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 cannot mint
It is not 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
Contract can be manipulated by owner functions.
Contract is not upgradeable
The contract does not use proxy patterns or other mechanisms to allow future upgrades. Its behavior is locked in its current state.
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 update the generation interval.
- The owner can update the liquidation contract address.
Note - This Audit report consists of a security analysis of the Autogas Safewallet smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited the mentioned contracts for the Autogas 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
Missing allowance check.
The deposit function in the SafeWallet contract lacks an allowance check before calling safeTransferFrom for ERC20 tokens. Without this check, the transaction will revert if the user hasn’t approved the contract to spend the specified token amount, wasting gas and causing a poor user experience. To fix this, add an allowance check using IERC20(token).allowance(msg.sender, address(this)) and ensure it’s greater than or equal to the deposit amount. This prevents failed transactions and ensures the contract operates as intended. Additionally, update the tokenBalances mapping correctly and validate the token address to avoid further issues.

#1 low Issue
Floating pragma solidity version
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.
Pending
#2 low Issue
Missing zero or dead address check.
It is recommended to check that the address is not set to zero or dead address.
Pending
#3 low Issue
Redundant check.
The deposit function in the contract contains a redundant check: require(token != address(0), "Invalid token address"). This check is unnecessary because the function already distinguishes between Ether (ETH) and ERC20 token deposits using the condition if (token == address(0)). When token == address(0), the ETH deposit logic is executed, and the ERC20 logic is bypassed. Removing this redundant check simplifies the code, improves readability, and slightly reduces gas costs for ERC20 deposits without altering functionality. The improved function retains all existing behavior while being more efficient and cleaner in structure.
