How to generate your very own Bitcoin private key


Before you import your private keys consider whether sweeping them might be better. Importing your private keys requires you to create a new electrum wallet just for your private keys.

Sweeping them means that all the funds in the private keys are sent to your existing deterministic Electrum wallet.

This is a one-time on-chain operation. Unless you expect to receive money in the future to the addresses corresponding to your private keys it is better to sweep them. Sweeping private keys sends the funds to your deterministic wallet and backing that up is as easy as writing down the seed mnemonic.

These instructions are for Electrum 3. Please upgrade first if you are using an older version of electrum. You cannot import private keys into an existing HD wallet. Importing private keys requires you to create a new wallet file that will only contain the imported private keys.

Enter one private key per line. Click on the info button to see examples. If you need help with your Electrum problems see the support forum links here. What version of electrum are you using?

The version is listed up top in the electrum window title bar. Version 3. Is this normal? I gave you instructions to follow on IRC but you ignored them and disappeared. There is a bug in blockchain. So what you can do is load bitaddress. The uncompressed private key starts with 5. Then close your browser before you go online again.

After that you can import your uncompressed private key into electrum to get the correct address. Note that entering your private key on a website is risky so you should just send the money from your blockchain. Electrum acces Is asking me 0. Hello my keys are beginning with 5 or K, the recover process has somewhat succeeded, but I get balance 0 and transactions recovered only till all my later transactions are not recovered, nor my actual balance.

However it is also possible that your coins are in a different address controlled by a different private key. Perhaps whatever wallet software you were using would have had multiple private keys and it moved the coins to a different address like a change address. I will try to change server. Will sweeping my private key fix this and what prepend would I use? Apologies in advance if I just overlooked the answer. Most likely your bitcoins are in a change address like I said before.

What you need to do is extract the seed words and restore using that in Electrum. Hi, here my strange situation: — i have a blockchain web wallet whit actually balance 0. The remaining coins are probably in a change address. Do you have the recovery phrase for your bc. If you have an old bc. However when it comes to old bc. Thanks for reply, the true is that was my mistake im an idiot ahaha because bc.

However the child transaction will not confirm until the parent transaction has confirmed too. But on Electrum wallet is not unconfirmed, in fact this transaction not exist and btc back to wallet.

Only in blockchain. That server has obviously dropped your transaction. However other nodes may still remember this transaction of yours.

You can try spending these coins. If enough nodes have forgotten your old transaction the new one will be relayed successfully. I am logged in to my Electrum desktop wallet, but no longer have access to my 2FA or seed. Need real help. In December, was create a new Electrum wallet already used it several times before , saved 12 seed words with a QR code by print screan, did two factor authentication it is a big problem now , send BTC there, left for a couple of months.

Decided to pull out, enter the address of the departure — asks 2FA. I lost my phone, I do not have it. Okay, I think, it does not matter. Restore without 2FA on Seed. Restore — 0 Balance.

Cold sweat. What the hell … there is a saved wallet. Restore — everything is ok. There is access to it. I can watch, see, but I can not get them out, since I have lost 2fa — There are 12 seed phrases — but it is restored with 0 balance and with other addresses I tried it in different ways, including QR code. By the way, I tried to restore the wallet by QR on blockchain. At the same time, I can not double-check — it is not available in Electrum — there is a file wallet.

SyntaxError: invalid syntax — The only success, I was able to add the address not the purse, namely the one on which btc lies in the address column Electrum to blockchain.

In order to translate btc from blockchain. In general, straight some trouble. I see, I look, I can climb magic, but I can not get it out. Straight sheet Thank you in advance. Please help me!!! Nevertheless I suggest you update to the latest version of electrum 3. If non of the above steps fixes your problem you should contact trustedcoin the co-signing company and ask them for help resetting your 2fa. Their site is at trustedcoin.

I just installed and started using electrum, didnt read instructions and somehow ended up with a watchonly address, transferred funds to that address.. Can someone help? Good afternoon this is a question of topic and hopefully you can help me out? Thank you!! I have the same problem, the only difference is that I created the wallet in Blue wallet. Now I want to acces these funds by importing my seed in Electrum. Does this give me acces to all coins under this seed?

So on Legacy adresses, Segwit adresses and Native Segwit adresses stored under the same seed? Or do I have to export my wallet on my Coldcard and upload this in Electrum? It should import at least my actual balance but only imports old records with zero balance. You need to restore using your seed words. Great guide and support from Abdussamad! The steps I have taken so far: 1. This has provided my with keys starting with L or K. Also setup a password. It found my default wallet and asked for the passphrase, which was accepted.

Not sure what to do.. Im thinking of uninstalling and trying again, but using the Sweep feature instead next time. This site is for electrum not electron cash. However the solution to your problem is simple. Simply follow the 1st step of the guide above to create a new wallet file and then repeat the private key import process again in that wallet file. Like I said this site is not for bitcoin cash wallets. Can you export the private key from the existing wallet to the new wallet on the same laptop?

Or do they have to be on different laptops? It can be on the same machine. But you may want to restore using your seed words instead. That way you get all the private keys in your wallet. I do have a lot of difficulty trying to use Electrum on a laptop, with an un-encrypted wallet.

Why am I doing this?

Bitcoin uses cryptography to create a key pair that controls access to bitcoin on the blockchain. Each bitcoin key pair consists of a public and private key. A bitcoin private key is simply a large bits secret number that allows bitcoin to be unlocked and sent. Each private key creates a unique signature that authorizes the transaction of bitcoin for the owner. A bitcoin public key is another large number but allows bitcoin to be locked and received. People can over-complicate explanations by trying to explain digital signatures, signing transactions, and wallet import formats. These two keys or numbers are related mathematically on the secpk1 elliptic curve. The private key is a randomly generated number plotted on the curve, and the corresponding public key is a related point on that curve.

While paper wallets are a very secure way to store your cryptocurrency, you will at some point want to access those coins. Thankfully, while the process may not be particularly intuitive, it is simple to execute. The most common way to obtain a paper wallet is by purchasing bitcoin, litecoin, or another cryptocurrency at a bitcoin kiosk. A paper wallet will display two key pieces of information: a private key and a public address. As this is the key you use to send bitcoin from the wallet, it is extremely important that you keep it secure and secret.

Signing can for example result in executing a smart contract , a cryptocurrency transaction see "bitcoin transaction" image , identification or legally signing a 'document' see "application form" image. A crypto currency wallet works by a theoretical or random number being generated and used with a length that depends on the algorithm size of the cryptocurrency's technology requirements. The number is then converted to a private key using the specific requirements of the cryptocurrency cryptography algorithm requirement.
