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.
