Solidity Coding Standards

Language Rule

• Always respond in the same language the user is using. If the user asks in Chinese, respond in Chinese. If in English, respond in English.

Coding Principles

• Pragma: Use pragma solidity ^0.8.19; — keep consistent across all files in the project
• Dependencies: OpenZeppelin Contracts 4.9.x, manage imports via remappings.txt
• Error Handling: Prefer custom errors over require strings — saves gas and is more expressive
  • Define: error InsufficientBalance(uint256 available, uint256 required);
  • Use: if (balance < amount) revert InsufficientBalance(balance, amount);
• Documentation: All public / external functions must have NatSpec (@notice, @param, @return)
• Event Indexing: Only add indexed to address type parameters — add comment if indexing other types
• Special Keywords: immutable / constant / unchecked / assembly must have inline comment explaining why
