One of the new functionalities that MetaMask Snaps introduces is transaction insights.
Transaction Insights introduces a new tab in the transaction prompt, allowing Snaps to provide essential information about a transaction you’re about to submit.
Introducing Transaction Insights
Transaction insights take your transaction journey to the next level by enabling Snaps to offer essential insights, such as (but not limited to!):
-
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. -
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.
