# Safety Scores Changelog
[All versions](https://pharos.watch/methodology/scoring-changelog/)
## v4.1 - Liquidity weight increase + reclassifications
**Effective:** 2026-02-27
Liquidity weight raised to 30% as the most defining stablecoin attribute. Five coins reclassified to decentralized.
- Weights: Liquidity 25->30%, Resilience 25->20%
- crvUSD, FRXUSD, USR, GYD, ALUSD reclassified from centralized-dependent to decentralized
Liquidity 25%→30% (“swappability is the most defining aspect of a stablecoin”), resilience 25%→20%.
5 coins reclassified from centralized-dependent to decentralized: crvUSD, FRXUSD, USR, GYD, ALUSD.

## v4.0 - Peg stability becomes a multiplier
**Effective:** 2026-02-27
Biggest structural change: peg stability removed from weighted dimensions and applied as a post-hoc power-curve multiplier.
- Peg applied as final *= (pegScore/100)^0.20 instead of 25% dimension weight
- Grade thresholds lowered 5 points to compensate for structural deflation
**Biggest structural change.** Peg Stability removed from the weighted base dimensions entirely and applied as a post-hoc power-curve multiplier:
```text
final = base × (pegScore / 100) ^ 0.20
```
pegScore | Multiplier | Impact
--- | --- | ---
100 | 1.000 | none
90 | ≈0.979 | −2%
50 | ≈0.870 | −13%
10 | ≈0.631 | −37%
0 | 0 | dead
Grade thresholds lowered 5 points to compensate for structural deflation. Minimum rated base dimensions reduced from 3 to 2.
