CertiK

CertiK is a New York-based Web3 and blockchain security firm founded in 2018 by computer science professors Zhong Shao of Yale and Ronghui Gu of Columbia, with about 210 employees and roughly $296 million raised from investors including Insight Partners, Tiger Global, Sequoia, Coatue, Advent International, Goldman Sachs, Lightspeed and SoftBank Vision Fund 2, at a $2 billion valuation set in 2022. Its products include smart contract audits, penetration testing, the Skynet security monitoring platform, KYC services and a Security Leaderboard. On Canton, CertiK audited the Daml smart contracts and off-chain components that implement Circle's xReserve integration, which mints the USDCx stablecoin, along with the whole Digital Asset Registry, with that work completed in December 2025, and ran penetration testing of the off-chain application and infrastructure behind USDCx. It completed a further audit of the Digital Asset Registry's on-chain and off-chain components in July 2026, with the final report delivered on August 13, 2026. CertiK also works with teams targeting CIP-56 compatibility, including USDCx, Temple, Interstice-digital, Cancore and Eesee, and published a guide to where CIP-56 security actually lives, explaining how Daml views, choices, factories, client-side construction and operational permissions determine the security of CIP-56 assets. It tracks the Canton Network Token Standard as it evolves, including CIP-0112 (Token Standard V2), approved on June 12, 2026.
