What Does It Mean When Firefox Asks You to Log in Again in All Social Networks

If you lot've ever looked into buying or trading Ethereum and other ERC20 tokens before, then you've probably heard the word MetaMask mentioned. If you lot already know what MetaMask is and how to utilize it, then feel complimentary to skip this article. Just for those of you who have been wondering just what MetaMask is, so this guide was made for you.

What is MetaMask?

If I had to summarize MetaMask in i sentence, information technology would be this. MetaMask is a browser extension that acts equally both a wallet and a style for you to interact with the Ethereum network. That'south why MetaMask comes up a lot when looking into ICOs equally many ICO projects are launched on the Ethereum network and only accept ETH during the ICO.

Allow's interruption that down a piddling more than. The commencement component of MetaMask is a wallet, pregnant that yous can use MetaMask to store your cryptocurrencies. However, every bit MetaMask is specifically for Ethereum, you will only be able to store ETH and ERC-twenty tokens on it. You should know that because MetaMask is connected to the Internet, information technology is defined equally a 'hot wallet'.

The 2nd component of MetaMask is the ability to collaborate with the Ethereum network. What this means is that MetaMask allows you to utilize all the decentralized applications, known every bit dApps, which are hosted on the network. A dApp is chosen as such because its backend lawmaking runs on a decentralized network i.east. Ethereum, unlike a regular app where the backend code is on centralized servers.

Some examples of pop dApps are the game CryptoKitties, casinos such every bit Etheroll, marketplaces such as OpenSea, and decentralized exchanges such as IDEX and ForkDelta. Without the use of a 'bridge' like MetaMask, your browser would not be able to access the Ethereum blockchain unless you lot were running a full Ethereum node (and having to take the entire Ethereum blockchain of over 400GB on your computer). MetaMask does this past injecting a javascript library known as web3.js (written by the core Ethereum team) into your browser'due south page.

MetaMask is also open up source, and if you're interested y'all tin view their code on GitHub here.

Installing and Setting Upward MetaMask

Right now, MetaMask is available on Chrome, FireFox, Opera, and Brave. For the purposes of this guide, I am going to be using the Chrome browser. The links to the MetaMask extensions for all of the above browsers are easily found on the MetaMask homepage.

Once yous install the extension, you lot will run across the MetaMask icon (a trick) announced at the top correct of your screen. Once you click on it, you will encounter the following:

Later clicking Accept on this and the post-obit terms and conditions, you volition be brought to a login interface where you can create your MetaMask account. Note that yous do not need a username, merely a password. MetaMask refers to the password every bit a 'DEN' and it is encrypted and stored within your browser itself (equally opposed to on MetaMask'southward servers).

If y'all're curious as to why the encrypted password is referred to as a DEN, one of the developers explains it in a MetaMask GitHub discussion thread. Personally I idea the reason they did this was since the MetaMask icon is a fox, the countersign would be a den (as in trick'southward den), but that doesn't appear to be the case.

Once yous've created a password, you will be given your unique 12-word seed phrase. These words are used to restore your MetaMask accounts then keep them safe.

Once yous've stored your seed words deeply, you're already all fix!

You tin can also create multiple MetaMask accounts. Each business relationship will accept a unlike address; nonetheless proceed in heed that they are all managed using the aforementioned password and recovery seed words.

Ethereum Main Network vs. Diverse Examination Networks: What's the Difference?

At this point, you might have noticed the 'Main Network' at the top left. MetaMask allows you to switch between the Ethereum main network and (currently) three other test networks.

What's the difference between all of these, you ask? Well, the main Ethereum network is the default selection 1 that yous will demand to utilise for sending/receiving tokens and interacting with dApps. The other 3 are public examination networks; networks which simulate the Ethereum network and the Ethereum Virtual Motorcar.

Test networks are used mainly by developers to test smart contracts without having to pay gas. Text networks tin also exist used to exam different consensus mechanisms altogether. For instance, the Rinkeby examination network uses a Proof of Authority consensus machinery.

That said, well-nigh regular users demand not concern themselves with using Ethereum testnets. Next, allow's take a wait at sending and receiving ETH using MetaMask.

Sending and Receiving Tokens Using MetaMask

While MetaMask can be used for all ERC-20 tokens, I volition be sticking to ETH for the purposes of this review. Since I exercise not currently hold any ETH, but Bitcoin, I volition first have to convert my BTC into ETH. To do this I will exist using ShapeShift.io, an online digital asset exchange platform. Although this is a MetaMask guide, I will also show the main steps of converting BTC into ETH using ShapeShift as it would also be helpful for beginners.

In social club to catechumen my BTC into ETH I just need to provide ShapeShift with my corresponding BTC and ETH wallet addresses. Information technology will and then give me an accost to send my BTC to (too as a recommended mining fee) and will and so send dorsum the requisite ETH to my Ethereum wallet. In this case, my BTC wallet is the CoolWallet Southward, and yous can read my detailed review of said wallet here. The Ethereum wallet will of course exist my MetaMask wallet.

Every bit you can see, my MetaMask wallet is now funded. By my estimation, once I sent my BTC it took about fifteen minutes for ShapeShift to deposit the converted ETH into my MetaMask wallet. Annotation that if you lot click the 'Buy' push above MetaMask volition give you the option of either using CoinBase (US simply) or ShapeShift.

Sending tokens via MetaMask is also very simple. Simply click 'Transport' and primal in the corresponding addresses. Hither, you can run across me sending a bit of ETH back to my CoolWallet Due south.

That'southward information technology! Once the transaction is complete you'll be able to view it every bit follows:

Interacting with dApps Using MetaMask

At present let's wait at the second component of MetaMask, which is interacting with dApps. For many dApps, every bit long as you are logged in to your MetaMask account, yous tin can automatically admission the dApps through your browser.

As an example, take a look at OpenSea, a decentralized market place for crypto collectibles. As you can see, it has already noted my MetaMask wallet address and balance. I did non have to login separately.

Another case is the decentralized casino Etheroll. Again, my MetaMask wallet address and balance is automatically displayed.

How to Reset Your MetaMask Password

So yous diligently took down your seed phrase and stored it safely and not-digitally. However, you were so focused on that attribute that you forgot your login countersign. If that happens, you volition have to employ your 12-word recovery seed phrase to reset your password. It'southward a simple process, however practice keep in mind that while your MetaMask wallets will be restored, whatsoever manually imported wallets will not.

Are There Whatever Fees to Use MetaMask?

The only fee that you volition have to pay is the gas cost, which you take to pay for any transaction on the Ethereum network. So technically, there is no fee to utilize MetaMask, only the Ethereum network. Gas is fee needed to execute whatever transaction on the Ethereum network and is denominated in Gwei which is one billionth of an ETH.

What Kind Of Support Does MetaMask Offer?

Although it is completely costless to utilize, MetaMask does have a dedicated support center which can be found here.

How Safe is MetaMask?

When it comes to cryptocurrencies, security is paramount. Nosotros've all read about the numerous hacks and thefts. And given that cryptocurrencies are still such an unregulated space, there is piffling to no recourse for the victims. If yous want to invest in cryptocurrencies, you lot should always take security at the acme of your listen.

With that being said, there has been no known case of MetaMask being hacked then far. However, this does non mean your MetaMask account cannot be compromised, for example through classic social engineering science methods such as phishing.

Here are simple steps yous can have to protect your MetaMask business relationship:

1. Log out of your MetaMask account when y'all're not using it (when you're logged in your MetaMask account is considered 'unlocked'). Staying logged in to your MetaMask business relationship tin can allow an attacker to view your wallet accost, balances, tokens, and transaction history; information which tin exist used to generate phishing attacks. Ethwalletsecurity shows how this can be done.
2. Spotter out for suspicious popups and notifications when you're logged in every bit this may be a phishing attack. An attacker might generate malicious popups requesting yous to sign for incoming transactions, or notify you that your last transaction failed (and so redirect your transaction to their address). Phony notifications or fake MetaMask interface clones can too be used to attempt to get you to unlock your MetaMask.
3. Don't go on large amounts of cryptocurrencies in your MetaMask wallet. Simply like with any hot wallet, you should use MetaMask for active trading, investing, or purchasing just. The bulk of your cryptocurrencies should be kept in cold wallets such as the Trezor Model T or Ledger.

Conclusion: MetaMask is Convenient and Piece of cake to Employ, merely Precautions Should Ever be Taken

MetaMask is probably the almost convenient and pop style to collaborate with dApps on the Ethereum network at the moment. It is intuitive and easy to utilise and even non-technical people new to crypto should have no problems using it. However, information technology does not come without its risks and you should e'er take precautions when using it (as yous should when information technology comes to everything in cryptocurrencies).
