The Atlas of Agentic Stablecoin Compliance

The cartography
of compliance.

Mapping how stablecoin payments meet regulation — from protocol to policy. Two visual models, one classification legend, and the compliance-depth thesis that explains why stablechains exist.

Two Models, One Legend

How we map compliance

Stack Diagram Model 1 — Vertical. Shows compliance depth.

Compliance Depth

Where compliance lives in the stack

General-purpose chains bolt compliance on at L4–L5. Stablechains embed it at L2–L3. The depth matrix makes this thesis self-evident.

Layer General-Purpose L2 / Rollup Stablechain
L2 Consensus — — Permissioned validators, view keys, ZK-KYC
L3 Execution ERC-4337 (ETH only) ERC-4337, CCTP Enshrined DEX + policy, Transfer Hooks
L4 Middleware Chainalysis, Circle API Chainalysis, ACK-ID, Circle API Full coverage
L5 Application Wallet KYC, SAR filing Wallet KYC, SAR filing Wallet KYC, SAR filing

Protocols

The agentic payment stack

ACK-ID Production

Agent Commerce Kit — Identity

W3C DID + Verifiable Credential framework for autonomous agent identity. Establishes principal→agent delegation chains with cryptographic proof.

Skills Ecosystem

The compliance interoperability layer for fintech AI skills

Four published skills ecosystems tell developers how to write stablecoin code. Atlas maps where that code lives in compliance architecture — which Stack layer, which STP stage, which checkpoint type, and whether it's code-enforced or policy-enforced.
