UBS-led group of Swiss banks launches secure sandbox to pilot CHF stablecoin payments and settlements

UBS and five other Swiss banks said they will test use cases for a Swiss franc stablecoin by launching a secure digital live environment (sandbox) to explore ways to connect blockchain-based applications with the Swiss franc. Participants named in the initiative include UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank (ZKB) and Banque Cantonale Vaudoise (BCV) ^{[1] [2]}.

The project responds to rising interest in blockchain-based payments and aims to assess whether a Swiss franc stablecoin could improve settlement speed and operational efficiency. The sandbox structure will allow institutions to trial integrations and potential business cases in a controlled live setting before any broader deployment ^{[2] [3] [1] [4]}.

The collaboration is a coordinated testing effort by traditional banks to explore digital-currency infrastructure rather than an immediate launch; further steps will follow based on sandbox results and participating banks' decisions ^{[2] [1]}.
