ENGINE ARCHITECTURE
Core Engine Capabilities We Build
We deliver production-ready, high-performance ZK query engines for EVM chains. Our modular architecture ensures scalability, security, and seamless integration into your existing data stack.
02
High-Performance Indexer & Prover
Our engine includes a dedicated indexer for real-time EVM chain syncing and a distributed prover network. We achieve sub-2 second proof generation for complex queries, ensuring low-latency data verification.

MONETIZE YOUR DATA
Business Outcomes for Data Providers
Our EVM-Based ZK Data Query Engine transforms your on-chain data into a secure, scalable revenue stream. We handle the complex infrastructure so you can focus on growth.
01
New Revenue Streams
Monetize proprietary on-chain data feeds (e.g., MEV signals, liquidity patterns) with privacy-preserving queries. We build the query marketplace and payment rails.
