SIX and Chainlink Put Data on €2 Trillion of European Stocks Onchain

SIX operates Switzerland’s SIX Swiss Exchange and Spain’s BME Exchange, making it a major provider of regulated market infrastructure in Europe. Delivering real-time exchange prices to smart contracts through Chainlink DataLink allows official traditional-finance data to directly support DeFi and tokenized assets, while reducing the risk of onchain products relying on unofficial price quotes.

On April 15, 2026, SIX and Chainlink announced that data covering more than €2 trillion in stocks listed on the two exchanges had been brought onchain through DataLink, including major Swiss and Spanish blue-chip shares. The data is accessible to more than 2,600 applications in the Chainlink ecosystem across more than 75 public and private blockchains.
