Atomic DvP is not a technology choice in isolation. It sits at the intersection of four converging regulatory and standards frameworks — each actively shaping how settlement finality, tokenized asset issuance, and cross-border payment infrastructure must perform.
The Markets in Crypto-Assets Regulation establishes the stablecoin framework that functions as the settlement currency layer for atomic DvP in European capital markets. MiCA-compliant asset-referenced tokens and e-money tokens issued by authorized credit institutions and payment institutions are the payment leg candidates for EU-jurisdictional atomic settlement. The regulation's reserve, redemption, and issuance requirements provide the legal certainty that institutional counterparties require before accepting a stablecoin as final settlement consideration.
The EU DLT Pilot Regime operates in parallel, explicitly authorizing DLT-based trading and settlement systems within defined thresholds. 21X in Frankfurt is the first operational DLT Multilateral Trading Facility under the Pilot Regime — running an on-chain central limit order book with atomic DvP in MiCAR-compliant stablecoins as the native settlement mechanism. The combination of MiCA (defining the permissible settlement currency) and the DLT Pilot Regime (authorizing the settlement infrastructure) creates a functioning legal framework for atomic DvP in EU-regulated capital markets. This is no longer a theoretical architecture: it is operating.
The GENIUS Act conditionally approved five national trust bank charters for digital asset infrastructure as of December 2025 — BitGo, Circle, Fidelity Digital Assets, Paxos, and Ripple — moving stablecoin issuance and digital asset custody inside the federal banking perimeter. This structural shift is significant for atomic DvP: stablecoins issued by federally chartered institutions carry a materially different counterparty risk profile than those issued by non-bank entities, and their use as the payment leg in atomic settlement is substantially more defensible from a regulatory capital and operational risk standpoint.
The Federal Reserve's RTGS infrastructure — FedNow for instant retail payments and Fedwire for wholesale — defines the existing payment rail against which atomic DvP payment legs must interoperate. The operational question for US market participants is not whether atomic DvP is technically possible, but whether the payment leg can connect to central bank money in a form that satisfies settlement finality requirements under existing Federal Reserve operational frameworks. FedNow's 24/7 availability and Fedwire's existing RTGS architecture each represent potential integration points for tokenized asset settlement workflows.
The Committee on Payments and Market Infrastructures Principles for Financial Market Infrastructures — PFMI — are the global standards that govern settlement finality, default management, liquidity risk, and operational resilience for systemically important payment systems, central securities depositories, and central counterparties. Any atomic DvP infrastructure operating at institutional scale must satisfy the same PFMI requirements as traditional financial market infrastructures: irrevocable settlement finality, adequate liquidity resources to complete settlement in stress scenarios, and default management procedures that do not depend on the creditworthiness of any single participant.
DLT-based settlement systems are not exempt from PFMI compliance on the basis of technical novelty. The BIS Innovation Hub's Project Meridian and Project Agorá work has consistently engaged with the PFMI framework as the applicable standard — testing whether DLT-based atomic settlement can satisfy the same legal certainty, finality, and default management requirements as conventional FMIs. The emerging consensus from BIS research is that it can, provided that the legal treatment of on-chain finality is aligned with the applicable PFMI framework in each jurisdiction. This legal alignment, not the technical implementation, is the primary remaining barrier.
The International Organization of Securities Commissions and the Global Financial Markets Association have each published frameworks addressing DLT in capital markets that explicitly call for atomic DvP as a settlement standard. The 2025 GFMA report on DLT in capital markets stated directly that the industry should "integrate tokenized deposits and stablecoins into settlement workflows, enabling atomic DvP and programmable payments." This represents the capital markets industry's own roadmap, articulated by the organization representing the world's largest financial institutions — not a regulatory mandate, but an industry-wide commitment that shapes technology procurement, infrastructure investment, and vendor evaluation across the institutions that comprise the global capital markets.
IOSCO's broader work on crypto-asset markets and the regulation of DLT-based trading and settlement systems establishes the securities regulatory framework within which atomic DvP infrastructure must operate across jurisdictions. For post-trade infrastructure vendors, capital markets technologists, and DLT platform providers evaluating atomic DvP deployment, the GFMA roadmap and IOSCO standards together define the institutional expectations that any production system must satisfy.
