MetaMask is a non-custodial cryptocurrency wallet that allows users to store, manage, send, and receive their cryptocurrencies and Non-Fungible Tokens. It can be used as a browser extension as well as a mobile application. MetaMask is one of the most popular and recognizable wallets globally. Through MetaMask, users can securely connect to numerous decentralized applications (dApps) and perform various operations directly within the wallet.
I. History of MetaMask
MetaMask was created in 2016 by Dan Finlay and Aaron Davis, employees of ConsenSys, a blockchain software technology company founded by Ethereum co-founder Joseph Lubin. The development of MetaMask aimed to simplify user interaction with the Ethereum blockchain and its ecosystem.
As the Ethereum ecosystem expanded, the functionality of MetaMask continued to grow. In 2017, the wallet began supporting ERC-20 tokens (tokens built on the Ethereum blockchain), significantly enhancing the usability for users to participate in token sales and various DeFi applications.
In 2019, MetaMask launched a beta version of its iOS and Android mobile applications, and the official release followed in 2020, supporting cross-platform synchronization, allowing users to access their wallets on their mobile devices. The rise of DeFi in 2020 and 2021 significantly drove the adoption of MetaMask, which then began supporting other blockchains, starting with Binance Smart Chain in 2020, and later expanding to other Ethereum Virtual Machine (EVM)-compatible blockchains such as Polygon, Avalanche, and Fantom.
ConsenSys reported in April 2021 that MetaMask had over 5 million monthly active users. Over time, MetaMask has continued to introduce new features, allowing users to perform token swaps, cross-chain bridges, staking, and fiat withdrawals directly within the application. As of September 2023 to January 2024, ConsenSys reported over 30 million monthly active users.
II. Features and Characteristics
MetaMask offers a range of features aimed at providing a seamless and secure experience for cryptocurrency users. It allows users to securely store, send, and receive Ethereum and ERC-20 tokens, manage multiple wallet addresses, and import/export private keys.
Although MetaMask initially focused on Ethereum, it has since expanded to support multiple blockchains, including Binance Smart Chain, Avalanche, Fantom, and Polygon, as well as Ethereum Layer 2 solutions.
MetaMask also provides powerful transaction management features, including the ability to view and manage transaction history and customize the gas fees for transactions. Users can perform token cross-chain bridges, instant token swaps, and direct fiat-to-crypto purchases within the application. Ethereum users can also stake directly within the app, without the need to navigate to other applications.
MetaMask has several security features, including password protection and private key encryption, support for hardware wallets like Ledger and Trezor, and seed phrase backup and recovery options. In 2024, MetaMask integrated security alerts from Blockaid to help users prevent malicious transactions.
III. How to Create a MetaMask Account
Users first need to install MetaMask as a mobile application or browser extension. To install the browser extension, users can visit the MetaMask website, click "Download," and select the desired browser (Chrome, Firefox, Brave, or Edge). Once installed, users can follow the prompts to add the extension. Mobile users can download the MetaMask app from the iOS App Store or the Google Play Store for Android.
After the installation is complete, users can open the extension or mobile app and click "Get Started." Selecting "Create a Wallet" will begin the setup process, where users will need to create a password. This password will be used to unlock the wallet on the user's device. After creating the password, MetaMask will provide each user with a 12-word secret recovery phrase. It is crucial to write down this phrase in the correct order and store it in a secure offline location, as it will be necessary to recover the wallet if the user forgets the password or needs to restore the wallet on a new device. Once the seed phrase is confirmed, the setup is complete, and the MetaMask wallet is ready for use.
IV. Risks of Using MetaMask
Despite MetaMask's security features, there are still risks associated with using cryptocurrency applications, and users should always remain vigilant. Phishing attacks are a significant risk, where attackers create fake websites or extensions that mimic MetaMask or other DeFi applications to steal users' private keys, seed phrases, or funds.
Additionally, if users accidentally lose their private keys, they will be unable to recover them, and they will lose access to their wallet's funds. To ensure the security of their assets, users should regularly check their account activity and increase their security awareness, avoiding the use of suspicious links or downloading untrusted applications.
