According to a report on Thursday, the central banks of France, Singapore and Switzerland, along with the Bank for International Settlements (BIS), successfully experimented with cross-border transactions using wholesale central bank digital currencies (wCBDC).
The experiment, called Project Mariana, involved simulated financial institutions trading hypothetical wCBDCs of euro, Singapore dollar and Swiss franc.
The project used a public blockchain with a common token standard that enabled interoperability and seamless exchange of wCBDC across different local payment and settlement systems maintained by the central banks.
