CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Full Lifecycle Development: From initial design and
Solidity/Rustdevelopment to deployment onEVM/Solanaand ongoing maintenance. - Security-First Approach: All code undergoes internal audits and follows
OpenZeppelinstandards before we recommend third-party verification. - Measurable Outcomes: Achieve 99.9% uptime SLAs, gas-optimized execution, and audit-ready code within a typical 3-6 week delivery cycle.

Frequently Asked Questions
Get clear answers on how our platform accelerates your cross-chain product development, from initial setup to long-term scaling.
A standard deployment for a production-ready, multi-chain user experience layer takes 2-4 weeks. This includes integrating 2-3 target rollups (e.g., Arbitrum, Optimism, zkSync), implementing our unified wallet and gas management SDKs, and setting up the initial monitoring dashboard. Complex integrations with custom L2s or advanced bridging logic can extend this to 6-8 weeks.
