Matter Labs Builds ZKsync Fee Switch Into Prividium Connect Launch

Matter Labs has launched Prividium Connect, an atomic settlement product for institutional exchanges, and disclosed that a fee mechanism routing interoperability revenue toward ZKsync's Fee Flow system is built and under audit.

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

If an exchange misses its deadline, each party can recover committed assets without the other party's cooperation. Neither side can unilaterally reverse a completed exchange. Atomic does not mean instant, however. The product page states that completion still depends on proof verification and the finality of the chosen settlement layer. Institutions are directed to an evaluation process, with supported configurations confirmed for each implementation.

How does Connect fit the Prividium stack?

Connect integrates with Prividium Commander, the digital-asset operations control product Matter Labs introduced in October, though the two products can run independently. At the October launch, CEO Alex Gluchowski told The Defiant that Commander's revenue went to Matter Labs, not to ZKsync tokenholders. That distinction frames the significance of the new proposal.

The fee 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 in the off position and, when enabled, charges chain operators per interoperability call. The forwarder that would route collected fees to Fee Flow remains separate future work.

What does the fee switch change for ZKsync?

The existing Fee Flow design lets anyone claim accumulated approved fee assets by paying a governance-set amount of ZK. That ZK then flows 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 interoperability fees to those contracts remains subject to approval.

For practitioners, the structure matters in two ways. First, institutions deploying Connect can operate the product themselves or choose a provider, which keeps the operational perimeter flexible. Second, the fee route applies specifically to canonical public deployments, not to a commitment to direct all Prividium software revenue into ZK. The boundary between Matter Labs' commercial revenue and value accrual to the ZKsync ecosystem stays deliberate and narrow.

What does this change for institutions evaluating settlement infrastructure? It offers a middle path: the confidentiality guarantees of zero-knowledge proofs combined with the counterparty protection of atomic delivery-versus-payment, without requiring a bespoke legal arrangement to enforce recovery if a counterparty stalls.

The immediate milestone to watch is the audit of the fee switch and the subsequent governance decision on wiring interoperability fees into the already-deployed Fee Flow contracts on ZKsync Era.
