- Chainlink has added market data from SIX Swiss Exchange and Spain’s BME Exchange to its DataLink service.
- The integration will make Swiss and Spanish equities data readable by smart contracts for tokenized and blockchain-based financial products.
Chainlink has added another traditional market data provider to its onchain network, this time bringing the SIX family of Swiss and Spanish exchanges into its DataLink service.
The move means data from SIX Swiss Exchange and BME Exchange in Spain will now be made directly accessible to smart contracts. In practical terms, that gives developers a new set of building blocks for products such as tokenized stock indices, structured products, DeFi applications, prediction markets, and other blockchain-based financial tools.
Swiss and Spanish exchange data moves into smart contracts
This is the latest sign that proprietary exchange data is becoming a more serious part of the tokenization stack. For years, one of the main bottlenecks in bringing real-world financial assets onchain has been the quality and reliability of offchain data. Smart contracts can only do so much if the market information feeding them is incomplete, delayed or hard to trust.
That is why this kind of integration matters more than it may first appear. Chainlink is not simply adding another ticker feed. It is extending access to institutional-grade equities data from two established European exchange groups.
SIX’s head of market data, Matthew Nurse, said the integration would bring flagship Swiss and Spanish blue-chip equities onchain through Chainlink’s infrastructure, enabling digital asset applications to draw on real-time market information through a more secure and established system.
Tokenization keeps pulling in larger financial names
The two SIX Group exchanges represent around €2 trillion in combined market capitalization, which gives the partnership real weight. It also fits a wider pattern. Chainlink has already signed similar deals with FTSE Russell, Deutsche Börse and S&P Global, while BX Digital and BX Swiss, part of the Boerse Stuttgart Group, partnered with Chainlink just last week.
That growing list says something fairly clear. As tokenization moves from theory into market infrastructure, large financial data brands increasingly want a role in how real-world assets are represented and priced onchain.
