OpenZeppelin Skills

Authoritative knowledge of audited OpenZeppelin smart contract libraries.

Provides comprehensive reference knowledge for the OpenZeppelin Contracts library, the most widely used smart contract framework. Covers ERC-20, ERC-721, ERC-1155 token standards, access control patterns (Ownable, AccessControl, roles), upgradeable contract patterns (UUPS, Transparent Proxy), governance (Governor, TimelockController), and security utilities.

Key Contract Categories

Token Standards

• ERC-20 - Fungible tokens with extensions (Burnable, Capped, Pausable, Permit, Votes, Wrapper)
• ERC-721 - NFTs with extensions (Enumerable, URIStorage, Burnable, Pausable, Votes)
• ERC-1155 - Multi-token standard with batch operations

Access Control

• Ownable - Single-owner access control
• AccessControl - Role-based access control with admin hierarchy
• AccessManaged - Centralized authority management

Upgradeability

• UUPS Proxy - Universal Upgradeable Proxy Standard
• Transparent Proxy - Admin-separated upgrade pattern
• Beacon Proxy - Shared implementation upgrades

Governance

• Governor - On-chain governance framework
• TimelockController - Time-delayed execution
• Votes - Vote tracking and delegation
