Verification policy

What a record proves.

An explorer is only useful if its claims are precise. Every field on this explorer belongs to one of three tiers, and the page labels which.

Provenance tiers

Where each field comes from.

On-chain

Written to Base and independently verifiable by anyone, without trusting any operator.

  • Contract address
  • Token ID
  • Metadata hash
  • Transaction hashes on ledger entries

An on-chain record proves that a claim was issued against a token — not that the physical item matches its description.

Operator record

The operator's own bookkeeping, reported as-is. Accurate to what the merchant declared and the operator recorded.

  • Merchant identity and verification status
  • Physical and backed stock
  • Unit price in USDC
  • Inventory ledger entries
  • Product attributes, materials, images

Listing is open — any account can publish inventory, and stock counts are what the merchant declared, not what anyone counted. Verified merchants are labelled; everyone else shows as self-listed.

Not yet indexed

Fields the product roadmap includes but no system populates. Rendered as visible empty states, never estimated.

  • Current owner wallet and ENS
  • Transfer and price history
  • Agent view and purchase activity
  • Third-party authentication attestations
  • Merchant analytics and delivery ETA

If a value cannot be read, it says so. It does not infer, sample, or approximate.

Plain language

What we say, and what we don't.

Asserted: This item has a token on Base with the referenced contract and token ID.

Asserted: The operator recorded this many physical units and this many backed units.

Asserted: This merchant holds verified status with the operator.

Asserted: These inventory events were recorded, in this order, at these times.

Not asserted: This item is authentic, or has been authenticated by a third party.

Not asserted: The declared physical units actually exist. Listing is open, and nobody inspects a merchant's stock.

Not asserted: A specific wallet currently owns a claim on this item.

Not asserted: This item will be delivered within a stated timeframe.

Not asserted: This price reflects fair market value.

Portscan

An open explorer for tokenized physical inventory. It reports operator records and their on-chain references — it does not assert authenticity or ownership beyond what those records contain.
