Bull Bear Info
Bull & Bear AI is developed using AI to predict the BULL and BEAR markets through User Behaviors and Price Action, generating profit for users. AI will be trained based on historical data of users and price line history, along with market movements to make the most accurate predictions. BullBear AI is a revolution in the Arbitrum Ecosystem. The purpose of the project is to provide AI tools for users to apply to trading and prediction, thereby creating value and profit.

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
- Launch contract but cannot stop it
- Set buy and sell fees to any arbitrary value including 100% or more which is not recommended
- Set fee receiver addresses
- Allow wallets to add liquidity/transfer tokens before the contract is launched by the owner
- Include/Exclude accounts from Fees
- Add/Remove pair addresses
- Withdraw any type of token from the contract
We recommend users to do their own research before investing
Note for Investors: We only Audited a token contract for the Bull and Bear Team. However, If the project has other contracts (for example, a Presale contract etc), and they were not provided to us in the audit scope then we cannot comment on its security and we are not responsible for it in any way.

Findings and Audit result
medium Issues | 1 findings
Pending
#1 medium Issue
Fees can be 100% or more
The owner is able to set the fees to 100% or more which is not recommended because if done so then the users will lose their funds while buying/selling the tokens. We recommend putting a maximum limit of 25% or less to which the fees can be set.
low Issues | 3 findings
