Matter Labs Launches Private Cross-Chain Swap Tool for Institutions

Matter Labs launched Prividium Connect on mainnet, giving banks, asset managers and financial market infrastructure providers a way to swap assets privately across their own blockchains without a trusted intermediary.

The system uses zero-knowledge proofs to check agreed terms before settlement and ensure both sides complete a transfer together or neither does. Each institution keeps its confidential records in its own systems.

The setup is aimed at institutions seeking to settle transactions across separate ledgers while keeping sensitive operational data within systems they control.

Matter Labs is also proposing a standard deployment on public chains that would route interoperability fees into the ZK economy. The fee switch has been developed and is undergoing an audit.

Under the proposal, fees would be converted into ZK through the Fee Flow System already deployed on ZKsync Era, with governance deciding how tokens are distributed.
