How Do I Get MetaMask On My Desktop?

MetaMask is a browser-extension wallet that holds your crypto and signs transactions on Ethereum-based networks. You’ll need it to buy, view, and read your Stuff.io / Book.io media on Polygon. The official setup guide lives at support.metamask.io — that’s the source of truth if anything below looks out of date.

Quick browser-by-browser steps:

Chrome

1. Visit metamask.io and click Download.
2. Click Install MetaMask for Chrome. You’ll be sent to the Chrome Web Store.
3. Click Add to Chrome, then Add extension on the pop-up.

MetaMask opens automatically once installed. To pin it to your toolbar, click the jigsaw icon in the top-right and click the pin next to MetaMask.

Firefox

1. Visit metamask.io and click Download.
2. Click Install MetaMask for Firefox, then Add to Firefox in the new window.
3. Click Add on the pop-up.

Heads up: the Firefox listing shows the publisher as “danfinlay, kumavis” — that’s expected; they’re MetaMask core maintainers.

Brave

1. Visit metamask.io and click Download.
2. Click Install MetaMask for Chrome — Brave shares the Chrome Web Store, so this is correct.
3. Click Add to Brave, then Add extension on the pop-up.

Next step

Once MetaMask is installed and you’ve finished its setup wizard, head to How do I buy a digital media? to connect your wallet and make your first purchase.
