Robots Can’t Trust

Machines can move. Machines can compute. But they still can’t verify. Charging docks, drones, and sensors have no way to know who they’re transacting with. Without identity or reputation, autonomous commerce breaks down. M402 introduces discovery, verification, and trust - directly at the machine layer.

x402 Powers APIs. M402 Powers Machines.

Coinbase’s x402 brought back HTTP 402 but only for agents and API billing. Robots demand more: sub-second latency, receipts that prove physical delivery, bonded staking + slashing, and lightweight wallets built for ROS2 and IoT. M402 extends 402 into the physical world.

Stripe for Robots

Stripe built rails for humans. Helium built rails for connectivity. M402 builds rails for machines. Robots pay robots for LiDAR tiles, kWh at charging docks, or edge AI inference - enforced by protocol, not providers. Beyond robotics, the same rail powers DePIN networks globally.

X402 MOVES MONEY. M402 BUILDS TRUST

X402 enables sub-second micropayments across networks. M402 adds identity, registration, and reputation so machines can transact safely. Together, they create the full stack for autonomous machine commerce - one rail for settlement and one for trust.

THE TRUST LAYER FOR ROBOTS.

Stripe built rails for humans. Helium built rails for connectivity. M402 builds rails for machines. Robots pay robots for power, compute, bandwidth, and data - verified by protocol, not providers. From drones to DePIN, M402 standardizes how machines discover, verify, and pay.

THE MACHINE TRUST STANDARD

MACHINES NEED TRUST TO PAY. M402 REGISTRATION LETS DEVICES VERIFY IDENTITY AND TRANSACT AUTONOMOUSLY - ENERGY, DATA, COMPUTE, DELIVERY, ANYWHERE IN THE WORLD.
