Hi All,
You are here because you need to export Bitcoin private keys from a Blockchain wallet.
Before reading the rest of that message make sure you understand the concepts of wallet, address & private key (there are plenty of useful resources on that forum).
Moreover ask yourself what you want to do with that private key!
The private key gives full access to your address and therefore to your funds.
Keep it secret and never give it to anyone! ANYONE!!Ok let's get started...
The Blockchain wallet is very easy to use and a like an exchange it allows users store, buy and sell Bitcoins without any technical knowledge.
That's great for most people and most cases but with simplicity and "user-friendliness" come the inability to access advanced features/options.
That's what's happening with the default wallet of the Blockchain wallet. Its addresses are bound to the wallet and cannot be used individually anywhere else without exporting the whole wallet with a third party tool.
I - Exporting the private key of an imported address It is very straightforward and available through the user interface.
1. Log on to your wallet
2. Click on "Settings > Addresses"
3. Find the address you want to export
4. Click on "More options > Private key"
5. Click on "confirm" in the warning window
6. You should now be able to copy the private key
Here is a screenshot to summarize the steps above:
https://ibb.co/c2XE7wII - Exporting addresses from the default walletAs explained above the challenge is to export the private key of an address from the default wallet as they are bound to the wallet.
Here is how to do so:
1. Make sure you have your seed phrase available (the 12-word phrase generated when you created your wallet)
Consider the seed phrase as precious and sensitive as a private key as it give full access to you wallet! Again keep it secret and never give it to anyone! 2. To extract information from your wallet you will need to use the following GitHub project:
https://github.com/iancoleman/bip39 3. Download the file called "bip39-standalone.html" (click on it, then click on the "Download button" and save the file)
4. Open that html file locally (does not seem to work with IE).
It works offline if you are more comfortable manipulating your wallet offline. 5. Change the number of words to 12
6. Input your seed phrase in the fields called "BIP39 Mnemonic"
7. Finally scroll down to the section called "Derived addresses", spot the address you are interested in and copy its private key
That's it.
I hope it helps.
