Taxi Handover
Patty steps out of her apartment in Bandra. She’s late for a meeting in Andheri. She doesn’t open an app — her phone agent already knows her calendar. It broadcasts an RFQ to the local ride network. Sai, three blocks away, bids: 3.50 base + 0.85 per kilometer. Patty’s agent checks his reputation score, locks 7.78 USDC into escrow (fare + 10% buffer), and confirms. Sai’s car pulls up. GPS verifies pickup. Twenty minutes later, GPS verifies dropoff. Escrow releases. Sai gets paid. The whole transaction — discovery, bidding, payment, settlement — happened between two phones, with zero human input.
A full marketplace flow: RFQ broadcast, competitive bidding, escrow lock, GPS verification, and trustless settlement. Every switchboard module in one ride.
