Secure, production-ready smart contracts built by Web3 experts to power your decentralized applications.
We architect and deploy audit-ready smart contracts for tokens, DeFi protocols, and NFT ecosystems. Our development process ensures security and gas efficiency from day one.
ERC-20, ERC-721, ERC-1155, and bespoke standards.OpenZeppelin libraries.Deploy with confidence using battle-tested patterns and comprehensive test suites.
We provide a full delivery package:
Ethereum, Polygon, Arbitrum, and other EVM chains.Our methodology is engineered for the unique complexities of zero-knowledge circuits and smart contracts, delivering actionable security insights that reduce risk and accelerate your go-to-market.
Zero-Knowledge circuits introduce unique cryptographic and logical risks. Our focused expertise delivers the depth of review required to secure your most critical on-chain logic.
ZK proofs are computationally expensive. We identify optimization opportunities in your circuit design and verifier contracts, reducing on-chain verification costs by 20-40% on average.
Our team has secured high-value ZK rollups, private voting systems, and confidential DeFi pools. This battle-tested experience directly informs our audit methodology and checklists.
Our tiered audit packages are designed to match the complexity of your ZK circuits and the criticality of your application, from new protocols to high-value enterprise systems.

Common questions from CTOs and engineering leads evaluating zero-knowledge proof smart contract security audits.
We employ a multi-layered methodology: 1) Architecture Review: Assess circuit design, constraint system, and integration points. 2) Manual Code Review: Line-by-line analysis of Solidity, Circom, or Noir code for logic flaws and cryptographic soundness. 3) Formal Verification: Use tools like Picus and Certora to prove specific properties. 4) Differential Fuzzing: Compare circuit outputs against a reference implementation. 5) Gas & Optimization Review: Identify inefficiencies in proof generation and verification. Our process is based on the NIST Cybersecurity Framework and covers 100+ vulnerability patterns specific to ZK systems.
