OpenZeppelin

OpenZeppelin is the gold standard for smart contract security, providing audited contract libraries, security tooling, and professional audit services for projects building on HyperEVM and other EVM chains. The OpenZeppelin Contracts library—used by thousands of protocols worldwide—provides secure, gas-optimized implementations of ERC token standards, access control patterns, and DeFi primitives that HyperEVM developers rely on as foundational building blocks. OpenZeppelin Defender provides automated security operations including contract monitoring, automated incident response, and upgrade management through time locks and multi-sig governance.

Security infrastructure on Hyperliquid protects users and protocols through smart contract auditing, monitoring, and risk assessment. OpenZeppelin operates in this critical category that builds trust and safety across the HyperEVM DeFi stack — essential as TVL grows and protocols become more composable.
