hey OP, I've helped a couple of users in the past in the exact same situation as you. The issue is that the Coinbase recovery tool uses a now-defunct API, so it cannot access the balance on your addresses and then won't progress to letting you try to sign transactions.

There are a couple of options available to you. The most straight forward one is here: https://github.com/dlajarretie/multisig-tool
This is a direct fork of the Coinbase tool with the defunct API replaced with a working one.
Here's a user who successfully used this tool: https://bitcointalksearch.org/topic/m.61722006

If you are struggling to get this tool to run, then this thread might be of help to you: https://bitcointalksearch.org/topic/m.61907765




Thank you for your help!

I saw this message from you in the post you sent me,





Have you at least managed to identify the addresses and balances you are trying to gain access to here? You mentioned to me in your PMs that you are not sure how much bitcoin is stored in this vault.

Since we are struggling to get this to work for you, if you like you could send me your three xpubs (not private keys) and I could at least look up the addresses and balance for you. The only thing you lose by doing so is privacy by account of me knowing the addresses - there is no way for me to steal your coins from only knowing your xpubs. At least then we would know if you are wasting all this time trying to recover a very small amount of money. If you like I can provide you with my PGP key so you can encrypt any communication.

And moving forward, since we can't seem to get this tool working for you, then we could instead try going down the path of manually extracting the necessary xprv from your two keys and then recreating the multi-sig wallet in Electrum.






There are some posibilities about me for that?   Im agree if a need to share with you my xpub, I have only this 10 euros, (now 800) in the bitcoin and Im not a advanced user only I would like to close this chapitre for me... because Im not relax, I have also the final adresse where there are the bitcoin

Please check the video I provided above that is how I withdraw funds out from the vault.
That's coinbase vault, not coinbase multisig vault.

Coinbase vault (which is used by you) is a custodial service and coinbase has full control over the fund. There is no real co-signer in coinbase vault. When you approve the withdrawal through your email address, you only tell coinbase that the withdrawal request has been made by the real owner and it's not that you are the co-singer.

Coinbase multi-sig vault (which is no longer supported and we are talking about that in this thread) was a 2 of 3 multi-signature wallet in which the user had access to two of the keys and had full control over the fund.


From Coinbase help:

Quote from: help.coinbase.com
Note that the multisig vault is different from the regular Coinbase vault, where we handle security on your behalf so you don't have to. If you don't want to maintain your own private keys, you can use the regular vault

Are you saying you have fund in coinbase multi-sig vault and you are able to withdraw your fund from that just with entering the 2FA code and email verification? How is that possible? As already said, they no longer supports multi-sig vault.
I feel you are confusing coinbase mutli-signature wallet with their custodial wallet.
No there is no email verification but only an approval link but it asks for 2FA, I'm using their vault and I usually use it to save a few sat before it always requires approval in my Coinbase account I can approve the withdrawal from the vault but it is still pending and it needs a 2nd approval by a co-signer/secondary email I receive an email from Coinbase(as a secondary email) and the email asks for my secondary approval by clicking the approve button the vault funds will be out within 24hours and will transfer to the main wallet.

Please check the video I provided above that is how I withdraw funds out from the vault.

@OP I don't think it would ask for a password because mine only asks for a 2FA code when withdrawing after entering the 2FA it will ask if you gonna approve the transaction or not and then the 2nd email will receive a link to approve the transaction.

Coinbase multisig vault is 2 of 3 multi-signature wallet.

One of the keys is owned only by the user. One of them is stored by coinbase and the user has no access to that. One of the keys (which is encrypted) is owned by both coinbase and user.
If you own two of the keys, you must be able to spend your fund without relying on Coinbase and without any need to 2FA or email verification.

It's weird I didn't receive any update about the vault and they never gave me any keys when I set up my vault. My vault was created in 2015 with 2FA and a secondary email they didn't send me any keys for recovery only the primary and secondary email is my backup to recover my vault.
This is weird and now they do have vault recovery on Github that asks for Coinbase, shared, and user xpub keys.

@OP I don't think it would ask for a password because mine only asks for a 2FA code when withdrawing after entering the 2FA it will ask if you gonna approve the transaction or not and then the 2nd email will receive a link to approve the transaction.

Or check this video below how to withdraw from the vault

Try this NO IDEA IF IT WORKS OR NOT:
Go to https://github.com/pilsnerbeer/multisig-tool-fixed and under code download the zip file
Unzip the file to it's own folder by default by default it should put it in a folder called multisig-tool-fixed-master
In there there is a file index.html

If you do not have the chrome browser installed, get it from https://google.com/chrome

Once installed run it with the --allow-access-from-files parmamter and the index.html file

- An encrypted key which is owned by both coinbase and the user.
Which I supposed they can decrypt? Can't they? What is the point of an encrypted key in the first place if the user cannot decrypt it?
Right. OP has the encryption password and he/she should be able to decrypt the shared key, but the question is how the key should be decrypted, what's the encryption algorithm and what tool should be used for that.

Also, I am not even sure if the user share OP is talking about is a master private key or a seed phrase.

I have never also used Coinbase multi sig vault, through search I found out that you need to actual have some extended private key and if you have that then you can follow this guide to restore it in electrum https://bitcointalksearch.org/topic/m.20875786
The guide provided by Abdussamad in that thread won't help OP.
OP should recover a 2 of 3 multi-signature wallet. That thread is about recovering a 2 of 2 multi-signature wallet and is not related to OP's issue.


The weird thing is there is no announcement from Coinbase that they are going to terminate Vault Wallet and honestly creating a Vault Wallet does not generate a private key it requires only 2FA and another email as co-signer.

To spend them, install Electrum on an air-gapped device and re-create the same wallet but use xpriv.
OP has now two of the keys, but the the problem is that the one that is shared with coinbase is encrypted and there is no way to import that to electrum.

In coinbase multi-sig wallet, there are 3 keys and they are as follows.

- An unencrypted key which is owned by the user and coinbase has no access to that.
- An unencrypted key which is owned by coinbase and the user has no access to that.
- An encrypted key which is owned by both coinbase and the user.

Of course I have all the information neccesary, like the 3 xpub, encripted share, user share and my wallet password i have all the information I printed on 2016 from my wallet when I created it.
If the wallet is 2-of-3 multi-sig, and you do own two master private keys and three master public keys, then you have all the permission needed to spend coins.

Here's what I'd do if I were you:
- Install Electrum on an Internet connected device. It'd be advisable to use Electrum with proxy (i.e. Tor), unless you run your own full node and can connect there. Otherwise, Electrum servers can link your coins, and your privacy will be invaded. (Which has already happened as you used Coinbase, but anyway)
- Create new wallet -> "Multi-signature wallet" -> Enter 2-of-3 -> Enter all your xpub keys.
- Now the watch-only wallet will be initiated. Check if you can see your coins there. You can click the "Coins" tab to view the UTXOs.
- If you do see them, then great, the coins are there. To spend them, install Electrum on an air-gapped device and re-create the same wallet but use xpriv. You can create a transaction from the Internet connected device which can be signed by the air-gapped.

Obviously verify the signatures of Electrum binaries.

The vault tool from Coinbase no longer works:
https://bitcointalksearch.org/topic/--5316286

But if you read to the bottom: https://bitcointalksearch.org/topic/--5316286

Someone did make a working version at least as of 6 moths ago or so.
I can't comment on the safety of it or if it still works but it did back then.

Once you run the tool if it does work move your coins ASAP.

Hello Dave!!

Thank you very much for your reply, I saw this but I have no idea how its working...










The usage is 1:1 same as with the old tool. For complete instructions, visit https://github.com/coinbase/multisig-tool/blob/master/README.md

In short:

download & run the project with npm install and make run (also you will need python3 to be able to run local server)
input your xpubs in step 1, then (optionally) go offline and input the rest for step 2. NOTE: For destination address, use P2SH address (starting with "3"). Native SegWit (bech32) addresses (starting with bc1) reportedly do not work.
raw transaction will be generated. It will send 100% of your funds (minus the fee) to the destination address. You can use https://coinb.in/#verify to verify that it's looking good, mainly if the destination address is matching.
broadcast raw transaction using any bitcoin client (for example, run broadcast("....") in Electrum console)
you are done!




what is npm install? python3 Huh?  run local server I dont understand??? where is the link to download the project? I'm not very good with computers and internet so all this information its new for me  Huh Grin


Thanks again, maybe we found a solution for me !!!!!! Cheesy

It seems you got an email from a scammer.
Are you sure we talking about Coinbase?
Another thing is why the email from Coinbase said you can only access the vault funds if you have these two keys?

The weird thing is there is no announcement from Coinbase that they are going to terminate Vault Wallet and honestly creating a Vault Wallet does not generate a private key it requires only 2FA and another email as co-signer.


Hello, thank you for your answer Smiley


A scammer is someone who try to stole you? I dont think so, because this was the answer after I putted a message in "Contact us" by coinbase exchange.




I dont really understud the email from coinbase... the answer for me was no really clair.


at the moment (2018) i dont see all the emails from coinbase stopping vault multisig, but I found one email, you will see, they informe me... Sad





Dear Valentin,

Following up on our previous message and blog post, we will be ending support for existing multisig vaults on Coinbase on April 19, 2018. Please remove all funds stored in your multisig vault prior to April 19, 2018.

Because this product is user-controlled, you can move funds with the two keys in your control but you will not be able to access the third key that Coinbase holds after this period. Please ensure that you have access to both keys.

After April 19, 2018, access to the multisig address associated with your vault will not be available on Coinbase.

If you have any issues, please see the FAQ at the bottom of this message.

Kind regards,

The Coinbase Team



FAQ


How do I access my multisig vault?
- Log in to your Coinbase account at www.coinbase.com. You cannot access your multisig vault using the mobile app.

- Navigate to the “Accounts” tab from the top of the screen.

- Select your multisig vault from your list of accounts.

- Press the “Withdraw” button on your multisig vault.

- Select one of your other non-multisig Bitcoin accounts to transfer your funds to, enter in the amount to transfer, and any two factor authentication codes if needed. Then press the “Continue” button.

- On the next screen, enter your vault password into the password field, then press the “Approve” button.

- Once approved, your withdrawal will enter the 48-hour waiting period before the funds are transferred. There is no way to bypass this waiting period.


What if I don’t know my vault password?
If you don’t know your vault password, you can instead copy/paste the user seed into the password field. This will allow you to approve your withdrawal. The user seed was provided to you when you created your multisig vault.


Where do I find my vault password or user seed?
Your vault password is the phrase you chose when you created your multisig vault. The user seed is a string of numbers/letters that was provided to you during the creation of your multisig vault. You should have stored or saved both of these pieces of information when you created your vault.


What if I forgot/lost my vault password or user seed?
Unfortunately, Coinbase cannot provide or recover your vault password or user seed to your multisig vault. This has always been the case for multisig vaults. The multisig vault specifically puts you in control of your own security, and Coinbase does not have access to your vault credentials.

Because the vault cannot be accessed without these credentials, if you have forgotten/lost BOTH the vault password AND the user seed, your vault funds will be inaccessible. We apologize that there is nothing further we can do to help in that case.


What if I use a group multisig vault?
If your multisig vault is a group vault, it requires multiple approvals from different people for each withdrawal. Once you initiate your withdrawal, you should contact the other people who are approvers on your vault and make sure they log in to Coinbase to approve the withdrawal.

To see a list of the people who are approvers on your multisig group vault, press the “...” button next to your vault and select “Vault Details.”


What will happen when Coinbase removes the multisig vault from my account list?
Once Coinbase removes multisig vaults from the account list, it will no longer be possible to access funds using the Coinbase interface. However, this open-source multisig tool will remain available and you can use that to withdraw your funds:

https://coinbase.github.io/multisig-tool/

Please note that the open-source multisig tool does not support group vaults.

If you have any additional questions, please reply directly to this message and we will be happy to help.









the problem the open-souce multisig tool is not working, so.... I dont know what to do.... I was silly to put the btc on a multisig, I'm not a PRO I dont know for what I did this....



but I would like to say once again, I have all my passwords... seeds... all... only I need the way to put then in a normal wallet.


I apreciate your help

What I guess is you receive an email from a scammer and the scammer might be asking for your backup keys and password.
If they ask then don't send any keys because Coinbae never asks for any sensitive data(like private keys and password).

I see on my coinbase account that I have around 800€ but no idea how can I put out to my bankaccount.
If you "see" your funds: are you talking about the wallet, or Coinbase the exchange? If it's Coinbase, you can sell your funds. If it's "the wallet", than I guess you have access already and can send your funds to an exchange to sell it.

Probably might be seeing the balance from an explorer by checking is address there, I doubt he has access already because he is asking of recovering the wallet

Suggestion: sell some, but never sell everything. You have 8000% profit now, what if it goes up a lot more?


https://ibb.co/0FpsQG6

when I'm going in on coinbase, the exchange, I dont know if you can notive in my picture (first time I putted a picture on a forum) I see like my "account" is on 800€ but its not avaible to do some sell...

I already contacted coinbase exchange but no had any more reply from help.coinbase. Sad((((( it's for that I understud like Im alone for doing all that and im not really someone who are working on the sillicon valley with a lot a of competences Smiley

Thanks.

Hello Valentin,

In 2018, Coinbase ended its offering of the Multisig Vault service. Coinbase provided all customers using that service with repeated written notice of this termination of service. Customers were directed to remove all their funds before Coinbase permanently shut down Multisig Vault service. At all times, customers in possession of their two multisig vault keys were and are able to remove their BTC. Customers who are no longer in possession of their two keys are not able to access and remove their funds.

Unless you have access to your two keys, there is no access to the funds you left in the multisig vault.

Thanks,
Coinbase Support



in the email they told like i can take my founds i have all my seeds and paswords... I have all but only I dont know how, using the coinbase exchange its not posible they stop  working with this product..

I think he talks about the vault wallet from Coinbase and actually, there is no tool that you can use to recover the Coinbase vault.

If your Coinbase account was created in 2016 then to withdraw your funds from the vault is by providing your 2nd email(co-signer).
Based on my experience when I withdraw my funds from the Vault Coinbase emails me on my two emails with a link "Approve withdrawal" You should click approve withdrawal if you want to take your BTC out of the vault.

If you can access your Coinbase account you should be able to withdraw funds from the vault but the problem is if you still have control of your 2nd email?

Hello hello,

Im Val, and I have some troubles from few years ago...

On 2016 I bouth 10 euros bitcoin, and I putted then in a multisig coinbase wallet, now I see on my coinbase account that I have around 800€ but no idea how can I put out to my bankaccount.

I saw a lot of messages here, like the tool recovery is not working and its true, it's not working and for me never had worked.

I tried electrum.... and some other programs but Im not very good on the net, and also Im not a englishspoken, today I decided to write you a message otherwise I will forget this money because a lot of time wasted already for nothing,

Of course I have all the information neccesary, like the 3 xpub, encripted share, user share and my wallet password i have all the information I printed on 2016 from my wallet when I created it.


Can someone else, give some information?  I dont know really a lot of information.


Thank you very much!!!!
