A major Wall Street exchange operator is building infrastructure to bring securities trading onto the blockchain. The initiative centers on tokenized assets paired with on-chain settlement infrastructure—still awaiting regulatory greenlight before launch. Once approved, the platform promises three game-changers: round-the-clock market access (goodbye 9:30-4 PM windows), fractional ownership enabling micro-investments, and settlement completing in seconds rather than days. This move signals the broader institutional shift toward decentralized finance mechanics applied to traditional asset classes. The regulatory pathway remains crucial; approval would mark a watershed moment for crypto-native infrastructure gaining Wall Street credibility.
