Blockchain Steps Into Wall Street Clearing
Paxos Securities Settlement Company, a subsidiary of Paxos, has received full registration from the U.S. Securities and Exchange Commission (SEC) to operate as a clearing agency for U.S. equities.
The registration falls under Section 17A of the Securities Exchange Act and follows a multi-year process that began with a no-action letter from the SEC in October 2019. That letter allowed Paxos to pilot its blockchain-based settlement service, which officially launched in February 2020 with participation from major financial institutions such as Bank of America and Credit Suisse.
Seven-Year Push Nets Paxos Win
The path to SEC approval was not short. Over seven years, Paxos worked closely with regulators, starting with the 2019 no-action relief that enabled its initial pilot program. The company’s journey included live daily settlements of U.S. equities under regulatory oversight, and by 2022, it had partnered with State Street to demonstrate same-day (T+0) settlement on blockchain rails—a significant acceleration compared to legacy systems.
The SEC communicated its approval to Paxos on March 11, 2024, after years of regulatory engagement.
On paper, this is an operational milestone; but it also represents a regulatory experiment that could reshape how equity trades are finalized in America’s largest markets. Notably, the U.S. equity markets themselves shifted to T+1 (one business day) settlement in 2024, while Paxos’ technology has already proven capable of achieving T+0 speeds in controlled pilots.

First Crypto Firm Joins Settlement Ranks
Paxos is now the only blockchain-native firm registered as a clearing agency under the SEC.
This registration allows Paxos to bundle regulated stock clearing with its existing infrastructure tools already used by major clients like PayPal and Mastercard. According to coindesk.com, Paxos’ central clearinghouse designation means it can offer both digital asset services—such as issuing PayPal USD (PYUSD) and Pax Gold (PAXG)—and traditional equity settlement under one regulatory roof.
Traditional Stocks Meet Digital Rails
The SEC’s approval comes at a time when traditional finance is increasingly intersecting with digital assets. In 2023, however, the regulator sent Paxos a Wells Notice regarding its role in issuing Binance USD (BUSD), which the SEC considered an unregistered security. Despite this scrutiny, Paxos’ successful registration as a clearing agency signals regulatory willingness to integrate blockchain solutions into established market frameworks—at least for now.
While some may expect immediate transformation of stock trading practices, it’s unclear how quickly or widely other market participants will adopt blockchain-based clearing for equities beyond pilot projects.
What This Means for Stock Trades
For investors and brokers alike, the implications are concrete: faster settlement times could reduce counterparty risk and free up capital more quickly than legacy systems allow. During its pilot with State Street in 2022, Paxos achieved T+0 settlement—same-day completion—compared to the industry standard of T+1 adopted nationwide in 2024. This technical capability could eventually lead to broader efficiency gains if adopted at scale.
Still, ongoing regulatory requirements mean that Paxos’ current registration is described as temporary while it continues to meet compliance standards set by the SEC. The company also holds licenses from other major regulators: the Office of the Comptroller of the Currency (OCC) in the U.S., Singapore's MAS, and Europe's FIN-FSA—positioning it for cross-border expansion if regulations align.
For now, Wall Street’s core processes remain largely unchanged—but with this approval, blockchain has moved one step closer to mainstream adoption in U.S. equity markets.
Key signals ahead
If Paxos Securities Settlement Company meets the ongoing regulatory requirements tied to its temporary SEC registration communicated on March 11, it can continue providing clearing and settlement services as a central securities depository in the U.S.; failure to comply would immediately jeopardize its ability to operate under this status.
