Evidence tiers · L0–L4

Every listing carries an evidence tier — a compact signal of how much on-registry evidence has accumulated. Tiers are monotonic: an asset only advances when every lower-tier condition is met.

L0

Self-attested

Wallet signed a registration. Nothing else.

L1

Documented

Registrant attached a public documentation URL — deed, invoice, photo, valuation, license.

L2

Endorsed

Three or more independent wallets have endorsed the listing.

L3

Verifier-endorsed

At least one badged professional verifier has endorsed the listing.

L4

Anchored

Everything above, plus the asset has been tokenized on the Portal.

Buyers can filter or sort by tier. A listing at L4 with zero disputes is a much stronger signal than a listing at L0.
