A Swiss franc stablecoin sandbox starts testing and adds SIX and TWINT
UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, BCV, SIX, TWINT and Swiss Stablecoin AG began testing use cases for CHFD, a franc token technically live since the end of June 2026. Circulation is held below CHF 1m so the Swiss fintech sandbox exemption applies. The test phase runs to the end of 2026 and is not a decision to launch.
