Summary

Identical identifier names across different contracts or libraries can lead to unexpected behavior and make your codebase harder to maintain.

Vulnerability Details

• Identifier shadowing due to duplicate name usage.

• Potential for execution errors and confusion in the codebase.

Impact

1. Unexpected Behavior: Duplicate identifiers may cause Solidity compiler issues, leading to incorrect or incomplete contract deployment.

2. Code Complexity: Conflicting identifier names can make your smart contracts harder to understand and maintain.

Tools Used

Solidity Unit Testing Compiler

Recommendations

1. Unique Identifier Names: Ensure each contract has a distinct name to avoid conflicts.

2. Refactor Contracts: Break down complex logic into separate, clearly named contracts for better code organization.
