Topic: [Solved] How to claim BTG from an Electrum wallet? - page 2. (Read 23558 times)

You don't need but it's recommended. Especially if you are going to import your private-key in a not so reliable wallet.

All wallets supporting BTG can be found in their official website.

Which one? I imagine that you are talking about the web wallet that were storing private keys/seeds? Because that one wasn't created by anyone from the BTG dev team.

Why?

Do you need to or would you advise sending out all the BTC from an address before importing it into some BTG wallet? Also, which BTG wallet do you recommend/use? The one from their official site was recently compromised (among other things wrong with BTG).


There is/was, you're just going to have to be willing to say "bye bye" to your BTC's during use.

Maybe you can do it by using Bitcoin Gold core? The problem with BTG is that there are almost no working wallet available.

At least with BCH we had Electron Cash right after its release.

Anyway to do this "cold" like with Electron Cash

Don't want to risk putting private key inside an Android phone (which are always full of exploits) or on an online computer with the main wallet

Rather create the transaction and sign it offline

Sadly, no... The simplified process as it stands requires you to be able to:

1. Disable the 2FA features of your 2FA wallet (restore -> 2FA wallet -> enter seed -> select "disable" -> DO NOT SET a wallet password)
2. Extract the 2 xprvs from your now "unencrypted" wallet file with a text editor
3. Get the "redeem scripts" for all the "3" addresses that hold coins
4. Use coinb.in to "decode" the redeem scripts and identify the "1" addresses that have been used to generate your "3" addresses
5. Use your extracted xprv's on https://iancoleman.io/bip39/ to generate "1" addresses and matching private keys
6. Match generated "1" addresses from https://iancoleman.io/bip39/ to "1" addresses from "redeem script" decode
7. Manually create a raw transaction in BTG Core wallet
8. Sign the raw transaction with private keys found at https://iancoleman.io/bip39/
9. Broadcast the signed transaction

Steps 1-6, aren't that difficult... and can be done relatively easily... a lot of point and click and copy/paste etc... Not super technical, they are just pretty time consuming.

Step 7 requires pretty indepth knowledge of how transactions are actually created and require some fairly low level Bitcoin fun... for reference: http://www.soroushjp.com/2014/12/20/bitcoin-multisig-the-hard-way-understanding-raw-multisignature-bitcoin-transactions/

Unfortunately, that article kind of glosses over the "spending" part of the process and "cheats" by using the wallet code to do it... We don't have that luxury here... as we're dealing with this at the private key level... and there aren't any BTG compatible tools

Step 8-9, aren't too difficult either...

Additionally, this process will also require that you install BTG Core wallet and download the entire BTG blockchain.

OR

You can wait until someone puts out a BTG compatible version of Electrum.

Can you explain this to someone with no much knowledge to scripts and devs ? (I have 2fa wallet)

A 2FA wallet? Excellent, that makes things a little bit easier

Like I said earlier... you cannot simply export a key from an Electrum MultiSig address (Electrum 2FA wallets are a fancy type of MultiSig)... it just doesn't work like that.

- MultiSigs are made up of several keys (2FA's are made up of 3)
- You need to get all the individual pieces (Electrum will only give you 1, by clicking "export private key"). This requires digging around in wallet files and using various tools to convert the redeem script into individual addresses and using xprvs to find the private keys for those individual addresses
- Once you have all the pieces, you can use them to manually create a "raw" transaction.
- You then sign the raw transaction using the individual pieces that you extracted and you can broadcast the message.

Hey - yes I have a 2FA wallet. I imported my private key to a new electrum wallet and now that private key is assigned a "1" address.. which doesn't display the amount of BTG I have available like my "3" address does.... since the private key is now assigned to a  "1" address does this mean that I'll be able to recover the BTG since the private key is also associated with the 3 address or does this not work?

I'm sorry if this sounds confusing - I'm really just trying to make sense of it myself. Any help is appreciated - thank you so much!

As I stated... There is no way to just "import keys"...

Until someone creates a BTG compatible version of Electrum, You need to dig down into the MultiSig... extract multiple keys... create a manual transaction, sign it... and broadcast it.

Is your wallet a 2FA wallet? or is it a MofN MultiSig?

I'm also struggling here. All my elctrum addresses start with 3 and therefore I am unable to import ANY BTC keys to BTG wallet. I have tried various different methods to no avail. Surely someone has a solution.

No, you haven't lost it... the private key hasn't be "reassigned"... When you export a private key from Electrum for a "3" address... it doesn't get your ALL the private keys required to recreate that "3" address. Your wallet should say something like "2of3" or "2of2" or something like that in the title bar... The first number is the minimum number of signatures required to sign transactions... the 2nd number is the total number of private keys used to create the wallet.

So if you have "2of3", the wallet was originally created by merging 3 keys together... but you only need any 2 of these to sign a transaction. Depending on how the wallet was actually made will determine how many private keys are actually stored in your copy of the wallet... and whether or not you need private keys from other wallets to "co-sign" your transaction.

Do you remember how you setup the wallet? what xprvs, xpubs you used? or did you create a "two factor authentication" aka "2FA" wallet?

Ok well now I'm totally confused, did I lose my BTG forever? Because --- I just imported my private key from my Mac which contained the "3" address and I imported the associated private key to my Dell PC Electrum wallet and created a new wallet through the standard set up and imported my private key.... now my private key that was on my Mac has a "1" address... but when I look up the "1" address the explorer doesn't return a result... but when I go back to view my "3" address I still see the BTG


Did I lose it forever since my new electrum wallet reassigned my private key to a "1" address?
