⚠️ Found 5 issue(s): 3 Critical, 1 High, 1 Medium, 0 Low

🚨 Critical Issues

1. Integer Overflow Risk

• Line: 42
• Description: The contract uses Solidity version <0.8.0, which does not have built-in overflow/underflow protection. The mint function can cause an overflow when increasing totalSupply or balances.
• Fix: Upgrade to Solidity ^0.8.0 or use SafeMath for arithmetic operations.

2. Hardcoded Admin Key

• Line: 12
• Description: The contract has a hardcoded admin address, which can lead to centralization and potential abuse if the private key is compromised.
• Fix: Implement a proper access control mechanism using Ownable or similar patterns.

3. Reentrancy Vulnerability

• Line: 46
• Description: The withdraw function allows for reentrancy attacks as it calls an external address before updating the state.
• Fix: Update the state before making external calls. Use the Checks-Effects-Interactions pattern.

⚠️ High Severity Issues

1. Unchecked External Call

• Line: 56
• Description: The unsafeWithdraw function does not check the return value of the external call, which can lead to loss of funds if the call fails.
• Fix: Check the return value of the external call and handle failures appropriately.

⚡ Medium Severity Issues

1. Missing Zero Address Check (Line 66)
