Topic: Electrum not sign transaction ? (Read 868 times)

Regarding pooya87's screenshot above, (Tools > Load transaction > From text) I'm curious to see what this looks like, and how long it is.

On electrum's website (https://electrum.readthedocs.io/en/latest/coldstorage.html), they don't mention the text option; they just say "" which assumes nothing nasty is running on the 'cold' machine looking for an exit hole, which doesn't sound very pleasant.

Thanks!

Hi pooya87, thank for your help.
After some attempts, I realized where I was wrong
In the online PC, when I created the wallet, I choosed the Watch Bitcoin addresses instead of the Standard Wallet.
Here's the mistake 
Thanks again for your help
Hi

it seems like you have done everything correctly. and i can't think of anything else. it is either electrum that can not recognize the transaction or there is a bug.
maybe someone else has something to add.

meanwhile try copying the transaction itself instead of using a .txn file to transfer.
in the preview window click the Copy button and paste it in a simple text file and then import that string (the transaction hex) into your cold storage from Tools > Load transaction > from text



you can even open the .txn file with a text editor to see its content, maybe a JSON key is true while it should be false and is causing this!

Hi pooya87, thank-you for your answer

Yes, both wallets (online and offline) are eguale version: 2.83. The OS is Lubuntu 16.04.

I exported from the wallet offline the public keys, not private keys.
In the wallet online I've imported the public keys after. (As the guide http://docs.electrum.org/en/latest/coldstorage.html)

I believe yes, I think the procedure is correct But something is wrong

Thank-you very much for your help.

are both wallets (online and offline) the same version? tell us which version is it.
also is your wallet created from seed or did you import the private keys? make sure you are spending "coins" that belong to the private keys that the offline wallet has.
because the reason why that button is not enabled is either because electrum doesn't have the private keys or it recognize the unsigned tx format.

Hi guys,

I tried to use Electrum with the actual latest version (2.8.3) with Cold storage but I encountred problems. Is there someone of you that could help me to create an outbound transaction?
I can't sign the transactions in the offline pc and threfore spend my coin.
Now I Explain the various steps I did.

First of all I've followed the steps to create the cold storage with two pc (online ad offline)
Then I've transferred some mBTC from a wallet web to the pc online and at this point point everything is ok.

Later I've created an unsigned transaction on the online pc:
1) Send -> compile the various fields
2) Preview -> I open a window with the summary of the data
3) Save -> save the unsigned.txn file and a pop-up window tells me that the transaction has been successfully performed.

After I've used the offline pc and I've transfered the file unisegned.txn:
4) Tools -> Upload transaction -> From file (and I load unisegned.txn file)

At this moment there's a problem: the window that appear and summarize the data has the Sign button (like the Transmission button) that is not enabled, so I can't sign the transaction.

I think the reason is the fact that the offline pc is not up to date with the first transaction in which I transferred some mBTCs to the online PC.

Am I wrong?
Why the button sign is not enable?
Please, can anyone help me?

Thanks!
