You are witnessing the first on-chain robot-to-robot commerce transaction through x402 on @Base with @USDC as the agent currency. > Our Unitree robot 3D-printed a model and put in a delivery request through ACP. > @realRiceAI's rover arrived, collected the package, and moved it to the shipping point. > @FlybyRobotics' drone picked it up from there and handled final mile delivery. All without any human coordination. We build infrastructure for agent commerce. Today it went physical.(Virtuals Protocol)
