## Questions

### Is OpenZeppelin a security auditor or an infrastructure company?

Both. The firm’s open-source Contracts library is free infrastructure that 64% of active wallets interact with. On top of that, it sells professional security audits, a Defender operations platform for transaction relaying and monitoring, and advisory services. The library creates the funnel; the paid services monetize the most demanding compliance and security needs.

### What is the scale of assets secured by OpenZeppelin audits?

OpenZeppelin reports that security audits have protected over $250 billion in total value locked. The Contracts library has facilitated more than $33 trillion in cumulative value transferred onchain, driven by its adoption as the default standard for stablecoins and tokenized funds.

### Which major protocols or foundations rely on OpenZeppelin?

Disclosed relationships include the Ethereum Foundation, Uniswap Foundation, ZKsync (Matter Labs), Arbitrum, StarkWare, Stellar, and The Graph. Nine of the top ten stablecoins and ten of the top ten tokenized funds by market capitalization are built with OpenZeppelin Contracts.

### Does OpenZeppelin participate in zero-knowledge-proof security?

Yes. In 2024 it announced its entry into ZK-proof audits, complementing the existing smart-contract, infrastructure, and governance security review practices. This expands the firm’s coverage beyond Solidity to privacy-preserving and scaling architectures.

### What open-source public goods does OpenZeppelin maintain?

Beyond the Contracts library, OpenZeppelin runs Ethernaut, a gamified security education platform with over 140,000 plays. It has contributed to Ethereum standards on account abstraction (ERC-1271), metatransactions (ERC-2771), and upgradeability (ERC-7201, ERC-1967), and participates in the SEAL 911 emergency response collective.
