SAUDI PEPE
Smart Contract Audit Report
Audit Summary
SAUDI PEPE is a new ERC-20 token on Ethereum.
For this audit, we reviewed the project team's SAUDIPEPE contract at 0x8acee0fcee91cedad1c5013f031762c814740587 on the Ethereum Mainnet.
Audit Findings
An Informational finding was identified and the team may want to review it.
Date: May 8th, 2023.Finding #1 - SAUDIPEPE - Informational
Description: Although the SafeMath library is utilized, the contract is deployed with Solidity v0.8.19 which has built-in overflow checks.
Recommendation: SafeMath could be safely removed to reduce contract size, deployment costs, and gas costs on all transactions that utilize it.
Contract Overview
- The total supply of the token is set to 10 billion [10,000,000,000] $SAUDIPEPE.
- No mint or burn functions exist, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
- At the time of writing this report, there are 114 total token holders. The token allocation is as follows:
- 20% of the total supply has been sent to the 0x..dead address.
- 7.47% of the total supply is in Uniswap liquidity.
- Of that liquidity, 100% of the LP tokens are permanently locked in a TrustSwap token locking contract.
- The next five EOAs own a cumulative 8.7% of the total supply.
- Ownership has been renounced by the team.
- Although a buy fee and sell fee are present in the contract, both of their fee percentages are permanently set to zero.
- The tokens previously collected through the buy fee and sell fee were sent to the owner.
- The owner was previously able to set the buy fee and sell fee to any percentages at any time.
- The owner was previously able to exclude/include accounts from the buy fee and sell fee 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.
