PowerPool
Fair trust profile for this defi protocol. TrustGrade score 62/100 (Grade C+).
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) | 60.0% | ±7 | +1.40 | |
| Audit Coverage | 82.0% | ±8 | +5.12 | |
| Exploit History | 78.0% | ±9 | +5.04 | |
| Team Transparency | 65.0% | ±4 | +1.20 | |
| Governance Decentralization | 55.0% | ±5 | +0.50 | |
| Vault Security | 72.0% | ±4 | +1.76 |
Why this grade?
Fair trust profile for this defi protocol. TrustGrade score 62/100 (Grade C+).
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 6 weighted optional signals specific to defi protocols.
