Business Outcomes for Your Protocol
Our zero-knowledge oracle services translate into concrete, measurable advantages for your decentralized application. We focus on delivering the infrastructure that directly impacts your protocol's security, performance, and market position.
02
Reduced On-Chain Gas Costs
Submit a single ZK proof to the blockchain instead of voluminous raw data. This compresses transaction payloads, slashing gas fees by up to 90% for data-heavy operations like complex financial settlements or on-chain gaming logic.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process ensures security-first design, gas optimization, and compliance with industry standards like ERC-20, ERC-721, and ERC-1155.
- End-to-End Development: From specification and
Solidity/Rustcoding to testing and mainnet deployment. - Security Audits: Integration of OpenZeppelin libraries and preparation for third-party audits.
- Gas Optimization: Code reviews to minimize transaction costs and maximize user efficiency.
- Upgradeability: Implementation of proxy patterns (e.g., UUPS/Transparent) for seamless future upgrades.
We deliver auditable, high-performance contracts that reduce your time-to-market from months to weeks.

Frequently Asked Questions
Get clear, technical answers about our zero-knowledge oracle development, security, and deployment process.
From initial scoping to mainnet deployment, a standard zero-knowledge oracle integration takes 4-8 weeks. This includes 1-2 weeks for design and specification, 2-4 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. Complex multi-chain or high-frequency data feeds may extend this timeline.
