**What is MetaMask?**
|
||||
MetaMask is a browser extension that allows web applications to interact with the Ethereum blockchain. In our current setup, browsers like Chrome/Firefox display information by fetching it from a database. Our current web browsers (web 2.0 as it’s called) are not build to interface with distributed databases. This is why MetaMask is needed, as it allows modern web browsers to interface with the Ethereum blockchain.
|
||||
|
||||
|
||||
**Why is Metamask required?**
|
||||
The unique part about MetaMask is that it serves a dual purpose as an ERC-20 wallet and a Web 3.0 browser. For users, it works as an Ethereum wallet, allowing them to store and send any ERC-20 tokens. For developers, it allows you to design and run Ethereum DApps right in your browser without running a full Ethereum node. MetaMask talks to the Ethereum blockchain for you.

As the name suggests, a crypto wallet is a type of digital wallet that stores cryptocurrencies. It uses private and public key based encryption to allow users to send and receive cryptocurrencies.
|
||||
|
||||
**Why do we need a wallet?**
|
||||
Unlike traditional pocket wallets, digital wallets do not actually store the currency. For example, your bank app or website does not store the money. It just shows what is recorded on the bank’s servers. The difference for a cryptocurrency is that the record of your transactions are written onto the blockchain, so everyone who is a part of the blockchain has access to these transaction records. A crypto wallet is a software program that interfaces with these various blockchains to show the final recorded amount so the wallet owners can monitor their balance, and send/receive money.

| Desktop or mobile | Can be downloaded and stored on the desktop or mobile device. Can only be accessed through this one device so it's highly secure. Mobile wallets have the additional benefit of being portable | If the computer/phone is hacked or gets a virus, it's possible that your funds could be lost forever. Mobile wallets are also restricted by limited space so tend to be smaller.

| Hardware | The private keys are stored on a physical device such as a USB stick.Hardware wallets have the ability to make transactions online, but are very secure because they are stored offline. | If you lose your hardware wallet, all your funds are lost.

| Software | These are cloud-based wallets that are accessible over the internet. They are the most convenient to access, and are currently the most popular way to store cryptos. | Since online wallets are controlled by third parties, this centralization leads to a greater risk of your private keys being stolen through hacking. | |
