How It Works

Building trust without trusting the counterparty

01

Route-Based Matching

Match seekers with travelers already traveling specific routes (international, train, car, or same-city). Leverage existing human motion.

02

Cryptographic Proof Chains

Combine independent signals (purchase proof, location check-ins, challenge-bound video, and witness attestations) into a tamper-evident graph.

03

Venue Anchor Nodes

Cafes, hotels, and local merchants act as physical co-presence check-in points, running rotating QR challenges and witnessing handoffs.

🔒

Dual-Collateral Escrow

Seekers lock USDC in escrow, and travelers lock collateral bonds. This alignment of economic incentives prevents griefing and fraud.

On-Chain Settlement

The Handoff Protocol

From escrow proposal to verified release

Request & Escrow

Seeker creates an order on-chain, deposits item value, fulfillment fees, and a requester bond in secure Solana escrow.

Accept & Collateral

A traveler accepts the route-bound request and posts a collateral bond, confirming their role as a verified shopper.

Evidence Progression

Traveler purchases the item and uploads purchase/possession proofs. The app checks in at travel checkpoints to populate the evidence graph.

Verified Settlement

Requester and traveler meet at a Venue Node. Staff witness the handoff. Escrow is released, bonds returned, and fee distributed.

The protocol is a system for coordinating, verifying, and settling real-world exchanges between parties that do not fully trust each other. Delivery is the wedge. The platform is physical trust infrastructure.
