Why this verdict

PkgRadar discounts a release’s score when public reputation argues against novel malware. The verdict above already reflects these — the panel just explains what was applied.

Versions published: 55Established · −30% score
First published: Sep 2025
Publisher: metamaskbot

Effective trust discount applied: −30% (max across signals — discounts don’t stack). New install-lifecycle deltas vs the previous release would clear the discount.
