Hash2O Info
Hash20 is designed in such a way to open door of DeFi for everyone; making the decentralized financial world accessible for all; through a multi chain yield processing Hash: Hash20. The core idea behind the structure of this project, is to provide Hashers (The community of investors who invests through Hash20) the ease of investing in liquidity pools; without having to go through the hustle of wasting time and money in finding the right liquidity pool. Thus creating a safe and reliable atmosphere for novice investors; regardless of the hostilities in the DeFi space. Hash20 offers a judicious initiative, that operate through a set of algorithms that automatically diversify investments in reliable protocols. In a nutshell, the benefits gained through MetaHash are: Diversification of the portfolio, minimized risk, lower fee, life-time reward generation, NFT staking, lesser hustle and bustle, and lastly, eradication of unlimited time spent on research.

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.
