Zurich, 8 September 2026 - UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, BCV, SIX, TWINT and Swiss Stablecoin AG are testing selected use cases for a CHF stablecoin in a secure digital live environment - a so-called sandbox.
The tests are based on the Swiss franc stablecoin CHFD, which has been technically live in the sandbox since the end of June. CHFD is a stablecoin designed to maintain a 1:1 peg to the Swiss franc (1 CHFD = 1 CHF). The sandbox use cases are tested on the CHF stablecoin platform operated by CHFD Infrastruktur AG, a subsidiary of Swiss Stablecoin AG.
