The US SEC has accepted the NYSE's new regulations, proposing to introduce a tokenized securities trading mechanism to support on-chain settlement

The SEC released a document (34-105260) disclosing the rule change application submitted by the NYSE, intending to formally introduce a framework for trading tokenized securities.

According to the proposal, the NYSE plans to add Rule 7.5, allowing eligible securities to be traded and settled in a blockchain-based tokenized form in addition to traditional forms. The relevant arrangements will operate under the DTC pilot program. The core mechanisms include: tokenized securities and traditional stocks will share the same trading code (CUSIP) and rights structure, and will be fully interchangeable; in the matching system, tokenized and traditional securities will have the same execution priority, and the order of transactions will not be affected by the different forms; trading participants can choose to settle and clear in an on-chain form through a tokenization flag, with specific processing carried out by custodians. Additionally, the NYSE also plans to simultaneously modify order sorting, routing, and clearing rules to accommodate the trading process of tokenized securities, ensuring seamless integration with the existing market structure.

From a market perspective, this proposal signifies that traditional U.S. securities exchanges are officially exploring the introduction of blockchain technology into the core trading and settlement systems. If approved, it could become an important milestone for on-chain securities entering mainstream financial infrastructure.
