Escrow as the trust mechanism

Payment is held, auto-releases seven days after delivery is marked, and either side can open a dispute before it does. That combination is what lets two strangers do business.

Fees frozen per match

The service fee is snapshotted onto each match when it is agreed, so a later price change never reprices an existing deal.

Legal wording as a feature

Every screen says the platform is a connector, not a carrier, and that parcels are not insured, so expectations are set before any money moves.
