It links the browsers to the ETH platform and allows you to save keys for Ethereum and ERC-20 tokens on all compatible browsers.
Moreover, Metamask works hand in hand with two exchange platforms - Coinbase and ShapeShift. It lets users buy Ethereum straight from both platforms along with ERC-20 tokens.
Metamask is user-friendly and includes various noteworthy features like:
MetaMask doesn't often maintain any personal data since the software is decentralized and non-custodial. A user-generated passcode during setup, biometric data on smartphones, and a unique 12-word seed phrase for recovery protect the wallet.
Users can use their MetaMask wallet to conduct commerce and swap coins or NFTs, but the program advises that blockchain activities are not confidential. They label conversations as "anonymous users." The wallet identity serves as an alias for the customer because the wallet openly discloses all transactions on the blockchain.
You can access Metamask as an in-browser program on your desktop or laptop. Additionally, it is a mobile application available on both major app stores. Its popularity comes from its seamless integration with popular crypto websites, such as NFT marketplace OpenSea.
One of the most attractive features of MetaMask is that it is completely free to use.
The platform does not charge members any transaction fees while transacting in bitcoins and NFTs.
Given how quickly the exchange needs to execute transactions, consumers will be liable for paying any gas fees to the blockchain.
