How to Use MetaMask

If you’re interested in the Ethereum ecosystem, you need an application like MetaMask. Far more than a simple wallet, it allows you to interact with websites that integrate Ethereum.

Why should I bother reading this?

If you’re interested in the Ethereum ecosystem, you need an application like MetaMask. Far more than a simple wallet, it allows you to interact with websites that integrate Ethereum.

MetaMask will let you connect to decentralized applications from inside your browser (or through a mobile app). You can make trades without intermediaries and play games with fully-transparent code (so you know you aren’t being cheated).

Check out the guide below to get started!

Introduction

With Ethereum came the promise of a distributed Internet – the long-awaited Web 3.0. A level playing field characterized by a lack of central points of failure, true ownership of data, and decentralized applications (or DApps).

Such an infrastructure is steadily coming together with an industry-wide focus on Decentralized Finance (DeFi) and interoperability protocols that aim to bridge the various blockchains. It’s now possible to trustlessly exchange tokens and cryptocurrencies, take out crypto-backed loans, and even use Bitcoin on Ethereum.

For many Ethereum enthusiasts, MetaMask is the go-to wallet. Unlike your regular smartphone or desktop software, it comes packaged as a browser extension, allowing users to directly interact with supporting webpages. In this article, we’ll explain how MetaMask works and walk you through getting started with it yourself.

What is MetaMask?

MetaMask is an open-source Ethereum wallet that supports all kinds of Ethereum-based tokens (such as those following the ERC-20 standard, or non-fungible tokens). On top of that, you can receive them from others, or purchase/swap them with the built-in Coinbase and ShapeShift integrations.

What makes MetaMask so interesting is that it can interface with websites. With other wallets, you’d need to copy-paste payment addresses or scan a QR code on a separate device. With the MetaMask extension, the website simply pings your wallet, and you’re prompted to accept or reject the transaction.

MetaMask can serve as a regular crypto wallet, but its real strength is in seamlessly interfacing with smart contracts and decentralized applications. Let’s now look at how to set it up.

Install MetaMask

The MetaMask wallet can be installed on Google Chrome, Firefox, or the Brave Browser. It’s also available on iOS and Android, but we won’t cover that in too much depth. We’re going to use Firefox throughout this tutorial, but your steps will be more or less identical, irrespective of the platform you’re using.

Head over to the official download page on metamask.io. Select your browser, which will take you to the Chrome web store or the Firefox add-ons site. Click on the button to add the extension to your platform. You may need to grant it some permissions before it’s up and running. Make sure you’re happy with the level of access it has to your browser – if you are, we’re good to go.

Initialize the wallet

You should now see a welcome message.

Metamask intro screen If you’re anything like us, you’ll probably spend a good bit of time trying to make this guy dizzy with your cursor.

Once you’re done pestering the fox on the welcome page, click on Get Started. This is where you’ll be prompted to either import a seed phrase or create a new one. Click on Create a Wallet. The next page asks whether you want to submit anonymized data to help the devs improve the app. Pick whichever option you prefer.

Now we need to create a password. If you’re one of those legendary creatures that actually reads the user agreement for your software, you can view it by clicking on Terms of Use. Otherwise, come up with a strong password, tick the box, and hit Create.

Back up your seed words!

The following point is enough to warrant its own subheading. MetaMask is a non-custodial service, meaning that no one else can access your funds – not even the MetaMask developers. Your tokens exist in a sort of encrypted vault within your browser, protected by your password. That means that if your computer is lost, stolen, or destroyed, nobody can help you recover the wallet. Your private keys will be forever lost in the void of cyberspace.

So, it’s crucial that you write down your backup phrase. This is the only way you can restore your account should something unfortunate happen. As suggested, we recommend that you write the words down and store them in two or three different locations. You don’t need to bury them in a fireproof safe deep in the forest, but hey, it can’t hurt.

Click on the grey box to reveal the phrase. Click on the grey box to reveal the phrase.

When you get to the next page, the program anticipates that you may have been lazy with the previous step, because it asks you to confirm the phrase. If you didn’t the first time, click Back and write it down!

Confirm the phrase, then proceed to the next step. Hit All Done, and you’ll see the wallet interface.

The boring part’s over, let’s get rich on (testnet) ether next.

Fund the wallet

In this tutorial, we’re going to be using the Ropsten testnet. It’s a network that functions almost exactly like the real Ethereum network, but its units have no value. These come in handy when you’re developing contracts and want to make sure that they don’t have vulnerabilities that allow attackers to drain $50m in value. Every step we perform on this network today will be replicable on the real thing (except for the part where they gift us free ether, unfortunately).

To tune into the Ropsten testnet, click on Main Ethereum Network in the top right corner and select Ropsten Test Network.

Ropsten test network There are lots of different testnets on Ethereum. If you’re wondering about the differences, check out this comparison.

We’re going to use a faucet to get some fake money to play with. Click on RopstenETH for receiving (in the image below):

Ropsten testnet

Then click Buy:

Ropsten testnet

Get Ether in front of the Test Faucet:

Ropsten testnet

You will be taken to this page. Click request 1 ether from fauset and wait for 1 ether to arrive at your address.

Usually, Ethereum transactions are confirmed fairly quickly, but it may take some time before 1 ETH reaches your wallet. You can check the receipt of assets by clicking on RopstenETH in the list of Ropsten network tokens.

As soon as the funds are transferred, we can start working with DApps.

How to add another network to Metamask

All networks are added according to one algorithm:

  • expand the wallet (this is for convenience, you can skip it);
  • click on the drop-down list of networks and select add network;
  • enter the network parameters and save it.

Ropsten testnet

To add a network, you need the following information:

  • “Network name” – how the network will be called in your wallet;
  • “New RPC URL” – blockchain address, some blockchains may have more than one.
  • “Chain ID” – numbers that are different for all blockchains;
  • "Currency symbol" - designation of the main token of the network;
  • "Block explorer URL" - site address for browsing transactions and wallets on the network.

After filling and saving, the added network will appear in the drop-down list.

Ethereum Testnets in Metamask

How to add the Rinkeby network, the Kovan network and other test networks to Metamask, only the Ethereum Mainnet network is displayed in the wallet by default - this is the main blockchain network, but there are several more besides it, namely:

  • Ropsten Ethereum network;
  • Rinkeby Ethereum network;
  • Goerli Ethereum network;
  • Kovan Ethereum network.

In order to use these networks, you just need to enable their display in the wallet settings.

Ropsten testnet

Ropsten testnet

To do this, go to the wallet settings, then go to the additional settings, scroll to the “Show test networks” item and turn the switch to the “on” position.

Networks that do not work in Metamask

Metamask was originally developed for the Ethereum network, but it also supports other "ether-like" blockchains compatible with the EVM (Ethereum Virtual Machine). Below is a list of networks that do not work in Metamask.

Tron Network (TRX) and TRC20 tokens in Metamask

Despite the fact that the Tron network is almost a complete copy of Ethereum, Tron does not support EVM, which means it cannot be added to Metamask. Accordingly, Metamask does not support TRX coins and all TRC20 standard tokens. But at the same time, you can add the TRX token issued on the BSC network to the metamask, the address of the smart contract is here.

Solana network (SOL) is not supported in Metamask

The SOL coin has its own native blockchain - Solana, it is not compatible with the EVM and is not supported by Metamask, but just like in the case of TRX, you can add SOL (Wrapped Solana) tokens issued in the Ethereum, BSC and Polygon networks to Metamask, addresses all smart contracts here.

Terra network (LUNA) cannot be added to Metamask

Terra is a separate blockchain with its own native coin LUNA, this network is not supported by Metamask. You can add LUNA tokens issued in other blockchains - Ethereum, BSC and Polygon, smart contract addresses here.

Access to decentralized network

Because we're on the testnet, we don't have as many apps to choose from to interact with.

We will use DApp Uniswap. Uniswap – это децентрализованная биржа (DEX), на которой можно размещать сделки, не полагаясь на посредников. Механизмы, лежащие в ее основе, довольно изящны.

You can access Uniswap here. In the top right-hand corner, you should see a prompt to Connect to a wallet. You’ll see this in some form on all MetaMask-compatible sites, as it doesn’t automatically connect for security reasons. Click on it, and you’ll be asked to select which wallet you’re using. In case you haven’t been following, that wallet will be MetaMask.

When a site first attempts to connect, a MetaMask dialog will appear, asking you to confirm the action. You’ll be able to select an account (we only have one, for now, so leave that as is) before verifying what permissions you’re about to grant. In this case, as in many others, the site is requesting information on the wallet address your account controls.

On MetaMask and privacy

It’s important to be mindful of what you’re permitting. If a website knows your address, they can see all of the ether and token transactions to and from it. What’s more, they can correlate it with your IP address.

Some prefer to segregate their addresses to prevent any overlap, while others aren’t concerned with these risks (after all, the blockchain is public). The level of privacy you want to achieve ultimately depends on you. As a general rule, don’t grant access to websites you don’t trust.

Swapping ether for DAI

Time to make our first swap. We’ll be doing it for DAI, an ERC-20 token that serves as a stablecoin. Just like our ether, though, this DAI has no real-world value. Hit Select a token, add the Uniswap Default List, and then click on DAI. Alternatively, you could also pick WETH (wrapped ether).

All that’s left to do is to input the amount of ETH we want to swap. As we do that, we’ll get an estimate of how much DAI we’ll receive. And we’re good to go! Hit Swap.

*Complete the swap with MetaMask.*

You’re once again prompted to take action in MetaMask. In this case, you need to okay the transaction before it’s created. Make sure you’re happy with the fees when you’re doing this on the mainnet, as they can be significant.

After that, we just need to wait for the transaction to confirm!

Where are my tokens?

So, your ether is gone, but new tokens are not displayed in your account. Don't panic - you need to add them manually. In other words, in the Ropsten network (as in any blockchain network) you have one public address to which you transfer the actual ether itself, or tokens from this network. But in order to display the token in the Metamask wallet, you need to add the contract address of this token.

For more popular tokens, you can select Add Token in your wallet and search for the name or ticker. For the less popular ones (or those on the testnet), we need to add the contract address – an identifier that tells MetaMask where to look for our balance.

  • Open your wallet by clicking on the extension.
  • Click on the three dots in the top bar.
  • Select View on Etherscan.
  • Under Overview, click on the Token dropdown and select DAI.
  • Under Profile Summary, you should see a contract address. Hover over it and copy the address.
  • Return to MetaMask and click on Add Token.
  • Click on the Custom Token tab.
  • Paste what you’ve just copied into the Token Contract Address form.
  • The rest should autofill. Click on Next, followed by Add Tokens.
  • Return to the main overview to see your full balance.

Congrats! You’ve just interacted with your first DApp by trustlessly swapping ether for DAI. Everything you’ve learned can now be done in the real world. When you’re ready to play with mainnet applications, remember to switch back from Ropsten to the main network.

What else should I know?

MetaMask has some other neat features that we haven’t covered today. You can also connect a hardware wallet (Trezor and Ledger are both supported), create a contact list, and, of course, receive and send funds as you would in a normal wallet. Check out the settings to customize the extension to suit your needs.

Other than that, the usual security principles apply: MetaMask is a hot wallet, meaning that it runs on an internet-connected device. This exposes you to more risk than a cold wallet, which is kept offline to reduce attack vectors.

Lastly, when using MetaMask, it stands to reason that you should be conscious of what websites you’re granting access to.

The MetaMask app

The MetaMask Android/iPhone app provides a neat solution for interfacing with Web3 apps on the go. Boasting much of the same functionality as the extension, it integrates a DApp browser so you can access various decentralized applications at the touch of a button.

The MetaMask app’s browser. The MetaMask app’s browser.

The workflow of the application is very similar to that of the browser extension. You can make direct transfers of ether or tokens from your wallet, or even interact with Uniswap as we saw above.

Closing thoughts

MetaMask is a powerful tool for browsing the decentralized web. If you’ve followed along with the steps in this guide, then you’ve seen the wallet’s potential. Evidently, others have, too: it currently boasts over ten millions users.

As the Ethereum stack develops, applications like MetaMask will undoubtedly become integral components in the bridge between existing technologies and nascent cryptocurrency infrastructure.

Market Makers and Market Takers Explained

Market Makers and Market Takers Explained
Markets are made up of makers and takers. The makers create buying or selling orders that aren’t carried out immediately (e.g., “sell BTC when the price hits $15k”). This creates liquidity, meaning it’s easier for others to instantly buy or sell BTC when the condition is met. The people that buy or sell instantly are called takers. In other words, the takers fill the orders created by the makers.

The Wyckoff Method Explained

The Wyckoff Method Explained
Данный торговый метод был разработан Ричардом Вайкоффом в начале 1930-х годов. Он состоит из ряда принципов и стратегий, изначально разработанных для трейдеров и инвесторов. Вайкофф посвятил значительную часть своего жизненного опыта для изучения поведений на рынке, и его работа до сих пор оказывает влияние на большую часть современного технического анализа (ТА). В настоящее время, метод Вайкоффа применяется ко всем видам финансовых рынков, хотя изначально он был ориентирован только на акции.

Об инвестировании, хаосе и аппроксимации рынка

Об инвестировании, хаосе и аппроксимации рынка
Данную статью я решил написать, потому что мне часто пишут в личных сообщениях с вопросами, насколько профессиональна ваша команда управляющих? Владеете ли вы инсайдерской информацией при торговле? Как поведет себя портфель на падающем рынке? и так далее. Ниже я постараюсь прояснить стратегии, и кратко объяснить почему они работают. На просторах Сети полным полно торговых стратегий, материалов, мануалов, готовых решений, сборок, обученных нейросетей и прочего добра, посвященного прогнозированию цен на криптовалютные и традиционные биржевые активы, пахнущего быстрыми и легкими доходами с минимумом усилий. И хоть пишут их разные люди, с разными подходами, на разных платформах и с разными парадигмами, у них всех есть один неизменный общий атрибут — они не работают. Другими словами с их помощью невозможно со стопроцентной вероятностью спрогнозировать куда пойдет график в том или ином отрезке времени в будущем.

What Is Livepeer (LPT)?

What Is Livepeer (LPT)?
Livepeer is a decentralized video protocol built on the Ethereum blockchain. It was designed for anyone to seamlessly integrate video content into applications in a decentralized manner and at a fraction of the cost of traditional solutions. Decentralization of video processing is accomplished by distributing the transcoding process to a network of node operators. Transcoding is an essential step in ensuring smooth delivery of video content to end users. It involves taking raw video files and converting them to the optimal state for each end user, based on factors such as device screen size or internet connection.

Coin Mixing and CoinJoins Explained

Coin Mixing and CoinJoins Explained
Bitcoin is often referred to as digital cash, but this is a questionable comparison. If Alice pays Bob ten dollars in cash, Bob has no idea where the money came from. If he later goes on to give it to Carol, she will be unable to deduce that Alice was once in possession of it. Bitcoin is different because of its inherent public nature. The history of a given coin (more precisely, an unspent transaction output or UTXO) can be trivially observed by anyone. It’s a bit like writing the transaction amount and names of participants on a bill every time it’s used.

What Is Anti-Money Laundering (AML)?

What Is Anti-Money Laundering (AML)?
AML regulations attempt to stop the illegal laundering of illicit funds. Individual governments and multinational organizations like the FATF legislate against money laundering activities. Money laundering takes “dirty” money and turns it into clean money. This can be done by disguising the origins of the funds, mixing them with legitimate transactions, or investing them into legal assets.

What Are Crypto Cards and How Do They Work?

What Are Crypto Cards and How Do They Work?
A typical crypto card lets you earn crypto rewards or instantly convert your crypto to fiat currency to pay for goods and services. Both Mastercard and Visa issue crypto cards, meaning you can use your crypto in millions of locations globally. A prepaid crypto card is similar to a debit card in that it has to be pre-loaded with crypto to spend. You can get a crypto card from a licensed issuer such as a crypto exchange or bank. However, crypto cards aren't without risk. Your funds stored on the card can still lose their market value, and any transactions you make with your card are likely to be taxable.

What Is Play-to-Earn and How to Cash Out?

What Is Play-to-Earn and How to Cash Out?
Play-to-earn games allow users to farm or collect crypto and NFTs that can be sold on the market. By playing the game regularly, each player can earn more items or tokens to sell and generate an income. Some players have even begun to supplement or replace their salaries playing these blockchain games. However, such activity involves risk, as you typically need to put up an initial investment to purchase characters and items to play the game. Blockchain helps guarantee the collectibility of these items and create working digital economies. Blockchain technology and NFTs allowed for the creation of digital items that are impossible to duplicate. This created the concept of digital scarcity.

What Is Uniswap and How Does It Work?
Uniswap is a set of computer programs that run on the Ethereum blockchain and allow for decentralized token swaps. It works with the help of unicorns (as illustrated by their logo). Traders can exchange Ethereum tokens on Uniswap without having to trust anyone with their funds. Meanwhile, anyone can lend their crypto to special reserves called liquidity pools. In exchange for providing money to these pools, they earn fees. How do these magical unicorns convert one token to the other? What do you need to use Uniswap? Let’s read on.

Mining Pools Explained

Mining Pools Explained
Mining is integral to the security of Proof of Work blockchains. By computing hashes with certain properties, participants are able to secure cryptocurrency networks without the need for a central authority. When Bitcoin first launched in 2009, anyone with a regular PC could compete with other miners to guess a valid hash for the next block. That’s because the mining difficulty was low. There wasn’t much hash rate on the network. As such, you didn’t need specialized hardware to add new blocks to the blockchain.

Who Is Satoshi Nakamoto?
Satoshi Nakamoto is the pseudonym behind the development of Bitcoin and the authorship of the original Bitcoin whitepaper. The question “who is Satoshi Nakamoto?” has led to speculation of their true identity as well as people falsely claiming they are Satoshi Nakamoto. The creator of Bitcoin has been clouded in mystery for more than a decade. However, it’s clear that Satoshi still owns bitcoins since their public keys were traced from the genesis block, which Satoshi mined.

Delegated Proof of Stake Explained

Delegated Proof of Stake Explained
The Delegated Proof of Stake (DPoS) consensus algorithm is considered by many as a more efficient and democratic version of the preceding PoS mechanism. Both PoS and DPoS are used as an alternative to the Proof of Work consensus algorithm, since a PoW system requires, by design, lots of external resources. The Proof of Work algorithm makes use of a large amount of computational work in order to secure an immutable, decentralized and transparent distributed ledger. Contrarily, PoS and DPoS require fewer resources and are, by design, more sustainable and eco-friendly. To understand how Delegated Proof of Stake works, one must first grasp the basics of the Proof of Work and Proof of Stake algorithms that preceded it.

What Is a DoS Attack?

What Is a DoS Attack?
In short, a DoS attack (or Denial-of-Service attack) is a method used to disrupt legitimate users' access to a target network or web resource. Typically, this is accomplished by overloading the target (often a web server) with a massive amount of traffic - or by sending malicious requests that cause the target resource to malfunction or crash entirely.

What Is a 51% Attack?
Before diving into the 51% attack, it is crucial to have a good understanding of mining and blockchain-based systems. One of the key strengths of Bitcoin and its underlying blockchain technology is the distributed nature of building and verifying data. The decentralized work of the nodes ensures that the protocol rules are being followed and that all network participants agree on the current state of the blockchain. This means that the majority of nodes need to regularly reach consensus in regards to the process of mining, to the version of the software being used, to the validity of transactions, and so forth.

Delayed Proof of Work Explained

Delayed Proof of Work Explained
Delayed Proof of Work (dPoW) is a security mechanism designed by the Komodo project. It is basically a modified version of the Proof of Work (PoW) consensus algorithm that makes use of Bitcoin blockchain’s hashpower as a way to enhance network security. By using dPoW, Komodo developers are able to secure not only their own network but also any third-party chain that ends up joining the Komodo ecosystem in the future. In fact, dPoW can be implemented for any project that develops an independent blockchain using a UTXO model.

What Is a Blockchain Consensus Algorithm?

What Is a Blockchain Consensus Algorithm?
A consensus algorithm is a mechanism that allows users or machines to coordinate in a distributed setting. It needs to ensure that all agents in the system can agree on a single source of truth, even if some agents fail. In other words, the system must be fault-tolerant (see also - Byzantine Fault Tolerance Explained). In a centralized setup, a single entity has power over the system. In most cases, they can make changes as they please – there isn’t some complex governance system for reaching consensus amongst many administrators.

Pyramid and Ponzi Schemes
Most individuals that invest in Bitcoin – or that participate in Initial Coin Offering (ICO) events – are usually concerned about two things. First, the Return of Investment (ROI), which represents the profits they will eventually make from the initial investment. Then, there is a second concern, which is related to the amount of risk involved with the investment. When the risks are too high, investors are more likely to lose their initial investment (in parts or completely), which would result in a negative ROI.
