What type of address are you trying to sign with? I'm guessing that it is a multisig or 2FA wallet that you are attempting to sign with?

In that case, I don't think it is possible to sign a message with a multisig address. See https://bitcointalk.org/index.php?topic=1576803.5

I would like to do same like here..

my wallet is with 2fa

Unfortunately, Electrum 2FA wallets generate MultiSig address. As you cannot sign messages using MultiSig addresses you will not be able to do this. You can only use "standard" Pay-to-PubKey-Hash (P2PKH) addresses to sign messages... these addresses all start with "1"

sorry, I am noob.
I do not see any addresses which start with "1" in my wallet. Looks like I can not apply for https://www.stellar.org/blog/bitcoin-claim-lumens-2/

[HCP]

Apparently you can with a MultiSig address...

1. Authenticate with Facebook.
2. Enter your Stellar account ID.
3. Enter your Bitcoin address. For P2SH (multisig) addresses, you will be asked for a redeem script.
4. Sign a displayed message. For P2PKH (normal bitcoin address) only one signature is required. For P2SH (multisig) addresses you need to provide as many signatures as required to release the funds from a P2SH address.
5. If signatures are correct, lumens will be sent to your Stellar account.

Not quite sure exactly what sort of redeem script they require, or how you go about generating it... and getting 2 sigs using a 2FA wallet would require you to ask TrustedCoin for help or to restore your 2FA wallet using your seed which apparently puts 2 of the 3 keys on your computer... see: http://docs.electrum.org/en/latest/2fa.html

Pay attention to the note at the bottom tho:

Note: The “restore” option should be used only if you no longer want to use TrustedCoin, or if there is a problem with the service. Once you have restored your wallet in this way, two of three factors are on your machine, negating the special protection of this type of wallet.

If you want to sign using a Bitcoin address, you need the P2PKH address.

Go to File>New/Restore>Select Standard wallet> Create a new seed. Copy the seed down and remember it. You will then have generated a normal P2PKH wallet. Unfortunately, you cannot claim that giveaway since the snapshot has been taken already.

can I do it with bitcoins on my wallet? or I can lose them during this procedure

[HCP]

It's too late... they took the snapshot like 2 days ago... if your coins were not in the address when they took the snapshot... putting them there now will achieve nothing.

Unless you can figure out how to get your redeemscript(s) for the address(es) that contained your coins when the snapshot was taken AND how to get 2-of-3 sigs for those address(es)... then you will not be able to participate in the Lumens giveaway...

EDIT: Well... it seems you can simply recreate the redeem script within Electrum itself... Thanks to this post by Abdussamad: https://bitcointalk.org/index.php?topic=1990373.msg19822954#msg19822954

You can use the console within Electrum (or use the "New MultiSig Address" feature on Coinb.in) to generate the redeem script for your Electrum 2FA address... NOTE: you must ensure that you put the public keys in "lexicographic order"... as Electrum does not necessarily show them in the correct order! Lexicographic effectively means "numerical and alphabetical" order... for instance, a key that starts 02e6 comes BEFORE 02e7 and 0334. Order in hex is: 0 1 2 3 4 5 6 7 8 9 a b c d e f

If you don't get the keys in the right order, then the generated address and redeemScript will be incorrect!

Code:

>> createmultisig(2, ["02e61b5030d21d2a520e19a22ce7180310d79c48f377a586d926fe38ff6f7df534","02e796ea85ac10b9c12a9b812982844b4b31c71c8a754b74c5213f9b0f7b6f456d","03341434abf31791a735e02ccc2cad2c1ddda85686545639b6f039c2317cd89125"])
{
    "address": "3KcuqgVsoxCZPv7ZuGSY7LHFyaxbib4dLs", 
    "redeemScript": "522102e61b5030d21d2a520e19a22ce7180310d79c48f377a586d926fe38ff6f7df5342102e796ea85ac10b9c12a9b812982844b4b31c71c8a754b74c5213f9b0f7b6f456d2103341434abf31791a735e02ccc2cad2c1ddda85686545639b6f039c2317cd8912553ae"
}

Now, the hard part will be signing the message required by the Lumens giveaway using 2 of the 3 private keys...

[heropzy]

hi guys,
I met the same problem, and asked to sign 2 of 3 address form P2SH address.
If I give up the electrum 2FA wallet and restore, could I sign after that?

[dedocry]

You are claiming P2SH address. Please sign the message above using any 2 of the following addresses:

I tried to signing  on of them, but I have received "the address is not in your wallet"..that next?

how can I signing new addresses?

[Muhammed Zakir]

hi guys,

No, you can't sign messages with multisig address (starting with '3'). There is a way to prove ownership of that address. For that, see post above yours.

  -snip-

Hi HCP,

Could you please confirm if I restore my 2FA wallet using seed, could I sign the 2 of 3 '1' start address and claim the XLM?
Thanks

@heropzy: Posting once is enough. And restoring 2FA wallet using seed will still create multisig address, not P2PKH address (starting with '1'). So, no! Please read post above yours before asking questions again!

Hi Zakir,

Was the way to prove ownership of that address as below?

So that if I restore the 2FA electrum wallet, I would get 2 of 3 keys of '1' address?

No! Restoring 2FA wallet would put two xprv keys* in your computer. To know P2PKH addresses (starting with '1') needed to sign message with and to get their private keys, see https://bitcointalk.org/index.php?topic=1989262.msg19845248#msg19845248.

By the way, please don't post same thing in many threads. Stick to one and post in another only if you didn't get any reply. You need to at least wait a few hours, sometime for even a day.

* 2-of-3 multisig addresses are created on 2FA wallet. Those two keys are what needed to sign a transaction when sending bitcoins.

Noted with thanks, Zakir.

Ok... I *think* I might have this all figured out... I can't test it, as I don't have any coins in a MultiSig address, so the Lumens claim form won't let me get to the message signing part. So, this method is 100% UNTESTED!

NOTE: Please consider the risks of potentially "exposing" your xprv's... you should run offline copies of all websites, and run them using non-networked Virtual Machines or air gapped PCs or "Live" distro's if possible. I will not be held accountable for any loss of coins should you choose to follow these instructions!

HCP's extremely complicated 12 Step Method for claiming Lumens from an Electrum 2FA MultiSig Address

Step 1. Before you start, create offline versions of:
https://coinb.in/#verify
https://iancoleman.github.io/bip39/

Step 2. Retrieve your redeem script. This can be achieved following the previous instructions here: https://bitcointalk.org/index.php?topic=1989369.msg19830190#msg19830190

Step 3. Once you have your redeem script, you can identify the P2PKH (aka "1") addresses that you need to sign your message with by using the following site: https://coinb.in/#verify  Again, you should really download an offline copy (link provided at the bottom of the website!)


Step 4. "Restore" your Electrum 2FA wallet ("File" -> "New/Restore" -> Call it "restored2FA" and click "Next" -> "Wallet with two-factor authentication" -> "I already have a seed" -> [Enter your seed] and click "Next" -> "Disable" -> Don't enter a password and click "Next" WARNING: This creates an unencrypted wallet that has your xprv in PLAINTEXT hence the warnings about doing this OFFLINE!!!

Step 5. Find your "restored2FA" wallet file (%appdata%\Electrum\wallets) and open it in the Text editor of your choice. You should find sections labelled "x1/" and "x2/" that contain your two xprv "rootKeys":


Step 6. Using your offline copy of https://iancoleman.github.io/bip39/  - Put the "x1/" xprv into the "BIP32 Root Key" section (leave mnemonic empty). Select "BIP32" under Derivation Path. Set "Client" to "Custom Derivation" and set the Derivation Path to "m/0":

NOTE: if your original "3" address was a "Change" address (check the address tab in Electrum), you need to use "m/1"



Step 7. Hunt through the list of generated addresses until you find one that matches one of the "1" addresses generated in Step 3 (The PubKey should also match one of the PubKeys used to generate your redeem script in Step 2):


Congratulations, you now have the private key for one of your 3 "MultiSig" addresses.

Step 8. Repeat Steps 6 and 7 using the "x2/" xprv... you now have 2 of your 3 private keys!

Step 9. Import those private keys into a "standard" Electrum wallet ("File" -> "New/Restore" -> "Standard Wallet" -> "Use public or private keys" -> Copy/Paste the private keys and click "Next"... and use them to sign the Stellar/Lumens verification message as required.

Step 10. Make sure you have deleted the unencrypted "restored2FA" wallet. or alternatively, move all your coins out of your 2FA wallet as you should probably consider it compromised.

Step 11. Enjoy your Lumens

(Optional) Step 12. Consider a tip if this actually works!


As an alternative to using the https://iancoleman.github.io/bip39/ website, you can just create a new Electrum wallet, and import the xprv: "File" -> "New/Restore" -> "Standard Wallet" -> "Use public or private keys" -> Copy/Paste the "x1/" xprv and click "Next". Your wallet should generate the required address. Check the "address" tab, you may need to select "Wallet" -> "Addresses" if it is not visible:


You can then right click this and "Sign/Verify Message"... you will need to then "restore" another wallet using the "x2/" xpriv, and sign the message using the 2nd required address.

Personally, I think I prefer the BIP39 website method as it creates only one wallet that has both the private keys for signing the message.

Step 7. Hunt through the list of generated addresses until you find one that matches one of the "1" addresses generated in Step 3:

Congratulations, you now have the private key for one of your 3 "MultiSig" addresses.

  -snip-

There is only "one" multisig address address and m number of addresses(public key, actually) used to create a multisig address. The private key you get by follow the steps above is private key corresponding to one of the addresses used to create your multisig address.

I didn't understand what you mean by this(bolded part). Can you please explain?

[dedocry]

I did till step 6. But on step 7 cann't find  one that matches one of the "1" addresses generated in Step 3...
