SEI
Generally trustworthy, but some signals introduce uncertainty. Liquidity Health 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 |
|---|---|---|---|---|
| Liquidity Health | 76.0% | ±7 | +3.64 | |
| Audit Coverage | 80.0% | ±6 | +3.60 | |
| Exploit History | 100.0% | ±8 | +8.00 | |
| Team Transparency | 90.0% | ±4 | +3.20 | |
| Decentralization | 56.0% | ±5 | +0.60 | |
| Market Cap Resilience | 58.9% | ±5 | +0.89 | |
| Token Longevity | 44.0% | ±4 | -0.48 |
Why this grade?
Generally trustworthy, but some signals introduce uncertainty. 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.
