Rao Cash
Rao Cash is the world's first decentralized payment money and an innovative global community network for financial freedom and independence in our daily lives, built on the Binance Smart Chain, (BEP-20) with an extremely fast 3-second block time and cheaper gas fees than ethereum. Designed to distribute money transfers and payments around the world with automatic money making in your wallet. With our RAO, people will be able to own decentralized money and not depend on governments, central banks and other such organizations. Cryptocurrencies are now considered almost the best form of digital money with which you can earn and simply get high returns on your investments in the future.

Note - This Audit report consists of a security analysis of the Rao Cash Token smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the Rao Cash team, other contracts associated with the project were not audited by our team. We recommend investors to do their own research before investing.
Audit Scope
This audit covered the following files listed below with a SHA-1 Hash. The above token Team provided us with the files that needs to be tested.
We will verify the following claims:- Correct implementation of Token standard
- Deployer cannot mint any new tokens
- Deployer cannot burn or lock user funds
- Deployer cannot pause the contract
- Overall checkup (Smart Contract Security)
- Review of the specifications, sources, and instructions provided to SolidProof to make sure we understand the size, scope, and functionality of the smart contract.
- Manual review of code, which is the process of reading source code line-by-line in an attempt to identify potential vulnerabilities.
- Comparison to specification, which is the process of checking whether the code does what the specifications, sources, and instructions provided to SolidProof describe.
- Test coverage analysis, which is the process of determining whether the test cases are actually covering the code and how much code is exercised when we run those test cases.
- Symbolic execution, which is analysing a program to determine what inputs causes each part of a program to execute.
- Best practices review, which is a review of the smart contracts to improve efficiency, effectiveness, clarify, maintainability, security, and control based on the established industry and academic practices, recommendations, and research.
- Specific, itemized, actionable recommendations to help you take steps to secure your smart contracts.
A file with a different Hash has been modified, intentionally or otherwise, after the security review. A different Hash could be (but not necessarily) an indication of a changed condition or potential vulnerability that was not within the scope of this review.

Audit Details
Throughout the review process, care was taken to evaluate the repository for security-related issues, code quality, and adherence to speciïŹcation and best practices. To do so, reviewed line-by-line by our team of expert pentesters and smart contract developers, documenting any issues as there were discovered.
Risk represents the probability that a certain source-threat will exploit vulnerability, and the impact of that event on the organization or system. Risk Level is computed based on CVSS version 3.0.
