Baby Shiba Inu - Smart Contract Audit Report

Summary

LITH Audit Report Baby Shiba Inu ($BabyShibaInu) is a new community-driven DeFi token on the Ethereum Blockchain that is an automatic liquidity providing protocol that pays out static rewards to holders.

Baby Shiba Inu's contract is deployed at 0xAECf6d1afF214feF70042740054f0f6D0Caa98Ab on the Ethereum mainnet.

Notes on the Contract:
The total supply of the token is initially set to one quadrillion $BabyShibaInu [1,000,000,000,000,000].
No minting or burn functions are present; and holders are not allowed to send tokens to the burn address. Tokens may be sent to the burn address upon deployment.
50% of the total $BabyShibaInu supply was burned upon deployment.
At the time of writing, 3.89% of the total supply is in PancakeSwap V2 Liquidity.
77.3% of that liquidity is locked in the zero address.
16.4% of that liquidity is in an unverified contract.
There is a "Dev Wallet" that has 4.63% of the total supply which is more than the amount of $BabyShibaInu that is in liquidity.

There is a "maximum token amount" that can be held in a given wallet at any point in time. This amount can be changed by any user who decides to use the "set max wallet percent" function. Any addresses that are "excluded" from fees are also exempt from this maximum token amount.
Any user has the ability to set and update the maximum transaction percent at any time, which will impose a limit to the number of tokens that can be transferred during any given transaction.
There is a 2% 'Tax Fee', 3% 'Dev Fee', 2% 'Burn Fee' and a 6% 'Liquidity Fee' on all transactions for any "non-excluded" addresses that participate in a transfer. The owner has the ability to modify these fees to any percentage at any time. (However, ownership is now the 0 address so this change will not occur).
The tax fee is redistributed to existing token holders instantly and automatically at the time of each transaction.
The dev fee is sent to the "Dev Wallet" instantly and automatically at the time of each transaction.
There is no burn that occurs as a result of this "Burn Fee". This fee simply reduces the amount of tokens that a recipient will receive from the sender in a transaction. However, that 2% is never sent anywhere, and it is not subtracted from the sender's balance.
The liquidity fee charged on transactions is stored in the contract and, once a threshold value is met, 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 threshhold 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 these newly created LP tokens (as a result of this process) is the Owner of the contract. Since ownership is now renounced, the LP tokens from this process are now considered locked with the 0 address.
The owner of the contract can exclude and include accounts from transfer fees and reward distribution.
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 can additionally be restored (even if ownership was previously renounced), by using the unlock function a second time.
Ownership has been renounced.
The contract utilizes SafeMath libraries along with following the BEP20 standard.
Audit Findings Summary
Any address can interact with the contract to modify the maximum wallet amount as well as the maximum transaction amount.
Ensure trust in the team as the "Dev Wallet" contains more $BabyShibaInu than the amount that is currently in liquidity, and their wallet will continue to collect reflections and fees over time.
