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 C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Is ChatArena safe?

Public trust evidence for ChatArena 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 ChatArena publish package provenance?
No published build provenance is currently detected for ChatArena. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does ChatArena have an OpenSSF Scorecard?
ChatArena has an OpenSSF Scorecard score of 4.7/10. 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 ChatArena actively maintained?
Stale. The repository has not been pushed to in 360 days. Consider whether the project is still being maintained.
What license does ChatArena use?
ChatArena ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are ChatArena's commits signed?
97% of the last 100 commits to ChatArena 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 ChatArena?

For maintainers

HVTrust scores ChatArena 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.
