Topic: Extracting Bitcoin Gold from 2FA & Multisig Electrum Wallet - page 3. (Read 2932 times)

It shows the BTG as sitting there unspent when I put them in https://btgexplorer.com/


I followed the steps in this thread as such:

createrawtransaction '[{"txid": "the txid from the address holding btg on electrum", "vout": 1}]' '{"my btg address in core":  amount_of_btg_to_move_here}'

that gave me my raw hash

signrawtransaction "the_raw_hash" '[{"txid": "txid from above", "vout": 1, "scriptPubKey": "pub_key_here", "redeemScript": "redeem script from electrum", "amount": "amount_of_btg_to_move_here"}]' '["first private key to sign with"]'

Got the error it says to expect, along with a longer hash

signrawtransaction "the_longer_hash", "vout": 1, "scriptPubKey": "pub_key_here", "redeemScript": "redeem script from electrum", "amount": "amount_of_btg_to_move_here"}]' '["2nd private key to sign with"]'

it says complete and tosses out another hash.

Now I do this and have the error...

sendrawtransaction "the_final_hash"

**I'm scratching my head here**

It means some of the inputs you are attempting to use, don't exist (anymore)... so they've either already been used in a transaction... or you are using the wrong inputs.

Hmm..

so I'm trying this here:

createrawtransaction '[{"txid": "my input txid is here", "vout": 77531100}]' '{"my bitcoin gold address is here": 77450000}'

and I'm getting this:

Amount out of range (code -3)

What does that mean?



UPDATE: nevermind.. now I'm hung up at signing the with the 2nd private key.  I'm getting this message:

"error": "Script evaluated without error but finished with a false/empty top stack element"



YET ANOTHER UPDATE:

I got the signed HEX value, now when I attempt the sendrawtransaction I get the following:

Missing inputs (code -25)

You are right.
I have the core installed and sync finished today.
Need to find the time to do it, I will update here.

Thanks!

Ady.

No, it won't... because the Trezor tool is designed for claiming the BTG from your Trezor BTC wallet... NOT from other wallets.

If you need to get the BTG from your Electrum 2FA wallet, you'll need to follow the guide that they have provided here... and you'll need BTG Core installed and fully synced... or you'll need to get someone you trust that has BTG Core, give them your Electrum 2FA seed and let them do it on your behalf.

I have the same issue, f2a electrum wallet.

trezor have a new solution for this, didn't check it, I wonder if it will work for the f2a multisig

I will check it tonight and update.

* wallet new version to support this is still in beta, so I will wait few more days.

lol.

We just extracted BTG from a Segwit address for a client. It was hard to figure out at first, but relatively straight forward once we figured out our issues. The WS team member that did that job it will write it up soon so the community can benefit.



Thank you for your feedback.

We are one of the good guys, acting ethically, doing hard work, and giving away game for free. Our intent is to make a good name for ourselves and offer our services for many years in many different forms. That being said, we understand your desire to preserve the integrity of your private keys for future forks. We understand that our guarantee to delete your seed immediately after BTG retrieval and never extract any other coin without your approval is not good enough for you, and we can respect that.

We don't use Skype for security reasons, but for $100/hr (minimum 1 hour charge, ) we can have a team member jump on a Telegram, Cryptocat, Signal or something similar and work with you through to extract your BTG, telling you exactly what to type into the debug console. You will never have to reveal your seed or private keys to us. Note that you must have the latest version of Bitcoin Gold Core with the ~140GB blockchain fully sync'd.  (Also make sure you didn't download the "scam version" that was available from their Github for 1.5 days earlier this week)

DM or email us walleting.services at protonmail dot com and we can set up a time.

Sorry but that's what I think, if you can do it you could write a simpler tutorial and earn with tips, because if I can, thanks to you, recover my BTG automatically I feel I owe you something, I think everyone in Bitcoin community if they find themselves in a situation like this would think the same, the soultion so would be to write a simpler guide with screenshots.
That's because no one, even at the cost of losing money, would give their private keys. There will be more forks, it can happen something, but the private keys are personal, so it's obvious no one would agree to that, even at a price like 5% or 2%.
So if you wanna help give help following on Skype step by step and getting paid 10% or write a simpler tutorial and earn by donations. That's my piece of advice.



Can you help me step by step on Skype via Chat? I can pay you 7% of my Bitcoin Gold

Has anyone been able to extract BTG from a SegWit address?

We are currently banging our heads against this one for a client. Not sure if it is even possible right now. We keep getting an error:

Segregated witness not enabled on network (code -4)

Bitcoin Gold website claims they support Segwit, but Bitcoin Gold Core claims the network doesn't... We wonder if it's possible to mine such a transaction but not possible for the Core client to broadcast it yet...

 

If you follow the instructions above it will work for you. If you have multiple previous (deposits)  inputs to the address you are trying to unlock, the command becomes rather long, though achievable. Let me know if you need any help

We can do it for you at a special rate of 10% drop us a PM or an email and mention this post.

I don't understand the order from the instructions from the first post and the detailed 5th post, can someone clear that to me please?
And if someone can write the instructions in a simpler way would be great

Figured it out for anyone who's interested. Make sure you use the amounts of the original inputs when signing. I was using adjusted amounts to allow for fees, which was incorrect. Although it will sign correctly, the transaction cant be sent. The fees adjustment need only be taken into account when creating the transaction, not while signing it.

Excellent instructions, many thanks. Got the Tx created and signed correctly, however when I try to send transaction to network I am faced with the following error.

mandatory-script-verify-flag-failed (Signature must be zero for failed CHECK(MULTI)SIG operation

Any ideas?

Hi.
Cannot find needed multisig adresses (with funds) after regenerating my 2FA electrum (with disabled 2FA).
Can't find them after regenerating with enabled 2FA either. Am I doing something wrong?

Thank you very much for the recognition and the tip:

We felt the most ethical thing to do was give away the info on how to solve the problem while offering our service to do it for customers who don't want to go through all of that.

I made a spreadsheet to repeat the process a bit easier. As it is; it will only help with "one input" transactions, ie. not work for addresses that have received multiple transfers. Most of mine however had not. Link below in case it can help anyone (All the hashes, addresses etc. in the sheet are invalid).

Thanks guys!!
Got it working. I was using a wrong scriptPubKey and did not have the amount in my signrawtransaction statements.
Believe some of the wallets are working on making the process more user friendly, so that will probably come soon, but if you let me have an address i am happy to send a btg your way for your help.

First you need to gather all the inputs that funded the address (essentially you need to find all transactions that funded the address and were unspent when the fork happened).

Then you can open the console in Electrum (View > Show Console) and type the following command (replace TXID_HERE with the transaction ID of one of the input transactions from the previous step):

deserialize(gettransaction("TXID_HERE"))

You'll get a formatted JSON output. Under "outputs" you need to find your 2FA / Multisig address. Once you find it you'll see three fields under the address that you need to take note of:
prevout_n -> this is the vout value
scriptPubKey -> needed for signing the transaction
value -> also needed for signing the transaction to avoid triggering replay protection

You need to repeat this for every input!!!

Once you have all the values written down you need to create a raw transaction. You can do this by running the following command in Bitcoin Gold Core:

createrawtransaction '[{"txid": "INPUT_TRX_ID", "vout": VOUT_VALUE}]' '{"YOUR_BTG_ADDRESS":  AMOUNT_TO_SEND}'

Please note that you need to repeat the following for EVERY input!!

{"txid": "INPUT_TRX_ID", "vout": VOUT_VALUE}

So for example if you have 3 inputs the command would look something like this:

createrawtransaction '[{"txid": "INPUT_TRX_ID_1", "vout": VOUT_VALUE_1}, {"txid": "INPUT_TRX_ID_2", "vout": VOUT_VALUE_2}, {"txid": "INPUT_TRX_ID_3", "vout": VOUT_VALUE_3}]' '{"YOUR_BTG_ADDRESS":  AMOUNT_TO_SEND}'

Also note that AMOUNT_TO_SEND should be the sum of all "value" fields MINUS the transaction fee you wish to pay! (Make sure the amount is in BTC / BTG and NOT in mBTC / mBTG or anything similar).

After you run this command you should get a raw transaction hash. Next you need to sign it. You will do this by running the following command:

signrawtransaction "RAW_TRANSACTION_HASH" '[{"txid": "INPUT_TRX_ID", "vout": VOUT_VALUE, "scriptPubKey": "INPUT_SCRIPT_PUB_KEY", "redeemScript": "MULTISIG_ADDRESS_REDEEM_SCRIPT", "amount": "INPUT_VALUE_FIELD"}]' '["FIRST_PRIVATE_KEY_FOR_SIGNING"]'

Please note that you should again repeat the input part for every input like you did with "createrawtransaction" except that this time you need to also provide "redeemScript", "scriptPubKey" and "amount" fields for each input!!

Once you run this command you should see the HEX hash of the signed transaction and an error saying something like "The current operation isn't possible with the current stack size!". This error is normal and it's just saying we need to sign the transaction with another private key before we can spend the inputs.

To sign it for the second time run the same command again, but replace the RAW_TRANSACTION_HASH with the new, signed transaction hash (you can find it above the error) and replace FIRST_PRIVATE_KEY_FOR_SIGNING with the second private key. Once you run the command you should get the signed transaction hash. You can then run the following command to broadcast it to the network:

sendrawtransaction "SIGNED_TRX_HASH"
