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 operational backbone of your dApp. Our development process is built on Solana, EVM, and Move-based chains, ensuring optimal performance for your specific use case. Every contract undergoes a rigorous multi-stage audit to eliminate vulnerabilities before mainnet deployment.
- Custom Logic & Architecture: Design and implement bespoke contract systems for DeFi, NFTs, gaming, and enterprise solutions.
- Security-First Development: Built with
Solidity 0.8+,Rust (Solana), orMove (Aptos/Sui)using established patterns fromOpenZeppelinandAnchor. - Comprehensive Auditing: Internal review, automated analysis, and optional third-party audit coordination for maximum security assurance.
- Gas Optimization: Expert tuning to reduce transaction costs by up to 40% and improve user experience.
We deliver fully documented, upgradeable contracts with a clear handoff, enabling your team to own and iterate on a secure foundation.

Frequently Asked Questions
Get answers to common questions about our Cairo-based private transaction development process, security, and support.
A standard, audited ZK-Mixer deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 2 weeks for core Cairo smart contract development, 1 week for integration and frontend, 2 weeks for security audits, and 1 week for final deployment and testing. Complex features like multi-asset support or custom withdrawal logic can extend the timeline.
