The core event, announced on April 8, 2026, involves UBS partnering with PostFinance, Sygnum, Raiffeisen, Zürcher Kantonalbank (ZKB), Banque Cantonale Vaudoise (BCV), and Swiss Stablecoin AG, which provides issuance infrastructure.[1][2][4][6][8] These institutions, managing over $6 trillion in assets collectively—with UBS at $1.7 trillion—will simulate real blockchain-based payments, settlements, programmable money via smart contracts, and integration with traditional banking systems under risk controls like transaction limits.[1][3][4][5][6] The sandbox is open to additional banks, companies, and institutions.[1][2][6][8][11]
This follows prior Swiss blockchain trials, including UBS, PostFinance, and Sygnum's 2025 tests of tokenized deposits and cross-bank payments on public blockchains under the Swiss Bankers Association, plus a discontinued XCHF stablecoin by Bitcoin Suisse in 2024.[1][8][9] No widely regulated CHF stablecoin currently exists for broad use in Switzerland.[4][6][8][10]
The initiative is newsworthy as a cautious step by traditional finance giants toward blockchain payments amid a $320 billion stablecoin market and projected $56.6 trillion in flows by 2030, positioning Switzerland as a regulated digital currency hub similar to Europe's Qivalis digital euro project. [4][6][10] It emphasizes efficiency gains like faster settlements and lower costs while prioritizing compliance in a system with robust existing rails.[3][6][8]
