CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production from day one.
- Production-Ready Code: Built with
Solidity 0.8+,OpenZeppelinlibraries, and comprehensive testing suites. - Gas Optimization: Every line is analyzed for efficiency, reducing user transaction costs by 15-40%.
- Security Audits: All contracts undergo internal review and can be prepared for third-party audits from firms like Quantstamp or CertiK.
- Full Lifecycle Support: From initial design and development to deployment, verification, and ongoing maintenance on EVM-compatible chains.
We deliver contracts you can stake your business on, with a focus on security, efficiency, and long-term maintainability.

Frequently Asked Questions on L2 Migration
Get clear, specific answers to the most common questions CTOs and technical leads ask when evaluating an L2 migration partner.
A standard migration from Ethereum mainnet to an L2 like Arbitrum or Optimism takes 2-4 weeks from kickoff to mainnet deployment. This includes contract refactoring, testing, and deployment. Complex protocols with custom bridges or multi-chain logic may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during the scoping phase.
