0xGuard began as a passion project by DeFi professionals with deep expertise in smart contract security and a vision to bring reliability and affordability together in the audit market. Now a respected player in the blockchain space, 0xGuard offers security and KYC services for projects at any stage—from early startups to large-scale protocols.

Among their publicly shared audits are high-profile projects like Grape Finance, MistSwap, SummitSwap, and MiniVerse, showcasing their ability to work with complex contracts and high-volume ecosystems. Each report identifies severity levels and offers specific recommendations, helping teams ship resilient, secure smart contracts.
