Smart Contract Development
Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.
We architect and deploy production-grade smart contracts that are secure, gas-optimized, and upgradeable. Our process delivers audit-ready code from day one, built on Solidity 0.8+ with OpenZeppelin standards and comprehensive testing suites.
- Security-First Development: Every contract undergoes rigorous internal review and formal verification before external audit, mitigating risks like reentrancy and overflow.
- Gas Optimization: We reduce transaction costs by 20-40% through efficient data structures and contract architecture.
- Upgradeability & Maintenance: Implement
Transparent ProxyorUUPSpatterns for seamless, secure future upgrades without migrating state.
Your Migration Questions, Answered
ZK Migration FAQs
Get clear answers on timelines, costs, and technical details for migrating from legacy ZK systems like zkSync Classic or Polygon Hermez.
A standard migration from a legacy ZK system (e.g., zkSync Classic) to a modern ZK stack (e.g., zkSync Era, Polygon zkEVM) takes 2-4 weeks from kickoff to mainnet deployment. This includes architecture review, smart contract porting, circuit optimization, and security audits. Complex protocols with custom circuits may extend to 6-8 weeks.
