Swiss franc stablecoin testing environment launched by UBS and banking consortium
A collaborative initiative between UBS, PostFinance, Sygnum and additional partners has introduced a sandbox environment set for 2026 to explore Swiss franc stablecoin applications and blockchain-based payment infrastructure within Switzerland.
A consortium comprising UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise and Swiss Stablecoin AG has initiated a testing environment designed to explore potential applications for a stablecoin pegged to the Swiss franc within Switzerland's financial ecosystem.
The announcement came on Wednesday, revealing that the collaborative effort will enable the participating financial institutions to evaluate specific use cases for the franc stablecoin within what the partners characterized as a protected digital operational environment or sandbox. According to the consortium, this initiative aims to develop expertise in managing digital payment solutions.
The testing environment is scheduled to operate throughout 2026, with Swiss Stablecoin AG supplying the underlying issuance infrastructure. Additionally, the initiative remains accessible to other financial institutions, corporate entities and organizations interested in participating in the project.
This initiative represents the most recent endeavor by prominent Swiss banking institutions to evaluate how financial applications built on blockchain technology can integrate with the Swiss franc.
Bitcoin Suisse AG had previously launched the CryptoFranc, or XCHF, a Swiss franc-backed digital asset that the company characterized as a payment token. However, Bitcoin Suisse made an announcement on Aug. 16, 2024, stating its decision to terminate the stablecoin, ceasing both its issuance and redemption processes.
According to information from Advratings, UBS Group holds the position as Switzerland's largest banking institution with $1.7 trillion in total assets, with Raiffeisen Schweiz following at $353 billion, Zürcher Kantonalbank at $241 billion and PostFinance at $121 billion in total assets.
Swiss banks explore blockchain-based payment methods
During September 2025, UBS, PostFinance and Sygnum Bank successfully concluded a proof of concept for deposit tokens under the auspices of the Swiss Bankers Association, which examined legally enforceable interbank payment transactions conducted on a public blockchain network.
According to the Swiss Bankers Association, the pilot program evaluated whether tokenized deposits had the capability to facilitate secure, programmable transaction processing on public blockchain networks while maintaining adherence to Swiss financial regulations. Among the tested scenarios, one use case examined payment flows between customers of different banks, while an additional use case explored an escrow-type exchange mechanism involving tokenized real-world assets.
Although the trial validated the "feasibility" of institutional-grade blockchain payment systems, the SBA emphasized that expanding the scale of these payment solutions necessitates "additional design adjustments" and more extensive collaboration with other banking institutions, regulatory authorities and infrastructure service providers.
