The CHFD stablecoin entered its formal testing phase on Sept. 8 after Swiss financial market operator SIX and payments provider TWINT joined seven existing participants in the controlled initiative.

The nine participants are UBS, PostFinance, Sygnum, Raiffeisen, Zurich Cantonal Bank, Banque Cantonale Vaudoise, SIX, TWINT and Swiss Stablecoin AG, according to the official announcement.

They are testing a digital asset designed to maintain a one-to-one value against the Swiss franc. One CHFD is intended to equal one CHF inside the sandbox.

The project remains experimental. Its members said the testing does not represent a decision to issue CHFD commercially or make it available to the public.

CHFD stablecoin tests move beyond basic transfers

The participating institutions will test automated transactions between financial firms and the settlement of tokenized assets. These are established institutional use cases for blockchain-based money.

A stablecoin could allow a tokenized security and its payment to move through connected digital systems. The objective would be to reduce the delay between the delivery of an asset and receipt of the corresponding funds.

SIX already operates infrastructure for issuing, trading and settling digital securities. Its digital asset platform supports tokenized securities alongside traditional assets in a regulated post-trade environment.

More than CHF2 billion in digital securities have been issued through SIX Digital Exchange, according to the company. Some transactions have settled using the Swiss National Bank’s wholesale central bank digital currency under Project Helvetia.

The CHFD participants will also study programmable payments, where predetermined conditions control when funds move. The proposed scenarios cover e-commerce, ticketing and public-sector payments.

For online marketplaces, the institutions will examine whether payment conditions can reduce fraud. A transaction could potentially release money only after agreed requirements have been satisfied.

In ticketing, the group will test whether programmable rules can support fairer access to events. The announcement did not identify participating ticket companies or explain what those controls would involve.

The public-funds scenario will assess whether conditional payments can make disbursement more efficient. No Swiss government agency was named as a participant, and the announcement does not confirm that public money is already moving through CHFD.

SIX and TWINT broaden the sandbox’s reach

SIX contributes experience in exchanges, securities settlement, custody and institutional digital assets. Its participation could help connect the payment side of CHFD with tokenized bonds, funds or other financial instruments.

Switzerland’s tokenized securities market is already processing large transactions. In related coverage, a CHF350 million digital bond was issued through SIX infrastructure, showing how regulated blockchain settlement is moving beyond small trials.

The institutions have not announced a production connection between CHFD and SIX Digital Exchange. Such an integration remains one of several possibilities being assessed.

TWINT brings expertise in consumer and merchant payments. Its mobile payment system is widely used in Switzerland for person-to-person transfers, online purchases and physical retail transactions.

TWINT’s involvement gives the initiative a participant focused on everyday payments rather than only banking and securities infrastructure. However, there is no confirmed plan to offer CHFD through the TWINT application.

The announcement also does not mean that customers of UBS, PostFinance, Sygnum, Raiffeisen, ZKB or BCV can access the token. Participation remains restricted to authorized institutions inside the controlled environment.

The sandbox began with six Swiss banks in April

UBS, PostFinance, Sygnum, Raiffeisen, ZKB and BCV originally launched the initiative with Swiss Stablecoin AG in April 2026. As crypto.news reported at the time, six major Swiss banks opened the stablecoin sandbox to examine potential applications in payments and tokenized finance.

The original initiative remained open to additional banks, companies and institutions. The arrival of SIX and TWINT expands the group from seven participating companies to nine. CHFD became technically operational inside the sandbox at the end of June. The Sept. 8 announcement marks the start of coordinated testing across the expanded group rather than the token’s first technical deployment.

CHFD Infrastruktur AG operates the platform used for the trials. The company is a subsidiary of Swiss Stablecoin AG.

The sandbox uses a limited participant group, transaction caps and other safeguards intended to contain financial and operational risks. These restrictions distinguish it from a public stablecoin circulating freely through exchanges and personal wallets. Calling the system a “live environment” means participants can test actual technical processes under controlled conditions. It does not mean CHFD has been approved for unrestricted commercial distribution.

CHFD is not a public Swiss franc stablecoin

The participants have not published a public token contract, circulation figure or exchange listing. Retail users have not been invited to buy, redeem or transfer CHFD.

No public reserve attestation accompanied the Sept. 8 announcement. The group said only that CHFD is structured to maintain a one-to-one peg with the Swiss franc.

A commercial stablecoin would need clear rules covering issuance, redemption, reserves, customer identification, transaction monitoring and the treatment of holders if the operator failed.

FINMA’s stablecoin guidance says the regulatory treatment of a Swiss stablecoin depends on its legal structure and the rights granted to holders. Anti-money laundering requirements can also apply because stablecoins may serve as payment instruments.

The current sandbox does not constitute a broad FINMA endorsement of CHFD. The participating institutions must assess the technical, regulatory and operational requirements before making any decision about wider issuance.

CHFD is also separate from the Swiss National Bank’s wholesale central bank digital currency. A wholesale CBDC represents central bank money for eligible financial institutions, while CHFD would carry claims and risks determined by its private issuance structure.

The Swiss National Bank has separately tested wholesale digital francs through Project Helvetia. Crypto.news previously reported that Switzerland extended its wholesale CBDC pilot to cover more institutions and financial transactions.

Switzerland already has competing digital francs

CHFD is entering a market where other Swiss franc-denominated digital assets already operate. These include AllUnity’s CHFAU, VNX’s VCHF and the decentralized Frankencoin.

BitGo added institutional access to CHFAU through a partnership with AllUnity. CHFAU is separate from CHFD and follows a different regulatory, issuance and distribution model.

The CHFD group’s possible advantage comes from its links to Swiss banking, mobile payments and securities infrastructure. UBS, PostFinance, Raiffeisen, ZKB and BCV provide banking reach, while SIX and TWINT add market and payment networks.

Those relationships do not guarantee adoption. The partners have not disclosed how much CHFD has been issued, how many transactions have been completed or how the platform compares with existing payment systems.

UBS has prior experience with blockchain-based money. The bank previously completed cross-border payment trials using UBS Digital Cash across Swiss francs, euros, U.S. dollars and Chinese yuan.

The earlier UBS system and CHFD are separate projects. Their common focus is the use of programmable digital money for institutional settlement and payments.

There was no identifiable cryptocurrency market reaction to the CHFD announcement. The sandbox has no publicly traded native token, while CHFD itself does not have a reported public market price.

Testing will continue through the end of 2026

The partners expect testing to continue until the end of 2026. They described the initiative as open-ended, meaning it is not designed to guarantee a commercial launch.

The trials will assess where a Swiss franc stablecoin could offer practical value and which technical, operational and regulatory obstacles remain.

The institutions plan to publish an overview after the initiative concludes. They have not provided an exact publication date or committed to releasing transaction-level data.

A broader launch would require a separate decision after the results are assessed. The participants have not announced a retail rollout, bank-account integration or exchange listing.
