Across
Exceptional trust profile for this generic entity. TVL Stability (30-day) above average. Audit Coverage 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 |
|---|---|---|---|---|
| TVL Stability (30-day) | 87.9% | ±6 | +4.55 | |
| Audit Coverage | 100.0% | ±8 | +8.00 | |
| Exploit History | 100.0% | ±10 | +10.00 | |
| Team Transparency | 90.0% | ±4 | +3.20 | |
| Multi-chain Support | 30.0% | ±4 | -1.60 | |
| Volume Health | 64.1% | ±4 | +1.13 | |
| Bridge Longevity | 82.5% | ±4 | +2.60 |
Why this grade?
Exceptional trust profile for this generic entity. TVL Stability (30-day) 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 bridges.
✅ Exceptional: This entity scores in the top tier of the TrustGrade methodology, indicating strong trust signals across all measured dimensions.
