MetaMask is one of the most commonly used crypto wallets. It allows users to send, receive, and keep Ethereum-based tokens. It also allows users to connect their normal web browsers to the Ethereum blockchain and interact with decentralized applications without hassle.
MetaMask is non-custodial, unlike centralized wallets, so you can directly control your private keys and, thus, gain additional security. The wallet can be accessed via browser extensions (Chrome, Firefox, Edge, and Brave) and mobile apps (iOS and Android).
Understanding MetaMask
MetaMask is a crypto wallet that works with the Ethereum blockchain and other EVM-compatible networks. It can be used to securely hold Ether (ETH) and ERC-20 tokens, manage multiple wallets, and sign blockchain transactions.
Users also use MetaMask to log into dApps, use DeFi (decentralized finance) apps, and buy and sell NFTs in marketplaces such as OpenSea.
How Does MetaMask Work?
Secure Private Key Storage: In contrast to centralized wallets that store private keys on servers, MetaMask encrypts and locally stores them on your device.
Web3 Integration: MetaMask allows blockchain integrations and interactions between the wallet and webpages by inserting a JavaScript library called Web3.js into every page you visit.
Transaction Processing: Users can issue transactions in MetaMask and set gas prices to have them executed quicker or cheaper.
Key Features of MetaMask
Create a Wallet in a Few Steps: Users can create their wallets protected by a 12-word Secret Recovery Phrase.
Multi-Chain Support: MetaMask is technically an Ethereum wallet by design but can be configured to support Binance Smart Chain (BSC), Polygon, Avalanche, and other EVM-compatible networks.
Seamless dApp Integration: MetaMask is accepted by many NFT markets, DeFi platforms, and Web3 apps.
Custom Token Support: Users can now manually add custom ERC-20 and ERC-721 tokens to their wallet.
Security and Privacy: MetaMask does not have user data at its disposal, allowing users to have full control of their funds.
Getting Started with MetaMask
How to Install MetaMask?
Visit the Official Website: Navigate to MetaMask.io and choose the version you need for either your browser or your mobile device.
Download and Install: Add MetaMask as a Chrome, Firefox, Edge, or Brave browser extension. Alternatively, you can get the MetaMask Mobile App on iOS or Android.
Create a Wallet: Select “Create a Wallet” and create a strong password to protect your account.
Configuring Your MetaMask Wallet
Secure the Secret Recovery Phrase: MetaMask will generate a Secret Recovery Phrase of 12 words, which is the only way to restore your wallet once it has been created. If you forget your password or lose access, this is the only way to regain access.
Note: Keep this phrase in a safe place offline, and do not share it with anyone.
Confirm the Recovery Phrase: MetaMask will prompt you to re-enter the recovery phrase in the exact order to confirm that it’s backed up properly.
Access Your Wallet: Once you click on the confirm button, your MetaMask wallet will be ready to use. You are now able to send, receive, and store Ethereum-based assets.
MetaMask: Security & Privacy
Why MetaMask Stands by Users’ Right to Privacy?
- MetaMask is non-custodial, which means only you have access to your funds and private keys.
- MetaMask does not require email verification, KYC (Know Your Customer), or identity verification like centralized exchanges.
- Your data is stored on your device, so neither MetaMask nor any third party can access it.
What to Know About the MetaMask Extension’s Permissions?
When you install the MetaMask browser extension, it will ask for permission to “read and change all your data on the websites you visit.”
This is necessary because:
- MetaMask injects Web3.js, a Javascript object, into every website you visit in order to allow blockchain interactions.
- It doesn’t change the website; it only gives Web3 access for dApps.
- You can sandbox MetaMask using a separate browser profile dedicated to Web3 usage, provided that no security concerns are present.
How to Secure your MetaMask wallet?
Never share your secret recovery phrase. If someone gets it, they can hijack your wallet. There are a few more steps to secure your MetaMask wallet, such as those below:
- Use Hardware Wallet: Connect MetaMask with a hardware wallet (Ledger, Trezor, etc.) to add more security.
- Stay Safe From Phishers: Make sure to connect your MetaMask only to the legit site.
- Use the Latest Version of MetaMask: Updates generally have bug fixes and security improvements that help enhance security.
MetaMask for Transactions
How to Fund Your Wallet?
Buy Crypto Using Debit or Credit Card: MetaMask employs third-party payment providers, such as MoonPay, Wyre, or Transak, to facilitate fiat-to-crypto purchases directly.
Getting Crypto from Another Wallet: If nothing else works, just click on “Receive,” copy your wallet address, and share it with the sender.
Transferring Crypto from a Centralized Exchange (CEX): Transfer crypto from exchanges like Binance or Coinbase to your MetaMask wallet by entering your address in the withdrawal section of the exchange.
Sending and Receiving Crypto: To send crypto, you enter the recipient’s wallet address and the amount of crypto you wish to send, then adjust gas fees before confirming. This means to receive crypto, you only need to give the sender your wallet address or QR code.
How to Connect MetaMask to Decentralized Applications (dApps)
- Go to the dApp (like Uniswap, Aave, or OpenSea).
- Click “Connect Wallet” and choose MetaMask.
- Accept the connection, and you can now interact with the dApp.
