PROVEN FRAMEWORK
Our Delivery Methodology
Our structured approach to ZK-Rollup Oracle Proof Aggregation ensures predictable delivery, enterprise-grade security, and seamless integration with your existing stack.
01
Architecture & Design Review
We conduct a deep-dive analysis of your rollup's data requirements and consensus model to design a custom aggregation circuit. This includes selecting optimal ZK-SNARK libraries (e.g., Halo2, Plonky2) and defining the proof verification logic for your specific oracles.

Frequently Asked Questions
Get clear answers on how our specialized service integrates with your L2 stack, from security to deployment.
A standard integration for a new rollup takes 3-5 weeks from kickoff to mainnet deployment. This includes 1 week for architecture design, 2-3 weeks for development and on-chain integration of our aggregator contract, and 1 week for security review and testing. For existing rollups, the timeline can be as short as 2 weeks for a modular integration.
