The check Morsel runs before you sign

Morsel simulates every request first and tells you what it found. What each result means.

Updated October 5, 2026

Before you approve a transaction from an app, Morsel runs it against the network to see what it would really do, and shows you the result.

  • Simulation passed, likely to succeed: read what it sends and receives, then decide.
  • Simulation Failed: the network says it would fail right now. Approving it would usually just cost a fee.
  • DANGER - Do Not Approve: Morsel found something malicious. Reject it and leave the site.

Morsel also blocks sites known for phishing, with a warning page. Never sign something you do not understand, even on a site you trust.
