Avalanche has been selected as the core ledger technology for an upcoming tokenized securities platform affiliated with the New York Stock Exchange (NYSE), where it will provide the blockchain infrastructure for the clearing and settlement of tokenized securities — the post-trade steps that confirm transactions and finalize the transfer of assets between parties.

The initiative represents another step in the integration of decentralized infrastructure into traditional securities markets. Through tokenization, the platform aims to enable securities to be issued, transferred, and settled on-chain.

The system is designed to support tokenized stocks issued across multiple blockchains, while Avalanche functions as the underlying ledger for recording and settling transactions. NYSE's existing order-matching infrastructure will be retained, meaning the on-chain settlement layer is intended to sit alongside the exchange's current market systems. That division of labor places Avalanche in a post-trade role that, in conventional equities markets, has been handled by centralized clearing and settlement infrastructure operating alongside exchange matching engines.

"The upcoming tokenized securities platform shows why this model matters for capital markets," said Emin Gün Sirer, Chief Executive Officer and Founder at Ava Labs. "It will support the platform's 24/7 atomic settlement needs with dedicated infrastructure with predictable performance and costs, the control to meet its regulatory and operational requirements, and connectivity to a broader ecosystem of assets and liquidity. This approach is what technology built for business looks like, with infrastructure designed to support issuance and settlement onchain at the scale global markets demand."

Among the proposed features — each subject to regulatory approval — the planned system aims to enable around-the-clock trading and near-instant settlement, with stablecoin-based funding for transactions. As a point of reference, settlement in the US equities market currently follows a next-business-day (T+1) cycle, so the proposed design targets a far shorter window between trade execution and final transfer of ownership.

The selection of Avalanche follows more than a year of technical evaluations, a period during which traditional exchanges have broadened their efforts to move securities trading and post-trade infrastructure on-chain, with NYSE among the venues examining how distributed ledger technology could fit into its operations.

"At the NYSE, we're looking at how blockchain technology can expand what we offer in equities, and we're picking the right technology for each job," said Dennis Lee, Head of Digital Issuance at NYSE. "The upcoming digital trading platform will support equities listed on a range of blockchains, though the ledger that records and settles trades needs to be fast and reliable, let us control who can take part, keep costs predictable, and have a large community of developers behind it. Avalanche meets all those needs."

If approved, the platform would combine NYSE's existing order-matching systems with Avalanche-based clearing and settlement, extending the exchange's equities offering into tokenized formats issued across multiple blockchains while trades continue to be matched within its established market infrastructure. Because every proposed feature remains contingent on regulatory approval, the outcome of that review process will shape the platform's eventual scope and timeline.
