UBS Launches CHFD Swiss Franc Stablecoin Testing With SIX And TWINT Partners

Nine Swiss institutions began a CHFD pilot, testing interbank settlements and tokenized assets. CHFD entered live testing as SIX and TWINT joined as new partners.

CHFD goes live
A Swiss franc stablecoin called CHFD entered a formal testing phase on September 8, with UBS confirming that financial market operator SIX and payments giant TWINT joined as new partners. The CHFD initiative is built around a Swiss franc-denominated token designed to maintain a 1:1 peg to the Swiss franc, and UBS said the sandbox is not part of a formal CHFD launch process. Reuters reported that the tests are based on CHFD, which has been technically live in the sandbox since late June, and that the scheme aims to generate insights for the further development of the Swiss digital money ecosystem.
The expanded effort turns what started as a six-bank experiment into a nine-institution effort spanning banking, securities infrastructure and everyday mobile payments, with the roster including UBS, PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank, Banque Cantonale Vaudoise, Swiss Stablecoin AG, SIX and TWINT. Bloomingbit said the pilot is scheduled to run through the end of this year, while also stating that the sandbox is a stage to review the technical, operational and regulatory requirements needed to assess possible future adoption.

What they will test
Across the CHFD sandbox, participants plan to test automated transactions between financial institutions, the settlement of tokenized assets, and programmable payments that follow conditional “if this, then that” logic. The Cryptonomist described programmable payments extending into e-commerce, ticketing and public-sector disbursements, including testing whether conditional payments can cut down on fraud by releasing funds only once agreed requirements are met. Cointelegraph similarly said the pilot will examine whether programmable payments can reduce fraud on online marketplaces, support fair access to event tickets and make public payments more efficient, according to a Tuesday press release shared with the outlet.
Reuters’ framing tied the initiative to broader competitiveness goals, saying the bank’s statement described the scheme as aiming to strengthen the competitiveness of Switzerland's financial centre. Bloomingbit added that the participants said they plan to test a range of use cases, including automated transactions between financial institutions, settlement of tokenized assets and programmable payments, while also noting that the sandbox is not part of a decision process for an actual CHFD launch.

Broader implications
While the CHFD sandbox remains permissioned and experimental, the Reuters report placed the effort in the context of banks grappling with the growing stablecoin industry and wider growth of cryptocurrencies. The Cryptonomist said the group has not published a reserve attestation, a public token contract or any circulation figures, and that the token exists strictly inside a permissioned environment run by CHFD Infrastruktur AG, a subsidiary of Swiss Stablecoin AG. In a separate warning tied to stablecoin adoption, South Korea’s budget office warned that stablecoin adoption could reduce banks' roles as credit intermediaries and potentially destabilize token pegs during mass redemptions.
The Cryptonomist also noted that SIX already supports tokenized securities and that some transactions have settled using the Swiss National Bank’s wholesale central bank digital currency under Project Helvetia, while adding that no production integration between CHFD and SIX Digital Exchange has been announced. Bloomingbit said UBS stated the sandbox is not part of a decision process for an actual CHFD launch, but rather a stage to review the technical, operational and regulatory requirements needed to assess possible future adoption.
