Matter Labs

Market position

Matter Labs is one of the companies working on Ethereum Layer 2 scaling, an area in which zkSync gained traction in the crypto ecosystem; by late 2022 approximately 150 projects had used zkSync in some form, including Chainlink, SushiSwap, Uniswap, Aave, Argent, 1inch, Gnosis and Curve. A secondary source lists Optimism, StarkWare, Polygon, Consensys and Offchain Labs as comparable companies. Its investor base includes Andreessen Horowitz, Blockchain Capital, Dragonfly, Union Square Ventures, Lightspeed Venture Partners and Placeholder.

Matter Labs describes Prividium as the only Ethereum-secured blockchain platform purpose-built for institutions requiring privacy, compliance and full control of their data. Its stated design combines a private, permissioned chain hosted in the customer's own environment — so sensitive data does not leave that environment — with zero-knowledge proofs certifying correctness, role-based access, selective disclosure for AML/KYC, on-demand proof of reserves, and direct anchoring to Ethereum for settlement without bridges or third-party trust. The core stack is open source and independently audited, and the platform has undergone a SOC 2 Type I examination.

Technology

The company's technology is based on zero-knowledge proofs. zkSync is a zero-knowledge rollup: transactions are processed and batched by Layer 2 nodes, validity proofs are generated over hundreds of transactions, and those proofs are posted to the Ethereum mainnet, making the batched transactions unalterable. The rollup release described in 2022 was to be Ethereum Virtual Machine compatible so that decentralized applications could be ported with minimal work. The ZK Stack is an open-source framework for launching customizable Ethereum-secured ZK chains. Prividium applies the same stack in a private, permissioned configuration with role-based access, selective disclosure for AML/KYC and proof of reserves. Atlas and the Airbender prover are stated to target ~1-second finality and up to 15,000 TPS with proofs generated in seconds.

Go-to-market

For Prividium, Matter Labs sells directly to regulated institutions, inviting prospective customers to contact its team for a platform walkthrough and an architecture review for their use case, with public technical documentation at docs.zksync.io available for independent engineering evaluation. In the public-network business, adoption is driven by open-source distribution of the ZK Stack and integration by third-party crypto projects; a $200 million ecosystem fund was established to foster zkSync adoption. The organization includes dedicated sales, marketing, ecosystem success, business partnering and developer relations functions.

Regulated financial institutions — banks, asset managers, fund administrators and payment operators — that require privacy, compliance and Ethereum-grade settlement, as well as developers and crypto projects building on the ZK Stack and the public ZKsync network.

Geography

Headquartered in George Town, Cayman Islands.

History

Sources give differing founding dates; one secondary account places the founding in 2018 by Alex Gluchowski and Alexandr Vlasov, with a seed round on 11 September 2019, a Series A in March 2021, a $50 million Series B in November 2021 and a $200 million Series C announced on 16 November 2022. The company's work initially centered on zkSync as an Ethereum Layer 2 scaling solution; by the time of the Series C, zkSync's forthcoming release was to be EVM-compatible and Matter Labs planned to open-source zkSync 2.0 under an MIT license. The company has since positioned Prividium, an enterprise, permissioned deployment of the same zero-knowledge technology, as its platform for banks and financial institutions, and has completed a SOC 2 Type I examination for it.

Risks & controversies

The November 2022 Series C was announced amid uncertainty in the crypto sector following the collapse of FTX. Ethereum co-founder Vitalik Buterin publicly noted the risk that a ZK-rollup holding large sums could be exploited through a bug in circuit constraint code or an EVM wrapper, a concern Matter Labs' plan to open-source zkSync 2.0 was intended to help address.
