ARCHITECTURE ENGINEERED FOR SCALE
Core Capabilities of Our Hybrid Rollup Service
We deliver a production-ready hybrid rollup infrastructure that combines the security of ZK proofs with the cost-efficiency of Validium. Our service is built for teams that need enterprise-grade performance without the operational overhead.
01
Customizable Data Availability Layer
Choose between on-chain (ZK/Optimistic) for maximum security or off-chain (Validium) for minimal transaction costs. We architect the optimal data availability solution for your application's risk and cost profile.

Hybrid Rollup Development: Key Questions
Answers to the most common technical and commercial questions we receive from teams evaluating a custom Hybrid Rollup (ZK/Optimistic + Validium) solution.
A standard Hybrid Rollup deployment, including core sequencer, prover/verifier setup, and data availability layer integration, takes 2-4 weeks from finalized spec to testnet launch. Complex protocols with custom fraud proofs or advanced ZK circuits may extend to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap on day one.
