Develop Smart Contracts with OpenZeppelin

Adapted from OpenZeppelin's official skill for Scaffold-ETH 2 Solidity projects.

Prerequisites

Check if ./packages/nextjs/scaffold.config.ts exists directly in the current working directory (do not search subdirectories). If it doesn't exist, this is not a Scaffold-ETH 2 project. Follow the instructions at https://docs.scaffoldeth.io/SKILL.md to scaffold it first. If it exists, continue directly with building.

Detect the Solidity framework flavor:

• If packages/hardhat exists → Hardhat flavor
• If packages/foundry exists → Foundry flavor

Core Principle: Prefer Library Components Over Custom Code

Before writing ANY contract logic, search the installed OpenZeppelin library for an existing component:

1. Exact match exists? Import and use it directly — inherit, override only what's needed
2. Close match exists? Import and extend — override only functions the library marks as virtual
3. No match? Only then write custom logic. Confirm by browsing the library's directory first
