For those who are not aware of, MetaMask just release their version 8 which focuses more on security and privacy.
Who haven't upgraded or not aware of the latest version, then please do so.
Unparalleled Privacy Control
Most wallets today either manage a single account, or expose the currently selected user current account to all connected sites — broadly revealing users’ private information.
In MetaMask V8, when you connect to a website, you have the option to select one or more accounts to associate with that website or create a new account just for that site. You decide what each site has access to.
Cutting Edge Security
LavaMoat is Live and in Production!
Nothing is more important than your security at MetaMask. Our new LavaMoat tool helps raise the bar of security for nearly any JavaScript project.
MetaMask is a web and JavaScript-based wallet. JavaScript often gets a bad reputation because untrusted code is often pulled into production environments. For a wallet, this is more dangerous than ever.
LavaMoat is a set of tools we’re building that uses Secure EcmaScript to confine every third-party dependency in a piece of JavaScript code at build time. We hope to eventually confine every dependency in our entire wallet, greatly protecting us and our users from the category of “supply chain attacks”.
