Smart Contract Audit Report
ShibaPepe is a new ERC-20 token on Ethereum.
For this audit, we reviewed the project team's TaxableERC20 contract at 0x7eE68A5B4F11365B361e32c6D6fE3fb4973e4524 on the Ethereum Mainnet.
No findings were identified.
Date: May 15th, 2023.
- The total supply of the token is set to 1 quadrillion $SHEPE [1,000,000,000,000,000].
- No mint or burn functions are accessible, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
- At the time of writing this report, 100% of the total supply belongs to the deployer.
- Ownership has been renounced by the team.
- Although a Tax fee is present in the contract, its percentage is permanently set to zero.
- The owner was previously able to set the Tax fee to any percentage up to 99.9% at any time.
- The owner was previously able to include and exclude accounts from the Tax fee at any time.
- The owner was previously able to set the team's Fee wallet to any address at any time.
- As the contract is deployed with Solidity v0.8.19, it is protected from overflows/underflows.
- The contract complies with the ERC-20 token standard.

What is a SourceHat Audit?
Typically, a smart contract audit is a comprehensive review process designed to discover logical errors, security vulnerabilities, and optimization opportunities within code. A SourceHat Audit takes this a step further by verifying economic logic to ensure the stability of smart contracts and highlighting privileged functionality to create a report that is easy to understand for developers and community members alike.
How Do I Interpret the Findings?
Each of our Findings will be labeled with a Severity level. We always recommend the team resolve High, Medium, and Low severity findings prior to deploying the code to the mainnet. Here is a breakdown on what each Severity level means for the project:
- High severity indicates that the issue puts a large number of users' funds at risk and has a high probability of exploitation, or the smart contract contains serious logical issues which can prevent the code from operating as intended.
- Medium severity issues are those which place at least some users' funds at risk and has a medium to high probability of exploitation.
- Low severity issues have a relatively minor risk association; these issues have a low probability of occurring or may have a minimal impact.
- Informational issues pose no immediate risk, but inform the project team of opportunities for gas optimizations and following smart contract security best practices.
