Marketplace trust
Evidence
over theatre.
Trust comes from clear sources, private boundaries, reviewable state and safer behaviour—not a decorative shield icon.
Image sources
Know what you are seeing.
Seller photos remain the highest-priority representation of a listing. Official catalogue media and synthetic catalogue decoration remain separate sources and are not presented as seller-supplied evidence.
Condition
Seller declarations stay attached.
Condition answers, material disclosures and listing photos remain connected to the physical item so a buyer can inspect what the seller actually declared.
Value language
A declaration is not a valuation.
Seller asks, cash components and reference context remain distinct. Buyers should inspect an item and conduct independent research before agreeing to a trade.
Identity & privacy
Public social identity is separated from sensitive data.
Profiles, handles, follows and broad region support discovery. Exact addresses, private identity evidence, account controls and sensitive fulfilment context belong behind scoped authorisation.
Negotiation
The agreement stays legible.
Offers and counters carry explicit items and amounts. Every counter creates a new version, and invalid state transitions are rejected instead of silently rewriting the agreement.
Community safety
Public places, clear exits and no pressure.
For local exchanges, prefer busy staffed locations, tell someone where you are going, inspect before confirming and walk away if anything feels wrong. Community events are labelled as community-created, not official Trading Block events.
Public access
Web accounts open only after production authentication, private storage, realtime transport and operational safeguards are configured. The public site does not route private trades through a temporary development database.
