Why Founders and CTOs Choose Our Audits
We deliver more than a compliance check. Our ZK-Rollup audits are engineered to de-risk your core infrastructure, protect user funds, and provide the technical confidence needed to scale.
01
Proven ZK Circuit & State Transition Expertise
Our team has audited over 50 ZK circuits and state transition logic for major rollups. We find critical vulnerabilities in custom proving systems, recursive proofs, and Merkle tree implementations that generic auditors miss.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our development process is built on audited security patterns and delivers contracts that are gas-optimized and upgradeable from day one.
- Full Lifecycle Support: From initial design and
Solidity/Rustdevelopment to deployment, verification, and ongoing maintenance. - Security-First: Every contract undergoes internal review against OpenZeppelin standards and is prepared for third-party audits.
- Measurable Outcomes: Achieve >99.9% uptime, reduce gas costs by 15-40%, and launch your MVP in 2-4 weeks.
We don't just write code; we deliver the secure, scalable foundation your Web3 product needs to succeed.
Our engineers specialize in:
- DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators, and automated strategies.
- Digital Assets: Custom
ERC-20,ERC-721, andERC-1155tokens with advanced minting and royalty logic. - Governance & DAOs: Voting systems, treasury management, and proposal frameworks using
OpenZeppelin Governor. - Enterprise Integration: Bridging off-chain data with
Chainlinkoracles and building compliant access controls.

ZK-Rollup Security & Recovery FAQs
Common questions from CTOs and technical founders evaluating the security and resilience of their ZK-Rollup infrastructure.
Our standard ZK-Rollup Data Integrity & Recovery Audit is a 3-4 week engagement. It includes a comprehensive review of your circuit logic (Cairo, Noir, Circom), sequencer and prover code, data availability layer integration, and the full recovery mechanism. We deliver a prioritized vulnerability report with proof-of-concept exploits and provide a remediation review. For complex, high-value protocols (e.g., >$100M TVL), we recommend a 5-6 week deep-dive audit.
