CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From token standards to complex DeFi logic, we deliver contracts that are gas-optimized, upgradeable, and battle-tested.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and staking logic. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, DAO governance modules, and cross-chain bridges.
- Full Audit Trail: Code review,
Slither/MythXanalysis, and third-party audit coordination.

PROVEN PROCESS
Our Development Methodology
Our systematic approach to ZK Data Marketplace development ensures security, scalability, and rapid time-to-market. We deliver production-ready core protocols, not just prototypes.
01
Architecture & Design
We design the core protocol architecture, including data schemas, ZK proof circuits, and smart contract interfaces. This phase establishes the foundation for secure, scalable data exchange.

Technical & Commercial Insights
ZK Data Marketplace Protocol FAQ
Common questions from CTOs and technical founders about building a secure, scalable data marketplace with zero-knowledge proofs.
A production-ready ZK Data Marketplace Core Protocol typically takes 6-12 weeks for a complete build, audit, and deployment. This includes protocol design, smart contract development, ZK circuit implementation, and frontend integration. Pricing is project-based, with standard deployments starting at $80,000. Complex requirements, such as custom incentive models or multi-chain support, scale accordingly. We provide a detailed proposal after a technical scoping session.
