Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy audited, gas-optimized smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, leveraging battle-tested patterns from OpenZeppelin and rigorous testing frameworks like Hardhat and Foundry.
Reduce your time-to-market from months to weeks with our proven development lifecycle.
Solidity 0.8+/Vyper contracts for DeFi, NFTs, DAOs, and enterprise use cases.Goerli, Sepolia) to mainnet deployment and verification.We deliver a complete technical package: source code, comprehensive documentation, and a deployment roadmap. This eliminates infrastructure risk and lets your team focus on product growth, not protocol vulnerabilities.
Our systematic, multi-layered approach ensures your privacy protocol is secure, compliant, and ready for production. We deliver actionable reports, not just a checklist.
We analyze the core ring signature implementation (e.g., MLSAG, CLSAG, Lelantus) for mathematical soundness, key management, and integration with your application's architecture to prevent systemic flaws.
Leveraging proprietary and industry-standard tools (Slither, MythX) to detect common vulnerabilities like signature malleability, replay attacks, and gas inefficiencies in your Solidity/Rust code.
Our senior cryptographers perform line-by-line analysis of critical functions—signature generation, verification, and linkability—focusing on edge cases and logical errors automated tools miss.
We simulate real-world attack scenarios, including front-running, Sybil attacks, and deanonymization attempts, to test the protocol's resilience under adversarial conditions.
Alignment review with regulatory considerations (e.g., OFAC, Travel Rule readiness) and adherence to industry best practices for privacy-preserving systems.
We provide clear, prioritized findings and work directly with your team to verify fixes. Includes a final re-audit of critical issues to ensure resolution before mainnet deployment.
Generic audits miss the nuanced cryptographic vulnerabilities in privacy-preserving protocols. Our specialized review targets the unique risks of ring signatures, mixers, and zero-knowledge applications to ensure your anonymity set is mathematically sound.
Audit the logic managing decoys and ring formation to prevent statistical analysis and timing attacks that can deanonymize users, a common failure point in custom implementations.
Examine how your ring signatures interact with wallets, RPC calls, and frontends for side-channel data leaks, ensuring end-to-end privacy from transaction construction to broadcast.
Optimize the on-chain computational and storage footprint of ring signature verification, reducing gas costs for users—a critical factor for mainnet adoption and scalability.
Ensure your implementation aligns with established cryptographic standards and best practices, providing a verifiable foundation for security audits and regulatory due diligence.
Identify and provide remediation for common coding errors in finite field arithmetic, random number generation, and signature aggregation that generic auditors often overlook.
Our structured audit packages are designed to meet the security needs of projects at every stage, from early development to enterprise-grade production systems.

Secure, production-ready smart contracts built for your specific business logic and audited for deployment.
We architect and deploy custom smart contracts that power your token, DeFi protocol, or NFT platform. Our development process is built on security-first principles using Solidity 0.8+ and OpenZeppelin libraries, ensuring your core logic is robust and upgradeable.
From initial concept to mainnet launch, we manage the full lifecycle with clear deliverables and milestones.
ERC-20, ERC-721, ERC-1155, or bespoke contracts for unique use cases.Get clear answers about our specialized audit process, timeline, and security guarantees for privacy-preserving protocols.
Our audit follows a four-phase methodology tailored for privacy protocols: 1) Architecture Review of the cryptographic design and anonymity set management. 2) Code-Level Analysis for vulnerabilities like linkability flaws, parameter misuse, and side-channel risks. 3) Mathematical Verification of the zero-knowledge proofs and ring signature logic. 4) Integration Testing against the broader protocol (e.g., mixer, voting). We use both manual review by cryptographers and automated tools like static analyzers and custom fuzzers.
