UBS, in collaboration with PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise, and Swiss Stablecoin AG, has announced the launch of a sandbox to explore the use cases for a Swiss franc stablecoin in Switzerland. This initiative, revealed on Wednesday, is set to take place in 2026 and aims to provide a secure digital environment for participating banks to test various applications of the stablecoin.
The sandbox will enable the banks to gain firsthand experience in managing digital payment methods, with Swiss Stablecoin AG facilitating the necessary issuance infrastructure. Importantly, the project will also be open to other banks, companies, and institutions that express interest in participating.
This initiative is the latest in a series of efforts by major Swiss financial institutions to investigate how blockchain technology can enhance the functionality of the Swiss franc. Previous to this, Bitcoin Suisse AG had launched the CryptoFranc (XCHF), a Swiss franc-based payment token. However, in August 2024, Bitcoin Suisse announced it would discontinue the stablecoin, ceasing both issuance and redemption operations.
According to data from Advratings, UBS Group holds the title of the largest Swiss bank, boasting total assets of $1.7 trillion, followed by Raiffeisen Schweiz at $353 billion, Zürcher Kantonalbank at $241 billion, and PostFinance at $121 billion.
Exploring Blockchain Payment Innovations
The initiative comes on the heels of a successful deposit token proof of concept completed in September 2025, where UBS, PostFinance, and Sygnum Bank collaborated under the auspices of the Swiss Bankers Association. This trial aimed to assess the viability of legally binding interbank payments facilitated by a public blockchain.
During this trial, the Swiss Bankers Association confirmed the potential of tokenized deposits to support secure and programmable transactions on public blockchains while ensuring compliance with Swiss financial regulations. The trial explored various use cases, including payments between bank customers and an escrow-like exchange involving tokenized real-world assets.
Although the trial established the feasibility of institutional blockchain payments, the Swiss Bankers Association noted that scaling these payment solutions necessitates additional design adjustments and greater collaboration with other banks, regulatory authorities, and infrastructure providers.
This sandbox initiative signifies a strategic move by UBS and its partners to remain at the forefront of the evolving landscape of digital finance, particularly as central banks globally explore the implications of digital currencies. The collaboration is expected to yield valuable insights into the operational challenges and opportunities associated with integrating stablecoins into traditional banking frameworks.
As the banking sector increasingly embraces digital transformation, this project highlights the importance of developing secure and efficient payment systems that can leverage the advantages of blockchain technology. By providing a structured environment to test these innovations, UBS and its partners are paving the way for future advancements in digital currencies and payment systems.
