Title: Is there any guide on how to make bitcoin offline wallet? Post by: ~Bitcoin~ on October 07, 2017, 02:41:56 PM I know that there are many hardware wallet available right now also we can make paper wallet but what I am searching is a guide which have step by step process to make bitcoin transaction using paper wallet details and without exposing my private keys online.
Suppose I have paper wallet printed from offline computer and printed it out from offline printer. Now I want to transfer half of bitcoin from it, I know I can import that paper wallet in other wallets like blockchain.info or sweep private keys in electrum but I don't want to expose my private keys anywhere online. So I want a guide where it will have step by step instructions on how to send half bitcoin from that paper wallet without exposing my private key...

This thing makes your private keys secured but meantime you can't-do that since a wallet needs internet to send. But I dunno if there are existing ways to do that, coz that's all I know.

No I am talking about signing transaction with my private key offline and broadcasting them through online computer or wallet. I have heard somewhere this can be done via electrum or bitkey. Couldn't find any reliable guide till now to do it in right way...Title: Re: Is there any guide on how to make bitcoin offline wallet?

Write down your seed, and go to Wallet -> Master Public Keys -> Copy your master public key and save it on a pendrive. 2. Go to your online PC, create a wallet with Electrum but select "Use public or private keys" -> Put there your xpub -> This is your watch-only wallet that will build the transactions, while the offline will sign them. When you want to spend: 1. Open your watch-only wallet -> go to "Send" as usual and make your transaction -> Click preview -> Click "Save" and save your transaction in a pendrive. 2. Go to the offline PC -> Open your offline wallet -> Go to Tools -> Load transaction -> From a file -> Select the txt file with the transaction you saved in the pendrive. 3. Click "Sign" and save the signed transaction in the same pen drive. 4. Now go to your online PC wallet again -> Tools -> Load transaction -> From a file -> Select the signed transaction -> "Broadcast"; Congrats! Your transaction has been sent ;) |
