The MetaMask wallet has 10 million MAU (Monthly active users). MetaMask is a trusted and secure crypto wallet that comes as a mobile app and a browser extension. It’s a digital wallet that can easily be integrated with different blockchain-based applications. Read on for our MetaMask review to learn about the key attributes of this cryptocurrency wallet and how it rapidly became the world-leading noncustodial wallet.

But before we go further with our ultimate review, let’s briefly look into various cryptocurrency wallets that exist in the cryptoverse.

Crypto Wallets

Cryptocurrency users need cryptocurrency wallets to manage their digital assets. A crypto wallet is used to store your private keys, which are passwords that grant direct access to your crypto assets. You need a private key to sign a transaction to send or receive cryptocurrencies.

Crypto wallets don’t store your crypto, which is held on the blockchain. Instead, they store your private keys, which prove the ownership of your digital money and allow you to make transactions.

Types of Crypto Wallets

Crypto wallets can first be divided into two broad categories: Custodial wallets and Non – Custodial wallets. 

Custodial Wallets 

A custodial wallet mirrors the banking system as we know it. Your private key is in control of a third party, which you trust to keep your assets secure and give you access whenever you need to trade them. This type of wallet is easy to use and requires less responsibility, but trusting a third party with the security of your assets comes with the risk of loss. 

Noncustodial Wallet

A noncustodial wallet is a safer alternative. Here, only you are in full control over your assets and private key. Noncustodial wallets come with a lot of responsibility, as you are solely responsible for securing your private keys from hackers and getting lost. Noncustodial wallets could be browser-based or hardware. Some trendy ones are MetaMask,  Ledger Nano X, and Trezor One. Paper wallets are another type of noncustodial cold storage wallet. They are pieces of paper with private keys and public keys printed on them.

Crypto wallets can also be categorized into two groups: 

  • Software wallets 
  • Hardware Wallets

Software or Hot Wallets

A software wallet is an online wallet that stores your private keys in an app or other software. This makes managing your crypto as easy as using an online bank account.

There are three types of hot wallets:  

  • Web Wallets allow you to interact with the blockchain via your browser interface. 
  • Desktop wallets: These come in the form of downloadable software stored on the local disk of your computer, i.e., Atomic wallet. 
  • Mobile Wallets: These are like desktop wallets for your smartphone downloaded in an app, i.e., the Coinstats Wallet and the Trust Wallet. 

Hardware or Cold Wallets

Hardware or cold wallet stores your private key offline. These are physical detachable hardware devices similar to flash drives that are only connected to a computer when you want to use your crypto. Examples are Ledger Nano wallets and Trezor – Model T Wallet. Hardware wallets are considered very secure because the keys are stored offline.

MetaMask Defined

MetaMask wallet is one of the most widely used web-based Ethereum wallets. MetaMask serves as a bridge between your standard browser and the Ethereum blockchain. It was created by ConSenSys in 2016 and has raised over $250m, with a current valuation of $3.2bn.

MetaMask comes as a browser extension and mobile app that lets you access the Ethereum blockchain from the comfort of your web browser. It provides an essential utility for blockchain newcomers, token traders, crypto gamers, and developers. MetaMask equips you with everything you need to manage your digital assets, i.e., a key vault, secure login, token wallet, and token exchange.

MetaMask provides the simplest yet most secure way to connect to blockchain-based applications, enabling you to stay in control when interacting on the new decentralized web. It’s an Ethereum digital wallet that simplifies access to decentralized applications (dApps), including crypto exchanges, gaming platforms, and staking opportunities.

MetaMask is supported by Google Chrome, Firefox, Edge, and Brave browsers. It allows you to manage ETH-based tokens like ERC-721 and ERC-20 and digital assets from Binance Smart Chain and other blockchains. MetaMask provides flexibility to switch between other networks and the convenience of connecting multiple wallets.


Decentralized applications (dApps) are digital applications or programs that exist and run on a blockchain or peer-to-peer (P2P) computer network instead of a single computer. Most common dApps run on the Ethereum blockchain. Decentralized apps run on an agreement between two people encrypted in a computer code known as a smart contract.

Unlike Defi, which is mainly designed for financial activities, dApps are built for various purposes, i.e., gaming, education, gambling, etc. 

MetaMask integrates with a variety of dApps built on the Ethereum blockchain. Examples of common dApps are: 

  • Uniswap (Exchange)  
  • Axie Infinity (Games) 
  • Uniswap V3 (DeFi)
  • OpenSea (Marketplace)
  • ShibaSwap (DeFi) 


DeFi stands for decentralized finance and enables you to carry out regular financial activities on the blockchain without the centralization of banking institutions. MetaMask provides unrivaled access to DeFi without compromising security, operational efficiency, or compliance requirements. The most common DeFi apps built on the Ethereum blockchain are MetaMask Swap, Sushi, Hex, and AAVE.

MetaMask Swap 

MetaMask Swap allows users to swap tokens directly from their wallets. Swap combines data from multiple decentralized exchange aggregators, professional market makers, and individual DEXs. 

The MetaMask Swap feature enables any Web3 or DeFi user to easily access the tokens they need for the sites they use. By integrating data from the largest liquidity sources in the ecosystem — including Uniswap, AirSwap, 0x API,, Paraswap, Totle, and — MetaMask Swap lets users access all decentralized liquidity sources from one place.


Sushiswap is a decentralized exchange built on the Ethereum network. You can use Sushi Swap to trade one cryptocurrency for another directly — it can’t be used to trade fiat for crypto or vice versa. 


HEX is just a single smart contract (“App”) on the Ethereum ecosystem. It’s the first certificate of deposit on the blockchain and follows the ERC20 standard making it compatible with many wallets and exchanges. You have to pay a fee to the Ethereum network every time you send HEX.


AAVE is a decentralized finance (DeFi) protocol built on the Ethereum network that lets people lend and borrow cryptocurrency without having to go through a centralized intermediary. When lending, they earn interest; when borrowing, they pay interest.
