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 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 >>

Why Is There No Good Paper Wallet For Eth As There Is For Btc Or Dash? : Ethereum

See and The Ethereum paper wallets don't seem to have any entropy. Who knows how they generate the keys. Do they just use the same ones over and over again? thanks for the replies. I guess the answer is there is none. There are paper wallets but they seem like crap and I wouldn't trust them: Look, the Javascript for MyEtherWallet paper wallet is all hosted, run from a server. This is not something that you can run with your computer unplugged from the internet. And just look at the source code for the javascript above. It's ridiculous. Compare it with the source code of bitadress.org There's no way that I'm using this wallet, I don't trust it. It's not written in such a way as to be trustworthy. I guess if I want to store something other than Bitcoin, I'll probably try Dash. Or maybe figure out how to do Ethereum cold storage. Continue reading >>

Paper Wallet Guide: How to Protect Your Cryptocurrency Angel Investors, Startups & Blockchain developers... With Bitcoin , Ethereum, and a host of other cryptocurrencies once again making headlines following an incredibly bullish year, crypto security has never been more important, this guide will teach you how to protect your cryptocurrency with a paper wallet and cold storage. Its likely, if youre reading this guide, youve recently decided to buy into this rapidly expanding market, potentially to trade but, most probably, with the intention of holding an amount of a particular currency long term. Weve prepared it to help readers learn how to safely store their cryptocurrencies themselves, in the true trustless spirit of Satoshi Nakamoto himself/herself/themselves. The first, and most important lesson in this guide are: You and you alone are responsible for your cryptocurrencies. A cryptocurrency wallet is a digital wallet that you can use to store, send and receive various cryptocurrencies. The wallet doesnt exactly store your money as a real-world wallet does. Instead, it saves your public and private keys which in turn helps you send and receive money. Lets think of a real world situation before we understand what public and private keys are. Imagine a vending machine. Can anyone and put their money inside the machine right? But, they cant take out the money because they dont have the key, they can only put money in the machine. The only person who can take out the money is the owner of the machine who has the key. In this example, the vending machine is the public address which anyone uses to send money to you. You are the machine owner, and the key that he is carrying is your private key. Using this private key only you can access your money and do what you pleas Continue reading >>

Security - Is There A Way To Generate Ethereum Paper Wallets? - Ethereum Stack Exchange

Security - Is There A Way To Generate Ethereum Paper Wallets? - Ethereum Stack Exchange

Is there a way to generate ethereum paper wallets? Cold storage has been discussed in the past on Ethereum's subreddit . Just to give my 2 cents, on Ubuntu I use the following on the command line: cat ~/.ethereum/keystore/ | qrencode -o qr_image.png Add option -l H to get a code that is easier to decode. The qrencode tool uses the open source libqrencode library, and can be installed using: Once you have the image file, you can then print it off. (Using a wired connection to a printer, unless you're happy with the printer's levels of wireless security.) A command line tool to decode a scanned QR code or image file is included in the zbar-tools package, e.g. zbarimg --quiet qr_image.png The general disclaimer: You'll need to ensure you're happy with piping your keys into someone else's utility... The source code is available, but you'd need to be familiar enough with C to be able to check it isn't taking a copy of the key and then sending it back to the mothership. It should be noted that for this to work you need to generate the keyfiles themselves using geth . Tjaden Hess Jan 20 '16 at 23:26 And it works only with Ubuntu or mint. Maybe a bit too localized. Aren't there any paper wallet generators out there? 5chdn Jan 23 '16 at 13:19 There is a paper wallet generator available at myetherwallet.com . If you don't trust it, you can download it from github and run it offline. There is another paper wallet generator available at ethaddress.org . Printing the private key for ethereum in geth. This is done for creating a real *secure offline paperwallet in your own WM which afterwards stores the money independent from a program *. Based on this posts and another post that points out that the source code of geth can easily be changed to print out the private key. He Continue reading >>

Off The Grid Bitcoin And Ethereum Storage Adam Hurwitz Medium

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 >>

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 >>

However, the basic concepts apply to any other cryptocurrency; for example, litecoin. A bitcoin wallet consists of two keys.
