Phase II of Project Helvetia was focused on the settlement of tokenised assets in a Wholesale CBDC (wCBDC).
Project Helvetia is a collaboration between the SNB, BIS Innovation Hub, SIX (the Swiss Exchange) and 5 large commercial banks.
SIX already offers trading and settlement of “tokenised assets”, but using privately issued forms of digital currencies / money. With Helvetia, the aim is to test the whole chain using Central Bank money instead.
