UBS Tests Key4 Gold Product on Ethereum Layer-2 Network ZKSync

Swiss banking giant UBS has made significant strides in blockchain technology by recently testing its Key4 Gold product on the Ethereum Layer-2 network, ZKSync.

Swiss banking giant UBS has recently tested its Key4 Gold product on the Ethereum Layer-2 network, ZKSync, in a bid to evaluate how blockchain could be used to enhance gold investment.

The Proof-of-Concept (PoC) was carried out within a ZKSync test network, forming part of UBS’s Space Research and Development (SR&D) activities as part of its wider blockchain initiatives, which have included previous projects like uMint and tokenised money market investments.

The bank is exploring blockchain solutions to create fractional gold investment services aimed at retail clients.

UBS’s Key4 Gold product offers clients a range of benefits, including access to real-time gold market values and unlimited transaction volumes, while also ensuring secure storage options and the possibility of physical delivery of their gold. The UBS Gold Network operates on a permissioned blockchain that connects vaults with liquidity providers and distributors.

To carry out the blockchain trial, three key challenges had to be overcome by UBS. Scalability was a major concern, as the system needed to be able to efficiently process high transaction volumes, while also ensuring strong customer data protection.

According to blockchain experts, the initiative by UBS is a significant development. The Validium mode from ZKSync helped to resolve operational issues by enabling off-chain data placement, which increases transaction speed and efficiency.

During the testing phase, UBS activated smart contracts to represent real-world gold transactions, allowing for the creation of gold tokens and the recording of any discrepancies.

Commenting on the trial, Christoph Puhr, the Digital Assets Lead at UBS, highlighted the barriers that digital finance faces in scaling operations, maintaining user privacy, and enabling cross-system communication. The demonstration using ZKSync applications showcased how second-layer networks can help to address these challenges.

The trial by UBS forms part of a wider push to make tokenised gold investments commercially viable. As interest in Web3 solutions continues to grow, blockchain technology is set to continue reshaping banking, ultimately showing how financial institutions are turning to decentralised technology to define the future of finance.
