According to an official UBS announcement, nine Swiss institutions—UBS, PostFinance, Sygnum, Raiffeisen, Zurich Cantonal Bank, BCV, SIX, TWINT, and Swiss Stablecoin AG—officially launched the sandbox testing phase for a CHF stablecoin on September 8, 2026. Conducted in a controlled, real-time sandbox environment, the test utilizes the digital stablecoin CHFD, which is pegged at a 1:1 ratio to the Swiss Franc. Key focus areas include innovative application scenarios such as automated inter-institutional transactions, tokenized settlement of digital assets, and programmable payments. Specific test cases involve mitigating online marketplace fraud risks, ensuring equitable distribution of event tickets, and enhancing the efficiency of public fund disbursements. The testing period is scheduled to run through the end of 2026, with results intended to inform the future development of Switzerland’s digital currency ecosystem.

According to The Block, SIX Group, a leading European stock exchange operator, announced that its Swiss exchange, SIX Swiss Exchange, and Spain’s BME Exchange will bring stock market data on-chain via Chainlink nodes. This collaboration enables smart contracts to directly read market data from both exchanges, facilitating the development of blockchain use cases such as tokenized stock indices, structured products, decentralized finance (DeFi) applications, and prediction markets. The combined market capitalization of the two SIX Group exchanges totals €2 trillion, making this initiative a trusted data source for the global financial ecosystem. Previously, prominent financial institutions—including Deutsche Börse, FTSE Russell, and S&P Global—as well as cryptocurrency companies such as Coinbase, have also launched similar partnerships with Chainlink. Since its launch last year, Chainlink’s DataLink service has been integrated into thousands of decentralized applications and across dozens of blockchains.
