UBS and Nethermind complete Ethereum compliance PoCs on Sepolia, testing bank-grade controls without protocol changes. UBS and Nethermind have completed two proofs of concept focused on Ethereum compliance tools. The work tested how regulated firms could use public blockchain infrastructure. The companies said the tests showed that Ethereum can support bank-grade compliance needs. They also said the protocol itself did not need to be changed. Both tests were completed on Sepolia, Ethereum’s public test network. The companies confirmed that no live transactions were used. The project comes as banks and asset managers continue testing public blockchain networks. Many firms still need stronger controls before using open networks at scale. UBS and Nethermind Test Ethereum Controls UBS and Nethermind tested tools that allow firms to apply rules before sending transactions. This gives institutions more control over activity linked to their own systems. The first proof of concept used a customized Ethereum node. The node applied compliance and risk rules to outgoing transactions before they reached the network. Those rules could limit transactions to approved wallet addresses. They could also block certain smart contract activity based on internal policy needs. As a result, banks could add controls through their own infrastructure. Ethereum’s base layer would remain open, public, and unchanged. Approved Transactions Routed to Builders The second proof of concept focused on how approved transactions move toward block production. UBS and Nethermind built a routing tool for approved transaction bundles. The tool sent approved bundles through relay services to selected block builders. This gave the firms another way to manage how transactions reach Ethereum. 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.

Approved transactions were processed and recorded during the test. However, the trial did not involve live funds or mainnet activity. It was designed to test the process in a safe environment.

He said this can happen without weakening Ethereum’s openness or neutrality.

These firms often need rules for access, screening, and transaction control. The work shows that compliance tools can sit above Ethereum. Therefore, regulated firms may not need private networks for every blockchain use case. For Ethereum, the tests add another example of institutional interest in public networks. They also show how banks can test blockchain access without changing the core protocol.
