CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Every contract undergoes internal audits and is built with established security patterns to mitigate reentrancy, overflow, and access control risks.
- Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
- Full Lifecycle Support: From initial architecture and
Hardhat/Foundrytesting to deployment onEVM-compatible chains and mainnet verification.
Deliver a secure, auditable foundation for your product in 2-4 weeks, not months. We ensure your core logic is battle-tested before a single user interacts with it.

Frequently Asked Questions
Get clear, technical answers to common questions about integrating a ZK-Rollup payment layer with StarkNet.
A complete integration, from smart contract development to mainnet deployment, typically takes 4-8 weeks. This includes 1-2 weeks for architecture & design, 2-4 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. Complex protocols with custom logic or novel tokenomics may extend this timeline.
