CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your project. Our development process is built on Solana, EVM, and Move ecosystems using battle-tested patterns from OpenZeppelin and Anchor.
- Full lifecycle support: From initial design and
Solidity/Rustdevelopment to deployment and mainnet launch. - Security-first approach: Every line undergoes internal review and is prepared for formal audits by firms like CertiK or Quantstamp.
- Gas optimization: We write efficient code to minimize transaction costs and maximize user savings.
Deploy a secure, audited MVP in as little as 2-4 weeks, not months.
Our deliverables are production-grade from day one:
- Complete, well-commented source code in
Git. - Comprehensive test suites with >95% coverage.
- Deployment scripts and verification for
Etherscan/Solscan. - Technical documentation for your team and future auditors.

Fraud Proof Verification FAQs
Get clear, expert answers to the most common questions about implementing and scaling fraud proof verification for your Optimistic Rollup.
A complete, production-ready fraud proof verification system typically takes 4-8 weeks from kickoff to mainnet deployment. This includes architecture design, smart contract development, integration with your sequencer, and rigorous security testing. For simpler integrations or proof-of-concepts, timelines can be as short as 2-3 weeks.
