Maple Finance
Mixed trust signals — meaningful risk factors detected. 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) | 72.0% | ±7 | +3.08 | |
| Audit Coverage | 80.0% | ±8 | +4.80 | |
| Exploit History | 40.0% | ±9 | -1.80 | |
| Team Transparency | 70.0% | ±4 | +1.60 | |
| Governance Decentralization | 58.0% | ±5 | +0.80 | |
| Oracle Resilience | 85.0% | ±4 | +2.80 |
Why this grade?
Mixed trust signals — meaningful risk factors detected. 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 6 weighted optional signals specific to defi protocols.
⚠️ Notable risk: This entity has an elevated incident penalty of 15.4%, which significantly impacts the final score.
