7 rails · 53 paths · 3+5 shape system

Query any stablecoin payment path. See every checkpoint that fires.

Abstract. Three checkpoint shapes (octagon = gate, circle = monitor, diamond = obligation) plus five infrastructure glyphs. Pick a chain, jurisdiction, amount, and rail; the engine resolves every checkpoint, threshold, and vendor that fires across the eight Stable STP stages.

Silhouette A — 3+5 shape system

What it is. Three compliance checkpoint shapes — octagon for gates, circle for monitors, diamond for obligations — plus five infrastructure glyphs that anchor the stations along the spine.

How to read it. Enforcement rings encode code-enforced (solid) vs. policy-enforced (dashed) on every station. Pick a rail at top to see how the shape system applies across that compliance posture.

How to read this diagram

Each station on the rail represents a compliance or infrastructure event in the Agentic x402 purchase path. Hover any station to inspect it. The shape tells you what kind of event it is. The ring tells you how it's enforced.

STP Path Engine

What it is. Interactive compliance path resolver. Pick parameters; the engine resolves the path template and lays out every checkpoint across the eight stages.

Try it. Switch chains and watch how the ERC-3643 identity gate or the OFAC screen drops in or out. Switch jurisdictions to see how the EU MiCA path diverges from the US GENIUS Act path.
