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.
