StablecoinAtlas

Physical. Logical. Visual.

Every system has three representations.

Most diagrams pick one and hope it’s enough.

Physical shows where things run — the actual servers, edge regions, and chains. Logical shows how they relate — data flows, protocol sequences, trust boundaries. Visual makes both legible — the designed artifact a team can actually reason from.

StablecoinAtlas maps the infrastructure layer of the stablecoin economy across all three.

Physical

Topology

Where things are deployed. Cloudflare edge, Base L2, CDP facilitator, USDC contract addresses. The actual infrastructure under the abstractions.

Logical

Flow

How value and data move. x402 handshake sequences, AP2 mandate stacks, KYA credential propagation. Protocol relationships made precise.

Visual

Map

Beck-style transit diagrams. Four protocol lines. Every interchange, every station. The form that turns protocol specs into something a team can navigate.

Diagrams in progress.

The first three diagrams ship with POC 3 of the Stable402 build sequence.

Agentic Payments Transit Map

Four protocol lines — x402, ACP, AP2, UCP — as Beck-style stations. Every interchange between protocols visualised. Clickable stations link to live implementations.
