OpenZeppelin Contracts is a library for secure smart contract development on EVM. Use via inheritance (e.g. ERC20, AccessControl) or using for (e.g. ECDSA, Math). Covers access control (Ownable, RBAC, AccessManager, TimelockController), tokens (ERC20, ERC721, ERC1155, ERC4626, ERC6909), upgradeable variants, and utilities (crypto, math, introspection, structures, storage).
