Score Breakdown

How the TrustGrade algorithm computed this score.

Wilson Score Lower Bound

98.85%

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

Bayesian Posterior

78.93%

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

Incident Penalty

-0.0%

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

Volume Bonus

+6.30

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
Liquidity Health 85.0% ±7 +4.90
Audit Coverage 80.0% ±6 +3.60
Exploit History 100.0% ±8 +8.00
Team Transparency 90.0% ±4 +3.20
Decentralization 58.0% ±5 +0.80
Market Cap Resilience 63.3% ±5 +1.33
Token Longevity 58.0% ±4 +0.64

Why this grade?

Strong trust signals with high statistical confidence. Liquidity Health above average. Audit Coverage 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 tokens.
