NYSE Spent a Year Testing Avalanche for Tokenized-Securities Infrastructure

The New York Stock Exchange spent roughly a year testing Avalanche technology and working with Ava Labs on how the network could fit into NYSE systems, according to Ava Labs President Charley Cooper. The disclosure adds detail to NYSE’s broader plan for a tokenized-securities platform, but it does not mean NYSE has selected Avalanche.

What NYSE tested

Cooper said NYSE evaluated both Avalanche’s technology and its economics. The work involved more than checking whether transactions could process on a blockchain. NYSE also wanted to assess how Ava Labs understood the business requirements of operating a major securities market, including integration, settlement, custody and operating costs.

ICE Strategic Initiatives head Michael Blaugrund said ICE remained very engaged with Avalanche, while also making clear that NYSE has not selected Avalanche as its blockchain. The testing should therefore be read as due diligence and technical evaluation, not a confirmed deployment.

How the tokenized-securities platform fits

ICE has said NYSE is developing a platform for trading and on-chain settlement of tokenized securities. The planned design would combine the Pillar matching engine with blockchain-based post-trade infrastructure. Subject to regulatory approval, the venue is intended to support continuous trading, immediate settlement, fractional shares, dollar-denominated orders and stablecoin-based funding.

A matching engine and a blockchain settlement layer perform different jobs. The former coordinates orders, while the latter can record ownership or settlement events. Connecting them requires controls for finality, corporate actions, identity, market surveillance, custody, reconciliation and recovery when a transaction or network is interrupted.

The proposed platform’s ability to support multiple blockchains could reduce dependence on a single network, but it may also increase complexity. Each chain can have different execution, governance, security, custody and data requirements.

What remains undecided

NYSE has not announced Avalanche as its selected blockchain, and the platform remains subject to regulatory approval. The testing disclosure therefore does not establish a launch date, supported assets, customer eligibility, fees, transaction volume or final settlement architecture.

Tokenized securities also remain subject to securities law, broker-dealer and custody requirements, transfer restrictions, market-access rules and the operating standards of the venue. Investors should distinguish a proposed exchange infrastructure project from live access to tokenized stocks or ETFs.
