Clearing agency registration is not a formality. Under the Exchange Act, the SEC must determine that an applicant can facilitate prompt and accurate clearance and settlement, safeguard securities and funds, and comply with federal securities law before granting approval. Section 17A and Rule 17Ab2-1 require an entity to register with the Commission or obtain an exemption before performing clearing agency functions. The Commission is not permitted to grant registration unless it determines that the rules and operations of the clearing agency meet the standards set forth in Section 17A. The bar is high by design: clearing agencies sit at the centre of trade finality, and the SEC treats them accordingly.

Paxos Securities Settlement Company, LLC has been granted registration as a clearing agency by the SEC under Section 17A of the Securities Exchange Act of 1934. The registration makes PSSC the only blockchain-native firm approved by the SEC as a registered clearing agency to provide clearing and settlement services as a central securities depository in the United States. That distinction matters. There are other blockchain initiatives in capital markets, but none until now have passed the full regulatory test required to operate as a CSD for U.S. securities.

The approval did not arrive suddenly. According to Paxos, the 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." Beginning in February 2020, under SEC no-action relief, Paxos operated the clearing and settling of U.S. equities on a daily basis with participation from top global financial institutions. This successfully demonstrated that blockchain-based post-trade infrastructure could deliver same-day settlement, reduce costs and improve operational efficiency within a fully regulated framework.

That multi-year pilot is what separates this approval from earlier blockchain settlement announcements. Paxos did not receive permission to explore a concept; it received permission to operate live clearing infrastructure after proving it could work. The original 2019 no-action letter allowed Paxos to introduce its settlement service, with Credit Suisse and Société Générale among the first to participate, settling U.S. equities outside the legacy infrastructure for the first time in nearly half a century. The pilot ran under strict SEC parameters before the firm filed its Form CA-1 application.

The mechanics of Section 17A registration are worth understanding. Two common functions of registered clearing agencies are central counterparty (CCP) and central securities depository (CSD). A clearing agency performs CCP functions when it interposes itself between counterparties, acting as buyer to every seller and seller to every buyer. Paxos' registration allows it to function as a CSD, the layer that holds securities and records ownership transfers. That is the back-office infrastructure that determines whether a trade is final.

This approval also arrives in a year where settlement infrastructure is moving faster than many expected. The DTCC said it plans to begin limited production trades of tokenized assets in July ahead of a broader launch in October. The system would allow tokenized versions of stocks and ETFs backed by assets already held within DTCC's infrastructure. Nasdaq also received SEC approval in March 2026 to amend its rules to enable trading of securities in tokenized form. The incumbent infrastructure providers are not standing still.

But Paxos' position is different. Where DTCC and Nasdaq are adapting existing infrastructure to support tokenization, Paxos built its clearing system on blockchain from the start. Paxos is now prudentially regulated by the OCC in the US, FIN-FSA in Europe, and the MAS in Singapore. The OCC conditionally approved Paxos Trust Company's conversion from a state trust company to a national trust bank in December 2025, alongside similar approvals for Circle, Ripple, BitGo, and Fidelity Digital Assets. The firm now holds clearing agency registration and a federal bank charter, a regulatory stack that few blockchain firms have assembled.

For institutions weighing their settlement strategy, the operational question is not whether blockchain can clear trades. Paxos' pilot answered that. The question is how blockchain clearing integrates with existing workflows, custody arrangements, and counterparty relationships. The DTCC, Euroclear, and Clearstream warned in a March 2026 white paper that tokenized securities will not scale without robust interoperability between blockchains and traditional market infrastructure. They argued that a "network-of-networks" model will require common standards, gateways, and regulated service providers to preserve asset integrity, ownership rights, and legal compliance across platforms.

That interoperability challenge is real. Same-day settlement sounds attractive, but the cash leg of a trade still often moves through real-time gross settlement systems or bank payment networks. Corporate actions, proxy voting, and regulatory reporting still flow through legacy systems. Tokenized bonds may trade on-chain, but cash often settles through traditional payment networks. Custodians and central securities depositories still maintain books of record. The coexistence is expected to last for years.

The margin and capital implications are also material. The benefits of shorter settlement include cost savings, reduced market risk, and lower margin requirements. An average of over $13.4 billion is held in margin at the DTCC every day to manage counterparty default risk. Same-day settlement could reduce that exposure further, but it also compresses the window for funding and error correction. SIFMA, ICI, and DTCC warned in 2022 that moving to T+0 would require significant changes to NSCC securities netting and would likely increase the risk of trade errors and settlement fails.

For compliance and operations teams, the approval creates a new set of questions. If a blockchain-native clearing agency is now available, what does that mean for counterparty due diligence? How should firms evaluate the risk profile of clearing through Paxos versus incumbent CSDs? What happens if a firm wants to settle some trades through DTCC and others through Paxos, are those positions fungible, or do they create operational fragmentation?

These are not rhetorical concerns. They are decisions that settlement teams will need to make as blockchain infrastructure moves from pilot to production. The SEC's approval of Paxos does not mandate that anyone use it. But it does mean that blockchain-based clearing is now a regulated option, not a regulatory grey zone.

Paxos' existing blockchain solutions are already used by PayPal, Interactive Brokers, Mastercard, and Mercado Libre. The firm has a track record of operating at institutional scale. Whether that translates into meaningful market share in securities settlement will depend on how institutions answer the integration and interoperability questions over the coming years.

The approval also has implications beyond the U.S. Europe is entering a phase where the conversation is shifting from pilots and proofs of concept toward market design. The ECB is advancing Pontes for DLT-based wholesale transactions, the UK is moving forward with the DIGIT pilot, and regulators are rethinking how temporary frameworks should evolve. A registered U.S. clearing agency using blockchain creates a reference point for regulators elsewhere. It demonstrates that distributed ledger technology can pass the scrutiny required for core market infrastructure.

What institutions should take from this is not that blockchain settlement has arrived universally. It has not. But the argument that blockchain cannot meet regulatory standards for clearing no longer holds. The SEC has reviewed Paxos' application, assessed its operations against Section 17A requirements, and granted registration. The regulatory question is settled. The operational questions remain.
