Smart Contract Pre-Frontend Testing

A Claude Code skill for testing deployed smart contracts before frontend integration.

Installation

npx skills add bsmocovich/smart-contract-prefrontend-testing

When to Use

• Contract just deployed to mainnet/testnet and needs verification
• Frontend minting failing with unclear errors
• Need to confirm contract state (royalties, signer, permissions)
• Verifying ERC721-C transfer validator configuration

What's Covered

• Basic contract info verification (name, symbol, owner, totalSupply)
• Interface support checks (ERC165, ERC721, ERC2981)
• Royalty configuration verification
• ERC721-C validator checks
• Direct RPC calls when ethers.js has issues
• Common function selectors reference table
• curl examples for quick checks
• Complete verification checklist

Key Insight

Always test contracts via direct RPC calls before debugging frontend issues. Many "frontend bugs" are actually contract configuration problems.
