A PROVEN FRAMEWORK
Our Delivery Methodology: From Architecture to Integration
We deliver production-ready mobile oracle solutions through a structured, four-phase process designed for security, speed, and seamless integration into your existing stack.
01
1. Architecture & Threat Modeling
We design a secure, privacy-preserving oracle architecture tailored to your mobile app's data needs. This includes threat modeling for mobile-specific attack vectors and defining the optimal on-chain/off-chain data flow.

Frequently Asked Questions on Privacy-Preserving Oracles
Get clear answers on integrating secure, private data feeds into your mobile or on-chain applications. These FAQs cover timelines, costs, security, and our proven delivery process.
A standard integration for a single data feed (e.g., price feeds) takes 2-3 weeks from kickoff to production deployment. Complex integrations with multiple custom data sources, advanced ZK-proof circuits, or multi-chain support typically require 4-8 weeks. We provide a detailed project plan with weekly milestones after the initial technical scoping session.
