Safety Scores Changelog: v1 archive version history
Use this changelog to trace how Pharos changed the related scoring, data-source, threshold, or interpretation rules over time. Entries record the contract active at each release; archived rules are retained so historical charts and citations can be read against the rules active at the time.

v1.0Initial implementationFeb 25, 2026
Six weighted dimensions:
| Dimension | Weight | Approach |
|---|---|---|
| Peg Stability | 25% | pegScore passthrough, capped at 65 during active depeg, +3 bonus if last depeg > 12 months ago |
| Liquidity | 25% | liquidityScore from DEX data, HHI penalty (−5 if >0.5, −10 if >0.8) |
| Safety | 20% | Bluechip rating passthrough (A+=100 … F=25), NR if no rating |
| Resilience | 15% | 2-factor: chain distribution 60% + freeze rate 40% |
| Decentralization | 10% | 3-tier: decentralized=95, centralized-dependent=70, centralized=50 |
| Dependency Risk | 5% | CeFi-Dependent only, unweighted avg of upstream scores |
Grade thresholds: A+≥97, A≥93, A−≥90, B+≥85, B≥80, B−≥75, C+≥70, C≥65, C−≥60, D≥50. Minimum 3 rated dimensions required.
Day-one patches
- Dependencies switched from unweighted to weighted averages
- Dependency renormalization fix: partial backing properly penalized via self-backed blending
- Peg +3 bonus restricted to coins with actual depeg history
- NAV tokens included in grading
- Rebalanced: dependency 5%→15%, resilience 15%→10%, decentralization 10%→5%
