ERC-20 Token Integration for Scaffold-ETH 2

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.

Overview

ERC-20 is the standard interface for fungible tokens on Ethereum. This skill covers adding an ERC-20 token contract to a Scaffold-ETH 2 project using OpenZeppelin's ERC-20 implementation, along with deployment scripts and a frontend for interacting with the token.

For anything not covered here, refer to the OpenZeppelin ERC-20 docs or search the web. This skill focuses on what's hard to discover: SE-2 integration specifics, common pitfalls, and ERC-20 gotchas that trip up both humans and AI.

Dependencies

OpenZeppelin contracts are already included in SE-2's Hardhat and Foundry setups, so no additional dependency installation is needed. If for some reason they're missing:

• Hardhat: @openzeppelin/contracts in packages/hardhat/package.json
• Foundry: installed via forge install OpenZeppelin/openzeppelin-contracts, with remapping @openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/
