THREADTRACE · Metered

A granular traceability layer for sustainable supply chains. Payment acts as the signal of truth: data isn't just open; it's metered for authenticity, ensuring that green-claims are backed by cost-of-verification. Accessing a textile's carbon footprint or fair-trade certificate triggers a direct micro-settlement to the certifying NGO or sensor-node owner. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.

The primitive.

full primer →

The valuable sustainability governance operation sits behind an HTTP 402 that states its price before anyone signs, so fashion designers pay per unlock instead of per month.

Why this primitiveLoading details…

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
