HIGH Publisher changed: metamaskbot → GitHub Actions (on 2026-07-07) provenance

This version was published by a different npm account than previous versions on 2026-07-07. This could indicate a legitimate maintainer transition or an account compromise.

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v0.3.0

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.2.0

1 finding
LOW No provenance attestation provenance

v0.1.0

1 finding
