Meet W3A Snap: Your Personal Security Guard in MetaMask


Nov 23, 2023

Like Batman to Gotham City, Web3 Antivirus is Web3's defender. And now, W3A Snap joins as its reliable sidekick, just like Robin.

The Web3 Antivirus security suite is expanding — now you can fortify your MetaMask with W3A Snap. Using both the browser extension and the Snap greatly enhances your protection against scams and facilitates a trouble-free Web3 experience.

What is a Snap?

Snap is a plugin for MetaMask, allowing you to customize the wallet’s functionality. Say, connect to dApps running on blockchains that MetaMask doesn't usually support or to manage tokens not typically recognized by the wallet, such as Bitcoin.

Once you've installed the Snap, a "WEB3 ANTIVIRUS" tab will appear in the MetaMask window. This is where you will find all the security alerts.
