Ondo Finance integrates Chainlink as the official oracle for SPYon, QQQon, and TSLAon on Ethereum, paving the way for Tokenize shares to become collateral in DeFi.
A significant step forward in bridging the gap between traditional and decentralized finance was marked when Ondo Finance officially activated on- chain price data sources for Tokenize US stocks.
According to an announcement on Wednesday, the Ondo Global Markets platform has integrated Chainlink as its official data oracle, providing real-time valuations for its first three products: SPYon representing the SPDR S&P 500 ETF, QQQon representing the Invesco QQQ ETF, and TSLAon representing Tesla stock.
This move addresses a long-standing limitation of the Tokenized Stocks market, which is primarily held for price exposure but has not been widely accepted as collateral in decentralized finance protocols.
Data sources are now active on Euler, where users can deposit Tokenize shares as collateral to borrow stablecoins, marking a shift from passive holding to active application within the DeFi ecosystem.
Pricing infrastructure for hybrid assets
This integration provides on- chain pricing data for Tokenize assets, enabling decentralized finance protocols to establish collateral parameters and manage liquidations based on reference prices tied to the underlying stock. Data sources also include corporate actions such as dividends, helping applications reference stock values accurately. According to the announcement, Sentora is establishing and monitoring risk parameters for the new lending market, including collateral ratios and liquidation thresholds.
Ondo stated that by combining exchange-linked liquidation with on chain price data, the parties aim to expand the usability of Tokenize stocks in lending and other structured products. Additional Tokenize stocks and ETFs are expected to be added as the oracle scope and protocol integration expand.
This announcement follows a partnership that began in October 2025 between Ondo Finance and Chainlink, the blockchain oracle network launched in 2017, when Chainlink was designated as the primary data provider for Ondo's Tokenize stocks and ETFs.
This event occurred amidst a surge in securities Tokenize in the U.S. Nasdaq filed a rule-changing proposal with the U.S. Securities and Exchange Commission in September to allow the listing of Tokenize versions of publicly traded stocks. On December 11, the SEC issued a no-action letter allowing a subsidiary of Depository Trust and Clearing Corporation to offer Tokenize services for deposited securities.
The New York Stock Exchange and its parent company, Intercontinental Exchange, announced on January 19th a blockchain platform for trading Tokenize stocks and ETFs with near-instantaneous settlement, while Robinhood just launched a public testnet for Robinhood Chain, Ethereum's Layer 2 network designed to support Tokenize real-world assets with 24/7 trading.
