What Is The Recommended Way To Safely Store Ether?

What Is The Recommended Way To Safely Store Ether?

There are several options for storing Ether : Icebox Air gapped offline signing of transactions In short there are a lot of options. So my question is is there an official recommended way of securely storing Ether? If the answer is 'Multi-signature' how should this be backed up (both files & printing the wallet address on paper) and how should the accounts which control the wallet be created and backed up. related question: ethereum.stackexchange.com/questions/1216/ Paul S Feb 11 '16 at 2:08 @JackWinters: I think it's close to being criminal that people consider that a website is an acceptable way to create a paper wallet. For all we know, even if the site looks fair, one time out of 50 it may decide to send a backdoored version to the user. The website could also be hacked and serve a backdoored version to anyone visiting the site during the compromise timeframe, etc. There are secure ways to create paper wallets. Using a website ain't one of them. Cedric Martin Feb 17 '16 at 1:37 A lot has changed since I first asked this question so we probably need some updated answers and some meta discussion. e.g. Should the accepted answer be a community wiki. (This would make it more live but it could also potentially introduce additional security risks since someone could edit the wiki to link to malware or to include deliberate bad advice) JackWinters Dec 7 '16 at 21:25 I believe the Ethereum team recommends using official clients, like Mist or Geth. This makes sense. I recommend that people use whatever tool they can understand best and use with confidence. I do NOT believe that recommending someone who has never used command line to use geth. There's too much room for error and it deters people from investing and getting involved. Regardless of what tool you use to create a Continue reading >>

Best Ethereum Wallet (2018 Update) 5 Options Reviewed

Last updated on November 24th, 2017 at 08:15 am Ethereum, the blockchain platform that allows smart contracts, is becoming more and more popular.Since the beginning of 2017 the price has spiked from $8.22 to around $50. Ive covered how to buy Ethereum in a previous post but thats only part of the process. Today I want to cover 5different types of Ethereum wallets so you will know where to store your Ethereum. Ethereum is a very technical currency (even more than Bitcoin), therefore most wallets out there arent newbie friendly. I will go over them from the simplest to the most complex so you can choose the one that is best suited to your knowledge level. Hardware wallets Best security (for a price) If youre serious about securing your altcoins I suggest storing your Ethereum on a hardware wallet. However these hardware wallets arent free and cost anywhere between $50-$100 (shipping not included). Todays leading hardware wallets TREZOR , Ledger and KeepKey all supply you with the option to store Ethereum on them. Instead of explaining about each one Ill just link to my previous reviews on the wallets: Personally, I use a TREZOR but all three are excellent choices for maximum security. Coinbases Ethereum wallet The simplest option Coinbase supplies an Ethereum wallet as well as a Bitcoin wallet. Coinbases wallet is simple to set up and very easy to use, however it has a few limitations youll need to be aware of: The company holds the private key ofthe wallet for you. This means youre not in control of your funds and Coinbase can decide to shut down your account if they want to. There were cases in the past that Coinbase shut down user accounts do to illegal activity. The Coinbase ETH wallet doesnt support ETC (Ethereum Classic). For a simple explanation about ETC vs ETH r Continue reading >>

How To Make An Ethereum Paper Wallet

How To Make An Ethereum Paper Wallet

In the cryptocurrency world, a wallet is a digital medium that is used to store, send and receive money which in this case is in form of cryptocurrencies. Unlike the real world wallets, a crypto wallet does not really store money but will instead save the private and public keys that you will use to do a money transaction. Both public and private keys are in form of addresses whereby the public key is an address that one can use to send you money while a private key is the address that you use to send money. Both your private and public keys are stored in the blockchain but it is our responsibility to make sure that your private key is as secure as possible so that no one but you can use it to send Ethereum to another address. In the world of crypto wallets, there is either hot storage or cold storage. Hot storage is whereby your wallet has access to the internet. On the other hand cold storage is whereby your wallet is completely offline. Most people believe that cold storage is the safest since it is safe from hackers and cybercrime. It is however inconvenient in the sense that it is not ideal if you need quick and daily transactions. Paper wallets are a form of offline cold storage for keeping your cryptocurrencies. Normally you will need to print both your private and a public key on a piece of paper then its upon you to make sure you store it well. The keys are not printed out in form of addresses but in form of QR codes which you will have to scan if you have to do any transaction. There have been many arguments on whether it is the safest way to store crypto coins, with some arguing its safe and some arguing its not safe. It may be safe in the sense that its the responsibility of the owner to make sure that it is safe and the private key is not leaked out to som Continue reading >>

Wallets - Ethereum And Blockchain Resources

Wallets - Ethereum And Blockchain Resources

Resembling fiat currency bank accounts, Ether wallets are used for holding, storing, and transferring Ether. The Ethereum platform allows you to create a wallet for yourself, but it is easier to use a third party to do this. Third-party wallet providers are available through a software application, website, or other mechanism. Wallet providers give the user their public key, which is their Ether address. The wallet also utilizes the users private keys, which unlock the wallet and allow the user to spend the Ether thats allocated to that address within the blockchain. Also similar to a fiat bank account, these wallets hold a users balance and provide storage and transaction history. As a part of the Ethereum platform, entities can view your balance and transaction history but not access it, and your identity is kept anonymous. Wallets can come in different forms such as a mobile wallet, a desktop wallet, a wallet that is stored on the web, or even a tangible hardware wallet. These various wallets fall into two categories: Hot Storage Wallets and Cold Storage Wallets (there can be hybrids of hot and cold, as well). A hot storage wallet refers to a wallet thats kept online. Hot wallets are generally more vulnerable to hacking and theft due to internet access. A cold storage wallet refers to an offline wallet (something thats not connected to the internet, and can be in a tangible form). Cold wallets are intended to help protect the stored Ether against hacking and theft, due to the inaccessibility of the internet. Exchanges may offer built-in wallets with their servicesor a user may select their own from a different provider. There are many wallets available for virtual currency users. Listed below are a few of the more popular wallets used for storing just Ether. Continue reading >>

How To Store Your Bitcoins - Bitcoin Wallets - Coindesk

Bitcoin wallets store the private keys that you need to access a bitcoin address and spend your funds. They come in different forms, designed for different types of device. You can even use paper storage to avoid having them on a computer at all. Of course, it is very important to secure and back up your bitcoin wallet. Bitcoins are a modern equivalent of cash and, every day, another merchant starts accepting them as payment. We know how they are generated  and how a bitcoin transaction works , but how are they stored? We store fiat cash in a physical wallet, and bitcoin works in a similar way, except it's normally digital. Well, to be absolutely accurate, you don't technically store bitcoins anywhere. What you store are the secure digital keys used to access your public bitcoin addresses and sign transactions. This information is stored in a bitcoin wallet. Bitcoin wallets come in a variety of forms. There are five main types of wallet: desktop, mobile, web, paper and hardware. Here’s how they work. If you have already installed the original bitcoin client ( Bitcoin Core ), then you are running a wallet, but may not even know it. In addition to relaying transactions on the network, this software also enables you to create a bitcoin address for sending and receiving the virtual currency, and to store the private key for it. There are other desktop wallets too, all with different features. MultiBit  runs on Windows, Mac OSX, and Linux. Hive is an OS X-based wallet with some unique features, including an app store that connects directly to bitcoin services. Some desktop wallets are tailored for enhanced security: Armory falls into this category. Others focus on anonymity: DarkWallet – uses a lightweight browser plug-in to provide services including coin ‘mixing Continue reading >>

Ethereum Paper Wallet | Beginners Guide

Ethereum Paper Wallet | Beginners Guide

If youve got a significant amount of Ethereum (or any amount for that matter) stored online, I recommend that you transfer it to an offline wallet as soon as you can. Offline wallets, also known as cold wallets, can be as simple as a piece of paper or as complex as a pin protected USB drive . Keeping your Ethereum in a cold wallet keeps it out of the hands of hackers who prey on their victims via the Internet. This security comes at a small cost, though. You still need to transfer your Ethereum to an online wallet or exchange to use it, making your funds less liquid. However, if youre playing the long game and holding for a while, this shouldnt be an issue.

How To Make A Paper Ethereum Wallet

How To Make A Paper Ethereum Wallet

Oliver Dale on November 2, 2017 / 0 Comments It is highly recommended to create an Ethereum paper wallet as one of the safest methods of securing your cryptocurrency. Essentially, an Ether paper wallet is a record of your Ethereum Wallets Private and Public keys which you need to access your wallet and make transactions. Possessing a piece of paper with a code on it and calling it a wallet may come off as a little weird to some. However, it is the safest method you can employ to store your precious Ether coins. Paper wallets provide an extraordinary advantage over other conventional cryptocurrency storage techniques. Imagine the comfort you will feel knowing that your Ether can be stored safely in your house, deposit box, or safe or even buried in your backyard. Advantageously, the paper wallet isnt part of the internet. Therefore, no hacker can ever gain access to your precious cryptocurrencies. A potential thief would have to crack your safe or dig through your whole backyard to find your wallet and cryptocurrency information. A Paper wallet is perfect for people who wish to keep their Ether in cold-storage that is, un-connected from the internet and safely stored away. With a paper wallet the speed for transfers and exchanges, as well as the overall speed at which your Ether becomes available, is greatly reduced. This is due to the coins having to be relayed back to an online wallet before they can be utilized. If you wish to use your Ether at am exchange or for speculation purposes to make some money and benefit from market price fluctuations, then your Ether always has to be readily available. For those purposes, an online wallet is recommended, at least for the sake of efficiency. However, if you plan on sticking with your Ether for the long run by being a Hodler Continue reading >>

Off The Grid Bitcoin and EthereumStorage No matter how improbable the breach of a digital currency exchange is, physically owning some currency is a goodidea. Even with the improved security from folks like Coinbase with offline storage and their vault account type requiring multiple forms of withdrawal verification, it is still wise to diversify how youre storing digital currency the same way its smart to have a portion for an emergency. Coinbase early on made a decision to store the vast majority (98%+) of customer bitcoin entirely offline... Cold storage is storing digital currency offline. A simple method of offline storage has been creating a paper wallet. An image that can be printed onto paper with a Bitcoin or Ethereum wallet consisting of 2 keys. The public key (your wallet address / how other people send currency to you), and the private key (how you send currency). These paper wallets can be physically printed or saved as a file. Companies have developed devices specifically for storing digital currency offline. These hardware devices are the easiest way to store offline, transport, and send / use digital currency for purchases. Devices include KeepKey , Trezor , and Ledger . I didnt go this route because the devices above are only compatible with one or two currencies. I wanted a solution compatible for both Bitcoin and Ethereum, as well as a storage solution not just for digital currency, but for all of my documents, photos, and content. Alternatively, rather than storing everything on a piece of paper or a standalone digital currency hardware device, you can generate a paper wallet, and then store the pdf on an encrypted (password protected) solid state drive (SSD). An SSD is almost as portable as paper, yet more secure, durable, and versatile than a stan Continue reading >>

Unzip it and double-click index.html. This should open MyEtherWallet in your browser. Note: do not move files around in this folder. You need the entire folder for it to work correctly. Enter a strong but easy to remember password. Do not forget it. This encrypts (protects) your private key. It does not generate your private key. This password alone will not be enough to access your Ether. Download your Keystore / UTC file & save this file to a USB drive. This is the encrypted version of your private key. You need the password to access it. It is safer than your unencrypted private key but you must have your password to access it in the future. Read the warning. If you understand it, click the "I understand. Continue" button. Print your paper wallet backup and/or carefully hand-write the private key on a piece of paper. If you are writing it, it is recommend you write it 2 or 3 times. This decreases the chance your messy handwriting will prevent you from accessing your wallet later. Copy & paste your address into a text document somewhere. Get it to your primary, online computer. Use the QR code or a different USB drive. It is best if you do not hand-write it Search your address on . Bookmark this page. This is how you will view your balance at any time Send a small amount of Ether (0.0001 ETH) from an exchange or another wallet to your new offline wallet. On your offline device, unlock your wallet from the Keystore / UTC file on your USB drive or via the private key that you printed out.
