Sphere · x402

Spatial social hubs where interaction is metered by proximity. 0.01 USDC unlocks 5 minutes of high-fidelity voice spatialization or private 'whisper zones' within VR environments. No subscriptions; users pay-per-presence via signature, enabling hyper-fluid pop-up events and sovereign social gating without the friction of pre-funding gas.

The primitive.

full primer →

Access to the XR social spaces engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so game designers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveXR social spaces suffer from 'the tragedy of the commons' or rigid subscriptions. x402 introduces a micro-tax on presence that funds the spatial compute and high-bandwidth assets in real-time. It turns every 'lobby' into a sovereign economical zone where creators are paid per attendee-minute.
