Score Breakdown

How the TrustGrade algorithm computed this score.

Wilson Score Lower Bound

0.00%

95% confidence interval lower bound on positive outcome rate. Penalizes small samples automatically.

Bayesian Posterior

39.18%

Beta(α,β) posterior mean with sceptical prior. Adjusts observed rate toward conservative estimate.

Incident Penalty

-93.8%

Compound penalty: 1−(1−s)². 10% incidents → 19% penalty. 30% → 51%.

Volume Bonus

+3.91

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) 0.0% ±9 -9.00
Collateral Quality 20.0% ±8 -4.80
Reserve Transparency 20.0% ±7 -4.20
Depeg History 0.0% ±8 -8.00
Redemption Mechanism 30.0% ±4 -1.60
Regulatory Compliance 40.0% ±5 -1.00
Market Cap Resilience 36.9% ±4 -1.05

Why this grade?

Significant trust concerns identified across multiple signals. Elevated incident rate (94% compound penalty). Peg Stability (90-day) below average. Collateral Quality below 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.

⚠️ Notable risk: This entity has an elevated incident penalty of 93.8%, which significantly impacts the final score.
