This highlights a pioneering Blockchain-Based Interbank payment between UBS, Sygnum Bank, and PostFinance using Ethereum, marking the first legally binding interbank transaction on a public blockchain, a significant leap from traditional systems as validated by a Swiss Bankers Association study on September 16, 2025.
This proof-of-concept leverages deposit tokens—digital representations of bank deposits—demonstrating potential efficiency gains, with a 2023 BIS study showing blockchain could reduce cross-border payment costs by up to 30% compared to legacy networks.
The collaboration challenges the slow adoption narrative in traditional finance, with Switzerland’s advanced regulatory framework enabling this test, contrasting with the U.S., where central bank experiments like Project Pine remain in early stages.
