MetaMask

MetaMask is a cryptocurrency wallet created for easy and secure connection of the user to the blockchain, providing him with the ability to manage his funds. Articl​e from community CryptoDeFix. Allows you to manage accounts and keys in complete independence from the content of specific sites. This is a significant security improvement compared to storing keys on a central server or in local storage. MetaMask is available as a browser extension, and more recently as a mobile application. It combines a key vault, a cryptocurrency wallet, additional tools for managing digital assets, tools for connecting to blockchain-based applications (dapps).

By connecting to Ethereum-based applications, users can spend their coins in games, bet tokens in gambling applications and trade them on decentralized exchanges. Metamask also provides users with an entry point into the developing world of decentralized finance, or DeFi, by providing a way to access DeFi applications such as Compound and PoolTogether. Formally, this looks like a normal authorization via social networks on any Internet site. The most common use of metasmask is in the form of a browser extension. In this case, it is convenient to cooperate with Defi platforms. The application applies several different levels of security at once. All confidential data is generated completely on a computer/mobile device, so the safety of accounts depends only on the security of the computer — whether third parties have access to it, whether there are installed spyware and Trojans. This also means that the Metamask will not be able to help restore the password if it is lost. This can be done only with the help of the LED phrase.

The process of withdrawing cryptocurrency from the Metamask wallet is as elementary as the replenishment procedure.There are two types of withdrawals in the wallet:

1. Automatic. It is meant as a payment for services or the purchase of goods on websites. It happens automatically, you only need to confirm the transaction.
2. Manual. Withdrawal of cryptocurrency to another address.
