Matter Labs Launches Prividium Connect With ZK Fee Plan

Matter Labs, the developer behind ZKsync, launched Prividium Connect on Nov. 10, saying the software lets institutions exchange assets privately across separate blockchains without a trusted intermediary.

The company also proposed routing interoperability fees from canonical public deployments into ZK through the existing Fee Flow system. Activation, integration and fee parameters still require governance approval, separating the product launch from the proposed token economics.

Matter Labs says Connect has reached mainnet, starting with Hyperledger Besu and Prividium Ledger. Each institution runs a connector alongside its existing blockchain. Participants choose Ethereum or another Ethereum-compatible settlement chain, including a private chain, on which the outcome becomes final.

Connect makes exchanges atomic: both transfers complete or neither does. Zero-knowledge proofs establish that the agreed terms were met without exposing the underlying records. For a securities trade, delivery and payment are conditional on each other, preventing one party from delivering without being paid, according to Matter Labs.

If an exchange misses its deadline, each party can recover committed assets without the other's cooperation, the company says. Neither party can unilaterally reverse a completed exchange. Atomic does not mean instant: the product page says completion still depends on proof verification and the chosen settlement layer's finality.

That page directs institutions to an evaluation, with supported configurations confirmed for each implementation.

A Proposed Route From Fees to ZK

Connect integrates with Prividium Commander, but the products can run independently. Commander, introduced in October, controls institutions' digital-asset operations. At that launch, CEO Alex Gluchowski told The Defiant that Commander's revenue went to Matter Labs, not ZKsync tokenholders. The new plan concerns interoperability fees from canonical public deployments of Connect.

“The fee switch is built and being audited,” ZKsync said in its announcement thread. The linked GitHub change describes a switch that starts off and, when enabled, charges chain operators per interoperability call. It leaves the forwarder that would route fees to Fee Flow for separate work.

The existing Fee Flow design lets anyone claim accumulated approved fee assets by paying a governance-set amount of ZK. That ZK then goes to a splitter for burning or distribution under governance-set parameters. Matter Labs says the Fee Flow contracts are already deployed on ZKsync Era; connecting the proposed fees to them remains subject to approval.

Institutions can also operate Connect themselves or choose a provider. The proposed fee route is specifically tied to canonical public deployments, rather than a commitment to direct all Prividium software revenue into ZK.
