Swiss Banks Begin Live Tests of a Franc Stablecoin

SIX and TWINT have joined a nine-company sandbox testing CHFD for tokenized settlement, automated transactions and programmable payments.

A clear faceted token sits inside a protective ring with red light paths linking nine distinct abstract financial institutions.

Nine Swiss financial companies have begun live sandbox tests of a Swiss-franc stablecoin after SIX and payment app TWINT joined an initiative led by UBS and other banks. The tests use CHFD, a token designed to maintain a one-to-one value with the franc and technically live in the controlled environment since late June.

The group now includes UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, BCV, SIX, TWINT and Swiss Stablecoin AG. CHFD Infrastruktur AG, a subsidiary of Swiss Stablecoin, operates the platform. Adding a national market-infrastructure provider and a widely used payment app broadens the experiment beyond bank-only settlement.

The partners will test automated transactions between financial institutions, settlement of tokenized assets and programmable payments. Other use cases examine whether conditional logic could reduce marketplace fraud, improve event-ticket distribution or make public payments more efficient.

The live setting is deliberately constrained. Participation and transaction volumes are limited, allowing the group to observe technical, operational and regulatory behaviour without presenting the same exposure as an open retail launch. The test phase is due to continue through the end of 2026, after which the participants plan to publish findings.

The initiative has an open outcome. UBS explicitly says the sandbox is not a decision to issue a permanent Swiss-franc stablecoin. That distinction protects against treating an experiment as a product announcement and keeps unresolved design choices visible.

Those choices include the issuer, reserve assets, redemption rights, access rules and legal treatment of settlement. Maintaining a nominal peg in a sandbox is easier than sustaining immediate redemption under market stress. Users also need clarity on whether CHFD is a bank deposit, e-money claim or another form of private money.

SIX can help test integration with securities infrastructure, where delivery-versus-payment is a valuable use case. TWINT adds consumer-payment expertise, though the current release does not promise retail access. Combining both perspectives could reveal whether one instrument can serve wholesale settlement and programmable commerce or whether different forms of digital francs are required.

Switzerland already has a sophisticated financial market and experience with tokenized assets. A domestic franc instrument could reduce dependence on dollar stablecoins for local settlement. It could also create competition with tokenized commercial-bank deposits and any future central-bank digital money.

Why it matters

The project has moved from planning into live, multi-institution testing. The inclusion of SIX and TWINT gives it credible links to both market infrastructure and payments, making the results more relevant than a closed technical demonstration.

For banks, programmable franc money could shorten settlement chains and support new services. For securities platforms, it may provide the cash leg needed for atomic settlement. For regulators and the central bank, the sandbox offers evidence about private digital money before a broad launch creates systemic questions.

No production issuance has been approved, and the most important safeguards remain undisclosed. The value of the exercise will depend on transparent findings about finality, reserves, fraud controls, interoperability and failure recovery. Success means learning where the instrument adds value—not merely completing transactions inside a protected environment.
