    How to Use an Ethereum Wallet

    Leslie Toh June 20, 2018 - Posted by Leslie Toh on Guides

    A cryptocurrency wallet is a software to securely store your cryptocurrency and send cryptocurrency to another person. It functions as a bank account which can store currency and also receive and remit the currency. An Ethereum wallet allows the user to store, send and receive any ERC20 tokens on the Ethereum blockchain.

    For those who are not familiar with crypto wallets or have never come across a digital wallet, this guide will show you how to use an Ethereum Wallet and MyEtherWallet.

    Types of Ethereum Wallets

    Wallets are categorized into hardware and software wallets. Hardware wallets are designed to store wallet information in a USB device and are protected by encryption on the device. But in order to access the functions, the hardware wallet needs to be plugged into a computer. Software wallets reside and store wallet information on the computer. Once it connects and downloads the blockchain data, the wallet can then have access to the updated transaction records.  Below are some examples of hardware and software wallets.

    1. Ledger Nano S

    Adding an ERC20 Token to Your Wallet

    There are a bunch of tokens in the market that are running on the Ethereum blockchain. In order for your wallet to recognise the type of ERC20 token you want to add, you need to input the following variables to your wallet:

    1. Contract address
    2. Token Name
    3. Symbol
    4. Decimal

    To find out about the token information:

    3. Click into the token

    In your Ethereum wallet, click contracts -> Custom Tokens -> Watch Tokens. Then key in all the details. Assuming we are adding Token EOS (EOS):

    When you click okay, the coin will appear in contracts -> custom tokens.

    MyEtherWallet Introduction

    MyEtherWallet is a free open source tool for anyone to create an ether wallet. The wallet does the same function as the Ethereum Wallet but does not take up so much space in your computer.

    MyEtherWallet allows the entire blockchain to be stored on its servers so that user does not need to download the entire blockchain.
