During this technological era, the scalability of blockchain networks has opened up a world of business possibilities and paved the way to endless use cases across all industries. The tokenization of asset classes eliminates intermediaries, transparency, decentralization, authenticity, and traceability. All of the blockchain technical features created a unique experience that offers users unlimited possibilities in how they interact with the internet. Additionally, technology like smart contracts allowed a significant advancement in developing Decentralized applications (Dapps) that operate with complete transparency and without the need to store users' data. Sports betting is a significantly large sector with a market size of 194.63 billion U.S dollars in 2021, which has been steadily growing to 231.33 billion USD in 2022. The market is growing exponentially, attracting users around the globe.

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 burn function within the contract.

Ownership is renounced

Contract cannot be manipulated by owner functions.

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.


  • SafeMath library is not needed in pragma version above 0.8.x
  • Owner is able to
    • blacklist addresses with "blockBots" function
  • Ownership is renounced: See Tx
  • In that case that the ownership is renounced (See above TX) the owner is not able to blacklist anymore
