SIX Taps Chainlink to Deliver Equities Data Onchain

• SIX brings Swiss and Spanish equities data onchain via Chainlink, expanding access across 75 blockchain networks.

• Integration enables tokenized assets, DeFi products, and prediction markets using verified institutional data.

• DataLink supports secure, compliant delivery, meeting rising demand for reliable data in blockchain finance.

SIX, Switzerland’s financial market infrastructure operator, has brought equities data onchain through Chainlink’s DataLink service. The rollout makes Swiss and Spanish exchange data accessible across blockchain networks. The integration, announced this week, allows institutions and developers to use regulated market data within smart contracts at scale.

Institutional Data Reaches Blockchain Networks

According to Sergey Nazarov, institutional demand is pushing traditional financial data onchain. He said firms now require reliable data layers before committing capital to tokenized assets.

Through this integration, SIX distributes equities data tied to over €2 trillion in market value. The data spans listings from exchanges in Switzerland and Spain.

Notably, the information becomes available to more than 2,600 applications across over 75 blockchain networks. Developers can now access this data programmatically within standardized smart contract systems.

DataLink Expands Use Cases for Digital Assets

The rollout relies on Chainlink’s DataLink, an institutional-grade data delivery service. This system enables secure transmission of market data across both public and private blockchains.

As a result, new financial products can emerge using verified equity data. These include tokenized indices, structured products, and compliant decentralized finance applications.

Additionally, prediction markets and other smart contract-based tools can integrate regulated data sources. This expands how blockchain systems interact with traditional financial markets.

Executives Highlight Infrastructure and Access

Matthew Nurse, Head of Market Data at SIX, said the integration delivers real-time data through secure infrastructure. He noted that Swiss and Spanish equities now operate within blockchain environments.

Meanwhile, Fernando Vázquez said DataLink enables providers to distribute premium data while maintaining control standards. He added that the system supports compliance requirements for regulated institutions.The collaboration also shows Chainlink’s broader role in data delivery. According to Nazarov, it already supports a large share of decentralized finance applications globally.
