UBS Teams Up With Nine Institutions to Launch CHF Stablecoin Sandbox Testing, With SIX and TWINT Joining

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.
