OpenZeppelin Audits

Overview

OpenZeppelin is widely trusted in smart contract security, known both for creating the industry-standard OpenZeppelin Contracts library used by thousands of projects and for providing security audit services. Founded by security researchers and Ethereum core contributors, OpenZeppelin has audited hundreds of high-profile projects including Ethereum Foundation, Coinbase, TheGraph, Aave, Compound, and many large DeFi protocols.

OpenZeppelin's security team has both created security patterns used across the industry and audited critical blockchain infrastructure. Their combination of deep protocol knowledge, audit experience, and contributions to Ethereum security standards makes them a strong choice for projects requiring high security assurance.
