CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing platforms.
- Security First: Every contract follows best practices for reentrancy, overflow, and access control vulnerabilities.
- Full Ownership: You receive all source code, audit reports, and deployment control.
We turn your protocol design into battle-tested, gas-optimized code with a 2-4 week MVP timeline.

SECURITY BY DESIGN
Architected for Enterprise Confidentiality
Our ZK-Rollup Privacy Layer is engineered from the ground up to meet the stringent security and compliance requirements of B2B financial transactions, ensuring data sovereignty and regulatory adherence.
01
Zero-Knowledge Proofs for Data Privacy
Transaction details and counterparty identities are cryptographically shielded on-chain. Only authorized participants can decrypt relevant data, ensuring complete confidentiality for sensitive B2B deals.

PREDICTABLE, SECURE, AND SCALABLE
Our Delivery Process: From Audit to Mainnet
A structured, milestone-driven approach to deliver a production-ready ZK-Rollup privacy layer. We de-risk your B2B transaction project with clear deliverables, expert oversight, and guaranteed outcomes at every stage.
01
1. Architecture & Security Audit
We begin with a comprehensive review of your existing transaction logic and data privacy requirements. Our team maps out the optimal ZK-Rollup architecture (zkSync, StarkNet, Polygon zkEVM) and performs a threat model analysis to identify risks before a single line of code is written.
Deliverable: Detailed technical specification and security audit report.

2. Circuit Design & Smart Contract Development
Our cryptographers design custom zero-knowledge circuits for your specific B2B transaction logic (e.g., confidential balances, selective disclosure). Concurrently, our Solidity/Vyper developers build the core rollup smart contracts, bridge, and prover/verifier logic on your chosen L1.
Deliverable: Audited circuit code and smart contract suite ready for testnet.

3. Rigorous Testing & Penetration Audit
We deploy the complete system to a private testnet for exhaustive integration, load, and edge-case testing. An independent, third-party security firm (e.g., Trail of Bits, Quantstamp) conducts a formal penetration audit on the circuits and contracts. All findings are remediated before proceeding.
Deliverable: Full audit report and a stable, bug-bountied testnet deployment.

ZK-Rollup Privacy Layer: Key Questions
Get clear, specific answers to the most common questions from technical leaders evaluating a private ZK-Rollup solution for their business.
A standard deployment for a custom ZK-Rollup privacy layer takes 2-4 weeks from kickoff to mainnet launch. This includes circuit design, smart contract development, integration with your existing stack, and security audits. Complex requirements like custom proof systems or multi-chain interoperability can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
