TLDR
Across now supports ZKsync's ZK Stack, completing its integration across all major L2 frameworks (OP Stack, Arbitrum Orbit, ZK Stack). Starting with Lens, this integration makes Across the first Intents-based bridge to support ZK Stack. Developers can now build seamless, efficient crosschain apps that unify L2 liquidity and enable scalable interoperability across Ethereum’s ecosystem.
Introduction
Imagine a crosschain future powered by Intents and ZK-proofs. We’re pleased to announce that this future is now possible thanks to Across’ integration with ZKsync’s ZK Stack.
This groundbreaking integration completes our coverage of the most prominent L2 frameworks: OP Stack/Superchain, Arbitrum Orbit, and ZK Stack—a pivotal expansion, starting with our integration with Lens.
Let's explore ZK Stack, how Across enhances its ecosystem, and why the expansion is a game-changer for L2 developers building on the cutting edge of crosschain interoperability.
What is ZK Stack?
ZK Stack is a developer-friendly modular framework that makes it easy for you to customize and deploy your own interoperable ZK-powered L2.
With 30 million monthly transactions, ZK Stack’s battle-tested infrastructure already powers a high-throughput network designed for internet-scale applications. By leveraging ZK-proofs, ZK Stack prioritizes both security and scalability while fostering shared liquidity and user bases across its ecosystem.
Technical Implementation: Lens Integration
Across' support for ZK Stack is made possible through its integration with Lens, an EVM-compatible Validium chain built on ZKsync and developed by Avara—the team behind Aave. As Across' first integration with a ZK Stack chain, our deployment on Lens lays the groundwork for seamless future integrations with other ZK Stack chains. Now that we've bridged to one ZK Stack chain, we can easily bridge to more chains.
Scaling ZK Stack Connectivity with Lens
By integrating with Lens, Across enables seamless crosschain transactions between ZK Stack and the broader L2 ecosystem. Developers can leverage ZK Stack’s scalable ZK-powered networks while maintaining connectivity with existing L2 frameworks, enhancing interoperability between ZK and optimistic rollups for more efficient crosschain liquidity movement.
Unifying L2 Liquidity Through Crosschain Intents
Across’ integration with ZK Stack unifies L2 liquidity through standardized crosschain Intents. As L2 networks evolve, fragmentation still remains a challenge—but we’re committed to solving it. By supporting ZK Stack and other emerging L2 frameworks, we’re laying the foundation for a truly unified Ethereum.
Across unites chains between the OP Superchain, Arbitrum Orbit, and ZK Stack ecosystems.
Crosschain Interoperability: Powered by Intents
Across leverages an Intents-based architecture to seamlessly integrate ZK stack’s Validium chains, making it the first Intents-based bridge to support ZK Stack. This approach unlocks:
Optimized settlement paths for more efficient crosschain transactions.
Reduced operational costs by streamlining crosschain transaction execution.
Improved transaction speeds through automated Intent resolution.
With this integration, developers gain access to Across’ Intents-powered bridging infrastructure, optimizing liquidity movement and execution across L2s like never before—starting with the Lens ecosystem.
Crosschain Intents provide optimized settlement paths, reduced operational costs, and improved transaction speeds.
