MetaMask is a software crypto wallet that comes as a browser extension. It also has a mobile application. The browser extension is available for:
It doesn’t matter what type of device you are using, is available both for IOS and Android devices.
What are MetaMask functions?
First, it stores your private key and allows you to store your crypto. A very common misunderstanding is that many beginners believe that cryptocurrencies are stored in MetaMask or in any other crypto wallet. This is incorrect; a crypto wallet like MetaMask only stores your public key and your private key, then uses your private key to sign and approve transactions.
Consider the public key as your bank account number or your PayPal email address. The private key is similar to the pin to your debit card or as the password to your PayPal account. If someone knows your private key, they can get access to or spend all of your money.
The other and most important function of Metamask or other web3 wallet, is that it lets you interact with decentralized applications like Blast. For example you can sign-in to the app using Metamask, or collect a prize from a prize-pool.
