CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial design and
Solidity 0.8+coding to deployment, verification, and ongoing maintenance. - Security-First Approach: Every contract undergoes internal audits and follows
OpenZeppelinstandards before submission to top-tier third-party auditors. - Gas Optimization: We write efficient code to minimize transaction costs and maximize user savings, critical for high-volume applications.
Deliver a secure, audited, and fully functional smart contract suite in as little as 2-4 weeks, accelerating your time-to-market while mitigating technical and financial risk.

Frequently Asked Questions
Get clear answers on our development process, security, and support for building secure, real-time data pipelines.
For a standard, production-ready Private Data Stream API with SDKs, the typical timeline is 4-8 weeks. This includes requirements analysis, architecture design, core API development, multi-language SDK creation (e.g., TypeScript/Node.js, Python, Go), comprehensive testing, and deployment. Complex integrations with multiple data sources or custom consensus mechanisms can extend this to 10-12 weeks. We provide a detailed project plan with milestones after the initial discovery phase.
