Swiss banks UBS, PostFinance, and Sygnum Bank have completed the first legally binding interbank payment using tokenized deposits on a public blockchain. The transaction, which occurred on September 12, 2025, demonstrated cross-bank interoperability, allowing clients to transfer deposit tokens representing real bank deposits across participating banks with on-chain settlement. This milestone underscores the growing adoption of blockchain technology in the financial industry.

The transaction involved the use of tokenized deposits, where traditional bank deposits are converted into digital tokens that can be transferred and settled on a blockchain network. This approach offers several benefits, including increased efficiency, reduced costs, and enhanced security. The use of a public blockchain ensures transparency and immutability, making the transaction process more reliable and secure.

The success of this interbank payment is a significant step forward for the financial industry. It builds on previous blockchain efforts, such as the use of smart contracts and decentralized finance (DeFi) platforms, to create more efficient and transparent financial systems. The ability to transfer deposit tokens across banks on a public blockchain opens up new possibilities for cross-border payments and interoperability between different financial institutions.

The Swiss banks' collaboration on this project highlights the potential of blockchain technology to revolutionize traditional banking practices. By leveraging the power of blockchain, banks can offer their clients more innovative and efficient financial services. The successful completion of this interbank payment also sends a strong signal to other financial institutions that blockchain technology is a viable and practical solution for modernizing financial systems.

Looking ahead, the financial industry can expect to see more innovations and collaborations in the area of tokenized deposits and cross-bank interoperability. As blockchain technology continues to evolve and gain wider acceptance, it is likely that we will see more banks and financial institutions exploring and implementing similar solutions.
