UBS and Nethermind have proven that Ethereum is ready for banking standards.
Swiss banking giant UBS, together with the Nethermind development team, has successfully completed two pilot projects that clearly demonstrate: the public Ethereum network is capable of meeting the strict operational and regulatory requirements of regulated financial institutions. This is not just another experiment—it is a crucial step towards making Ethereum's infrastructure accessible to the world's largest banks.
The key takeaway from the pilots is that banks can implement rigorous compliance checks through their own systems operating on top of Ethereum, without making any changes to the blockchain itself. This approach keeps the network open and neutral, while the solution itself remains fully compatible with the broader Ethereum ecosystem.
How it works in practice
UBS and Nethermind addressed compliance requirements at two key stages of sending transactions to the Ethereum network. First, they configured an Ethereum node to apply customizable compliance and risk management rules. These rules include restricting transactions to only pre-approved addresses and blocking certain interactions with smart contracts. This gives the bank full control over which operations enter the network.
In the second stage, the companies developed a component that directs batches of approved transactions through relay services directly to selected block builders, ensuring reliable inclusion in the blockchain. The entire end-to-end process was successfully tested on the Sepolia testnet. This confirmed that compliant transactions are consistently processed and recorded, with neither pilot involving real transactions.
Participants' perspectives
According to Andreas Kubli, head of digital assets at UBS, the bank is purposefully building the foundational infrastructure to support tokenized and digital assets, focusing on client interests and a responsible approach. He emphasized that the pilots demonstrated the value of close collaboration between UBS and Nethermind in shaping a new generation of blockchain infrastructure. The results show that institutional-level control and compatibility with the public network are achievable without compromising Ethereum's openness and neutrality.
Tomasz Kurowski, head of corporate at Nethermind, added that implementing control mechanisms at the infrastructure level proved that institutional requirements can be met without sacrificing the network's openness and compatibility. UBS and Nethermind plan to continue this work as technology and the regulatory environment evolve.
My analysis: This case is a powerful signal for the entire traditional financial sector. It breaks the myth that public blockchains are inherently incompatible with banking compliance. We see a pragmatic approach: not breaking Ethereum, but building the necessary control layers on top of it. If giants like UBS are actively investing in this compatibility, mass institutional adoption is no longer a question of "if" but a question of "when."
