Maintainer Checklist

Raise Scorecard signals Current OSSF Scorecard is 3.5/10. Tighten the weakest checks to improve public safety evidence.

Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.

Refresh maintenance signals The repo was last pushed 602 days ago. Fresh activity helps separate stable projects from stale ones.

In UI & App Builders

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage A is separate — it grades how many independent signal types back the score (4 of 5), so a high score on thin evidence stays visible. Full methodology →

Is Bolt safe?

Public trust evidence for Bolt is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.

Does Bolt publish package provenance?

No published build provenance is currently detected for Bolt. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does Bolt have an OpenSSF Scorecard?

Bolt has an OpenSSF Scorecard score of 3.5/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.

Is Bolt actively maintained?

Stale. The repository has not been pushed to in 602 days. Consider whether the project is still being maintained.

What license does Bolt use?

Bolt ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Bolt's commits signed?

65% of the last 100 commits to Bolt are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

Maintain Bolt?

For maintainers

HVTrust scores Bolt from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
