Matter Labs
Builds zkSync, an open-source ZK rollup scaling Ethereum with zero-knowledge proofs for fast, low-cost transactions
About
Matter Labs is the team behind ZKsync, a network of chains secured by cryptography rather than validators. The stack includes ZKsync Era (their L2 rollup), ZK Stack (open-source framework for building ZK blockchains), Prividium (Ethereum-secured blockchain for institutions needing privacy and compliance), ZKsync Connect (interoperability protocol), and Airbender, a RISC-V prover that produces sub-second block proofs.
The network spans 18 chains, has secured over $4B in TVL, and processed 700M+ transactions. Integrations and customers include Chainlink, Circle, Fireblocks, Fidelity, and Deutsche Bank (asset tokenization via Memento).
The company describes itself as an engineering team passionate about liberty, blockchain, and math.
