Paxos Secures Landmark SEC Approval for Blockchain Clearing

NEW YORK, NY – May 28, 2026 – In a decision poised to reshape the bedrock of U.S. financial markets, the Securities and Exchange Commission (SEC) has granted full clearing agency registration to Paxos Securities Settlement Company (PSSC). The move makes the Paxos subsidiary the first and only blockchain-native firm authorized to operate as a central securities depository, clearing and settling stock trades in the United States.

This landmark approval represents the culmination of a seven-year dialogue with regulators and signals a major milestone in the convergence of traditional capital markets with emergent blockchain technology. For decades, the post-trade landscape has been dominated by a handful of incumbents. Now, a regulated, technology-driven challenger has officially entered the arena, promising to bring unprecedented speed and efficiency to the multi-trillion dollar plumbing of Wall Street.

A Seven-Year Regulatory Journey

The SEC's decision was not made overnight. It follows a meticulous, multi-year process that tested the capabilities and resilience of Paxos's blockchain-based infrastructure within a strictly controlled environment.

"Our clearing agency registration is the result of seven years of work with the SEC, beginning with our No-Action Letter in 2019 and the settlement pilot we operated with some of the world's largest and most sophisticated financial institutions," said Charles Cascarilla, CEO and Co-Founder of Paxos, in a statement.

That 2019 No-Action Letter was a critical first step, creating a regulatory sandbox for the company to test its "Paxos Settlement Service" in a live production environment. Beginning in February 2020, the pilot program saw major global banks, including Credit Suisse and Société Générale, use the permissioned blockchain platform to settle U.S. listed equity trades.

The pilot successfully demonstrated that blockchain technology could not only function reliably within the stringent confines of U.S. securities law but could also deliver significant benefits. Participants were able to achieve same-day settlement, a dramatic improvement over the current two-day standard, while also realizing meaningful reductions in operational costs and fees. This real-world validation provided the SEC with the necessary data and confidence to grant PSSC full registration under Section 17A of the Securities Exchange Act of 1934.

Disrupting the Post-Trade Monopoly

PSSC's entry as a registered clearing agency introduces a new paradigm into a market long dominated by The Depository Trust & Clearing Corporation (DTCC). For nearly 50 years, the DTCC has served as the central infrastructure for clearing, settlement, and data management for the vast majority of U.S. securities transactions. However, its legacy systems, which rely on batch processing and multiple intermediaries, are often cited as a source of inefficiency and risk.

The financial services industry spends an estimated $133 billion annually on post-trade operations, and even minor failure rates can cost the industry billions. Blockchain technology promises to overhaul this model. By creating a single, immutable ledger shared between parties, it can eliminate the need for constant reconciliation and reduce the role of intermediaries. Accenture has estimated that blockchain could slash operational costs for trade support, clearance, and settlement by as much as 50%.

The incumbent is not standing still, however. Recognizing the disruptive potential of distributed ledger technology (DLT), the DTCC has been actively developing its own capabilities. Its Project Ion, a DLT-based settlement platform, now runs in parallel with its classic systems and processes over 100,000 transactions daily. Following its 2023 acquisition of digital asset firm Securrency, the DTCC is signaling a clear strategy to evolve rather than be replaced.

PSSC's approval, therefore, doesn't just introduce a new player; it validates a new technology and intensifies the race to modernize the core infrastructure of capital markets. The competition is no longer just between firms, but between technological architectures.

The Promise of T+0 Settlement

The most transformative advantage offered by blockchain-native settlement is the potential to move from a two-day settlement cycle (T+2) to same-day or even real-time settlement (T+0). In the current T+2 system, capital and securities are locked up for two business days after a trade is executed, exposing both parties to counterparty and market risk during that period.

A blockchain-based system facilitates near-instantaneous exchange of assets and cash, a process known as atomic settlement. This drastically reduces risk and frees up trillions of dollars in liquidity that is otherwise trapped in the settlement process. Beyond risk and liquidity, the operational benefits are substantial. Smart contracts—self-executing code on the blockchain—can automate complex processes like dividend payments and corporate actions, reducing the potential for costly human errors and manual interventions.

This enhanced transparency and automation create a more resilient and auditable system. Every transaction is cryptographically secured and recorded on an immutable ledger, providing a single source of truth for all participants and regulators.

While the potential is immense, challenges to widespread adoption remain. Integrating new DLT platforms with decades-old legacy systems at financial institutions presents a significant technical hurdle. Furthermore, ensuring these new networks can scale to handle the massive transaction volumes of the U.S. equity market without sacrificing speed or security is a critical test that PSSC will now face on a much larger scale.

A New Precedent for Digital Assets Regulation

The SEC's greenlighting of PSSC is more than an isolated approval; it represents a significant evolution in the regulatory posture toward digital assets and DLT. By moving a blockchain-based system from a limited pilot to a fully registered piece of national financial infrastructure, the agency is setting a powerful precedent. It demonstrates a pathway for innovators to bring novel technology into the heart of capital markets, provided they are willing to engage in long-term, transparent collaboration with regulators.

This move aligns with a broader, albeit cautious, trend toward establishing clearer rules for the digital asset space. Just this year, the SEC and the Commodity Futures Trading Commission (CFTC) issued a joint interpretation to help classify different types of crypto assets, aiming to reduce regulatory ambiguity. Legislative proposals like the CLARITY Act are also being debated in Congress, seeking to create a comprehensive legal framework for the industry.

PSSC's registration as a clearing agency proves that blockchain is no longer confined to the speculative fringes of finance. It is now a recognized and regulated technology capable of supporting the most critical functions of the U.S. financial system, potentially paving the way for further integration of tokenized assets and DLT-based innovations in the years to come.
