Starknet React Rules Skill

Iron Laws

NEVER interact with Starknet contracts without validating the connected wallet and chain ID
ALWAYS handle transaction pending, confirmed, and rejected states explicitly
NEVER hardcode contract addresses — always use environment variables or config files
ALWAYS use TypeScript types generated from ABI for contract interactions
NEVER skip error handling for wallet connection failures and transaction reverts

Anti-Pattern	Why It Fails	Correct Approach
Skipping chain ID validation	Wallet connected to wrong network silently corrupts transactions	Always validate chainId matches expected Starknet network
Hardcoding contract addresses	Breaking changes when deploying to different environments	Use environment variables or config files for all contract addresses
Missing transaction state handling	Users see blank UI during pending/rejected states	Implement loading, confirmed, and rejected state for all transactions
Direct ABI calls without TypeScript types	Runtime errors from wrong argument types	Use TypeScript types generated from ABI for all contract calls
Ignoring wallet connection errors	Silent failures create confusing UX	Always handle ConnectionError, UserRejectedRequestError, and RejectedRequestError
