CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Custom Tokenomics: Design and implement
ERC-20,ERC-721, andERC-1155tokens with custom minting, vesting, and governance logic. - DeFi Protocols: Build automated market makers (AMMs), lending/borrowing pools, staking systems, and yield aggregators.
- Enterprise Logic: Develop multi-signature wallets, asset management systems, and cross-chain interoperability layers.
We deliver a complete development lifecycle: from initial spec and security review to deployment, verification, and post-launch monitoring. Our contracts are built to pass third-party audits by firms like CertiK and Trail of Bits.
Typical Deliverables: Fully documented source code, deployment scripts, a comprehensive test suite with >95% coverage, and a technical architecture whitepaper. We can deliver a production-ready MVP in as little as 2-4 weeks.

Frequently Asked Questions
Answers to common technical and commercial questions about our StarkNet ZK-Rollup development services.
A standard ZK-Rollup deployment on StarkNet takes 2-4 weeks from finalized specification to mainnet launch. This includes development, rigorous internal testing, and deployment of the core sequencer and prover infrastructure. Complex integrations (e.g., custom bridges, multi-asset support) can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping phase.
