- Peg
- The target price a stablecoin is designed to hold — usually $1 for USD stablecoins, but also EUR, GBP, gold, and other reference values.
- Depeg
- When a stablecoin's market price drifts away from its target. Small deviations are common; sustained or sharp moves are the danger signal.
- Peg stability
- How tightly a stablecoin has held its target over time, including penalties for real depeg events. Surfaces as a sub-factor inside the Safety Score, not as a standalone grade.
- DEWS
- Depeg Early Warning System. Per-coin 0–100 stress score from eight weighted sub-signals (supply contraction, pool stress, liquidity erosion, price confidence, cross-source divergence, blacklist activity, mint/burn flow, yield anomalies). Refreshes every 30 minutes; bands are CALM, WATCH, ALERT, WARNING, DANGER. Formula and bands in /methodology/.
- Safety Score
- Composite risk grade rendered A+ to F. Weighted average of four base dimensions — Liquidity / Exit (30%), Resilience (20%), Decentralization (15%), Dependency Risk (25%) — multiplied by a peg-stability factor. Weights, thresholds, and grade bands documented in /methodology/. Surfaces on every detail page and the Safety Scores leaderboard.
- Report Card
- Per-coin grade artifact rendered on every detail page. Breaks the Safety Score down into its component pillars so you can see where a coin earns or loses points.
- Liquidity grade
- How easily you can exit a stablecoin on-chain. Letter grade (A+ to F) backed by a 0–100 score that blends TVL depth (30%), 24h volume (20%), pool quality (20%), durability (20%), and pair diversity (10%). Inputs read from Curve, Balancer, Uniswap V3, Aerodrome, Velodrome, and other tracked venues.
- Chain Health Score
- 0–100 composite per chain combining stablecoin quality, chain environment, dominance concentration, peg stability across hosted assets, and backing diversity. The lede on /chains/.
- Dependency risk
- How much a stablecoin depends on other stablecoins or their backing assets — hidden exposure that can cascade during stress.
- PYS
- Pharos Yield Score. Risk-adjusted yield ranking that weights raw APY against the underlying stablecoin's Safety Score, source freshness, benchmark context, and APY consistency. Surfaces on the yield page and on every coin detail page that has live opportunities.
- PSI
- Pharos Stability Index. 0–100 ecosystem health score combining active-depeg severity, market-cap breadth, DEWS stress breadth, and 7-day market-cap trend. Refreshes every 30 minutes. Also surfaces as 'Stability Index' across the app.
- Frozen
- A tracked stablecoin whose data collection has been halted but whose detail page remains as a read-only archive. Different from cemetery entries: frozen coins still have their original page; cemetery entries are summarized obituaries only.
