Swiss Franc Stablecoin Sandbox Begins Testing With SIX and TWINT

A Swiss initiative exploring a stablecoin linked to the Swiss franc has entered its testing phase, according to Cointelegraph. Financial market operator SIX and payment app TWINT have joined the sandbox, expanding a group that already includes numerous banks. The initiative is focused on developing a Swiss franc-based stablecoin, although the supplied information does not specify its launch date, design, or intended use cases. The addition of SIX and TWINT brings participation from both financial-market infrastructure and digital payments as the project moves from planning into testing. The development may be relevant to crypto-market observers tracking stablecoin projects and Switzerland’s digital-asset ecosystem. Cointelegraph reported the update on September 8, 2026.
