Beedle - Oracle free perpetual lending

Summary

This contract implements the Beedle token, which is an ERC20 token with additional features provided by OpenZeppelin's ERC20Permit and ERC20Votes extensions. The contract also inherits from a custom Ownable contract.

Vulnerability Details

Ownership Transfer Vulnerability: The contract inherits from the Ownable contract, which allows the current owner to transfer ownership to another address using the transferOwnership function. If the ownership is transferred to an untrusted or malicious address, it could lead to the loss of control over the contract.

Impact

Ownership Transfer Vulnerability: If the ownership is transferred to an unauthorized or malicious entity, they could potentially modify critical contract functions or drain the token's funds.

Tools Used

this is a manual audit and documentation based audit

Recommendations

Ownership Transfer: Consider carefully whether the ownership transfer feature is necessary for the contract's functionality. If it is not required, remove the Ownable inheritance and the transferOwnership function to prevent unauthorized ownership transfers.

Security Review: Conduct a comprehensive security review of the contract, including third-party dependencies such as the OpenZeppelin contracts, to ensure the absence of other vulnerabilities.

Testing: Thoroughly test the contract's functionality and interactions with other contracts on different networks to identify any potential edge cases or issues.

Code Review: Engage external auditors or experienced Solidity developers to review the contract code and provide additional feedback on its security.

Bug Bounty: Consider setting up a bug bounty program to incentivize security researchers to identify and responsibly disclose any vulnerabilities they may find.
