A software crypto wallet called MetaMask is used to communicate with the Ethereum network.Users can utilize a MetaMask extension Chrome or a mobile phone app to manage their Ethereum Wallet and then use it to connect with the decentralized application. Consensys Software Inc., a blockchain software firm specializing in Ethereum-based infrastructure tools, is the company behind MetaMask. 

By using this extension, you may build and manage your own identity. As a result, any dApp that wants to publish a transaction in your blockchain will immediately notify you and only confirm the transaction to the blockchain after receiving your approval. Your transaction will only then be completed. The user has the option to reject it if he cannot remember performing a specific transaction or if he no longer desires to do so. Hence, they have a high level of security as a result.

But, you must provide the extension of particular rights to accomplish this.

This blog is for you if you want to resolve a problem with your MetaMask Extension.
