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:
- Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
- Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
- Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
- Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
- Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
- Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
- 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 change the fee wallet address.
- The owner can change the status of a transaction at any time, which means the owner is in complete control of the transactions. For example, the owner can change the status to "Delivered" or "Released" on behalf of escrow transaction creators.
- The admin can either release the funds to the seller manually or return them back to the buyer's wallet.
Note - This Audit report consists of a security analysis of the HelloEscrow 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 Hello Escrow team. Our team did not audit other contracts associated with the project. We recommend investors to do their own research before investing.

Findings and Audit result
medium Issues | 1 findings
Resolved
#1 medium Issue
Logical Error
tThe value "is_admin_allow" is never set to true in the contract, which will cause the transaction to revert. The functionality is supposed to work only after the admin's permission if the transaction was created using it, but the problem exists in the implementation where the admin can not manually set this permission to 'true'.

Missing Arithmetic Events
Emitting events are necessary for any critical parameter change in the contract. In this case, the owner can change the status of a transaction, so it is important to emit an event here.
