OpenZeppelin Contracts is a library of modular, secure, and reusable smart contract components designed for the development of decentralized applications. It provides a foundational framework for building standard-compliant contracts, offering battle-tested implementations for token standards, access control, and common utility patterns. The project distinguishes itself through its comprehensive support for complex architectural patterns, including proxy-based upgradeability, role-based access control, and account abstraction. It enables developers to implement modular logic injection via hoo
Enables users to authorize operations off-chain via cryptographic signatures, allowing third-party relayers to execute transactions without requiring native gas tokens.
