Tiers & Disqualifications
Prime, Core, and Edge tier definitions with hard disqualification rules.
Tier Definitions
| Tier | Score Range | Profile |
|---|---|---|
| Prime | 8.0 – 10.0 | Mature code, multiple audits, simple strategy, timelocked governance, no recent incidents |
| Core | 5.0 – 7.9 | Audited with shorter track record, moderate complexity, or permissive governance |
| Edge | 0.0 – 4.9 | Unaudited, <6 months live, complex aggregation, or recent incident |
Tiers are relative risk classifications, not recommendations. Prime does not mean "safe" — it means strongest observable security characteristics among tracked vaults.
Hard Disqualifications
These rules override the composite score calculation:
No Audit → Forced Edge
If the deployed protocol version has no audit, the vault score is capped at 4.9 (Edge tier). This is the single most impactful override in the model.
No audit means:
- No security audit report exists for the specific deployed version
- An audit of a different version does not count
- The protocol may be audited, but the specific contract version is not
Multiple Zero Sub-Scores → Forced Edge
If 2 or more risk sub-components score exactly 0, the vault is forced to Edge tier. This prevents a vault from achieving a high composite score while having critical gaps.
Single Zero → Cannot Reach Prime
If any single sub-component scores 0, the vault cannot achieve Core tier or above. A zero in any dimension indicates a critical risk gap.
Override Rules Summary
| Condition | Effect |
|---|---|
| Unaudited protocol version | Score capped at 4.9 (forced Edge) |
| 2+ sub-scores at zero | Forced Edge |
| Any sub-score at zero | Cannot reach Core |
| Incident < 30 days | Platform capped at 2 (forces Edge) |
| Incident 30-90 days | Platform capped at 5 (forces Core max) |
Warning Indicators
Beyond tier classification, vaults can have warning flags:
| Warning | Threshold |
|---|---|
| Low TVL | < $100,000 |
| New vault | < 1 month old |
| Recently deployed | < 3 months old |
| Stale audit | Audit > 18 months old |
| Outperforming APR | > 5× category average |
