ZK-ROLLUP ORACLE INFRASTRUCTURE
Architecture for Private Verification
We design and deploy secure, scalable architectures that enable your oracle to deliver verifiable data to ZK-rollups without exposing sensitive inputs or compromising user privacy.
01
Zero-Knowledge Proof Integration
Integrate ZK-SNARKs or ZK-STARKs to prove the correctness of off-chain data computations. We handle the complex circuit design and proof generation, ensuring your oracle's attestations are private and verifiable on-chain.

Secure Off-Chain Computation Layer
Deploy a hardened, containerized execution environment for your oracle logic. We implement secure multi-party computation (MPC) patterns and TLSNotary proofs to cryptographically guarantee data source integrity before proof generation.

Frequently Asked Questions
Get clear answers on our process, security, and timelines for implementing a privacy-preserving oracle solution.
A standard deployment for a privacy-preserving oracle setup takes 4-6 weeks from kickoff to mainnet launch. This includes 1 week for design and architecture, 2-3 weeks for core development and integration, and 1-2 weeks for security audits and final testing. Complex integrations with custom proving circuits or multi-chain support can extend this timeline.
