Banks have spent years running blockchain experiments. Very few of those experiments ever turned into a product a customer could actually use.
Matter Labs CEO Alex Gluchowski thinks he knows why, and his answer is less exciting than you might expect. In his view, the culprit is not the technology but the plumbing.
On October 21, 2026, Gluchowski used Money20/20 USA to launch Prividium Commander, a tool Matter Labs is positioning as the missing link between a successful bank pilot and a live, scaled deployment.
The pilot-to-production gap
The core argument is simple. Most banks have tested blockchain, Gluchowski said, but only a small number have moved those tests into production services.
He pinned the blame on operational issues rather than technical limits. Think issuance controls, how transfers are handled, audit requirements and compliance workflows.
Prividium Commander is pitched as a unified control plane for that job. Institutions can use it to manage permissions, configure what their tokens can do and set operational policies from one place.
It is also designed to connect with the legacy financial systems banks already run. And it can work across both public and private blockchain infrastructure.
The practical promise: banks would no longer need custom engineering for every new use case. Each new tokenized product would not have to start from a blank sheet.
What Prividium actually is
Commander sits on top of Prividium, Matter Labs’ permissioned, privacy-focused blockchain platform. It is built on the company’s ZK Stack technology.
Prividium lets an organization run a private chain on its own infrastructure. Those transactions are then anchored to Ethereum using zero-knowledge proofs.
A zero-knowledge proof lets one party prove a statement is true without revealing the underlying data. For a bank, that means getting Ethereum-grade settlement finality without broadcasting client balances or transaction details to the world.
The launch caps a busy stretch for the platform. In September 2026, Matter Labs open-sourced Prividium Core, the permissioning engine that governs who can do what on a given chain.
The Deutsche Bundesbank was the first tester of that engine.
Prividium has also picked up a notable US customer. Cari Network selected the platform for a multi-bank tokenized deposit platform involving regional banks including Huntington and M&T Bank.
A production launch for that platform is planned for later in 2026.
A company that bet on the bank
Matter Labs is best known in crypto circles for its ZK Stack and zero-knowledge scaling work around Ethereum. In mid-2026, the company fully shifted its focus to Prividium’s institutional privacy infrastructure, following a skills realignment initiative inside the company.
What this means for banks and the market
For banks, the pitch is about cost and repeatability. If every tokenized deposit, payment or settlement product needs bespoke engineering, the economics rarely justify leaving the sandbox.
A shared control layer could change that math. Configure permissions and policies once, then reuse that framework for the next product.
The Cari Network launch is the clearest near-term test. A working multi-bank tokenized deposit platform with names like Huntington and M&T Bank would give Matter Labs a concrete answer to the skeptics.
For the Ethereum ecosystem, Prividium chains anchor to Ethereum through zero-knowledge proofs, meaning wider adoption would put more institutional activity behind Ethereum settlement, even if the transaction details never appear on the public chain.
Open-sourcing Prividium Core suggests the company sees an advantage in letting institutions inspect and test the permissioning engine themselves.
