solidity-security

預期結果:

• Confirm reentrancy protection on withdraw and external calls
• Verify access control on admin functions
• Check overflow safety for arithmetic operations
• Ensure input validation for recipients and amounts
• Review event emission for state changes

預期結果:

• Solidity 0.8+ has built-in overflow protection that reverts automatically
• For versions below 0.8, use OpenZeppelin's SafeMath library
• Always validate inputs before arithmetic operations
• Use require statements to check bounds on transfers

預期結果:

• Inherit from OpenZeppelin's Ownable contract for owner-only functions
• Create custom role-based access with the AccessControl contract
• Use modifiers like onlyOwner or onlyAdmin to restrict access
• Emit events for all privileged actions for transparency
