ENTERPRISE-GRADE SECURITY
How We Protect Your Market Data
Our privacy-preserving oracles are engineered with a multi-layered security architecture, ensuring your sensitive financial data remains confidential, tamper-proof, and available. We protect your competitive edge.
01
Zero-Knowledge Proofs for Data Integrity
We cryptographically prove the validity of off-chain data without revealing the raw inputs. This allows your dApp to verify price accuracy while keeping the underlying data source and aggregation logic private from competitors.
zk-SNARKs
Proof System
No Raw Data
On-Chain Leakage
02
Trusted Execution Environments (TEEs)
Sensitive data aggregation and signing occur within hardware-isolated secure enclaves (e.g., Intel SGX). This prevents exposure to the host operating system, cloud provider, or even our own infrastructure operators.

Verified Integrity
03
Decentralized Data Sourcing & Aggregation
We source data from 50+ independent, high-quality CEXs and DEXs. Our proprietary aggregation logic runs off-chain in a decentralized node network, eliminating single points of failure and manipulation.

Cryptographic Signature Security
Each data feed update is signed by a decentralized threshold signature scheme (DKG). No single entity holds the signing key, requiring consensus among node operators to publish data, preventing rogue updates.

SLA-Backed Reliability & Uptime
We guarantee the availability and freshness of your data feeds with a financially-backed 99.9% uptime SLA. Our globally distributed node network ensures low-latency updates even during regional outages.

Our Development & Integration Process
A structured, transparent process designed to deliver production-ready, secure privacy-preserving oracles with minimal integration overhead for your team.
01
Requirement & Architecture Design
We conduct a technical deep-dive to map your specific data needs, threat model, and consensus requirements. We design a custom architecture selecting optimal ZK-proof systems (zk-SNARKs, zk-STARKs) and data attestation protocols.

Privacy Oracle Development FAQs
Get clear, specific answers to the most common questions CTOs and technical founders ask when evaluating a privacy-preserving oracle partner.
A standard privacy oracle deployment takes 2-4 weeks from kickoff to mainnet launch. This includes requirements finalization, smart contract development, zero-knowledge circuit design, on-chain deployment, and initial testing. Complex multi-chain or custom attestation logic can extend this to 6-8 weeks. We provide a detailed, phase-gated project plan at the start of every engagement.
