CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by engineers who have deployed over 100 contracts to mainnet.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control, upgradeable proxy patterns, and cross-chain bridges.
We deliver battle-tested contracts with a focus on gas optimization and security-first design, reducing your audit costs and mitigating on-chain risk from day one.

PROVEN METHODOLOGY
Our Development Process
A structured, security-first approach to deliver production-ready EVM-compatible privacy L2s. We de-risk your launch with battle-tested protocols and clear deliverables at every stage.
01
Architecture & Protocol Design
We define your L2's core privacy architecture, selecting the optimal ZK-SNARK/STARK framework (e.g., zkSync, Starknet) and data availability layer. This phase establishes the foundation for scalability and compliance.

Frequently Asked Questions
Get clear answers on timelines, costs, security, and process for building a private Layer 2 solution.
A standard deployment with core privacy features (confidential transactions, shielded pools) takes 4-6 weeks from kickoff to testnet. Complex integrations, custom ZK-circuits, or multi-chain bridges can extend this to 8-12 weeks. Our agile process includes weekly demos and a clear milestone-based roadmap.
