Häufig gestellte Fragen

1. What is MetaMask Snaps? MetaMask Snaps allows users to add features and functionality to their MetaMask wallet. Individual Snaps are features created by third-party developers that MetaMask users can install directly into their wallet.

   We believe a decentralized internet that is accessible to all and owned by the people who use it, will give rise to human flourishing on an exponential scale. Whilst our roots are in Ethereum, and our expertise is grounded in building the leading self-custodial wallet, we appreciate that innovation occurs in many domains across the web3 ecosystem. With Snaps, we hope to capture the full extent of the innovation happening in web3, by enabling developers to bring their specialist expertise to building for our platform.

2. What is a Snap? A Snap is an application that adds features and functionality to MetaMask. Snaps can connect to blockchain protocols beyond Ethereum, show insights about transactions, display notifications, add new privacy and identity features, and much more.

3. Will MetaMask charge for MetaMask Snaps, or will it be free to use? The MetaMask Snaps platform is free to use. While there is no cost to install Snaps, an individual Snap might offer services that require payment, incur fees, or contain paid subscriptions.

4. Will new features come via MetaMask Snaps only, or will MetaMask still add features natively to the Extension and Mobile App? MetaMask will continue to build new features in the extension, mobile apps, and portfolio.metamask.io. Some new features may be built as Snaps.

MetaMask Snaps Open Beta FAQs

1. How is the MetaMask Snaps Open Beta different to the final version of MetaMask Snaps? The MetaMask Snaps Open Beta is different in that it will host a variety of allowlisted Snaps. Ultimately, our vision of MetaMask Snaps is to be fully permissionless, without any gatekeepers. MetaMask Snaps Open Beta is a first step to building this permissionless system.

2. Where can I install a Snap? During the MetaMask Snaps Open Beta phase, we recommend you install Snaps from the MetaMask Snaps Directory. You can also install Snaps from other websites.

3. Are there any other directories that host Snaps? During the MetaMask Snaps Open Beta phase, we recommend you install Snaps from the MetaMask Snaps Directory. We also gave a grant to a third-party directory to support a community-built directory, more information about that here. Snaps lassen sich auch von jeder Website aus installieren. This is in line with our vision of having a fully decentralized system where MetaMask is not a gatekeeper.

4. How do I know I'm installing a safe Snap? Snaps run in a sandboxed environment in MetaMask, and MetaMask uses a permissions model to restrict what a Snap can do.

   • Wenn ein Snap die Genehmigungen Kontoverwaltung verwendet, muss er von einem zugelassenen Sicherheitsprüfer überprüft und vom MetaMask-Snaps-Team manuell begutachtet werden, bevor er von MetaMask auf die Genehmigungsliste gesetzt werden kann.
   • Wenn ein Snap _geschützte_Genehmigungen verwendet, die Funktionen wie Netzwerkzugriff und Kommunikation mit Websites umfassen, muss er manuell vom MetaMask-Snaps-Team überprüft werden, bevor er von MetaMask auf die Genehmigungsliste gesetzt werden kann.
   • Wenn ein Snap offene Genehmigungen verwendet, wie etwa für die Anzeige von Inhalten und die Speicherung von Daten, kann er ohne die Genehmigungsliste installiert werden.

   Wenn Sie einen Snap installieren, können Sie die von ihm angeforderten Genehmigungen einsehen, um eine sachkundige Entscheidung zu treffen. Im MetaMask-Snaps-Verzeichnis können Sie Informationen zu jedem Snap einsehen, darunter Sicherheitsprüfungsberichte, Quellcode, Genehmigungen und Informationen zum Entwickler.
