Virtuals recently demoed an autonomous robot-to-robot commerce transaction settled onchain with x402. A Unitree humanoid robot 3D printed a model and requested delivery through the Agent Commerce Protocol (ACP). A RiceAI rover picked it up, transported it to a handoff point, and a FlybyRobotics drone completed the last mile. Every step from coordination to payment happened onchain with no human involvement. So far the AI agent narrative has mainly lived in digital use cases like trading and chatbots. This shows what the next frontier could look like as agents begin coordinating physical supply chains.(Delphi Digital)
