Summary and Final Words

No crucial issues found

The contract does not contain issues of high or medium criticality. This means that no known vulnerabilities were found in the source code.

Contract owner can mint

It is possible to mint new tokens.

Contract owner cannot blacklist addresses.

It is not possible to lock user funds by blacklisting addresses.

Contract owner cannot set high fees

The fees, if applicable, can be a maximum of 25% or lower. The contract can therefore not be locked. Please take a look in the comment section for more details.

Contract cannot be locked

Owner cannot lock any user funds.

Token cannot be burned

There is no burning within the contract without any allowances

Ownership is not renounced

The owner retains significant control, which could potentially be used to modify key contract parameters.

Scope of Work

This audit encompasses the evaluation of the files listed below, each verified with a SHA-1 Hash. The team referenced above has provided the necessary files for assessment.

The auditing process consists of the following systematic steps:

  1. Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
  2. Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
  3. Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
  4. Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
  5. Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
  6. Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
  7. Actionable Recommendations: Provide detailed, specific, and actionable steps to secure and optimize the smart contracts.

A file with a different Hash has been intentionally or otherwise modified after the security review. A different Hash may indicate a changed condition or potential vulnerability that was not within the scope of this review.

Final Words

The following provides a concise summary of the audit report, accompanied by insightful comments from the auditor. This overview captures the key findings and observations, offering valuable context and clarity.


Ownership Privileges
  • The owner can mint an unlimited amount of tokens after initial deployment.
  • The owner can burn his tokens.

Note - This Audit report consists of a security analysis of the Metalink Token smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the Metalink team, other contracts associated with the project were not audited by our team. We recommend investors to do their own research before investing.

Findings and Audit result

medium Issues | 1 findings

Pending

#1 medium Issue
Owner can mint unlimited tokens.
BEP20Token.sol
L497-500
Description

The owner can mint new tokens after the initial deployment, which is not recommended as this can manipulate the supply of tokens and because of this, the price of the token can be manipulated.

low Issues | 2 findings

Pending

#1 low Issue
Local variables shadowing (shadowing-local)
BEP20Token.sol
L351
L351
L351
L351
L419
L578
Description

Rename the local variables that shadow another component.

Pending

#2 low Issue
Old compiler version.
BEP20Token.sol
L2
Description

Adding the latest constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.

optimization Issues | 1 findings

Pending

#1 optimization Issue
Public function that could be declared external (external-function)
