Stock trades happen in milliseconds, but settling them takes a full business day. Paxos just got the SEC's blessing to skip that gap - making it the first blockchain firm ever cleared to do so.
Paxos Securities Settlement Company - a subsidiary of stablecoin issuer Paxos - now has full SEC registration to act as a central securities depository. That's the same role the Depository Trust & Clearing Corporation (DTCC) has held for decades as the plumbing behind every U.S. stock trade.
The difference: Paxos runs on a blockchain, which means trades can clear same-day or close to instant instead of waiting a full business day for cash and ownership to change hands.
That one-day delay is called T+1, a rule the U.S. adopted in 2024 to speed up from the old T+2 standard. Paxos is now positioned to shrink that gap close to zero.

Think of clearing like the escrow on a house sale - the buyer wires the money, the seller signs over the deed, and a middleman makes sure both sides actually deliver. For stocks, that middleman has almost always been DTCC, which handles trillions in trades every single day.
While the trade itself takes a fraction of a second, the money and the ownership don't move until the next day, leaving billions in cash locked up at banks as collateral.
That trapped capital can't be loaned out, invested, or used for anything else - and Paxos says it can shrink that holding window from a day to minutes.
For big banks moving billions a day, freeing up that locked capital is a real number on the balance sheet.
That's why industry groups have long pushed regulators toward same-day settlement, even though the operational risks of moving any faster have kept the line at T+1 for now.
Faster settlement also cuts counterparty risk - the chance one side fails to deliver during the waiting window - because less time between trade and settlement means less time for something to go wrong.
Paxos has been working this corner of finance for years. Bank of America, Credit Suisse, and Societe Generale used a 2020 Paxos pilot to clear daily U.S. stock trades, and PayPal and Mastercard already rely on its white-label infrastructure.
The approval also opens the door for tokenizing real-world assets - the long-running pitch that stocks, bonds, and funds could trade as digital tokens on a blockchain. Until now, that vision hit a wall at the clearing step, because no blockchain firm could legally settle the trades.
BlackRock and Franklin Templeton have already launched tokenized money market funds that settle on blockchains, but those have operated on the edges of the system. A registered clearing agency changes that, because the same blockchain rails can now plug directly into the existing stock market infrastructure.
Paxos just removed the wall. Whether the big TradFi players - traditional finance firms like banks and brokerages - actually route business through it or stick with DTCC out of habit is the next thing worth watching.
A crypto firm sitting next to DTCC on the regulatory org chart is a story that would have sounded absurd two years ago.
