Your bitcoins are lost forever, unless you have the key. Let this be a lesson learned to always write down your keys on paper. There are no ways to recover your bitcoins without the key.

I recently recovered an old wallet.dat file using pywalley.py and Electrum, which allowed me to read the wallet and sweep the coins to a new Electrum wallet. Steps: Get the jackjack pywallet https://github.com/jackjack-jj/pywallet Put the wallet.dat in that directory ./pywallet.py --dumpwallet --datadir=. --passphrase=PASSPHRASE Passphrase is optional, ...

If you are missing the first word and you know the rest of the 11 words, there are 2048 possible mnemonics but only ~128 of them are valid. Using Python and this library you can print all the valid ones with this simple script: from cryptotools.BTC.HD import check, WORDS phrase = "{x} decrease enjoy credit fold prepare school midnight flower wrong ...

There are different "backup-standards". Some use BIP39 (mnemonic) which lacks a flexible wordlist and versioning. It's used by Ledger, Trezor, Bitpay/Copay, etc. Electrum uses a different – more flexible – mnemonic backup concept which is incompatible with BIP39. There is also the BIP32 keypath which can be different among wallets. Example: you can ...

If you're programming savvy you could write a small program that searches for the regular expression of a Bitcoin private key. Bitcoin private keys have a very specific format: They are 51 keys long, start with a '5' and the second letter is either 'H', 'J', or 'K' and use base58 for the remaining 49 letters which excludes the characters 0IOl. It seems to ...

You need your 12 words to get it back. Just that. There is no other way. No bank, no insurance company and no helpdesk that you can turn to. No person or computer in the world is able to recover the same wallet without those 12 words. I hope you've written the words down somewhere. Here's where the relevant part of the answer for you ends concerning the ...

Depending on what kind of phone you have and depending on what program you used to store your words, you may be able to find a copy of the data on Google Drive (Android default), OneDrive (Microsoft default) or iCloud (Apple default). If you never disabled these services, but do have an account for them, they're probably turned on. Log in online using the ...

Are you talking about the people who mined or bought bitcoins in 2009 - 2011 and are surprised that the price is that high now? HD-wallets (wallets with such a recovery phrase, it's called seed) are available since BIP 32 and that was around 2013. So they don't have such a wallet and can't recover anything. That's why they search their old hardware.

Can I recover btc sent to an incorrect address? Confirmed Bitcoin transactions cannot be cancelled, reversed, undone or recovered. The only person who can give you your money back is the recipient, by creating a new transaction to send the same amount back to you. I realize now that I had a malware copy of electrum If the initial mishap was due to a ...

First, don't panic! Second, make an image backup of the wiped drive to a physically different drive. Third, you maybe able to recover the deleted files with tools such as magic rescue so long as the sectors on your drive that your wallet was wiped from are intact... otherwise you may be out those coins... I've had OK luck with rescuing data off drives for ...

In my case I sent the Bitcoin Cash to an address created by a Mobile Bitcoin (!) wallet from btc.com. The support from btc.com told me the solution: B) You have sent BCC to your BTC wallet: 1. Use your BTC recovery PDF at https://bcc-recovery.btc.com/ (click on 'forgot password' to use your backup PDF) 2. Recover the coins to an address from your BCC ...

Firstly, it is highly recommended not to use a brainwallet, your coins will be stolen. But in general, if you have a private key, there is no way to obtain the 12 word recovery phrase from it. That is because the 12 word phrase is used as a seed to generate a hierarchical deterministic master extended private key, as described in BIP 39 and BIP 32 and this ...

All of the information in the screenshot is publicly available. And no, they won't be useful for recovering your Bitcoin. If you used Electrum, you either need the wallet, the recovery phrase(seeds) or the private key(s) to recover you Bitcoins. Note that when you first create your wallet, you are instructed to write down the seed (12 or 13 dictionary words),...

Can I “duplicate” a wallet using a backup phrase (12 words)? Yes Where is my balance stored? Both wallets will scan the relevant parts of the public transaction-journal ("blockchain") to add up the amount of money controlled by the keys derived from your backup phrase - this total is your balance. Wallets are very likely to store this total ...

Ben Kaufman answered this on Twitter. The main caveat in a multisig wallet is that, while you need only a threshold of devices (ie. 2 of 3, 3 of 5, etc.) to sign a transaction, losing access to even a single device could potentially prevent you from being able to spend the funds - if you don't back up properly! The reason is that (usually) in order to make a ...

Your wallet shows empty because it doesn't really "know" that one or more addresses that it controls "owns" some bitcoins because you manually deleted the blockchain files. It will display your correct balance once it synchronizes again, provided of course that you have not deleted the .wallet file. I would also suggest you take extra care when deleting ...

Yes. Trezor uses BIP39 and is compatible with any other wallet that would. You can in fact import your seed into electrum, though this to some extent defeats the purpose of having a hardware wallet.

Bitcoin and Bitcoin Cash use the same address format. This means that if you take the key from your Bitcoin Core client, and import it to your Bitcoin Cash client, the Bitcoin Cash client will be able to spend that money. However, if someone else operates the Bitcoin Core client, you need to convince them to send you the money.

Jaxx uses a different derivation path than Coinomi when handling ETH. Coinomi opted for the path as described in the ETH specification. Ledger has the same scheme as Coinomi. Jaxx: M/44H/60H/0H/0 Coinomi: M/44H/60H/0H You will have to do the following: Delete any existing ETH wallets you have added by long pressing them (2 sec) in the Overview tab and ...

This is impossible. The whole point of public key cryptography is that the public key can be shared with anybody, without compromising the private key. If there were a way to recover the private key using the public key, this would all fall apart, and in particular Bitcoin would be horribly insecure. This hasn't happened. The public key could be used ...

Bitcoin Core does not currently support BIP 39 mnemonics nor the size of the BIP 32 seed produced by a BIP 39 mnemonic. BIP 39 produces 512 bit seeds, but Bitcoin Core currently only supports importing a 256 bit seed via sethdseed.

I am assuming that you are talking about BIP 39 here. A BIP 39 mnemonic can have any number of words with the most common being 12, 18, and 24 words. There is a checksum encoded into this mnemonic. This checksum is actually just a "part of" the last word, i.e. the last word encodes some of the actual initial entropy, and some of the checksum, depending on ...

In c-lightning the per commitment point is derived from the hsm_secret using per_commit_point from: The node id / public key (can be found with listfunds, until the channel is purged some time after closing) The channel database id (can be found with cat ~/.lightning/debug.log | grep $node_id), shown as chan #$node_id The commitment number (0 when opening ...

What can I do? You could find tools that automate the trying of various combinations of seed-words. Some are mentioned in similar questions here. For example btctools, btcrecover.

I understand these wallets only work with provider's mobile app, online interface or their computer software, correct ? No. Some of the most popular hardware wallets are supported by third party software. For example, Trezors and Ledgers can be used with Electrum who have implemented support for these devices directly. Other wallet software like Wasabi ...

Recovery using a private key If your private key looks like a proper Bitcoin private key, you can recover control over your money. A private key is just a large number. There are several different ways of representing that number. Representation Example Hexadecimal E9873D79C6D87DC0FB6A5778633389F4453213303DA61F20BD67FC233AA33262 Base58 WIF ...

The default MultiBit HD wallet uses an address generation scheme known as BIP32. Mycelium uses an address generation scheme known as BIP44. BIP44 is what Trezor uses. HD wallet interoperability is unfortunately a bit thorny. It's normally easier to have two wallets.
