What Does MetaMask Do?
At the highest level, MetaMask equips you with all the tools required to:
- Generate and securely manage your blockchain account credentials (public/private key pairs)
- Store, send, and receive ETH and ERC-20 tokens
- Interact with censorship-resistant, decentralized applications (dApps) built on Ethereum
- Access a parallel financial system called DeFi featuring lending, trading, betting and more
But most importantly, it abstracts away the complexity associated with this futuristic internet of value – no coding required.
Instead, MetaMask elegantly handles everything under the hood and presents a clean user interface familiar to anyone who has used a traditional web browser and wallet before.
Behind its ease of use, MetaMask is actually bridging between the aging financial framework built for a Web2 world with the emerging, decentralized architecture of Web3.
It essentially serves as your passport into this parallel universe of permissionless innovation.
Before MetaMask arrived in 2016, accessing dapps and DeFi markets required command line interfaces and coding know-how.
The usability hurdles deterred mainstream users while hampering developer momentum and ecosystem growth.
MetaMask changed the game by offering the first widely accessible portal through this threshold for the average crypto enthusiast. And one that balanced rich functionality with radical simplicity.
The proof is in the numbers…
MetaMask by the Numbers
Since launching, MetaMask adoption has soared exponentially:
- From 0 users initially to 21+ million monthly active users today
- Processing over $7 billion in monthly transactions
- Supporting 3000+ decentralized applications
- With over $3 billion in digital assets secured
Beyond sheer user growth, MetaMask has:
- Become the #1 most popular crypto wallet extension on Chrome, Firefox, Brave and Edge
- Accounts for nearly 50% market share of wallets interacting with Ethereum-based decentralized apps and services
- Powers over 85% of NFT marketplace transactions on platforms like OpenSea
Third-party data site DappRadar also confirms that MetaMask drives usage for 8 of the top 10 DeFi protocols.
Dominance across dApps and DeFi validates why MetaMask is so critically important to the mainstream adoption of Ethereum and the broader crypto ecosystem.
According to DeFi thought leader and Coinbase co-founder Fred Ehrsam:
"MetaMask is the key to unlocking the next generation of financial applications powered by decentralization and crypto economics. Its simplicity, elegance, and focus has made it the standard gateway to accessing Web3 services."
For context, Web 3.0 refers to the next evolution of internet services and applications – one based on decentralization, blockchain technology, transparency, greater user control over data/identity, and elimination of corporate and government middlemen from processes.
And MetaMask serves as the most popular easy button bridging web2 and web3.
Why MetaMask Matters
Before decentralized networks like Bitcoin and Ethereum, individuals needed to rely on influential intermediaries like banks, tech giants, media platforms and government bodies to access essential financial, communication and informational services.
Unfortunately, time and again giant corporations and institutions have breached public trust through unreliability, security failures, censorship, misuse of user data, biased manipulation or outright denial of service.
These systemic risks introduced by central points of control and third party dependency have eroded freedom and sovereignty on an unprecedented societal level.
The invention of cryptocurrency and blockchain networks established a foundation for peer-to-peer, decentralized alternatives to these traditionally centralized systems.
Solutions that align better with core values like fault tolerance, permissionless access, transparency, user control, and censorship resistance.
Ethereum expanded on Bitcoin‘s vision as a decentralized financial system by allowing developers to build entire applications on top of its global computing infrastructure – from games to social networks to prediction markets and beyond.
But to make these blockchain powered-applications usable for the everyday internet user required simplifying the intimidating technical barriers to entry.
MetaMask elegantly stripped these barriers down to just a few clicks so anyone can now access this parallel universe called Web3.
And participate in or directly build its alternative, decentralized infrastructure for finance, culture and identity in just minutes.
No advanced coding skills or command line knowledge necessary anymore.
That‘s why for the future of freedom, open access and innovation, MetaMask has become the passport for billions of people to transcend the limitations and risks of legacy frameworks.
Now let‘s get you set up with this pivotal gateway to Web3…
Installing the MetaMask Browser Extension
MetaMask supports Google Chrome, Mozilla Firefox, Brave Browser and Microsoft Edge via installable browser extensions.
We‘ll use Google Chrome in this example.
To install MetaMask:
- Open the Chrome Web Store
- Search for “MetaMask”
- Click “Add to Chrome”
- Accept the permissions prompt to finalize install
This will install MetaMask conveniently in your extensions bar for easy access.
Creating Your MetaMask Wallet
Once installed, it’s time to create your wallet…
- Click the MetaMask logo to open the extension
- Click “Get Started”
- Read and Accept the Terms of Use
- You’ll see a “Secret Backup Phrase” – This 12 word phrase gives you access to your funds if you lose your password. Store it secretly offline for safety.
- Click “Next”
- Confirm your Secret Backup Phrase
- Set a Password – Make it long, random and secure
- Click "All Done"
Boom! Your MetaMask wallet setup is complete.
You’ll see “Account 1” – this represents your public wallet address used to transact and interact with the Ethereum blockchain.
Think of this like your account number and routing number when sending money from your traditional bank account.
Behind the scenes, MetaMask has also generated encrypted private keys uniquely tied to your wallet and funds. Never share these keys!
Now, let’s add crypto to your wallet…
Buying ETH on MetaMask
While you can transfer Ethereum in from an external source, the easiest way to get started is buying ETH directly on MetaMask.
MetaMask offers convenient fiat on-ramps to purchase crypto with a credit card or Apple Pay through partners like Wyre and Transak.
To buy ETH with your debit/credit card:
- Open your MetaMask browser extension wallet
- Click “Buy”
- Choose your desired currency
- Select desired payment method
- Specify purchase amount
- Provide billing details
- Click Next
- Preview details carefully (fees, receive amount, limits)
- Confirm purchase!
Once the transaction is completed on-chain, the ETH will show up right in your MetaMask wallet. Nice!
Now you have funds to transact with…
Next let’s walk through sending, receiving and storing Ethereum.
Sending and Receiving Ethereum Transactions
Thanks to blockchain technology, sending value peer-to-peer is as simple as sharing a document.
To receive ETH (or tokens)…
All the sender needs is your public address.
Retrieving this is simple:
- Click your Account icon
- Click “My Accounts”
- Select desired account
- Click more options (…)
- Click “Copy Address”
Then provide the sender your address to enable deposits into your wallet.
Conversely, to send ETH (or other ERC-20 tokens) to someone else:
- Inside MetaMask, select “Send”
- Paste the recipient‘s public address
- Input the transfer amount
- Click Next
- Adjust the Gas Fee (Higher = Faster) or keep default
- triple check address and amount
- Confirm transfer
Once the transaction is verified on the Ethereum blockchain, the transfer will complete right in your activity tab.
So now you know the basics of sending and receiving value!
Keeping Your Crypto Safe
MetaMask prioritizes usability and user experience to accelerate adoption by abstracting away blockchain complexities.
But with accessibility comes heightened responsibility around security best practices – aka Avoiding stupid losses!
Here are critical safety tips for every MetaMask user:
🔑 Secret Backup Phrase: Guard this 12 word master key that unlocks your wallet like a hawk. Store it securely offline.
🔒 Strong Password: Use a randomly generated 20+ character password. Include numbers, letters uppercase, symbols.
🛡️ Enable 2FA: For valuable accounts, add Google Authenticator or Authy for 2-factor authentication.
⏰ Timed Auto Lock: Set an auto logout timer for when you walk away. Every minute counts to defend from physical compromise.
🌐 Dedicated Browser: Use a separate, clean browser profile just for crypto activity to limit exposure from various web threats.
🔨 Notifications: Turn on notifications inside MetaMask to stay on top of every transaction. Monitoring activity helps identify misuse immediately.
No vault is completely impenetrable. But combining the above security foundations significantly reduces your risk profile and guards against unauthorized access.
For advanced HODLers securing serious capital, MetaMask + hardware wallet integration offers the highest security standard via cold storage.
Ledger and Trezor leverage state-of-the-art cryptographic safeguards and offline asset protection for maximum upside guarantees without the usability tradeoffs.
But don‘t let the basics above overwhelm you initially. Start by nailing down good password hygiene, 2FA, and mastering your Secret Recovery Phrase storage. The rest you can evolve over time as your investment grows.
Now let‘s jump into some of what makes MetaMask extra useful…interacting with dApps and DeFi protocols!
Connecting to Decentralized Apps
Beyond basic sending and receiving of funds, thousands of decentralized apps (dApps) are emerging that expand what you can do peer-to-peer.
For example:
- Lending & Saving – earn interest on your crypto assets
- Trading & Investing – swap tokens, invest in indexes
- NFT Marketplaces – create, mint, auction digital art/collectibles
- Games – play-to-earn, crypto gaming networks
- And so much more…
But to access and use these dApps in a secure, private way you need to connect your wallet rather than creating endless individual accounts.
This is where MetaMask shines.
When visiting a dApp for the first time, you‘ll be prompted to connect your wallet.
- Click “Connect Wallet”
- Select MetaMask
- Your public wallet address will be shared with the site to enable live interactions
That‘s it! This safely connects the dApp to your wallet to power transactions without ever revealing sensitive keys.
From basics like Uniswap…to emerging platforms like Hop Protocol for social tokenization…to even radical experiments like Proof of Humanity establishing universal basic income…the possibilities are endless!
As the gateway to the open metaverse, MetaMask unlocks it all.
