MetaMask Review
What is MetaMask?
MetaMask is a cryptocurrency wallet and gateway to blockchain Dapps. Created by ConsenSys in 2016, MetaMask is now trusted by over 21 million users worldwide to keep their data and crypto secure.
Predominately created as an Ethereum-based wallet and more recently become popular with Ethereum Layer-2s like Arbitrum/Optimism and alternative networks such as Binance Smart Chain.
The wallet is most commonly used as a browser extension, with over 4 million downloads and provides users with a gateway to using blockchain apps. However, MetaMask mobile is also available for Android or iPhone, where users can sync the app with the account on their desktop in a matter of seconds.
MetaMask equips you with everything you need to manage your digital assets, including a key vault, secure login, token wallet, and token exchange.
With the ability to connect to both Ethereum and Binance Smart Chain-based DApps, users can use their tokens to trade on decentralized exchanges, play games, and spend in gambling applications. It’s also a great entry point for DEFI, providing users with a way to interact with decentralized finance applications such as the likes of UniSwap, PancakeSwap, Compound, or Zapper.Fi.
What is a Web3 Wallet?
You’ll often hear MetaMask described as a Web3 wallet. This is because MetaMask enables users to interact with decentralized apps (dApps). In fact, MetaMask is also the most widely supported wallet across the larger DeFi ecosystem.
Web3 Wallets are the software that allows you to interact with Web 3.0, a third generation of the internet. Web 3.0 applications are mostly referred to as decentralized applications or dApps, and these are often powered by the blockchain. DApps that exist on the blockchain will often need the user’s tokens to use its features, such as game tokens, trade, stake, earn interest, etc. By using MetaMask, you are able to use these dApps while keeping control of your tokens.
Metamask Security
MetaMask is a non-custodial wallet, which means it doesn’t host or store your assets. Instead, it generates passwords and keys locally on your device, so only you can access your accounts and data. It supports various blockchains, such as Ethereum, Binance Smart Chain, Polygon, and others.
Regarding security, MetaMask does not store any of your personal or private data on its servers. All data is encrypted in your browser and protected via your MetaMask password. To further secure your account, you can only restore lost MetaMask accounts using your Secret Recovery Phrase.
However, MetaMask is a software, or hot, wallet, which means it stores the keys to your crypto assets using software on an internet-connected device. While it offers encryption and password protection, it’s essential to follow security best practices to ensure the safety of your assets.
You can find more information on privacy and security by visiting Metamask’s support page.
Is MetaMask Safe?
MetaMask is only as safe as your ability to keep your seed phrase or private keys secure. The wallet is also deemed as a “hot wallet” as it connects to the internet; therefore, there are also risks.
It is recommended that you only keep small amounts of assets within the wallet (longer-term), or one of the safest ways to use MetaMask is by connecting it to a hardware device, such as a Ledger or a Trezor. In this way, MetaMask is working as a middleman, and your funds are not exposed.
MetaMask Private Keys
MetaMask is a non-custodial wallet; therefore, if you lose your private key/seed phrase, MetaMask cannot help you to recover your wallet or funds. When creating your MetaMask account, you will be provided with your12-word phrase. You will need towrite down and store your seed phrase offline, as this will be the onlyway to recover your funds should your device crash or your browser reset.
Also, never share your seed phrase or your private key with anyone, as you will lose complete control over your wallet.
Metamask Features
Portfolio
MetaMask Portfolio is a feature that allows you to view and manage your MetaMask accounts and their assets in one place. It aggregates values from up to 10 of your accounts and displays your total holdings, giving you an at-a-glance summary of their value in your chosen currency.

Metamask Mobile App
MetaMask also provides a mobile app allowing users to manage their Ethereum private keys on the go. The mobile app serves as a wallet for Ether and other tokens and enables users to interact with decentralized applications (dApps) just like the browser extension. By offering a convenient and user-friendly platform, MetaMask mobile app aims to enhance the experience of accessing and interacting with the decentralized web on mobile devices.
MetaMask Swaps
MetaMask users can not only store but also compare and swap tokens directly within their wallets. The token swaps feature fetches quotes across multiple decentralized liquidity sources to ensure users the best available prices with the lowest network fees.
The feature is initially available to users of the MetaMask extension on the Firefox browser, with plans to be rolled out to other browsers and mobile apps.
Up to now, MetaMask users would need to go to the website of a specific decentralized exchange or exchange aggregator, sign in, approve each token on each dex, costing money in gas, and then run the swap.
However, now MetaMask has collaborated with ConsenSys to build Swaps: a feature that enables any Web3 or DeFi user to access the tokens they need for their sites easily.
