ZK Stack
The ZK Stack is an open-source framework for building customizable, enterprise-grade ZK blockchains that scale globally, interoperate natively, and inherit Ethereum's security.

Performance at scale
ZK Stack chains can process 15K+ TPS (~0.75 Ggas/s), powered by Airbender, an open-source RISC-V prover optimized for speed and cost efficiency. A high-performance sequencer provides consistent throughput, low latency, and production-grade reliability. Chains interoperate trustlessly and scale horizontally.
Fully customizable
ZK Stack chains are built on a modular architecture. Out of the box you can define a custom gas token, enable zero-fee transactions, choose a data availability layer, set chains as public, private, or permissioned, and select an MEV policy.
Fast time to market
ZK Stack comes with everything you need pre-integrated: Ethereum settlement, enterprise wallets, observability, on-ramps, and role-based permissioning. Matter Labs also offers rollup-as-a-service, a one-stop solution to host and operate your chain so you can launch quickly without the overhead of running infrastructure.
Battle-tested security
$10M+ invested in security, including 35+ external audits, 4 public audit contests, and an ongoing bug bounty program paying up to $1.1M.
Future-proof technology
As the industry migrates from fraud to ZK proofs, ZK Stack chains are already running on proven ZK infrastructure. Enterprises avoid costly migrations, stay aligned with Ethereum's roadmap, and gain quantum compute-resistant security.

Abstract: The blockchain leading the next generation of consumer crypto
Abstract chose ZK Stack to power consumer applications at scale. Their priorities were predictable low costs unaffected by high throughput and avoiding the complexity of blockchain operations. By using Matter Labs' rollup-as-a-service, Abstract can fully focus on customers while Matter Labs operates the infrastructure.
GRVT: Decentralized derivatives exchange
GRVT chose ZK Stack to launch on a permissioned, KYC-enabled blockchain with the flexibility to relax restrictions over time. The system combines on- and off-chain computation to process 600k+ trades in under 2ms, while settling onchain as frequently as possible. GRVT also operates with a zero-fee configuration.
Deutsche Bank: On chain fund management with strict privacy and compliance
Memento deployed a Prividium™ for Deutsche Bank under Project Guardian (MAS) using the ZK Stack. The project simplifies and accelerates asset tokenization and fund operations, reducing complexity and costs.
Sophon.xyz: Next-generation gaming and entertainment ecosystem
Sophon is building a gaming and entertainment hub on ZK Stack. By combining Ethereum settlement with instant interoperability, Sophon delivers a seamless player experience while supporting high-throughput game economies.
Frequently asked questions
Everything you need to know about ZK Stack.
Running an L1 means maintaining a distributed validator set. This is costly as the validators need to be incentivized. This also means chain owners don’t maintain control over the chain. With ZK Stack you keep full control of your chain while inheriting Ethereum, the most decentralized blockchain, security out of the box.
We prioritize based on partner needs. If your chain requires it, we'll deliver. Our focus is enabling your GTM.
No. Your chain inherits Ethereum's security while using a single operator or sequencer of your choice.
Q2 2025 pre-optimization benchmarks show ~$0.0002 per transaction. Costs stay an order of magnitude lower than optimistic rollups.
Matter Labs maintains a blockchain hosting service. We can host the chain for you. If you prefer to self-host, we maintain several enterprise-grade support tiers. Our goal is to take care of the blockchain for you while you focus on your users.
