The company behind ZKsync

Matter Labs builds ZKsync

What is Matter Labs

Matter Labs is the engineering company that builds ZKsync, a network of blockchains secured by zero-knowledge cryptography, not validators.

We use ZK proofs to scale Ethereum and to give institutions privacy and compliance without leaving Ethereum's security umbrella. Our enterprise platform, Prividium®, enables banks and financial institutions to seamlessly come onchain and compete in the digital assets economy.

For banks & financial institutions

The Bank Stack of Ethereum

Prividium® is an Ethereum-secured blockchain platform purpose-built for institutions that demand privacy, compliance, and full control of their data.

Private where it matters. Connected where it counts.

Private by design

Run a private, permissioned chain in your own infrastructure or cloud. Sensitive data never leaves your environment; ZK proofs certify correctness without exposing it.

Audit-ready by design

Role-based access, selective disclosure for AML/KYC, and proof of reserves on demand. SOC 2.

Final on Ethereum

Every transaction anchors to Ethereum for settlement finality and security: no third-party trust, no bridges.

Frequently asked questions

Matter Labs is the engineering company that builds ZKsync, a network of blockchains secured by zero-knowledge cryptography that scales Ethereum. Prividium is our enterprise platform that brings privacy and compliance to banks and financial institutions.

Matter Labs is the company; ZKsync is the technology and network it builds. When you read about ZKsync's scaling, performance, or enterprise features, that's Matter Labs' work.

Prividium is ZKsync's enterprise platform: a private, permissioned blockchain you run in your own infrastructure, with every transaction anchored to Ethereum for finality. It keeps your data private, your auditors satisfied, and settlement final.

ZKsync inherits Ethereum's security and uses zero-knowledge proofs to guarantee that every transaction is valid. Its open-source code is independently audited, and it runs a public bug-bounty program.

Yes. Prividium is purpose-built for regulated institutions (banks, asset managers, and payment operators in the US, UK, and EU) that need privacy, compliance, and Ethereum-grade settlement.

ZKsync is open source and built on the ZK Stack. Start at the developer docs (docs.zksync.io) to deploy on ZKsync Era or launch your own ZK chain.
