FROM ASSESSMENT TO PRODUCTION
Our Implementation Process
A structured, security-first approach to integrating privacy-preserving oracles into your DePIN data pipeline. We deliver a production-ready solution with clear SLAs and minimal disruption to your existing operations.
01
1. Architecture & Threat Modeling
We conduct a deep-dive analysis of your data sources, on-chain/off-chain workflows, and compliance requirements. This phase defines the cryptographic primitives (ZKPs, MPC, FHE) and trust model for your specific use case.

Privacy-Preserving Oracle for DePIN
Frequently Asked Questions
Get clear answers on how our oracle secures sensitive DePIN data, from integration to long-term support.
We implement a multi-layered privacy architecture. Data is encrypted end-to-end using zero-knowledge proofs (ZKPs) for on-chain verification without exposing raw data. Our oracles run in secure enclaves (TEEs) for tamper-proof computation, and we use decentralized identifiers (DIDs) to anonymize data sources. This ensures data like energy consumption, device health, or location is usable for smart contracts without compromising user or operator privacy.
