MetaMask Snaps are third-party extensions that developers can build and users can install directly into the MetaMask wallet, adding new functionality — from supporting additional blockchains to providing extra transaction insights — without needing MetaMask’s own core team to build every feature themselves.
Key Takeaways
- Snaps let independent developers extend MetaMask’s functionality, similar to how browser extensions add features to a web browser.
- Common Snap categories include interoperability, transaction insights, and notifications.
- Installing a Snap requires an updated MetaMask extension and browsing the official MetaMask Snaps directory.
- Because Snaps are built by third-party developers, their security and trustworthiness varies — reviewing reputation and permissions before installing matters.
- The Snaps model reflects a broader trend of core wallet infrastructure becoming an extensible platform.
Our Take
The Snaps model mirrors a pattern that’s proven successful in other software ecosystems — browser extensions, app store plugins — where a core platform stays focused on its main function while an open ecosystem of third-party developers extends functionality.
The trade-off is that installing a Snap means trusting third-party code with some level of access to your wallet’s context — the same security instincts that apply to any third-party software installation apply here too.
FAQs
Are all MetaMask Snaps built by the MetaMask team?
No — Snaps are primarily built by independent, third-party developers, which is what allows the ecosystem to extend functionality faster than the core team could alone.
Are Snaps safe to install?
Security varies by individual Snap — reviewing a Snap’s reputation, permissions, and developer before installing is a sensible precaution.
