Audit Findings

No findings were identified.
Date: October 14th, 2022.
Updated: November 21st, 2022 to reflect the project's Mainnet address.

Contract Overview

• The total supply of the token is set to 1 billion $MAGA [1,000,000,000].
• No public mint or burn functions are present, though the circulating supply can be decreased by sending tokens to the 0x..dead address.
• At the time of writing this report, 74.2% of the total supply belongs to an unverified Pinksale Presale contract.
• The remaining 25.8% of the total supply is stored in a Pinksale token-locking contract.


• There is a 5% transfer fee charged on all sells via Uniswap where neither the sender nor the recipient is excluded from fees.
• The tokens collected through the transfer fee are stored in the contract address. The tokens are swapped for ETH and sent to the team's Marketing wallet when the following conditions are met:
  • The threshold number of tokens (determined by the owner) in the contract address has been reached.
  • The contract is not currently swapping tokens.
  • The caller is not initiating a buy transaction via Uniswap.
  • The owner is neither the sender nor the recipient of the transfer.
• As the contract is implemented with Solidity v0.8.x, it is safe from any possible overflows/underflows.
• The contract complies with the ERC-20 token standard.

Ownership Controls:

• The owner can enable/disable the transfer fee at any time.
• The owner can exclude and include accounts from the transfer fee.
• The owner can update the threshold number of tokens that triggers the automatic token swapping functionality to any value at any time.
• The owner can set the team's Marketing wallet to any address at any time.

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.
