Collateral Tiers
Prime, Core, and Edge collateral labels used for registry seeding and display context.
Collateral tiers are registry labels used to seed reviews and explain asset context. They are not the live Asset Composition scoring formula.
The current asset vector scores category-specific dimensions, applies caps, and then applies vault-level portfolio mechanics. See Asset Composition for the scoring path.
How Tiers Are Used Now
| Use | Behavior |
|---|---|
| Registry seeding | Initial hints for asset review and migration backfills |
| Display context | Human-readable labels for familiar collateral quality bands |
| Analyst review support | Starting point for evidence collection, not a substitute for dimensions |
| Live scoring | Dimension scores, caps, overlays, staleness, and portfolio adjustments |
Prime Label
Highest-liquidity assets with long track records and broad adoption.
Examples include ETH, WETH, USDC, USDT, WBTC, cbBTC, wstETH, rETH, and weETH.
Core Label
Established assets with smaller liquidity, more complex mechanisms, or narrower operating history.
Examples include DAI, USDS, sDAI, sUSDe, USDe, GHO, FRAX, LUSD, LBTC, LINK, and ARB.
Edge Label
Unlisted tokens, low-liquidity assets, newer wrappers, assets with explicit Edge overrides, or assets that have not yet passed review.
Unknown assets enter review through conservative fail-safe handling until enough evidence exists for category scoring.
Reading Vault Outputs
Vault outputs may still expose collateral labels for analyst context. Do not compute the asset vector from these labels. Use risk_vectors.asset, asset dimensions, caps_applied, hard_fail_flags, review_status, and risk_score_breakdown where available.
