Reading the Matrix

Each row is a compliance domain — a category of regulatory obligation that may or may not apply to a given payment flow. Each column is a rail — one of seven transaction lifecycle categories. A lit cell means at least one path on that rail triggers checkpoints in that domain.

Five domains fire universally across all seven rails: C1 Identity & Due Diligence, C2 Sanctions, C8 Operational Resilience, C11 Recordkeeping, and C12 Audit & Attestation. These are the compliance floor — no stablecoin payment avoids them.

The gaps are as informative as the coverage. C4 Fraud fires only on Retail and DeFi — the rails with direct consumer exposure. C15 Dispute Resolution concentrates on Wholesale, Securities, and Post-Trade — institutional rails with contractual counterparties. The matrix makes these structural patterns visible at a glance.
