A contractual digital protocol
The current product focuses on validating demand and making each custody change visible inside the deal workflow.
- Digital cargo manifest
- Deal chat and mutual confirmation
- Pickup and delivery status trail
Open inspection protocol
See it. Match it. Record it.
The core safety rule is simple: never carry a sealed unknown item. The sender opens it, the traveler checks it against the manifest, and both sides record the handoff.

Four checkpoints, one shared record.
Each checkpoint reduces ambiguity by making the package contents and custody changes explicit to both participants.
Open handoff
The sender presents the item unsealed at the agreed gate, station, or meeting point.
Visual check
The traveler compares the actual contents, quantity, and condition with the digital manifest.
Mutual record
Both sides confirm the match in the deal chat and agree on the package identifier.
Status trail
Pickup and delivery confirmations create the current end-to-end responsibility record.
Practice the handoff check.
Use this guide before confirming pickup in an actual deal.

When the route changes
