METHODOLOGY
Our Implementation Process
A structured, four-phase approach to deliver a production-ready, secure, and scalable privacy-preserving oracle network tailored to your specific data and compliance requirements.
01
Phase 1: Architecture & Threat Modeling
We design your network's zero-knowledge proof (ZKP) circuit architecture and threat model, selecting optimal frameworks (zk-SNARKs, zk-STARKs) and defining data privacy guarantees. This phase establishes the cryptographic foundation and security parameters.
1-2 weeks
Design Sprint

Phase 2: ZK Circuit & Node Development
Our team builds the core privacy layer: custom ZK circuits for data attestation and the validator node software. We implement MPC/TEE-based key management and ensure gas-efficient on-chain verification contracts.

Phase 3: Security Audit & Testing
Every component undergoes rigorous review. ZK circuits are formally verified; smart contracts are audited against reentrancy and oracle manipulation attacks. We conduct adversarial simulations in a testnet environment.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by experts to power your Web3 application.
We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, and NFTs. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and cross-chain bridges.
We deliver a fully tested, documented, and deployable contract suite in 2-4 weeks for a standard MVP.
Our code undergoes internal security reviews and is structured for seamless integration with frontends and indexers. We provide a clear roadmap for third-party audits with firms like CertiK or Quantstamp.

Frequently Asked Questions
Get clear answers on our process, security, and timelines for implementing confidential oracle infrastructure.
A privacy-preserving oracle is a decentralized data feed that delivers verified, real-world information to smart contracts without exposing the underlying sensitive data or the computation logic. You need one to build DeFi, gaming, or enterprise dApps that require confidential inputs (e.g., private asset prices, KYC status, proprietary trading signals) while maintaining the trustless guarantees of blockchain. Our setup prevents front-running, protects user data, and enables new use cases like private auctions and compliant DeFi.
