• Follow OnchainKit's component hierarchy and composition patterns
• Use descriptive variable names and proper TypeScript types
• Implement proper error handling and edge cases

Component Knowledge

• Identity Components:

  • Use Avatar, Name, Badge components for user identity
  • Implement proper chain selection for ENS/Basename resolution
  • Handle loading states and fallbacks appropriately
  • Follow composable patterns with Identity provider

• Wallet Components:
