SIX and Chainlink announced today that equities data from the exchanges of SIX is available onchain for the first time via DataLink, an institutional-grade data publishing service powered by the Chainlink data standard, which underpins secure data delivery across leading public and private blockchain ecosystems.

Through Chainlink, SIX is extending its reach into blockchain market infrastructure by making data for equities listed on its exchanges in Switzerland and Spain, equivalent to over €2 trillion in market capitalization, available to over 2,600 applications across more than 75 blockchains. Equities data from the SIX Exchanges can now be programmatically accessed within standardized smart contract environments at scale.

By bringing data onto a vast blockchain network, SIX and Chainlink are accelerating the availability of equities data onchain and new digital asset market infrastructure. This unlocks new use cases, including tokenized indices, structured products, compliant DeFi applications, prediction markets, and new trading primitives, based on high-quality equity market data.
