Six major Swiss banks launch Swiss franc stablecoin sandbox testing project

Mars Finance news: six major Swiss banks, including UBS and PostFinance, have partnered with the Swiss stablecoin company to launch a sandbox testing program for Swiss franc stablecoins. The goal is to simulate real payment workflows, explore how blockchain connects with traditional financial systems, and investigate the use cases for programmable money. Currently, Switzerland has no widely used, regulated Swiss franc stablecoin; this initiative aims to gather operational experience in a controlled environment as a foundation for a potential official stablecoin launch. The sandbox tests will take place within 2026, using a “digital real-time environment” model, with limits on the number of users and transaction volumes to control risk, focusing on testing payment settlement speed and programmable money use cases. The project is open to other banks, enterprises, and institutions. Participants hope to learn the practicality of stablecoins in real financial services through actual simulations and to assess whether to move forward with fully commercial stablecoin issuance. This project is similar to efforts by other European banks to promote euro stablecoins, with the aim of reducing reliance on dollar stablecoins and strengthening the competitiveness of the Swiss franc in the digital payments space.
