CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by experts for your Web3 application.
- Full Lifecycle Development: From initial architecture and
Solidity/Rustcoding to deployment and post-launch maintenance. - Security-First Approach: Every contract undergoes internal audits and formal verification, leveraging libraries like
OpenZeppelin. - Protocol Integration: Seamless integration with major standards (
ERC-20,ERC-721,ERC-1155) and DeFi primitives (Uniswap V3, Aave).
Deploy a battle-tested, gas-optimized MVP in as little as 2-3 weeks, not months. We focus on delivering a secure foundation so you can scale with confidence.

Frequently Asked Questions
Get clear answers on our process, security, timelines, and support for building custom ZK-Rollup vaults on zkSync Era.
A standard, production-ready vault with core deposit/withdraw and yield strategies takes 4-6 weeks from kickoff to mainnet deployment. Complex multi-strategy vaults or those requiring custom ZK circuit logic can extend to 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial scoping session.
