UXD
Strong trust signals with high statistical confidence. Peg Stability (90-day) above average. Collateral Quality above average.
Score Breakdown
How the TrustGrade algorithm computed this score.
Wilson Score Lower Bound
95% confidence interval lower bound on positive outcome rate. Penalizes small samples automatically.
Bayesian Posterior
Beta(α,β) posterior mean with sceptical prior. Adjusts observed rate toward conservative estimate.
Incident Penalty
Compound penalty: 1−(1−s)². 10% incidents → 19% penalty. 30% → 51%.
Volume Bonus
Log-credibility bonus: log₁₀(n)×k. More data = more confidence, diminishing returns.
Signal Contributions
Each signal's contribution to the final score. Positive = trust-building. Negative = risk-indicating.
| Signal | Value | Weight | Contribution | Visualization |
|---|---|---|---|---|
| Peg Stability (90-day) | 80.0% | ±9 | +5.40 | |
| Collateral Quality | 82.0% | ±8 | +5.12 | |
| Reserve Transparency | 78.0% | ±7 | +3.92 | |
| Depeg History | 80.0% | ±7 | +4.20 | |
| Redemption Mechanism | 70.0% | ±4 | +1.60 | |
| Regulatory & Legal Status | 65.0% | ±5 | +1.50 | |
| Market Cap Resilience | 72.0% | ±4 | +1.76 |
Why this grade?
Strong trust signals with high statistical confidence. Peg Stability (90-day) above average. Collateral Quality above average.
The TrustGrade algorithm combines the Wilson score lower bound (which requires substantial evidence to score high), a Bayesian posterior (which shrinks toward a conservative estimate when sample sizes are small), a compound incident penalty (which grows faster than linear), a log-credibility volume bonus, and 7 weighted optional signals specific to stablecoins.
