# Matter Labs

> Matter Labs is the engineering company that builds Prividium®, the Ethereum-secured blockchain platform for banks and financial institutions. Prividium runs as a private, permissioned chain inside an institution's own infrastructure, with every transaction anchored to Ethereum for settlement finality. Matter Labs also builds ZKsync, the public zero-knowledge network based on the same technology.

## Prividium (flagship platform)

- [Prividium](https://matterlabs.com/prividium): The only 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.
- Privacy: transactions execute inside the institution's infrastructure; only zero-knowledge proofs are published to Ethereum, never transaction data, counterparties, or balances.
- Compliance: role-based access control, selective disclosure for AML/KYC, sanctions checks, and proof of reserves on demand.
- Assurance: SOC 2 Type I examination completed by Thoropass Assurance against the AICPA Trust Services Criteria (Security, Availability, Confidentiality, Privacy), as of May 29, 2026.
- Use cases: tokenized deposits and programmable bank money, cross-border payments, tokenized asset issuance, KYC-anchored markets, atomic swaps (DvP/PvP), intraday repo.

## Technology

- [ZK Stack](https://www.zksync.io/zk-stack): The open-source framework Prividium chains are built on.
- [Atlas + Airbender](https://www.zksync.io/airbender): The sequencer and prover stack, with proofs generated in seconds.
- [ZKsync Connect](https://www.zksync.io/zksync-connect): ZK-secured interoperability and atomic settlement across public and private systems, with no bridges.
- [ZKsync](https://www.zksync.io): The public network of chains built on the same technology, secured by cryptography, not validators.

## Key facts

- Matter Labs is the company; Prividium is its enterprise blockchain platform for regulated institutions; ZKsync is the public zero-knowledge network built on the same ZK Stack.
- Prividium® is a registered trademark of Matter Labs in the United States.
- Prividium is a validium: transaction data stays off-chain in the operator's infrastructure while validity proofs settle on Ethereum.
- Everything is grounded in open-source cryptography and Ethereum's security.
