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.

Note - This Audit report consists of a security analysis of the HowToPay 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 HowToPay team. Other contracts associated with the project were not audited by our team. We recommend investors do their own research before investing.

Findings and Audit result

#1 medium Issue
Transfer of tokens without enabling trade.
HTP
L434-463
Description

The trading needs to be enabled by the owner in order for regular users to transfer tokens. On the contrary, the owner can authorize addresses manually and those addresses will be able to trade tokens. This functionality can be exploited in the following way, For example, there is a presale and the wallets used for the presale can be authorized by the owner. All the tokens obtained can be consolidated into a final wallet address and facilitate trading and selling of the acquired tokens, the last wallet address can be authorized.

Pending

#2 medium Issue
Liquidity is added to externally owned address.
HTP.sol
L452-459
Description

The contract's liquidity is automatically added to the 'Owner's' address, which is not recommended because, in an extreme scenario, this can be used to drain liquidity from the contract.

#1 low Issue
Floating pragma solidity version.
HTP.sol
L7
Description

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the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.
