UBS and Nethermind have completed two joint proofs of concept showing that a public, permissionless network can support the compliance and operational needs of regulated financial institutions. The PoCs show that banks and asset managers can apply strong compliance controls through the infrastructure they run on top of Ethereum, without changing how the protocol itself works. We built and tested a node that applies customizable compliance rules to outgoing transactions, and a routing component that sends approved bundles directly to selected block builders. Both validated end-to-end on Sepolia, no live transactions. This is what enterprise-grade blockchain infrastructure built on deep protocol expertise looks like in practice. We plan to build on this work with @UBS. Full release: https://www.ubs.com/global/en/media/display-page-ndp/en-20260623-nethermind.html(Nethermind)
