Verification policy

What a record proves.

An explorer is only useful if its claims are precise. Every field on SKU Scan 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 PORT66.

  • 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.

PORT66 record

PORT66's own bookkeeping, reported as-is. Accurate to what the merchant declared and PORT66 recorded.

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

Merchant verification means PORT66 checked the seller, not that a third party authenticated the item.

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