Switzerland’s CHFD stablecoin initiative has entered its formal testing phase, with financial-market operator SIX and payments provider TWINT joining the consortium. Nine Swiss financial and infrastructure companies are now testing a Swiss franc-pegged stablecoin in a controlled live environment, extending an initiative first launched in April 2026.
According to an official announcement from TWINT, CHFD has been technically live inside the sandbox since late June and is designed to maintain a 1:1 peg with the Swiss franc. The test phase began on September 8 and is expected to continue through the end of 2026, with no commitment yet to launch CHFD commercially.
SIX and TWINT Expand the Sandbox
The consortium now includes UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise, SIX, TWINT and Swiss Stablecoin AG. SIX adds financial-market infrastructure expertise while TWINT brings experience in digital consumer payments, broadening the project beyond purely bank-to-bank experimentation.
Testing is taking place on a CHF stablecoin platform operated by CHFD Infrastruktur AG, a subsidiary of Swiss Stablecoin AG. The sandbox uses a restricted participant base and transaction limits to test CHFD under realistic conditions while containing operational exposure.
Potential use cases include automated transactions between financial institutions and tokenized settlement of digital assets. Participants will also examine programmable payments, including mechanisms intended to reduce fraud in online marketplaces, support fairer ticket distribution and make public-sector payments more efficient. The tests are designed to determine where programmability can create practical advantages over conventional payment workflows.
The project remains exploratory. Organizers said the objective is to identify technical, operational and regulatory requirements, as well as potential obstacles, before deciding whether further development is justified. The sandbox is explicitly a pilot and does not represent a decision to introduce a production CHF stablecoin.
CHFD Tests Institutional and Retail Payments
The addition of SIX creates a potential bridge between tokenized money experiments and established securities-market infrastructure, while TWINT introduces a consumer-payment perspective. That combination allows the consortium to test CHFD across both institutional settlement and retail-oriented payment scenarios rather than limiting the project to a single financial use case.
For financial institutions, the central questions include whether tokenized francs can improve settlement speed, automation and liquidity management without compromising existing operational safeguards. CHFD’s value proposition rests on combining the stability of bank-denominated Swiss francs with blockchain-based programmability and continuous digital settlement.
The partners expect to publish an overview of their findings after the testing phase concludes. The outcome will help determine whether a CHF stablecoin can deliver enough operational and economic value to justify moving beyond the sandbox, while identifying the infrastructure and regulatory conditions required for any future rollout.
