Not Another Shit Altcoin Token - Smart Contract Audit Report

Summary

Not Another Shit Altcoin ($NASA) is a new community-driven token on the Binance Smart Chain that is an automatic liquidity providing protocol that pays out static rewards to holders.

Not Another Shit Altcoin's Token contract is deployed at 0xd78c8961131c6d582d203edddeaabc83065d032a on the Binance Smartchain mainnet.

Notes on the Contract:
The total supply of the token is initially set to 1 trillion $NASA [1,000,000,000,000].
No minting or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
At the time of writing this report, 100% of the total $NASA token supply is in possession of the owner as the project was recently deployed.

There is a 'tax fee' and a 'liquidity fee' on all transactions for any address that participates in a transfer. The owner has the ability to modify these fees to any percentage at any time.
The breakdown of the tax fee is segmented into three portions as follows:
1/2 is redistributed to existing token holders.
1/3 is sent to the team's 'marketing' wallet.
1/6 is sent to the team's 'rugPullFund' wallet.
The liquidity fee charged on transactions is stored in the contract and, once a threshold value is met, is used to fund Pancakeswap liquidity. This functionality can be enabled/disabled by the owner.
Liquidity-adds are funded by selling a portion of the tokens collected as fees (after the threshold as determined by the owner is met), then pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
The recipient of the newly created LP tokens is the owner of the contract.

The owner of the contract can exclude and include accounts from transfer fees and reward distribution.
The owner has the ability to set and update a maximum transaction percent at any time, which will impose a limit to the number of tokens that can be transferred during any given transaction.
This maximum transaction amount does not apply to the owner during transactions where the owner is either the sender or the recipient.
The owner has the ability to use the "lock" function in order to temporarily set ownership to address(0). Ownership is restored after the duration of time determined by the owner has passed and they use the 'unlock' function.
Ownership has not been renounced.
The contract utilizes SafeMath libraries along with following the BEP20 standard.
The calculation that is used to send funds from the tax fee to the marketing wallet, utilizes a multiplication after a division which could cause a lack of precision for the values that are sent to the marketing wallet. Our team recommends simplifying this calculation by only applying division.
Audit Findings Summary
No external threats were identified.
We recommend that the team renounces ownership.
Please ensure trust in the team prior to investing as they have substantial control in the ecosystem.
