overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
Deliver a production-ready, gas-optimized contract suite in as little as 2 weeks.
Our full-service development includes:
- End-to-end lifecycle management: From specification and
Hardhat/Foundrydevelopment to deployment and monitoring. - Multi-protocol expertise: EVM (Ethereum, Polygon, Arbitrum),
SolanawithAnchor, andCosmos SDK. - Built-in security: Formal verification, automated testing, and pre-audit readiness for firms like CertiK or Trail of Bits.
We move beyond basic ERC-20 tokens to complex systems:
- DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators.
- NFT Ecosystems: Dynamic
ERC-721/ERC-1155contracts with advanced minting, staking, and royalty mechanics. - Enterprise Logic: Custom business logic for asset tokenization, supply chain, and governance.

ZK-Rollup Treasury Privacy
Frequently Asked Questions
Common questions from CTOs and technical leads evaluating our privacy module development service.
A standard deployment for a custom ZK-Rollup privacy module takes 4-8 weeks. This includes 2 weeks for architecture and circuit design, 3-4 weeks for development and internal testing, and 1-2 weeks for audit preparation. Complex integrations (e.g., multi-asset support, custom governance) can extend this timeline, which we scope and quote upfront.
