Score Breakdown

How the TrustGrade algorithm computed this score.

Wilson Score Lower Bound

82.06%

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

Bayesian Posterior

80.00%

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

Incident Penalty

-3.0%

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

Volume Bonus

+3.50

Log-credibility bonus: log₁₀(n)×k. More data = more confidence, diminishing returns.

Why this grade?

Moderate trust profile for this stablecoin. TrustGrade score 77/100 (Grade B).

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 5 weighted optional signals specific to stablecoins.
