# Scoring Model & Methodology
> How Webacy calculates depeg risk scores for each stablecoin — weighted signals, risk tiers, threshold logic, and the 0–100 scoring model behind every grade.
How we calculate depeg risk scores for each token
For a quick reference of weights and tier thresholds, see "Scoring Methodology: Depeg Monitor - All Signals & Scores."
# Risk Tiers
Each token receives a score from 0-100 based on weighted risk signals. The score maps to a tier:
# Feature Weights
The final score is a weighted sum of normalized risk signals (each 0-1). Weights sum to 90%, leaving room for future features.
# Velocity & Momentum Scoring
Beyond the base score, we track how quickly risk is changing. Rapidly rising scores get boosted for earlier warnings.
📈 **Velocity**
Rate of score change (points/tick). Positive = worsening risk.
🚀 **Acceleration**
Change in velocity. Helps detect rapidly accelerating depegs.
⚡ **Momentum Boost**
Up to +15 points added when velocity exceeds threshold.
# Token Type Adjustments
Different token types have different expected behaviors. The model adjusts for this:
# Example Calculation
**Token:** USDC on Ethereum
**Price:** \$0.985
**Peg:** \$1.00
**Deviation:** 1.5%
# Hysteresis & State Machine
To prevent alert fatigue, tier transitions require sustained conditions:
* **Upgrade to Critical:** 1 tick above threshold
* **Upgrade to Warning:** 2 consecutive ticks above threshold
* **Upgrade to Watch:** 2 consecutive ticks above threshold
* **Downgrade to OK:** 2 consecutive ticks below clear threshold
