What is MetaMask?
MetaMask, one of the most widely adopted browser extensions, was founded by Aaron Davis and blockchain company ConsenSys. It serves as a crypto wallet connecting to the Ethereum blockchain. With the significant utilities, users are able to to interact with the Ethereum ecosystem, which hosts a universe of decentralized applications (Dapps) without downloading an entire blockchain on their device.
Therefore, it is one of the best Ethereum wallet solutions to gain quick access to decentralized applications (DEX), game platforms, betting sites and many other applications.
MetaMask wallets are compatible with popular browsers such as Chrome, Firefox, Brave, and Microsoft Edge. It not only stores ETH funds but also holds tokens built on the protocol’s ERC-20 and ERC-721 standards.
History and key features

Prior to 2019, the Ethereum online wallet was only available as a desktop browser plugin for Firefox and Chrome. In September 2020, ConsenSys released the first official MetaMask mobile app for mobile devices on Android and iOS.

The mobile version offers the same functions as desktop browser-based extensions. Therefore, it provides a key vault, secure login, token wallet, and token exchange and allows users to browse DApps based on Ethereum. Despite a hot wallet that was connected to the Internet, MetaMask makes it easy to connect to cold wallets such as Ledger, CoolWallet, KeepKey and Trezor.
What is metamask fee?
MetaMask offers the default gas fee for every transaction, depending on the state of the Ethereum network. In addition, users are given the option to change gas fees and gas limits through an advanced tab for customization of parameters.
The difference between the fee and the limit: the fee is the cost of processing the transaction, while the gas limit is the highest gas fee that the user are willing to pay.
Note that gas fees determine speed of transaction processing on the second largest decentralized blockchain. The higher the price, the faster the confirmation time. MetaMask divides gas fee options into “Fastest, Fast and Slow.”
Is MetaMask safe?
The online nature of MetaMask limits its level of security compared to cold-storage offline wallets such as Trezor and Ledger. However, the significant feature of MetaMask is the quick access to Ethereum DApp with easy setup and availability on both desktop and mobile platforms. In fact, it’s hard to imagine how the DeFi field would have evolved without MetaMask.
According to MetaMask, they do not have any control over personal or private data on their servers and everything is protected or encrypted on the user’s browser and password.
However, MetaMask is still considered as a hot wallet, because it is a software wallet connected to the Internet to store crypto assets. Hot wallets are often less secure than cold wallets, which are offline storage of crypto assets on hardware, the most secure form of crypto asset storage.
In addition, the wallet’s option to set gas limits above or below the average fee allows users to choose the transaction speed and fee they have to pay.
