Cryptocurrency is virtual money and as such, it cannot be stored under similar storage conditions as conventional money, this necessitated the creation of a storage system unique to cryptocurrency, this storage system is called a wallet.

A cryptocurrency wallet is fundamentally a storage system for cryptocurrency with the necessary tools to support withdrawals and deposits of funds, just like a regular bank account. A typical cryptocurrency wallet comprises two components – the public key and the private key.

The public key is like a bank account number to the wallet. It is available to all users on the network and every transaction that involves sending funds to another user is completed using the recipient’s public key.

The private key on the other hand is more like a secret password that authenticates a user and grants them access to the funds in their wallet. The user is expected to keep the private key confidential and secured. If the private key is compromised, then the funds in the wallet associated with that private key are vulnerable to theft. Fundamentally, a user receives funds from others through the public key and sends money to other users via the private key.

There are 5 main types of wallet; web wallets, desktop wallets, mobile wallets, paper wallets and hardware wallets. Each type of wallet is however not without its own complexities, benefits and drawbacks. This article will focus on a web-based wallet known as MyEtherWallet.

 

What is MyEtherWallet (MEW)?

MyEtherWallet is a type of web-based wallet for storing and managing cryptocurrency. It is often abbreviated to MEW. MyEtherWallet provides a free, open source and user friendly interface for managing Ethereum and other ERC-20 compliant tokens. Like other web based wallets, MEW can be accessed from any browser - Firefox, Chrome, Internet Explorer etc., however, unlike several other web browsers, the wallet is not hosted on a server. 

One of the major disadvantages of web wallets is the fact that the private keys are hosted on a server by a third party and beyond the control of the user. If the site hacked or closed down, assets and holdings in that particular wallet are automatically lost to the user. MyEtherWallet, however does not function like a conventional web based wallet. Here, the browser is used to generate the required data and nothing is stored on the server. In effect MEW can neither hold keys, recover keys, access accounts, reset passwords, nor reverse transactions.

MyEtherWallet can hold Ethereum and ERC-20 tokens (tokens are based on the Ethereum blockchain). Putting into consideration the fact that several of the new cryptocurrencies now springing up are ERC-20 compliant and accept Ethereum as a means of payment in their ICOs (Initial Coin Offering), getting an Ethereum compatible wallet is virtually a necessity. MyEtherWallet remains the most efficient Ethereum based wallet and below is a step by step guide on how to step up a MEW wallet.
