A Swiss financial-industry group has started testing selected payment and settlement uses for CHFD, a Swiss franc-linked stablecoin, after adding financial market infrastructure operator SIX and payments provider TWINT to the initiative.
The expanded group comprises UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise, SIX, TWINT and Swiss Stablecoin AG. According to a joint announcement hosted by UBS, the tests are taking place in a controlled live environment with a restricted participant pool and transaction limits.
CHFD has been technically live in the sandbox since the end of June and is designed to maintain a one-to-one peg with the Swiss franc. The platform is operated by CHFD Infrastruktur AG, a subsidiary of Swiss Stablecoin AG. The announcement does not describe CHFD as a generally available payment product.
Programmable payments move into controlled testing
The participants plan to examine whether programmable payment logic can reduce fraud risks on online marketplaces, support fairer access to event tickets and make public-fund disbursements more efficient. The sandbox also covers automated transactions between financial institutions and tokenized settlement of digital assets.
For payments operators, the important development is the transition from an industry proposal to use-case testing. SIX adds experience in market infrastructure and securities settlement, while TWINT brings a connection to a widely used Swiss digital-payment channel. Their participation broadens the operational perspectives represented in the sandbox, but it does not by itself establish that either company will distribute CHFD or connect it to a production service.
The distinction matters because programmable payments require more than token issuance. A production design would need clear rules for authorization, transaction finality, exception handling, fraud disputes, liquidity and redemption. Marketplace and ticketing applications also raise questions about how conditional transfers interact with refunds and consumer protections. The sandbox gives the participants a limited environment in which to test those dependencies without presenting the work as a public rollout.
Settlement tests may expose integration requirements
The institutional use cases could test how a franc-linked token fits alongside existing bank money and market infrastructure. Automated bank-to-bank transactions and tokenized-asset settlement depend on coordinated operating hours, asset and cash availability, identity controls and reconciliation. SIX’s involvement may help the group assess those interfaces from an infrastructure perspective.
TWINT’s presence adds a retail-payments viewpoint, but the announcement does not specify a consumer-facing wallet integration, merchant-acceptance plan or launch timetable. It also does not disclose the underlying blockchain, reserve arrangements, issuance and redemption procedures, transaction volumes or commercial pricing. Those omissions limit what can be concluded about scalability or adoption.
The pilot remains open-ended
The test phase is expected to continue until the end of 2026. The group says it will evaluate where a Swiss franc stablecoin could add value and what technical, operational and regulatory requirements would have to be met for any future development. An overview of findings is planned after the initiative concludes.
The participants explicitly describe the sandbox as an open-outcome pilot rather than a decision to introduce a Swiss franc stablecoin. That boundary is central to interpreting the project: CHFD is active inside the controlled environment, while any broader issuance or payment deployment remains undecided.
For the Swiss payments market, the pilot creates a shared venue for banks, payment specialists and infrastructure providers to test workflows rather than debate them only at a conceptual level. The eventual significance will depend on the findings, the safeguards that prove workable and whether the participants can define a viable path beyond the sandbox.
