Summary: Analyzed for common Solidity vulnerabilities in utility functions related to tokens.

Vulnerability Details:

• Unchecked Arithmetic: SWC-101: Potential for arithmetic operations to cause overflows/underflows.
  Severity: Medium

  uint256 newBalance = tokenBalance - amount;

  Line: 42

• Reentrancy Risks: SWC-107: External calls during token transfers may be vulnerable.
  Severity: High

  (bool success, ) = token.call(abi.encodeWithSignature("transfer(address,uint256)", to, amount));

  Line: 65

Impact: Could lead to incorrect token balances or reentrancy attacks.

Tools Used: Manual code inspection.

Recommendations:

• Arithmetic Fix: Use safe math libraries to prevent overflows and underflows.

  uint256 newBalance = SafeMath.sub(tokenBalance, amount);

• Reentrancy Fix: Implement ReentrancyGuard for critical functions.
