UBS, along with PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise, and Swiss Stablecoin AG, have launched a significant initiative to explore the use cases for a Swiss franc stablecoin in Switzerland. Announced on April 8, 2026, this project is designed to provide a secure digital environment for participating banks to test various stablecoin applications.
The sandbox will allow these banks to experiment with selected Swiss franc stablecoin use cases, aiming to build experience in handling digital payment methods. The infrastructure for the issuance of the stablecoin will be provided by Swiss Stablecoin AG, and the project is open to additional banks, companies, and institutions interested in participating.
This initiative represents the latest in a series of efforts by major Swiss financial institutions to investigate how blockchain technology can be integrated into existing financial systems, particularly in relation to the Swiss franc. Previously, Bitcoin Suisse AG had issued a Swiss franc-based stablecoin called CryptoFranc, or XCHF, which was intended for use as a payment token. However, Bitcoin Suisse announced on August 16, 2024, that it would cease the issuance and redemption of this stablecoin.
According to data from Advratings, UBS Group is currently the largest Swiss bank, boasting total assets of $1.7 trillion. Other significant players include Raiffeisen Schweiz with $353 billion in assets, Zürcher Kantonalbank with $241 billion, and PostFinance with $121 billion.
Exploring Blockchain Payment Methods
In September 2025, UBS, PostFinance, and Sygnum Bank successfully completed a proof of concept for deposit tokens under the auspices of the Swiss Bankers Association. This trial focused on testing legally binding interbank payments via a public blockchain, which is pivotal for future digital transactions.
The Swiss Bankers Association reported that the trial explored the feasibility of using tokenized deposits to facilitate secure and programmable transactions on public blockchains, while also ensuring compliance with Swiss financial regulations. Key use cases included facilitating payments between bank customers and testing escrow-like exchanges involving tokenized real-world assets.
While the trial confirmed the viability of institutional blockchain payments, the Swiss Bankers Association emphasized that scaling these payment solutions will require further design adjustments and enhanced collaboration with other banks, regulatory authorities, and infrastructure providers.
This collaborative approach reflects a broader trend among Swiss banks to leverage blockchain technology to modernize and enhance payment systems. As these institutions continue to explore innovative digital solutions, the potential for a Swiss franc stablecoin could significantly influence the future landscape of financial transactions in Switzerland.
In summary, the sandbox initiative led by UBS and its partner banks is a pivotal step toward integrating blockchain technology into the Swiss financial ecosystem. By fostering collaboration and experimentation, these institutions are positioning themselves at the forefront of financial innovation, aiming to enhance the efficiency and security of digital payment methods.
