Security Snaps introduce a new tab in the transaction prompt, allowing Snaps to provide important security info about a transaction you're about to submit.

Introducing Security Snaps

Security Snaps take your transaction journey to the next level by enabling Snaps to offer essential transaction insights, such as (but not limited to!):

  1. Phishing database checks
    Know if the recipient address is linked to any known phishing databases, giving you an extra hand in figuring out whether you might be interacting with a malicious address.
  2. Transaction simulations
    A Snap could help you determine whether a transaction might succeed or fail and predict any state changes by simulating the transaction locally, or by using AI.

Frequently asked questions (FAQ)

Are all Snaps equipped with insights about my transactions?

Not every Snap offers insights on your transactions. Check individual Snap descriptions to see if they make use of insights. When installing a Snap, you can also see whether it provides transaction insights by checking the permissions it requests:

Are there any privacy concerns when using Security Snaps?

Different types of Snaps access different information based on the permissions granted at installation. Any user data you share with a third-party-developed Snap will be collected directly by Snaps developers; MetaMask does not have access to this data. Only install Snaps from developers that you trust, and always check the privacy policy and terms of use of a Snap before installation.
