# Safety Scores Changelog

[All versions](https://pharos.watch/methodology/scoring-changelog/)

<a id="scoring-v1-0"></a>

## v1.0 - Initial implementation

**Effective:** 2026-02-25

First release with six weighted dimensions: Peg Stability, Liquidity, Safety, Resilience, Decentralization, and Dependency Risk.

- Six dimensions with grade thresholds from A+ (>=97) to F (>=0)
- Minimum 3 rated dimensions required for overall grade

Six weighted dimensions:

<a id="scoring-v1-weighted-dimensions"></a>

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%
