Sphere · Metered

Spatial social hubs where interaction is metered by proximity. 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. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.

Kernel
an HTTP 402 challenge in front of exactly one valuable operation — an export, a render, a full-resolution download — where each unlock is a single USDC payment bound to its settlement tx
Drives the UI as
a locked panel that states its price before you sign, plus an 'unlocks bought / used' counter beside the released payload
