DELIVERABLES & GUARANTEES
Business Outcomes for Your Project
Our privacy-preserving oracle development delivers verifiable, production-ready infrastructure with clear SLAs and security guarantees. We focus on measurable outcomes that accelerate your go-to-market and de-risk your data pipeline.
01
Secure, Verifiable Data Feeds
We deliver custom oracle nodes with zero-knowledge proofs (ZKPs) or trusted execution environments (TEEs) to fetch and attest to off-chain data without exposing sensitive inputs or logic. This enables DeFi, gaming, and enterprise applications to use private data on-chain.

A PROVEN FRAMEWORK
Our Development & Integration Process
From initial design to mainnet deployment, our structured process ensures your privacy-preserving oracle is delivered on time, on budget, and with enterprise-grade security.
01
Requirement & Architecture Design
We conduct deep technical workshops to define your data needs, threat model, and integration points. Deliverables include a detailed technical specification and architecture diagram for the zero-knowledge proof (ZKP) circuit and oracle node logic.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom Solidity and Rust smart contracts that form the secure backbone of your application. Our development process is built on OpenZeppelin standards and includes formal verification for critical logic.
- Security-First Development: Every contract undergoes manual review and automated analysis with tools like Slither and MythX before deployment.
- Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol economics.
- Full Audit Support: We prepare comprehensive technical documentation and test suites to streamline third-party audits with firms like Trail of Bits or Quantstamp.
Deliver a battle-tested, auditable smart contract system in 4-6 weeks, from specification to testnet deployment.
