For decades, if you wanted to clear and settle a securities trade in the US, your business ultimately flowed through one place: the Depository Trust & Clearing Corporation. That cozy arrangement just got its first real competitor from an unexpected corner of finance.

Paxos Securities Settlement Company, a subsidiary of Paxos, has been registered by the SEC as a clearing agency under Section 17A of the Securities Exchange Act of 1934. It is the first and only blockchain-native entity in the US to hold that designation.

What actually happened, and why it matters

The SEC granted PSSC registration as a central securities depository, meaning it can clear and settle eligible securities transactions using blockchain infrastructure rather than the legacy plumbing that has underpinned American capital markets for half a century.

When you buy a stock, there’s a behind-the-scenes process where ownership actually changes hands and money moves between accounts. That process currently takes one business day (known as T+1, which itself was only recently shortened from T+2). Paxos’s blockchain-based system could potentially compress that timeline all the way down to T+0, meaning trades settle on the same day they’re executed.

Paxos filed its formal application for registration in July 2025, but the groundwork stretches back years. The company secured a no-action letter from the SEC in October 2019. That led to a pilot program launched in October 2021 involving major financial institutions including Credit Suisse and Societe Generale, both of which tested the blockchain-based settlement system before the SEC was willing to grant full registration.

A slow burn, not a sudden move

Paxos received a limited-purpose trust charter from the New York Department of Financial Services back in 2015, establishing itself early as a compliance-first blockchain company. It later picked up a payments license from the Monetary Authority of Singapore in 2022, extending its regulatory footprint internationally.

No immediate impact on token prices or crypto trading volumes was reported following the announcement. Paxos isn’t building a new exchange or listing new assets. It’s rebuilding the pipes that sit behind existing markets.

What this means for investors

The most direct beneficiaries in the near term are broker-dealers and institutional players who stand to save on the capital requirements associated with longer settlement windows. When a trade takes a full day to settle, both sides of the transaction need to hold collateral against the risk that the other party defaults before settlement completes. Shrink that window to hours or minutes, and the collateral requirements shrink with it.
