Backup & Restore | Ethereum Frontier Guide
DO NOT FORGET YOUR PASSWORD and BACKUP YOUR KEYSTORE Everything geth persists gets written inside its data directory (except for the PoW Ethash DAG, see note below).The default data directory locations are platform specific: Accounts are stored in the keystore subdirectory. The contents of this directories should be transportable between nodes, platforms, implementations (C++, Go, Python). To configure the location of the data directory, the --datadir parameter can be specified. See CLI Options for more details. Note: The Ethash DAG is stored at ~/.ethash (Mac/Linux) or ~/AppData/Ethash (Windows) so that it can be reused by all clients. You can store this in a different location by using a symbolic link. Sometimes the internal database formats need updating (for example, when upgrade from before 0.9.20). This can be run with the following command (geth should not be otherwise running): Geth's blockchain and state databases can be removed with: This is useful for deleting an old chain and sync'ing to a new one. It only affects data directories that can be re-created on synchronisation and does not touch the keystore. Export the blockchain in binary format with: Or if you want to back up portions of the chain over time, a first and last block can be specified. For example, to back up the first epoch: Note that when backing up a partial chain, the file will be appended rather than truncated. Import binary-format blockchain exports with: See for more info And finally: DO NOT FORGET YOUR PASSWORD and BACKUP YOUR KEYSTORE Continue reading >>

I've Sent Ethereum To My Ethereum Classic Address!
I've sent Ethereum to my Ethereum Classic address! Ethereum (ETH) and Ethereum Classic (ETC) are two separate currencies. However, the addresses are identical in format, so it's very easy to accidentally send ETH to ETC and vice versa. If you do this by mistake, your transaction will show confirmations, but your funds will never appear in your wallet. However, don't worry! Your funds are safe and fully retrievable! As of Exodus version 1.43.1, we now include the ability to perform cross-chain sweeps automatically without having to manually import and export private keys. This method of recovery is preferable, as it ensures the safety of your private keys and significantly simplifies the process of reclaiming your "missing" assets. It is also a security risk to export your private keys, so we have developed this new, fully automated method. Here's how to do recover your "lost" assets in three simple steps: Open theDeveloper Menuin Exodus.For a guide on how to do this, please see here: Determine what assets need to be recovered: If you've accidentally sent ETCto anETHaddress,you want to select "Ethereum" in the Developer menu by navigating toDeveloper > Assets > Ethereum. If you've accidentally sent ETHto anETCaddress,you want to select "Ethereum Classic" in the Developer menu by navigating toDeveloper > Assets > Ethereum Classic. To recover yourETC, click "Sweep for ETH Classic" in the Developer Menu the as shown here: Recover ETHsent to your Ethereum Classic Wallet To recover your ETH, select "Sweep for Ethereum" in the Developer Menu as shown here: That's all there is to it! Your funds will be in your wallet after running this process. Continue reading >>
How Can I Reverse Or Cancel A Transaction Or Recover Lost Ethers?
How can I reverse or cancel a transaction or recover lost ethers? Transactions (using a smart contract like a token or sending ether), by design, are immutable on the blockchain. What methods can be used to (more or less) unilaterally reverse a transaction made by myself or someone else? Situations where one might like to reverse a transaction: Sent a transaction to the wrong account/wrong contract/wrong address. Sent a transaction with the wrong amount of ether. Buyer's remorse (e.g., transaction recipient was a scammer). Recipient is not acknowledging transaction or is holding on to tokens/ether sent as part of the transaction (such as an exchange might). Transaction is "stuck" due to low gas and no longer worth performing. The question is phrased in a weird way that gives the impression that you already know what answer you're expecting (a.k.a. a rhetorical question). As it turns out, you're answering to it yourself. I get the idea that it doesn't matter who asks and who answers as long as the question and the answer are useful, but in this very case the question is not, which makes the answer not really useful either. I have an uncomfortable feeling that you're stretching the Q&A format maybe a bit too much here. David Ammouial Sep 6 '17 at 1:31 I always phrase my questions in a weird way :) But more seriously, I normally include a bit of context in all of my questions to show how much/little work I've done to answer my own question so that someone answering the question has an idea of what level to aim the answer at. Self-answering policy for stack exchange is here: stackoverflow.com/help/self-answer . As for the question not being useful, something like this pops up once or twice a week, but indirectly or as part of another question. Also, I set my answer as a wi Continue reading >>
Samhain Labs | How To Recover An Ether.li Wallet
How to recover an ether.li Ethereum wallet By Rainer [email protected] (last update: Mar 04, 2018) Ether.li is a web service that lets you create an online wallet which you can use for receiving and sending Ethereum (a cryptocurrency, in case you're unaware of it). Ether.li claims that you can recover your wallet if the Ether.li service ever becomes unavailable. First, as of today (Jul 5, 2017) ether.li still works. However, it seems that you cannot sign up for a new account anymore. Second, while it is true that you can recover the wallet, it will be very difficult once ether.li is offline unless you take precautions now (see the warning below). The Ether.li wallet is a two-of-three multisig wallet, which means that is has three owners, and every transaction needs to be authorized by two of these three owners. The three owners are: Your user account (created for you upon wallet creation) Your recovery account (created for you upon wallet creation) In normal operation, you initiate a transaction at the Ether.li site with your user account, and Ether.li will confirm it with their account (after it sent you a confirmation SMS and you typed in the received pin). Without Ether.li, you would initiate a transaction with one of your two accounts, and confirm it with the other. Because an Ethereum account can be recovered with (only) the private key, what you need is: WARNING: upon wallet creation, Ether.li shows you the user account key in encrypted form. The format of that encrypted key is NOT standardized, and other Ethereum software may NOT recognize it. If you want to be sure you can recover your wallet, go to NOW, decrypt your user account key and write it down (in triplicate, if you do it by hand - to guard against typos and bad handwriting). One of my rea Continue reading >>

Accessing Your Ether Wallets Private Keys On Blockchain.info
Accessing your Ether wallets Private Keys on Blockchain.info Currently, many companies support creation and use of Ether wallets. Its possible to send and receive ETH easily, without being need to download the whole Blockchain for the task. However, many of these wallets havent added support for ERC-20 tokens. These tokens are used often as a trading value in many ICOs, and also given to the users as payment for their contribution. With Chronologics ICO it wasnt different. There are steps to be taken to visualize and use these tokens for some wallets. Now, lets talk about the wallets that really allow users full control over their address. Among them we have Jaxx, MyEtherWallet, Blockchain.info, and others. If youve made your contribution from any of these rest assured that with a few simple steps you can manage and even transfer your DAY tokens. However, if youve sent your contribution from Coinbase, Bittrex, Poloniex, FreeWallet, BTC Markets or Kraken, among others, then you have a problem. In order to check the DAY tokens inside your ETH address, you dont need to unblock/open your wallet, rather only type your wallets address on EtherScan.io or Ethplorer.io. Now, if you really want to move your DAY tokens, or any other ERC-20 asset from those wallets, then youll have to access it using the Private Key, JSON file and password, etc. Today well feature a quick tutorial on how to recover your Private Key from an Ether wallet hosted by Blockchain.info. Step #1: Login into your Blockchain.info account. Step #2: Click on Ether (left side of your screen). Step #3: Select the option Export Private Key, as demonstrated below. Step #4: This warning mentions the implied risks of exposing your Private Key. Basically, never let anyone else see it and always double-check the websi Continue reading >>
Ethereum Restore - Crypto Mining Blog
All About BTC, LTC, ETH mining as well as other alternative crypto currencies How to Backup Your Ethereum Wallet and the Blockchain Just like with Bitcoins wallet.dat file that contains your wallet address and keys and that you need to backup for safety reasons, Ethereum also has a similar wallet file that you should have a spare copy of. With Ethereum the wallet file has a bit weird name and is not just called wallet.dat, but it has essentially the same purpose and the file works essentially the same way as the wallet.dat with Bitcoin and many other alternative crypto coins. Ethereums wallet file is stored in the data directory used by the client to store the blockchain and other files, the default locations for the datadir on different operating systems are listed below. Windows: %USERPROFILE%\AppData\Roaming\Ethereum To get the full path of the data directory on your specific system you can run the geth console and type admin.datadir and you will see a result like on the screenshot above with the full path. Note that the wallet file is not stored in the main datadir folder, but is instead placed in a separate folder under it called keystore. Inside that folder you should see a file with a long name starting with UTC--2015..., this is the wallet file you need to backup. Do note that aside from the wallet file itself you will also need to remember the password (or also back it up along the wallet) that you set when creating your account, without the password needed to unlock it the wallet file wont be of much use. If you are moving your Ethereum installation over to a different computer or want to have a copy on another system for solo mining for example, aside from a copy of the wallet file you may also want to make a copy of the blockchain, so that the geth client w Continue reading >>
Restoring Your Ethers (eth Or Etc) Without A Ledger Nano S
Restoring your Ethers (ETH or ETC) without a Ledger Nano S We published a patched version of the original BIP 39 recovery toolto let you recover your Ethers without a Nano S, using your BIP 39 backup seed. You can also use this method to split funds if you mixed ETH/ETC on the same Nano S address. Make sure you're running the recovery tool on an offline, trusted computer. You'll be exposing your seed which means all applications can be compromised, not just your Ethers. Launch the standalone BIP39 tool (the online version is , using it is possible but could expose your secrets to any malware) To obtain your ETH private key : select Ethereum in the Coin menu, select the BIP32 tab (not the BIP44). In the field "BIP32 Derivation Path" enter:m/44'/60'/0'/ Read the first derived private key (m/44'/60'/0'/0) - To obtain your ETC private key (Chrome app above 1.0.5) : select Ethereum Classic (Ledger transitional 1.0.5) in the Coin menu, and read the first derived private key (m/44'/60'/160720'/0'/0) - If you used the Chrome application before 1.0.5, the ETC private key is the same as the ETH private key. You can use this method to recover the private key, and use MyEtherWallet to split the funds to a new address generated from a new seed. After obtaining your private key, you can use any Ethereum wallet to import your funds, such as MyEtherWallet (for both ETH/ETC chains), Jaxx (ETH), Parity (for both ETH/ETC chains) or full nodes such as Geth (for both ETH/ETC chains) ... Note that MyEtherWallet expect your private key to be entered without the leading "0x" - to use it, go into the "Send Ether" tab, copy & paste its value, and select "Unlock Wallet" Continue reading >>
Bitcoin Data Recovery | Litecoin Wallet | Ethereum Password Recovery
Bitcoin, Ethereum and Litecoin wallets are encrypted. However, sometimes owners forget or misplace their wallet password. Unless you have the password, you have no way to access any funds stored in that wallet. That crypto currency is lost forever. We have created a recovery wallet service that can take your wallet files, your best guess at your remembered password/passphrase, and attempt a brute force decryption of your wallet. For this service to work you need to give us variations of what you think the password is. If you dont have an idea of what your password is then we cannot help you. We can decrypt all the major wallets including Bitcoin, DRK, Litecoin & Ethereum wallets. Tell us about your issue and we'll get back to you. I had lost 4 years uni work on a 500gb WD Passport drive, I panicked a bit as I really needed the data but Advanced Data Recovery recovered all data. Expensive lesson not to have a backup in place but a quality service. There was 6 months Pictures and Video on my damaged iMac computer. I took it to Apple to get serviced and data recovered but Apple store could not do anything and recommended Advanced Data Recovery. Data recovered within 48 hours and backed up onto data DVD. Thanks for recovering my data. My HP Pavilion business laptop would not boot up. Took it to a local PC shop and they removed hard drive and tried to read it from a HDD Caddy. They could not read it and recommended Advanced Recovery. I dropped it into Covent Garden branch and booked it on a critical recovery service. Disk was diagnosed within 3 hours and data recovered within 24 hours. An expensive service but a full recovery. My vat returns will be made on time for a change! We run a graphics production studio in Westminster. Our Synology multi disk raid NAS system became Continue reading >>
How To Recover A Lost Wallet #396
As long as you remember your account password this might not be a problem. Your wallet and keystore data will be stored in %APPDATA%/Ethereum. Type that into a command-line shell to see the full path. I recommend making a backup copy of the keystore folder in there (as explained in ). After doing that you could try deleting %APPDATA%/Ethereum and then running the latest Mist (0.5.2) to recreate the folder with fresh data. You could then copy your keystore backup into the new %APPDATA%/Ethereum and restart Mist to see if it picks up your account. this is really frustrating, my computer crashed, I reinstalled the OS thinking if I have the password and the address I will be fine, I am not a computer geek, does this mean I lost my ethereum, all? I invested a lot of money in this technology and now I am told that I lost it all. I have my password which I thought it will be enough to "log in" back if I reinstall the wallet, I never knew this is a completely different technology which is not based on logins and I have never been prompted by any popup RED BIG saying: please save your wallet etc.!!! so, the questions is, what now? I just lost a few thousands ethereum?? Sigh, what a joke. When I used geth in February 2016, there was no mention that the software would put a private key in some random folder on my computer, while also downloading the entire ethereum blockchain. Well no duh I decided to delete a 10gig + folder on my hard drive when I needed space and was not an ethereum miner. All it said was to guard the password with my life. No mention to guard the private key with your life. No mention of putting super important files in a completely random directory. When people like myself or others are trying to promote Ethereum, we lose all our eth due to terrible documenta Continue reading >>
How To Recover Ethereum (eth) On A Mist Wallet That Won't Sync And Import It Into Myetherwallet
I had a little over 1 Ether in my Mist wallet worth over $400 and I was having trouble syncing my wallet on my Mac. I tried several times and it got as far as 43% and then it would cease. It got quite frustrating. I searched the web and there was a lot of confusing information that was not very helpful. The easiest way to recover Ether without worrying about your wallet syncing is by first, backing up your Mist wallet (this has your encrypted address and Private Key) to a flash drive or to your computer. If you don't know what a private key is, it's your password to your Ether address. How to back up your Mist Ethereum Wallet: Go to "ACCOUNTS" at the top of your wallet, select "BACKUP" and select "ACCOUNTS" again. All of your accounts will pop up in a window in your KEYSTORE folder. If you only have one account (ethereum address), there will be only one account in that folder. Back up this Keystore folder to a USB or to your computer. Open up that Keystore folder and you'll see your Ethereum address usually starting with for example: "UTC..Ox5a00...." (this contains your Ethereum address and encrypted Private Key). You will need your Mist password in order to upload this wallet into MyEtherWallet.com. Go to MyEtherWallet.com. Select "VIEW WALLET INFO". Then select "KEYSTORE FILE (UTC/JSON)". Click "SELECT WALLET FILE" (Please See Photo Below). Go to where you backed up your Keystore file like stated above, either on your USB or computer (the file starting with UTC...Ox....). Enter your Mist Ethereum Wallet password. Now you should be able to see and access the Ethereum in your wallet. Another great thing about MyEtherWallet is that you can also see your private key! So make sure you save your Ethereum address and private key just in case. I was able to send my Ether in Continue reading >>
How To Import My Jaxx Or Exodus Mnemonic Into Coinomi?
How to import my JAXX or EXODUS mnemonic into Coinomi? Modified on: Sun, 4 Mar, 2018 at 5:46 AM Our security has been fiercely battle-tested since 2014, and no user has every been hacked using our wallet. In order to import your mnemonic from Jaxx, Exodus or any other compartible wallet to Coinomi, please first identify your case: - I just installed Coinomi, I'm at the first screen, what do I do? 2. Enter or scan your 12-word mnemonic. Click "Next" Note: You can add an additional BIP39 passphrase in this step. Consult this and this article before doing so, and remember: While you can always view your Recovery passphrase inside Coinomi by going to .../Settings/Show Recovery Phrase, you will not be shown your extra BIP39 phrase - only a message that it is enabled. Therefore, make sure you save your extra BIP39 passphrase and keep it safe, should you choose to enable it. 3. Enter a strong password, and re-type to confirm. Click "Next". Note: The application will prompt you to enter a stronger/more complex password if your current choice does not meet Coinomi's minimum entropy requirements. Do NOT press "Skip" in this step, as without this password your passphrase will remain unencrypted on your device, voiding any other security measures you or Coinomi takes to protect your funds. (The "Skip" option will be removed in one of our future releases completely.) 4. From the Coins list, select as many Coins as you would like to create wallets for. Include the ones you had with Jaxx/Exodus or other wallet. Note: If you forget one, you can always add it manually later by going to Menu/+Coins and selecting it. If your mnemonic contains keys to a coin that is not currently in our coins list, it will not show up in Coinomi. Make sure you manually send the funds to an exchange or oth Continue reading >>

How To Recover The Sent Eth On An Etc Address?
If you have mistakenly made an ETH withdrawal from your Gatecoin account to an external ETC wallet address, you can recover them using one the following options: 1. Since the ETC chain is a fork of the ETH chain, any private key on the ETH chain is equally valid on the ETC chain and vice versa. Therefore, you can run an Ethereum client on the ETH chain and import the address that holds the funds and the ETH balance will show up under your wallet. 2. If you're currently not running your own ETH/ETC node and this is an address you never plan to use again you might consider using MyEtherWallet.com and import the private key of your address. You will be able to import your keystore file into MyEtherWallet and the ETH which have been wrongly sent to your ETC address should appear. You can switch between the ETH/ETC chain in the website and you will be able to see your balance in each chain. If you decide to go for the second option, please make sure to follow MyEtherWallet's general safety tips to double check the URL and the SSL certificate to make sure that you are on the official website.
